[FIXED] How can I download a video from Facebook using GraphAPI?

Issue

I want to download a video from facebook to the clients local drive. I saw a few browser plugins and Facebook apps that are able to that and I was wondering how it can be done using the GraphAPI or in any other way.

Solution

First, you get the Graph API object. If the object is public, it's simple, just get https://graph.facebook.com/10151651550011063. (Where the number is the object's ID, equal to the ?v=OBJECTID in the facebook video URL.)

If the object is not public, you need a valid access_token, and the Graph API url becomes something like https://graph.facebook.com/10151651550011063?access_token=DFSDSGSFDGFGDSblabla

Then, in the Graph API object, you'll find the video download link under source.

[FIXED] How do you display closed caption format of HLS video stream from an m3u8 URL

Issue

I'm working on a Roku and TVOS app that is going to play HLS videos (VOD and live) as well as MP4. According to the Roku docs EIA-608 is supported on both and should also work on TVOS.

My question is, given URL to the m3u8 how can I tell what specific format (EIA-608,WebVTT etc) of closed captioning is being used in each stream?

Contents of the main m3u8 (note 1st stream says no CC, but it really does have it):

#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=380000,RESOLUTION=400x228,CODECS="avc1.66.30, mp4a.40.2",CLOSED-CAPTIONS=NONE
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_0_av.m3u8

http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_3_av.m3u8

Contents of the 1st stream's m3u8

#EXTM3U
#EXT-X-TARGETDURATION:4
#EXT-X-ALLOW-CACHE:YES
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:4.000,
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/segment1_0_av.ts
...

I can use ffprobe -hide_banner to show the 1st program's stream has closed captioning. Ex:

Duration: 00:02:36.76, start: 0.100511, bitrate: 0 kb/s
  Program 0
    Metadata:
      variant_bitrate : 380000
    Stream #0:0: Video: h264 (Constrained Baseline) ([27][0][0][0] / 0x001B), yuv420p, 400x228 [SAR 1:1 DAR 100:57], Closed Captions, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Metadata:
      variant_bitrate : 380000
    Stream #0:1: Audio: aac (LC) ([15][0][0][0] / 0x000F), 44100 Hz, mono, fltp, 48 kb/s
    Metadata:
      variant_bitrate : 380000

However, as you can see, Program 0 > Stream 0 just says that is has Closed captions - it does not list the type/spec of closed captioning technology being used.

How do I display the format of the Closed Captions?

Solution

WebVTT is what is know as a 'side car', or 'out of band' format. Meaning captions are in a separate file that you must download. You can see the URL for this file in the m3u8. Here the caption are part of the video stream itself. The only supported format in this case is EIA-608. ffmpeg support for 608 is pretty limited. The best tool I know of to for dealing with 608 is libcaption (full disclosure, I wrote it). I recently added a ts2srt example program. Fair warning its still sorta betaish.

[FIXED] How can I make my video loop in swift with playerViewController?

Issue

I am trying to loop a video with playerViewController on Swift for TVOS. I have the video playing fine, but I want to loop the video. Here is my code so far:

override func viewDidAppear(_ animated: Bool) {
    let videoURL = URL(string: "https://url-to-video.com/video.mp4")
    let player = AVPlayer(url: videoURL!)
    let playerViewController = AVPlayerViewController()
    playerViewController.player = player        self.present(playerViewController, animated: true) {
        playerViewController.player!.play()
    }
}

Any help is appreciated. Thanks

Solution

The quickest way to do this is to use an AVQueuePlayer with an AVPlayerLooper. You can set the player on your player view controller the same as you would with an ordinary AVPlayer, but you need to keep a persistent reference around to the looper so it’ll keep working. In other words, add this to your view controller’s interface:

var looper: AVPlayerLooper?

…and in your viewDidAppear, replace this:

let player = AVPlayer(url: videoURL!)

with this:

let player = AVQueuePlayer()
looper = AVPlayerLooper(player: player, templateItem: AVPlayerItem(asset: AVAsset(url: videoURL!)))

Then, once you start the player playing, its video will loop indefinitely.

[FIXED] How to loop video with AVPlayerLooper

Issue

I try to loop a video in a TV OS app with the AVPlayerLooper because this should get rid of the pause/hicup when playing the video again. I watched the WWDC2016 video https://developer.apple.com/videos/play/wwdc2016/503/ and try to implement the code but it doesn't loop. I have one PlayerViewController which inherits AVPlayerViewController. I put the code to let the video loop. If I have the following code, it shows nothing. If I change the second line to self.queuePlayer = AVQueuePlayer(playerItem:playerItem), it only plays once.

  let playerItem = AVPlayerItem(url: url as URL)
  self.queuePlayer = AVQueuePlayer()   //I declared this as a variable in the view controller
  self.playerLayer = AVPlayerLayer(player: self.queuePlayer) //I declared this as a variable in the view controller
  let playerLooper = AVPlayerLooper(player:  self.queuePlayer!, templateItem: playerItem)
  self.view.layer.addSublayer(self.playerLayer!)
  self.playerLayer?.frame = self.view.frame
  self.queuePlayer?.play()

Have any of you succeeded in playing looped video with the latest AVPlayerLooper?

Solution

I fixed the problem myself.

The playerLooper must be a member variable in the class otherwise it doesn't work because a local variable is gone after the method has been called. So I put this line at the beginning of the class to declare it. I didn't declare it as an AVPlayerLooper because this is only for tvos10.0 and newer versions. I want my class to be adaptive to tvos9.0. This is my working code.

var playerLooper: NSObject?
var playerLayer:AVPlayerLayer!
var queuePlayer: AVQueuePlayer?


func playVideo(_ filmName: String){
    if let path = Bundle.main.path(forResource: filmName, ofType: "mov") {
        let url =  URL(fileURLWithPath: path)

        if #available(tvOS 10.0, *) {

            // Use a new player looper with the queue player and template item
            let playerItem = AVPlayerItem(url: url as URL)
            self.player = AVQueuePlayer(items: [playerItem])
            self.playerLayer = AVPlayerLayer(player: self.player)
            self.playerLooper = AVPlayerLooper(player: self.player! as! AVQueuePlayer, templateItem: playerItem)
            self.view.layer.addSublayer(self.playerLayer!)
            self.playerLayer?.frame = self.view.frame
            self.player?.play()


        } else {
            // Fallback on earlier versions, this solution has hicup at end
            player = AVPlayer(url: url)
            player?.play()
            loopVideo(player!)
        }

Trying to make a square video through animationTool. See code below. The video is enlarged (https://i.stack.imgur.com/HscTk.jpg), how can i fix it?

let exportSession = AVAssetExportSession(asset: composition, presetName: AVAssetExportPresetHighestQuality)
        let strFilePath: String = generateMergedVideoFilePath()
        try? FileManager.default.removeItem(atPath: strFilePath)
        exportSession?.outputURL = URL(fileURLWithPath: strFilePath)
        exportSession?.outputFileType = .mp4
        exportSession?.shouldOptimizeForNetworkUse = true
        let mutableVideoComposition = AVMutableVideoComposition(propertiesOf: composition)
        mutableVideoComposition.instructions = instructions
        mutableVideoComposition.frameDuration = CMTimeMake(value: 1, timescale: 30)
        mutableVideoComposition.renderSize = CGSize(width: 1080, height: 1080)

        let parentLayer = CALayer()
        parentLayer.frame = CGRect(x: 0, y: 0, width: 1080, height: 1080)
        let videoLayer = CALayer()
        videoLayer.frame.size = videoSize
        videoLayer.position = parentLayer.position
        videoLayer.contentsGravity = .resizeAspectFill
        parentLayer.addSublayer(videoLayer)


        mutableVideoComposition.animationTool = AVVideoCompositionCoreAnimationTool(postProcessingAsVideoLayer: videoLayer, in: parentLayer)

Solution

mutableVideoComposition.renderSize = CGSize (width: 1080, height: 1080)

With this resolution, it takes the image relative to the top point, so I moved transform up

let coeConst = videoAssetWidth/videoAssetHeight
transform.translatedBy(x: -(videoAssetHeight-videoAssetHeight*coeConst)/2, y: 0)

[FIXED] How do I Add A GIF/Video To Landing Screen Background In Xcode 6 using swift?

Issue

what is the most efficient way to add a GIF/Video to the background of the landing screen ( home screen or first view controller) of my app in Xcode? i.e apps like spotify, uber, insagram etc. Being that my app is universal, how would i make it fit accordingly?

Solution

Do you mean the first screen that is displayed after your app is launched? If so: unfortunately you can't have dynamic content; you won't be able to use a gif/video.

That said, what you can do if you have some app-setup on background threads that will take some time anyway, or if you simply want the user to wait longer before interaction so that you can display the gif/video, you can make the static image match the first frame of the gif/video, and have your your entry point be a ViewController that displays the actual gif/video. Because this would delay the time to interaction, though, this would never be recommended.

As for making it fit: as of iOS 8 Apple recommends using LaunchScreen.xib. With it you can use Auto Layout to achieve universality.

To add a video you can use MPMoviePlayerController, AVPlayer, or if you're using SPritekit you can use an SKVideoNode.

EDIT (in response to follow-up comments):

An NSURL is a reference to a local or remote file. This link will give you a decent overview. Just copy the movie in and follow that guide.

In addition to the MPMoviePlayerController solution Saqib Omer suggested, here's an alternative method that uses a UIView with an AVPlayerLayer. It has a button on top of the video as an example, since that's what you're looking for.

import AVKit
import AVFoundation
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Start with a generic UIView and add it to the ViewController view
        let myPlayerView = UIView(frame: self.view.bounds)
        myPlayerView.backgroundColor = UIColor.blackColor()
        view.addSubview(myPlayerView)

        // Use a local or remote URL
        let url = NSURL(string: "http://eoimages.gsfc.nasa.gov/images/imagerecords/76000/76740/iss030-e-6082_sdtv.mov") // See the note on NSURL above.

        // Make a player
        let myPlayer = AVPlayer(URL: url)
        myPlayer.play()

        // Make the AVPlayerLayer and add it to myPlayerView's layer
        let avLayer = AVPlayerLayer(player: myPlayer)
        avLayer.frame = myPlayerView.bounds
        myPlayerView.layer.addSublayer(avLayer)

        // Make a button and add it to myPlayerView (you'd need to add an action, of course)
        let myButtonOrigin = CGPoint(x: myPlayerView.bounds.size.width / 3, y: myPlayerView.bounds.size.height / 2)
        let myButtonSize = CGSize(width: myPlayerView.bounds.size.width / 3, height: myPlayerView.bounds.size.height / 10)
        let myButton = UIButton(frame: CGRect(origin: myButtonOrigin, size: myButtonSize))
        myButton.setTitle("Press Me!", forState: .Normal)
        myButton.setTitleColor(UIColor.whiteColor(), forState: .Normal)
        myPlayerView.addSubview(myButton)
    }

[FIXED] How to create a gif from an image sequence without dither with FFMPEG?

Issue

I'm able to create a gif from the image sequence, but I'm struggling to remove the dither from it.

This is the command I'm using to create the gif:

ffmpeg -f image2 -framerate 24 -y -i image_%d.png -loop -1 "C:\Users\agetr\Documents\_tmp\__giuf.gif"

And I've tried to use the paletteuse=dither=none filter in different ways with no luck.

P.S.: I'm very new to the ffmpeg cli

Solution

You need to use -sws_dither none (after the -i $file argument, and before the output file). I've tried this on current git/master of FFmpeg and it works as expected, but on older builds (e.g. 4.4.1) this doesn't work. I don't know why exactly, so use a recent (5.0 or any version from 2022, if possible) version/build.

[FIXED] How to get video duration, dimension and size in PHP?

Issue

I want to know how to get the duration, dimension and size of uploaded video file in PHP. The file can be in any video format.

Solution

getID3 supports video formats. See: http://getid3.sourceforge.net/

Edit: So, in code format, that'd be like:

include_once('pathto/getid3.php');
$getID3 = new getID3;
$file = $getID3->analyze($filename);
echo("Duration: ".$file['playtime_string'].
" / Dimensions: ".$file['video']['resolution_x']." wide by ".$file['video']['resolution_y']." tall".
" / Filesize: ".$file['filesize']." bytes<br />");

Note: You must include the getID3 classes before this will work! See the above link.

Edit: If you have the ability to modify the PHP installation on your server, a PHP extension for this purpose is ffmpeg-php. See: http://ffmpeg-php.sourceforge.net/

Try this one!

.fiche-voyage {
    width: 100vw;
}
.voyage-image-row {
    width: 50%;
    display: flex;
    margin: 0 auto;
    justify-content: space-around;
}
.voyage-media-container {
    width: 50%;
    padding: 15px;
    text-align: center;
    display: flex;
    align-items: center;
}
.voyage-image,
.voyage-video {
    width: 100%;
}
.voyage-image:hover {
    transform: scale(2);
    transition: cubic-bezier(0.165, 0.84, 0.44, 1) 0.25s;
    z-index: 2;
}
.top{
    z-index: 1;
}

<div class="fiche-voyage">
    <div class=" voyage-image-row">
        <div class="voyage-media-container top">
            <div class="voyage-media-align">
                <img src="https://i.discogs.com/1pfWOq9PLZlhgHWipY4dcKuFEh-0JQiSrG8Fvo79j60/rs:fit/g:sm/q:40/h:300/w:300/czM6Ly9kaXNjb2dz/LWRhdGFiYXNlLWlt/YWdlcy9SLTEyMTM3/MTI2LTE1MjkwNDM2/MTMtMzQ4NS5wbmc.jpeg" class="voyage-image">
                <p>caption</p>
            </div>
        </div>
        <div class="voyage-media-container">
            <div class="voyage-media-align">
                <video controls="controls" class="voyage-video">
                    <source src="video1.mp4">
                </video>
                <p>caption</p>
            </div>
        </div>
    </div>
</div>

In here I have add another class to the third div and set its z-index to 1.

Thanks and best regards!

[FIXED] How can I place a embedded video on-top of an image in HTML/CSS?

Issue

So I'm trying to create a simple layering technique, by putting an image behind a video in html/css. To give the video section some meaning and background style.

Heres a photoshop mockup of what I'm trying to achieve.

http://s8.postimg.org/tl749vxvp/example.jpg

HTML

 div id= "background">
 img src="images/imgc.jpg" class="stretch" alt="image"
 *Video embedding goes here*   

CSS

.stretch {
    width : 100%;
    height: auto;%;
}

#background {
    position: relative ;
}

#wrapper {
   background-size: 100% auto;
}

Solution

You need to center the video player div over the image(or preferably, a div with a background image). Here's some html:

<html>
    <head>
        <!-- Flowplayer js and css -->
    </head>
    <body>
        <div style="width:100%; height:100%; background-image:url('path/to/your/image.png');">
            <div id="player" style="width:600px; height:400px; position:absolute; left:50%; margin-left:-300px; top:50%; margin-top:-200px"></div>
        </div>
    </body>
</html>

Note: that this css:

width:600px;
height:400px;
position:absolute;
left:50%;
margin-left:-300px;
top:50%;
margin-top:-200px

makes a div of 600px x 400px and centers it within the parent div. If you need to change the height to 800px for example, change margin-top to 1/2 of the amount, in this case -400px

I should mention that there are various css options for the background image of the main div, read about them here: http://www.w3schools.com/cssref/css3_pr_background.asp. You may want to look at background-size:contain

After you have the div centered over the image as desired, just follow the instructions here (http://flash.flowplayer.org/documentation/installation/index.html) to get your video playing with flowplayer.

[FIXED] How do I hide related videos at the end of a YouTube playlist embed code?

Issue

I am using this code to embed a playlist:

<iframe width="816" height="459"     
  src="https://www.youtube.com/embed/videoseries?list=xxx" 
  frameborder="0" allowfullscreen="">

To hide the related videos, normally I add ?rel=0 (that's in the case of a single video embed), but if I try it here:

<iframe width="816" height="459" src="https://www.youtube.com/embed/videoseries?list=PL4Zkb_7gMrOzZlVy7jIeCjwScavYp6ssm?rel=0" 
 frameborder="0" allowfullscreen="">
 </iframe>

I get the "bad video" fuzzy YouTube screen (sorry, I don't know the technical term for this)!

There is no "hide related" option in the YouTube "SHOW MORE" settings for the playlist.

Solution

You have to use the '&' when adding more parameters to the url. Update the src field with following.

"https://www.youtube.com/embed/videoseries?list=PL4Zkb_7gMrOzZlVy7jIeCjwScavYp6ssm&rel=0"

[FIXED] Facebook Graph API: How can I retrieve the number of views of a video I shared from another profile using the Facebook Graph API?

Issue

I have a business manager account for my Facebook profile and I re-shared a video from another profile. How can I retrieve the number of views that my re-share accounted for through the Facebook Graph API?

If the video were posted directly to my profile rather than re-shared, I'd be able to use the /v2.8/{video-id}/video_insights method to retrieve the video stats, but that does not appear to be available for re-shares. The only insights that I can find for re-shares appears to be /v2.8/{post-id}/insights, but that does not include video views.

For example, here is a Facebook post by The Dodo where they are re-sharing a video by Discovery News.

Solution

This information can be retrieved by making a call to /v2.8/{post-id}/insights/post_video_views

[FIXED] Decent Video Chat API?

Issue

Just wondering. I'm looking to build a small web application with a single page. It will essentially be a video chat page so I'm looking for an API I can use or any other solutions?

This would be run on a LAMP stack.

Solution

A SO search reveals lots of similar questions which are worth checking/contributing to.

It depends if you want something free or are prepared to pay but some things that come up are (mind I havent used any of these myself):

• http://www.tokbox.com/
• http://code.google.com/apis/talk/open_communications.html#developer
• http://www.process-one.net/en/blogs/article/oneteam_media_server_by_processone
• https://sites.google.com/site/webrtc/ (Now at: https://webrtc.org/ )
• https://www.skype.com/en/developer/
• http://farsight.freedesktop.org/wiki/
• https://www.twilio.com/docs/api/video
• Some MS libraries are mentioned here: Developing a Video Chat Application with high quality video streaming
• Apple had promised to open up FaceTime but so far nothing has happened

To get up and running quickly it seems tokbox would be most suitable.
