• MP4 videos created with AVMutableComposition and AVAssetExportSession work in Quicktime, but appear corrupted in all other video tools

  20 mai 2020, par James Porter

  I'm trying to edit segments of multiple movies together into one clip using Swift, AVFoundation, and AVKit on macOS. The following Swift code is a good example of what I'm trying to do :

  



  import AVFoundation
import AVKit

let source1 = AVAsset(url: URL(string: "https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4")!)
let source2 = AVAsset(url: URL(string: "http://techslides.com/demos/sample-videos/small.mp4")!)

let comp = AVMutableComposition()

comp.addMutableTrack(withMediaType: .video, preferredTrackID: kCMPersistentTrackID_Invalid)
comp.addMutableTrack(withMediaType: .audio, preferredTrackID: kCMPersistentTrackID_Invalid)

func cmtime(_ i: Double) -> CMTime {
    return CMTime(seconds: i, preferredTimescale: 600)
}

func insertSecond(into: AVMutableComposition, from: AVAsset, start: CMTime, at: CMTime) throws {
    let videoTrack = into.tracks(withMediaType: .video).first!
    let audioTrack = into.tracks(withMediaType: .audio).first!
    try videoTrack.insertTimeRange(
        CMTimeRange(start: start , duration: cmtime(1.0)),
        of: from.tracks(withMediaType: .video).first!,
        at: at
    )
    try audioTrack.insertTimeRange(
        CMTimeRange(start: start, duration: cmtime(1.0)),
        of: from.tracks(withMediaType: .audio).first!,
        at: at
    )
}

try insertSecond(into: comp, from: source1, start: cmtime(3.0), at: cmtime(0.0))
try insertSecond(into: comp, from: source2, start: cmtime(2.0), at: cmtime(1.0))
try insertSecond(into: comp, from: source1, start: cmtime(100.0), at: cmtime(2.0))
try insertSecond(into: comp, from: source2, start: cmtime(3.0), at: cmtime(3.0))
try insertSecond(into: comp, from: source1, start: cmtime(350.0), at: cmtime(4.0))


if let sess = AVAssetExportSession(asset: comp, presetName: "AVAssetExportPresetHighestQuality") {
    sess.outputURL = URL(fileURLWithPath: "/tmp/output.mp4")
    sess.outputFileType = .mp4
    sess.exportAsynchronously {
        print("done")
        print(sess.error ?? "success")
    }
}


  



  Running this code does produce an output.mp4 file successfully, and that file can be played in Quicktime with no problems. You should be able to paste the above code into a Playground to reproduce the video (the source videos are all publicly available sample videos hosted on the web). I've also uploaded it to S3 here, so you can download and analyze it without having to run the code yourself.

  



  However, attempting to open or process it with any other video software results in errors.

  



  VLC will attempt to play the file, but has a very difficult time with it. The video freezes a lot, desyncs with the audio, includes frames that Quicktime doesn't show at all, and skips some sections entirely.

  



  Firefox will also attempt to play with file, but clearly can't decode it properly and has glitchy video output. Chrome freezes after the first second of playback.

  



  I tried diagnosing further using ffprobe and ffmpeg.

  



  Running ffprobe -show_frames output.mp4 1>/dev/null shows :

  Attempting to transcode to another format with ffmpeg (ffmpeg -i output.mp4 output.avi) has a lot of warnings and errors :

  The code above is just one example, I've seen similar problems with varying degrees of severity in lots of variations on this code. I've tried many things, including :

  



  

  • using local file URLs rather than HTTPS urls

  


  • using .mov rather than .mp4 files

  


  • using AVMovie and AVMutableMovie (and various setting tweaks, e.g. setting AVURLAssetPreferPreciseDurationAndTimingKey to true) rather than AVMutableComposition

  


  • tweaking settings (presets, etc.) on the AVAssetExportSession

  


  • constructing CMTime objects in different ways

  


  



  but to no avail—I can't seem to get AVFoundation to produce a video file that other tools can process.

  



  Any help is appreciated, even just any thoughts on what's unusual about the encoding of the output file, which you can download here if you can't or don't want to run the above Swift code to reproduce it yourself.

  


• Android YouTube Live v3 rtmp streaming via ffmpeg won't show preview

  14 décembre 2017, par Ariel Yust

  Hi everyone I’m breaking my head over this issue here,
  I’m developing an Android App for streaming content from the user’s device camera (back/front) to a live streaming on YouTube.

  Problem :
  YouTube Live shows "The health is good." in (Live Streaming->Events) but there’s nothing showing in the preview... in fact when I press play it tells me "An error has occurred, please try again later".

  Why is this happening ? what could be the problem ?

  What I’m doing :
  using google’s Oauth 2.0 and google api for login.
  YouTube V3 data api’s for creating a new broadcast and stream or use an opened stream - I’m using RTMP.

  I’m opening Camera Api1 and capturing the video into a SurfaceTexture, then I encode images and audio (MIC) using Android’s MediaCodec, save a 3+- seconds *.mp4 file locally and then once the muxer is done I stream the file with ffpmeg.

  String[] cmd = {
  
              "-i", filePath, //local file path (video is playable with vlc)
  
              "-strict", "experimental",
  
              "-acodec", "aac",
  
              "-ac", "1",
  
              "-ar", "44100",
  
              "-vcodec", "libx264",
  
              "-pix_fmt", "yuv420p",
  
              "-r", "30",
  
              "-g", "60",
  
              "-vb", "512k",
  
              "-profile:v", "main",
  
              "-preset", "medium",
  
              "-f", "flv",
  
              "-s", "1280x720",
  
              CreateBroadcast.rtmpUrl
  
          };
  
  
  
  ffmpeg.execute(cmd, responseHandler); //responseHandler notify me to send next file
  
  
  
  //how I set a new rtmpUrl, in CreateBroadcast.java
  
  rtmpUrl = 
  
      returnedStream.getCdn().getIngestionInfo().getIngestionAddress() +
  
      File.separator + 
  
      returnedStream.getCdn().getIngestionInfo().getStreamName();

• avio_open2 fails randomly for RTMPS Facebook live streaming

  3 janvier, par Usama

  I am trying to re stream a video to Facebook RTMPS endpoint and , facing an issue specifically with Facebook's RTMPS endpoint . I have tried with linkedin RTMPS endpoint and its working fine , but Facebook end point some times works and fails some times its totally random . The avio_open2 call sometimes fails randomly, returning a -5 error. This only seems to happen with the Facebook endpoint .on ffmpeg log side I see that the handshake was successful , I don't understand the reason for failure here. (i am running in multithreaded environment )

  


  int ret = avformat.avio_open2(pb, url , AVIO_FLAG_WRITE, null, getOptionDictionary()) ;
