  • avformat/dashenc : Remove muxer overhead from Bandwidth field in DASH manifest

    4 septembre 2018, par Karthick Jeyapal
    avformat/dashenc : Remove muxer overhead from Bandwidth field in DASH manifest

    Fixes bug id #7386
    
Muxer overhead calculations was intented for HLS playlist as Apple's mediastreamvalidator tests were failing.
    
But applying the same fix for DASH manifest proved counterproductive, as Bandwidth can be used for segment name templates.

    Upload video and convert to MPEG-DASH I’m doing ...

    Upload file
    
1. move_uploaded_file($_FILES['video']['tmp_name'], video.mp4);
    

    
Converting video
    
2.  ffmpeg -i video.mp4 -ac 2 -ab 128k -c:v libx264 -preset veryfast -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 3000k -maxrate 3000k -bufsize 1500k -vf "scale=-1:1080" video_1080.mp4
    
    ffmpeg -i video.mp4 -ac 2 -ab 128k -c:v libx264 -preset veryfast -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720"  video_720.mp4
    
    ffmpeg -i video.mp4 -ac 2 -ab 128k -c:v libx264 -preset veryfast -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 500k  -maxrate 500k  -bufsize 500k  -vf "scale=-1:480"  video_480.mp4
    

    
From mp4 to MPEG-DASH
    
3. MP4Box -dash 4000 -frag 4000 -rap -segment-name %s/segment_ -url-template -out manifest.mpd video_1080.mp4 video_720.mp4 video_480.mp4
    

    
Delete mp4 videos
    
4.  unlink('video_1080.mp4');
    
    unlink('video_720.mp4');
    
    unlink('video_480.mp4');

    Everything is working. But I’m not sure that this is the right decision. Is there a better solution ? Do I do everything right ?

  • Android convert exo to mp4 after download dash

    7 août 2018, par Ali

    I have downloaded a Dynamic Adaptive Streaming over HTTP (DASH) via android DashDownloader class that is provided by exo player.

    SimpleCache cache = new SimpleCache(file.getAbsoluteFile(), new NoOpCacheEvictor());
    
DefaultHttpDataSourceFactory factory = new DefaultHttpDataSourceFactory("ExoPlayer", null);
    
DownloaderConstructorHelper constructorHelper = new DownloaderConstructorHelper(cache, factory);
    

    
// Create a downloader for the first representation of the first adaptation set of the first
    
// period.
    
DashDownloader dashDownloader = new DashDownloader(Uri.parse(url), Collections.singletonList(new RepresentationKey(0, 0, 0)), constructorHelper);
    
dashDownloader.download();

    Above code save many chunk .exo files into provided directory, How can i convert this files to single mp4 file ?
