  • FFmpeg - downmixing FLAC 6.1 to AAC 5.1

    7 juillet 2014, par Martijn

    I can’t seem to figure out how to do this. I’ve been staring at these commands :
    https://trac.ffmpeg.org/wiki/AudioChannelManipulation

    But to no avail. It’s a tad above my level, sadly. Here’s the ffmpeg -i output for the video in question :

    As you can see, one of the streams is a FLAC 6.1 stream. I wanted to convert that to AAC, and I know how to do that, basically like this :

    ffmpeg -i "input.mkv" -codec:v copy -codec:a aac -strict -2 -b:a 320k -f matroska "output.mkv"

    But apparently AAC doesn’t support 6.1 audio :

    ...
    
[aac @ 03b26860] Unsupported number of channels: 7
    
Output #0, matroska, to 'd:\Movies\[Coalgirls]_Spirited_Away_(1920x1038_Blu-ray_FLAC)_[92372194].aac.mkv':
    
    Stream #0:0(jpn): Video: h264, yuv420p10le, 1920x1038 [SAR 1:1 DAR 320:173], q=2-31, 23.98 fps, 90k tbn, 1k tbc (default)
    
    Stream #0:1(jpn): Audio: aac, 0 channels, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 aac
    
    Stream #0:2(eng): Subtitle: ssa, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 ssa
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (copy)
    
  Stream #0:1 -> #0:1 (flac (native) -> aac (aac))
    
  Stream #0:9 -> #0:2 (ssa (native) -> ssa (native))
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    That’s fine, so I wanted to downmix it to 5.1 and encode as AAC. But I can’t seem to work out how to. Any advice ?

  • Android ExoPlayer stream mp3 over HTTP

    8 juillet 2016, par kevintcoughlin

    I’m trying to get a grasp on the new ExoPlayer library introduced this year at Google I/O 2014 so that I can incorporate it into my application.

    I’m attempting to stream an mp3 over HTTP, but so far have been unsuccessful. I’m not sure if it’s possible, but I’m trying to accomplish this without extending any of the base Source/Sample classes. My code is as follows :

    In my Activity

    SampleSource s = new FrameworkSampleSource(this, Uri.parse("http://traffic.libsyn.com/joeroganexp/p518.mp3"), null, 1);
    

    
// Since I only have 1 audio renderer
    
ExoPlayer player = ExoPlayer.Factory.newInstance(1);
    

    
MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(s);
    
player.prepare(audioRenderer);
    
player.setPlayWhenReady(true);

    To my untrained eye it seems like I can get the TrackInfo correctly, but am having a problem reading the data over HTTP. It also seems that how the framework sniffs the mimetype is failing even though I do receive type ’audio/mpeg’.

    Again, I appreciate any direction I receive. I realize that these APIs are very new.

    Thanks !

  • Video Conversion to have Play Speed

    24 juin 2014, par Taufiq

    There is a open source Media Player Component called Media Kit (https://wpfmediakit.codeplex.com/). It supports Play Speed. But its dependent on video format.

    I have generated a video using SharpAvi (http://sharpavi.codeplex.com/) sample project, using Motion Jepg Encoder.

    This video does not have Play Speed support for some reason. Details Below from ffmpeg

    Video: mjpeg (MJPG / 0x47504A4D), yuvj420p(pc), 1920x1080 [SAR 96:96 DAR 16:9], 9818 kb/s, 10 fps, 10 tbr, 10 tbn, 10 tbc

    Next I download an flv video from Youtube and Media Kit’s play speed works fine with this video.

    Video: flv1, yuv420p, 426x240, 259 kb/s, 23.98 fps, 23.98 tbr, 1k tbn, 1k tbc

    Now I converted them into common MP4 format using ffmepg

    ffmpeg -i "1.avi" -ar 22050 -b 2048k "1.mp4"
    
ffmpeg -i "2.flv" -ar 22050 -b 2048k "2.mp4"

    Results

    1.mp4

     Video: h264 (High) (avc1 / 0x31637661), yuv420p, 426x240, 1235 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)

    2.mp4

    Video: h264 (High) (avc1 / 0x31637661), yuvj420p(pc), 1920 x1080 [SAR 1:1 DAR 16:9], 158 kb/s, 10 fps, 10 tbr, 10240 tbn, 20 tbc (default)

    The thing is the converted video from flv file still supports play speed where else the converted mp4 from the Avi does not. What is that I am missing

    More Details Below.
