  • Restreaming video containing two languages live with ffmpeg

    9 novembre 2012, par user1810837

    I have a project where i need to restream a live stream which has two languages setup on the audio.
    Spanish on left and English on right

    The stream mapping is :

    Stream #0:0: Video: h264 ([7][0][0][0] / 0x0007), yuv420p, 512x288 [SAR 1:1 DAR 16:9], q=2-31, 1k tbn, 1k tbc
    
Stream #0:1: Audio: mp3 ([2][0][0][0] / 0x0002), 44100 Hz, stereo, s16, 18 kb/s

    I need to restream this back live with just the English from the right side or just spanish from the left side, I tried looking everywhere but did not find any type of solution .

    Since this needs to be done live, I can't be using other programs to separate video and audio to get it done.

    This needs to be done through ffmpeg and I wonder if it even capable of doing so with original built or it would need some custom modification.
