  • ffmpeg Live Smooth Streaming multi track audio to Azure Media Services

    11 décembre 2022, par Jean P

    Does anyone has a working example on how to ffmpeg stream audio from multiple sound cards using ISMV to Azure Media Services ? This should generate multi track audio on a player.

    


    Appreciate any help.

    


    I have tried many many examples with no success...

  • How do I configure ffmpeg & openh264 so that the video file can be opened in Windows Media Player 12

    10 mars 2017, par Sacha Guyer

    I have successfully created h264/mp4 movie files with ffmpeg and the x264 library.

    Now I would like to change the h264 library from x264 to openH264. I could replace the x264 library with openH264, recompile ffmpeg and produce movie files, without changing my sources that produce the movie. The resulting movie opens fine in Quicktime on Mac, but on Windows, Windows Media Player 12 cannot play it.

    The documentation about Windows Media Player support for h264 is unclear. File types supported by Windows Media Player states in the table that Windows Media Player 12 supports mp4, but the text below says :

    Windows Media Player does not support the playback of the .mp4 file format.

    From what I have observed, Windows Media Player 12 IS capable of playing h264/mp4 files, but only when created with x264.

    Does anyone know how I need to adjust the configuration of the codec/context so that the movie plays in Windows Media Player ? Does Windows Media Player only support certain h264 profiles ?

    I noticed the warning :

    [libopenh264 @ 0x...] [OpenH264] this = 0x..., Warning:bEnableFrameSkip = 0,bitrate can’t be controlled for RC_QUALITY_MODE,RC_BITRATE_MODE and RC_TIMESTAMP_MODE without enabling skip frame

    With the configuration :

    av_dict_set(&options, "allow_skip_frames", "1", 0);

    I could get rid of this warning, but the movie still does not play. Are there other options that need to be set so that the movie plays in Windows Media Player ?

    Thank you for your help
