  1. I want to convert an *.mp4 video with AVC H.264 and AAC to an *.AVI video with same video condec but MP3 audio.

    Therefore I issued the following command:

    ffmpeg -i test.mp4 -acodec libmp3lame -aq 6 -c:v copy -bsf h264_mp4toannexb target.mp4

    and got the following error:

    [AVBSFContext @ 00000000004502e0] Codec 'mp3' (86017) is not supported by the bitstream filter 'h264_mp4toannexb'. Supported codecs are: h264 (28)
    Error initializing bitstream filter: h264_mp4toannexb
    Error initializing output stream 0:1 --
    Conversion failed!


    Why?

    Is "h264_mp4toannexb" meanwhile replaced by simple "h264" parameter?

    How else can I achieve the conversion?

  2. -bsf:v h264_mp4toannexb

    (I don't know if necessary for avc-in-avi. But avc-in-avi is usually not recommended in the first place ...)
