  • sdp : Simplify parsing/conversion of H264 extradata

    3 octobre 2014, par Martin Storsjö
    sdp : Simplify parsing/conversion of H264 extradata

    By using ff_avc_write_annexb_extradata instead of the h264_mp4toannexb
    
BSF, the code for doing the conversion itself is kept much shorter,
    
there’s less state to restore at the end, we don’t risk leaving the
    
AVCodecContext in an inconsistent state if returning early due to
    
errors, etc.
    

    Also add a missing free if the base64 encoding fails.

  • NodeJS piping with ffmpeg

    8 février 2014, par Gnap

    I wanted to do a HTTP live stream on a screen cast with using ffmpeg, nodejs and html5 . I wanted it to be as real time as possible. However, I find that my video received by the client was behind by 1 2 seconds (On Chrome/Chromium). I am using vp8/webm as my codec.

    I have eliminated the following factors as such :
    1) Network : I have tried serving and receiving the video file locally by stating the video source to be 127.0.0.1:PORT or localhost:PORT
    2) ffmpeg encoding speed:I have tried outputting the file locally, it the "delay" seems to be negligible.
    3) Chrome internal buffer. The buffer was accounted to be 0.07s 0.08s.

    On the nodeJS side, I have a child process that runs the ffmpeg command, and did a ffmpeg.stdout.pipe(res) ; <— ffmpeg is child_process.spawn(...)

    So it seems that the ffmpeg.std.pipe(res) of nodejs seems to be the one delaying the video stream. Am I correct in assuming so ? Is there anyway that I may reduce the delay ?

    hlsenc : Use AV_TIME_BASE units for all the computations

    Do not risk mixing different timebases.
