  • Live streaming dash content using mp4box

    15 mai 2017, par galbarm

    I’m trying to live stream H.264 content to HTML5 using the media source extensions API.

    The following method works pretty well :

    ffmpeg -i rtsp://10.50.1.29/media/video1 -vcodec copy -f mp4 -reset_timestamps 1 -movflags frag_keyframe+empty_moov -loglevel quiet out.mp4

    and then :
    mp4box -dash 1000 -frag 1000 -frag-rap out.mp4

    I can take the MP4Box output (out_dashinit.mp4) and send it through Web Sockets, chunk by chunk, to a JavaScript client that feeds it to the media source API.

    However, this is not a good method for live content.

    What I’m trying to do now, is to create a single pipeline in order to do it in realtime and with the minimum possible latency.
    With FFmpeg it’s possible to redirect the output to stdout instead of out.mp4 and grab the content.
    I couldn’t figure out if it’s possible to combine MP4Box into the pipeline.

    1. Can MP4Box take the input data from a source which is not a file ?
    2. Can MP4Box grab such a content progressively (either from a file or other source) while it is arriving in realtime ? i.e. wait a little if stream stops for 1 sec and resume automatically.
    3. Same question but for the output : can it output to something which is not a file (such as stdout) and can it do so progressively so that whenever output data is ready, I will be able to take it and transfer it to the web client, essentially generating a never-ending dashed MP4.

  • ffmpeg, live MPEG-TS demux & decode

    8 mai 2017, par NadavRub

    Environment

    • Ubuntu-14
    • C++
    • ffmpeg

    Use-case

    • Live SPTS is received via UDP by a 3rd party module
    • TS Packets are received iteratively
    • The TS Video (ES) should be decoded in minimal latency

    Considered Implementation

    • Upon TS packet reception, immediately push it to the TS demux
    • Once enough packets are received the video format is resolvable, create the video codec
    • Push each video packet into the video decoder
    • Once enough video packets were processed the video codec result a valid output frame

    Problem at-hand

    Can this be done w/ ffmpeg ?!?!, … using “avformat_open_input” mandate a file to read from… I need a way where I can iteratively push packets to the TS demuxer ( w/ minimal latency )…

    Does ffmpeg support the above mentioned use-case ? How ?
