  • configure.ac : Erase default -O2 when setting -O3.

    27 juillet 2014, par Erik de Castro Lopo
    configure.ac : Erase default -O2 when setting -O3.

    Previously CFLAGS had a -O3 at the start and a -O2 at the end. According
    
to the GCC docs :
    

        https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/Optimize-Options.html
    

        "If you use multiple -O options, with or without level numbers,
    
    the last such option is the one that is effective" which means that
    
    GCC doesn’t try to use SIMD to vectorize the code, etc."

  • broadcast HLS/TS Stream from FFMPEG

    2 août 2014, par Dylan Lundy

    I’m still wrapping my head around most of this, so sorry if my issue is an obvious one !

    I’m trying to broadcast a FFMPEG ’stream’ to a HLS stream i can load into a webpage.

    My understanding is that i need a media server to broadcast it from FFMPEG to a HLS stream ? with FFMPEG feeding the data to the server. I’m probably wrong though.

    I previously semi achieved what i want to do with stream-m, however it was too slow (less than 1 FPS) and wasn’t broadcasting in HLS.

    Previously, the steps i went through were to launch the stream-m server. then launce FFMPEG with the following command :

    ffmpeg.exe -f dshow -i video="screen-capture-recorder" -r 1 -g 2 -vcodec libvpx -vb 1024 -f matroska http://localhost:8080/publish/first?password=secret

    I could connect to the stream with Chrome using the following HTML :

    <video src="http://localhost/consume" autoplay="autoplay">
    
</video>

    The issue is that this was slow, unusable in fact, and it’s not in HLS/H264.

    I need the feed in the specific codec as i intend to send it to a WiiU browser, which only supports "M3U8+TS(HTTPLiveStreaming)"

  • FFmpeg Get the previous 30 seconds of m3u8 stream

    17 novembre 2019, par Garret Harp

    I currently am trying to use an m3u8 file of a live stream to get the previous 30 seconds of what happened and save it to an mp4 file, basically a clip of the last 30 seconds of the live stream.

    I am currently running the following FFmpeg command : ffmpeg -live_start_index 0 -i source.m3u8 -c copy -ss 30 -t 30 output.mp4

    Rather than getting the previous 30 seconds of what happened on the stream, it gets 30 seconds of the stream once the command is run.

    Does anyone know how I could change this so go back 30 seconds in the stream to save over what previously happened ?
