  • FFmpeg live streaming for media source extensions(MSE)

    1er septembre 2022, par IceCreamVan

    I try implement video live streaming from RTSP stream to webpage with media source extensions(MSE) with using FFmpeg

    


    Expected system diagram.

    


    enter image description here

    


    I know that this task can realize with HLS or WebRTC, but HLS have large delay and WebRTC very hard to implementation.

    


    I want catch RTSP stream with FFMPEG split it to ISO BMMF(ISO/IEC 14496-12) chuncks in "live mode" and send it to my web server by TCP in which i restream this chunks to webpage by websocket. In webpage i append chunck to buffer sourceBuffer.appendBuffer(new Uint8Array(chunck)) and video play in streaming mode.

    


    Problem in first step with ffmpeg i can easy split RTSP stream to segments with this

    


    ffmpeg -i test.mp4 -map 0 -c copy -f segment -segment_time 2 -reset_timestamps 1 output_%03d.mp4


    


    but i cant redirect output to tcp ://127.0.0.1 or pipe:1, if i correctly understood segment not work with pipes. For example i can easy send video frames in jpg by TCP with image2 catch ff d9 bytes in TCP stream and split stream to jpg images.

    


    ffmpeg -i rtsp://127.0.0.1:8554 -f image2pipe tcp://127.0.0.1:7400


    


    How i can split RTSP stream to ISO BMMF chunks for sending to webpage for playing with media source extensions ? Or other way to prepare RTSP stream with FFmpeg for playing in MSE. Maybe i not correctly understood how working MSE and how prepare video for playing.

    


  • checkasm : arm : preserve the stack alignment in x264_checkasm_checked_call

    checkasm : arm : preserve the stack alignment in x264_checkasm_checked_call

    The stack used by x264_checkasm_checked_call_neon was a multiple of 4
    
when the checked function is called. AAPCS requires a double word (8 byte)
    
aligned stack public interfaces. Since both calls are public interfaces
    
the stack is misaligned when the checked is called.
    

    This can cause issues if code called within this (which includes
    
the C implementations) relies on the stack alignment.

  • How can start a process and stop the process if "error" string appear in the console output strings in one line commands set

    25 janvier 2018, par Thm Lee

    Now I want one line cmd commands set which start a process and monitor the consol output strings stream. And so if error message appear in the process’s console output, then could stop the process immediately.

    For example, I tried below commends sets, but failed. It seems find command didn’t get any strings streams in which search key word "error"

    ffmpeg "endcoding process options set" | find "error" && exit

    or,

    ffmpeg "endcoding process options set" 2>&1 find "error" && exit

    Is there any solutions about this ?

    Thanks in advance
