  • FFmpeg retrieve a specific program from TS file

    8 mai 2017, par chang jc

    I tried to retrieve a specific program from a TS file.
    Said :

    Then I tried to retrieve a specific program as :

    ffmpeg -i INPUT -map 0:p:1344 OUTPUT

    It succeeds greatly but the only thing I noticed is :

    it seems to apply transcode (decode & encode again) to the output implicitely ?

    If so, could I avoid the transcoding by command ? Or it is a necessary ?
    It it is a need, WHY ?

  • avfilter/vf_bwdif : Add a filter_line3 method for optimisation

    avfilter/vf_bwdif : Add a filter_line3 method for optimisation

    Add an optional filter_line3 to the available optimisations.
    

    filter_line3 is equivalent to filter_line, memcpy, filter_line
    

    filter_line shares quite a number of loads and some calculations in
    
common with its next iteration and testing shows that using aarch64
    
neon filter_line3s performance is 30% better than two filter_lines
    
and a memcpy.
    

    Adds a test for vf_bwdif filter_line3 to checkasm
    

    Rounds job start lines down to a multiple of 4. This means that if
    
filter_line3 exists then filter_line will not sometimes be called
    
once at the end of a slice depending on thread count. The final slice
    
may do up to 3 extra lines but filter_edge is faster than filter_line
    
so it is unlikely to create any noticable thread load variation.

  • Stream H264 raw data on RTSP server

    1er janvier, par Aitazaz

    I have H264 hex string data saved in a list.&#xA;The data is in correct format as it is being received, I am trying to stream it to RTSP server.

    &#xA;

    I have stream the data in realtime as it is from a dashcam.

    &#xA;

    The RTSP server is deployed but when I stream frames to it, the connection is created and then ends in an instant (does not last for a second)

    &#xA;

    The code is mentioned below which performs this streaming task.

    &#xA;

    def h264_stream_to_rtsp(data_list, rtsp_url):&#xA;    try:&#xA;        ffmpeg_command = [&#xA;            "ffmpeg", &#xA;            "-f", "h264",&#xA;            "-i", "-",&#xA;            "-vcodec", "libx264",&#xA;            "-preset", "fast",&#xA;            "-f", "rtsp",&#xA;            "-analyzeduration", "5000000",&#xA;            "-probesize", "5000000", &#xA;            rtsp_url  # The RTSP URL to stream to&#xA;        ]&#xA;        &#xA;        ffmpeg_process = subprocess.Popen(ffmpeg_command, stdin=subprocess.PIPE)&#xA;&#xA;        for index, hex_data in enumerate(data_list):&#xA;            # print(f"Processing hex data {index &#x2B; 1}/{len(data_list)}...")&#xA;&#xA;            if len(hex_data) % 2 != 0:&#xA;                hex_data = &#x27;0&#x27; &#x2B; hex_data  # Append a leading zero if length is odd&#xA;&#xA;            binary_data = binascii.unhexlify(hex_data)&#xA;&#xA;            ffmpeg_process.stdin.write(binary_data)&#xA;&#xA;        ffmpeg_process.stdin.close()&#xA;&#xA;        ffmpeg_process.wait()&#xA;        print("Stream completed.")&#xA;&#xA;    except KeyboardInterrupt:&#xA;        print("Stopping live stream.")&#xA;    except Exception as e:&#xA;        print(f"Error: {e}")&#xA;

    &#xA;

    Logs from the RTSP server are mentioned below :

    &#xA;

    How can I stream continuously ?
