  • ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]

    14 novembre 2024, par danielRICADO

    using ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8

    


    std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
                         " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
                         " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
                         " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
                         ts_file_pattern + " -f hls " + m3u8_file;


    


    I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available

    


    bool is_h264_v4l2m2m_available() {
    std::string result = exec_command("ffmpeg -encoders 2>&1");
    return result.find("h264_v4l2m2m") != std::string::npos;
}


    


    if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.

    


    other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

  • libavcodec.so.58 not found when running software compiled with opencv

    22 avril, par Abinaya

    I am using ubuntu 22.04. Now every time I try to run software compiled with Opencv, I get the following error :

    


    `libavcodec.so.58 => not found
 libavformat.so.58 => not found
 libavutil.so.56 => not found
 libswscale.so.5 => not found
`


    


    Looking around /lib/x86_64-linux-gnu/, I can find libavcodec.so.59, but not libavcodec.so.58.

    


    When trying to run sudo apt-get install libavcodec58, I get :

    


    Package 'libavcodec58' has no installation candidate

    


    I've scoured the internet in search of an answer, but could not find anything at this point. Any help with solving this problem will be very much appreciated.

    


    I have tried to recreate symbolic link with
'ls -l libavcodec.so.59'
1 root root 23 Aug 10 2024 libavcodec.so.59 ->libavcodec.so.59.37.100`

    


    'dconfig -vl libavcodec.so.59.37.100'
libavcodec.so.59 -> libavcodec.so.59.37.100`

    


    But I am still struck
