• 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
