  FFmpeg - generate x264 CBR video transport stream with C-API - ZeroDefect Newest 'libx264' Questions - Stack Overflow
  Using various posts sprinkled around the Internet, including this one here on SO, I've been able to understand how to use the FFmpeg cli to generate a CBR video bitrate using the x264 codec (wrapped in an MPEG-2 transport stream).

  x264 encoded frames into a mp4 container with ffmpeg API - PJD Newest 'libx264' Questions - Stack Overflow
  I'm struggling with understanding what is and what is not needed in getting my already encoded x264 frames into a video container file using ffmpeg's libavformat API. My current program will get the x264 frames like this - while( x264_encoder_delayed_frames( h ) ) printf("Writing delayed frame %u\\n", delayed_frame_counter++); i_frame_size = x264_encoder_encode( h, &nal, &i_nal, NULL, &pic_out ); if( i_frame_size p_payload, i_frame_size, 1, video_file_ptr) ) printf("Failed to write a delayed x264 frame.\\n");  (...)
