feat(ffmpeg): support ffmpeg env args and hw codecs

Browse source 
Parse FFMPEG_ARGS and FFMPEG_OUTPUT_ARGS into arrays
  Detect 'qsv' and 'cuda' flags and map codecs to
  Hardware encoders (h264_qsv/hevc_qsv and h264_nvenc/hevc_nvenc)
  Make codec_short mutable to allow reassignment
  Log constructed ffmpeg command for visibility
  Enables runtime custom ffmpeg args and hw encoder selection
  Improves deployment flexibility and performance tuning
