Handle yuv420p(tv, bt2020nc/bt2020/arib-std-b67, progressive) properly

Pipeline crashes when video has such properties. Resetting them with FFmpeg fixes the operation:

```
ffmpeg -i in.mp4 -map 0:v:0 -map 0:a? \
  -c:v copy \
  -bsf:v "h264_metadata=video_full_range_flag=0:colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1" \
  -c:a copy \
  out_bt709.mp4
```
