Issue created Jun 03, 2020 by Edward Hervey@bilboed🤘Owner

nvenc h264 with interlaced content

To reproduce : gst-validate-launcher -t validate.file.transcode.to_mp3_and_h264_in_mp4.GH1_00094_1920x1280_MTS

The problem is essentially that when being provided interlaced content, nvh264enc outputs the following in the first buffer:

  • AU
  • SPS
  • PPS
  • Slice IDR
  • AU
  • AU
  • Slice

And h264parse outputs this as two buffers:

  • AU / SPS / PPS / Slice IDR
  • AU / Slice

And qtmux complains, because the 2nd buffer doesn't have a PTS.

I'm still not sure who's at fault here:

  1. nvench264 is outputting stray AU, the first buffer should have : AU / SPS / PPS/ Slice IDR / Slice
  2. h264parse should not split the buffer in two ? See #101
  3. qtmux should store the two different fields

Suggestions/feedback welcome
