Description

When using NVENC (h264_nvenc) as hardware encoder for H.264, if the input file has Closed Captions attached to the frame data as side data then the resulting video does not have thos closed captions.

I attached the patch for nvenc.c file from FFmpeg 3.4.

Duplicate of ticket #6726, a patch was apparently already suggested.

The issue with #6726 is that the apparently suggested patch was never applied.

Perhaps this ticket should remain open until the issue is solved?
