Summary of the bug:
After commit 99e2af4
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/99e2af4e7837ca09b97d93a562dc12947179fc48
I have frame jerking with vdr-plugin-softhddevice and vdr-plugin-
softhdcuvid.(https://github.com/ua0lnj/vdr-plugin-softhddevice,
https://github.com/jojo61/vdr-plugin-softhdcuvid), with interlaced video
and cuvid deinterlace bob or adaptive. No errors in libavcodec debug log.
But ffplay works without problems: DISPLAY=:0 ffplay -x 1920 -y 1080
-vcodec h264_cuvid -deint 2 -drop_second_field 0 -v debug ./00001.ts
The only difference i found in the logs:
ffplay:
[h264_cuvid @ 0x7139edffb2c0] Format nv12 chosen by get_format().
[h264_cuvid @ 0x7139edffb2c0] Formats: Original: nv12 | HW: nv12 | SW:
nv12
softhddevice:
[h264_cuvid @ 0x7a36343b0900] Format cuda chosen by get_format().
[h264_cuvid @ 0x7a36343b0900] Formats: Original: nv12 | HW: cuda | SW:
nv12
How to reproduce:
ffmpeg version latest from git, Nvidia driver 570, Ubuntu 24.04.
vdr with vdr-plugin-softhddevice, -v cuvid.
I know about nvdec and softhddevice supports it too, here we are talking
about cuvid.
