yesterday evening, the following command crashed (allways but once!) with
[Parsed_vpp_qsv_2 @ 0x563c3523f780] Can't allocate a surface
as long as the vpp_qsv filter was present:
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -i 'rtsp://url'
-vf 'hwupload=extra_hw_frames=64,format=qsv,vpp_qsv=detail=50' -c:v
h264_qsv -global_quality 30 -look_ahead 0 -bf 16 -profile:v high
-level:v 5.1 -trellis 2 -threads 1 -an -f flv 'rtmp://url'
Today it suddenly works as it does on other computers (with other rtsp streams).
Does anyone have any insights into this?
Thanks a lot!
