Summary of the bug:
I'm testing out an Intel Flex 140 card and I am attempting to transcode 4
inputs to 1 output using the xstack_qsv filter. My command takes in 4 udp
multicast ts files (h264 encoded) and outputs one h264_qsv encoded udp
transport stream.
The issue happens when one of the streams changes resolutions (from
1280x720 progressive, to 1920x1080 interlaced). I have attached a stream
that changes resolutions that causes this issue.
The stream will die with these errors if resolution changes:
[h264_qsv @ 0x55a240e68000] Error submitting the frame for encoding.
[vost#0:0/h264_qsv @ 0x55a240e30780] Error submitting video frame to the
encoder
Error while filtering: Internal bug, should not have happened
How to reproduce:
