I've tested some AV1 files, but does not have problem on 12900K iGPU or Arc A380. If it is DG1 specific, I might not be able to fix (as I don't have DG1 GPUs), in that case the error might be avoided by using --avsw (sw decoder).
Are there any sample files out which have this issue?
Thank you for your reply! On my computer, the following methods are mainly used to generate av1 videos. Currently, I do not have av1 videos from other sources. My CPU is 8700K. OBS 29.0.2 video recorded with svt-av1 encoding. Transcoded av1 in shanaencoder 5.3.
Video by OBS: 2023-03-17_11-50-13.zip
QSVEncC64 --avhw -i "2023-03-17_11-50-13.mkv" --device 1 --codec hevc -o "1.mp4"
Thank you for the sample file, I was able to reproduce the issue.
It seems to be a problem with AV1 in mkv format, I'll have it fixed in the next release.
Thanks for the fix! I just tested other MP4 encoded AV1 videos transcoded with shanaencoder with no problem, as you said it may be a problem with MKV format
I have updated to QSVEnc 7.36, which will be able to avoid this error.
I'll close this issue as the issue should have been solved.
My dg1 can decoding av1 with ffmpeg by using "av1_qsv". However, "QSVEncC64 --avhw" report error:
MFXDEC: Failed to DecodeHeader: unknown error.. InitMfxDecParams: Failed set param for hw decoder. : unknown error. QSVEncC.exe finished with error!
