RX 6700 XT and AMF Runtime 1.4.26 / SDK 1.4.26 issues
quamt opened this issue · comments
Hello when using the AMF Runtime 1.4.26 / SDK 1.4.26 and RX 6700 XT together with VCEEnc (x64) 7.11 (r1236) there are some strange issues and behaviours.
- When selecting bframes there is always an error message but these has not been set:
storage->SetProperty(BPicturesDeltaQP)=6 failed: invalid param..
storage->SetProperty(ReferenceBPicturesDeltaQP)=4 failed: invalid param..
-
When converting AVC to AVC usage of bframes crashes the decoder
-
Usage of --pa lets the decoder crash too
Attached debug logs
After further investigation it seems to be that the error is related to the source files and certain settings in the decoder/encoder.
Meaning, depending on the source file the AMD decoder is "choking" on the file when certain options are enabled.
I also noticed after lots of investigation that lookahead causes "choking" when --avhw is used.
Using --avsw and lookahead is not causing any trouble.
One very strange part is that the CPU/GPU usage is very low when using either --avsw or --avhw, at least that what the task manager shows.
- BPicturesDeltaQP, ReferenceBPicturesDeltaQP
It seems like they are not currently supported yet.
decoder/PA crush
I also have pre-analysis sometimes crushing, but cannot find the reason or condition which causes the error, because it sometimes works fine and sometimes don't. The debugger shows crush in the amf runtime module, which makes hard to debug.
I might need to check further.
decoder/PA crush
This should have been fixed in VCEEnc 8.00, which improves stability when using pre analysis.
Ok. Thank you.
I will check and feedback.
Look fine.
Thank you.
