shinchiro created an issue

I get crashed randomly in a few video file with --pmode on. Using 52782ae and running on Ryzen 7 1700.

    Hi Shinchiro,

    Can you please share the command line you have used, so that we can look this issue from our side.

    Thanks Ashok.

    Commandline: --crf 23 --preset veryslow --ctu 32 --max-tu-size 16 --limit-tu 2 --rdpenalty 1 --ssim-rd --psy-rd 2.0 --rc-lookahead 60 --aq-mode 2 --aq-strength 1.2 --bframes 6 --deblock 1:1 --splitrd-skip --pmode --pme --no-rect --no-amp --no-b-intra --no-weightb --no-psy-rdoq --no-rdoq-level --no-strong-intra-smoothing --no-sao

    Some extra info since I think there is race condition bug somewhere

    sure

    I also passing along these switches when compiling /favor:AMD64 /arch:AVX2 /GS- /GL /Gw

    Unfortunately, we don't have access to a Ryzen machine to test this out. I don't see the same crash on an Intel x86 machine.

  8. shinchiro reporter

    I wonder if you're still tracking this issue. If yes, I would like to add a few bits observations I saw till now.

    Encoding with pmode on while browsing using firefox quantum will constantly making it crash somewhere

    Leaving the encoding alone without doing any sidework will not crash. Using microsoft edge also doesn't crash

  9. Ashok Kumar Mishra

    You need to look into the application you are working to solve this issue. We can't track this issue since the standalone encoder is working fine with --pmode and --pme. We don't have access to Ryzen m/c. Please check the below log for a test with your command line.
