Hi, I tried MLP/trueHD audio encoding in CinGG, but it was failing even
with "strict -2" set in option files, probably need this patch:
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/808a6717e0c584738c60a109afd6...
GG tried with this patch with truehd and it still failed. He will check into GIT dca.qt but not mlp or truehd. Since the patch as quoted above was only created in July/August, maybe at some future date it will be an automatic part of an ffmpeg release and be fixed to work. Even if it worked, he does not want to take the chance of carrying a patch that may or may not be later incorporated into a standard release.
OK, I understand this.
QUESTION for you -- why "threads=2" in nagicyuv.qt and utvideo.qt ? GG is OK with this, but was wondering if that makes it run better on your computer ? And is there a limit of only 2 ? Just curious...
Simply because I have 4 core machine (AMD quad-core, family 15h - so, some features shared between cores) and I want to capture some heavy stuff like qemu-system-ppc :} Feel free to change on commit. PS: thanks for pix_format explanation! PPS: v410 also saw some threading optimizations - http://ffmpeg.org/pipermail/ffmpeg-devel/2019-October/252135.html [FFmpeg-devel] [PATCH v1] avcodec/v410dec: add the frame and slice threading support
