flac.webm profile does not work anymore?
Looking at Terje's problem with libvorbis audio I noticed flac.webm profile does not work, and ffmpeg 4.4.4 already complaining you can't put flac audio in webm. So, I guess we better to remove this profile?
OK, I will test it too. BTW: I can not help with the NVENC problem as I can not get it working anywhere: https://www.cinelerra-gg.org/forum/forum-hardware/run-h264_nvenc-mp4-via-nvi... On Sat, Dec 30, 2023 at 10:33 AM Andrew Randrianasulu < [email protected]> wrote:

mmm ... I need to re-test this with updated ffnv headers .... I see user uses new driver (makes sense for supported card), but I am still not sure how compile-time choice of ffnv headers affects different drivers (nvidia dropped support for Kepler cards lately. So, no new driver for me)

Also flac does not work for me with webm and vorbis produces a "dirty" output.

can you try to up vorbis bitrate by adding like "b 160k" parameter to vorbis audio webm profile ? Or alternatively "global_quality 5" (from '-1' as very poor to '10' as best)?
It doesn't change with any bitrate or quality value I've tried, always a disturbance above normal sound. Of all the sound presets in webm only opus produces a clean result, the others have the same noise (even opus_ffmpeg) while flac does not start rendering and freezes all of CinGG.

Just a question: I don't really understand the relationship (if there is any) between flac.webm and vorbis in webm using CinGG? When I encoded VCT-AV1 with FFmpeg, there was no issue with Vorbis audio in .webm :

I guess at some point ffmpeg's webm muxer was allowing muxing flac in webm, but then it was disabled due to being not in webm spec? I guess we can copy av1-svt.webm to av1-svt.mkv (and edit first line there to start from matroska, name of the full muxer. webm is smaller "web" subset of it, as far as I understand) so more sound codecs can be tested? When I encoded VCT-AV1 with FFmpeg, there was no issue with Vorbis audio
in .webm
this is good to know, but for having bug isolated we probably need some debug on sound buffer format conversions inside cingg... I am not yet sure how to do this. Thank you anyway for bringing this to our attention!
:
I created an "av1-svt.mkv" preset to do further testing on vorbis and flac. vorbis and opus_ffmpeg still produce audio with noise. Flac works clearly and all other mkv audio presets also work clearly. I attach the preset. PS: I also tried to create an av1-svt.mov preset but the render freezes CinGG similarly to how flac did with webm ("can't quit while a render is in progress", but the render freezes at 0%)

The flac.webm profile was removed in GIT. In addition, I removed previous out of date libraries to include: libvpx-1.13.0 libwebp-1.1.0 tiff 4.5.0
