OT: another DVD player emulator
by Andrew Randrianasulu 08 Jan '24

08 Jan '24

not exactly video player, more like interactive game console using dvd discs .... https://github.com/andkrau/NuanceResurrection/tree/master forum: https://www.thehelper.net/forums/official-nuon-dome-nuon-discussion.80/ as far as I understand it was some kind of multi-processor machine, with weird instruction set. with literally handful of titles ever released .... yet its emulator lives on! found via vogons forum.

PCSX2 DVD playback
by Andrew Randrianasulu 07 Jan '24

07 Jan '24

https://github.com/PCSX2/pcsx2/issues/1981 according to end of this issue it should work now, at least partially. New toy for me :) I think ps2 was more like those early embedded custom platform players than purely software things like xine/vlc. but we will see ....

ffmpeg raw dv profiles patch

AOM 3.8, again
by Andrea paz 03 Jan '24

03 Jan '24

I have compiled with both aom 3.8 and aom 3.6 patches without errors. The rendering test results are: aom 3.4: 34 fps aom 3.6: 39 fps aom 3.8: 48 fps The speed increase is noticeable. The videos result visually of the same quality. aom 3.4 and 3.6 give files of equal size while aom 3.8 gives a slightly smaller file.

SVT-AV1 encoding quite fast on x86_64

oof, there was typo in av1-svt.webm profile
by Andrew Randrianasulu 03 Jan '24

cfr instead of crf lower cfr values eat more memory as far as I can see. so they still commented out.

libsvtav1 as internal lib patch
by Andrew Randrianasulu 29 Dec '23

29 Dec '23

you need to repack orig tar.gz svt-av1 archive, I'll upload that separately. Disabled by default because it fails w/o patch on termux, but should be easier for users than messing up with external variables .... tar.xz of svt-av1 weighted 8.4mb but this is unavoidable considering interest in this particular encoder.

Updated x265 snapshot from another thread
by Phyllis Smith 28 Dec '23

28 Dec '23

This was from another thread - mixed in with libaom 3.8 - so wanted it to not get lost. Initial test on the x265 snapshot of 17122023 succeeded, but I have a lot more testing to do. For some reason my initial test core-dumped but when I ran it again, it worked so not sure why. (I broke more things today, then I fixed).
