[HELP] how to encode AVS2 to H265 video?

[ssdde]

i downloaded test5_avs2.mkv, and it can works fine. maybe you said 10bit avs2 can't support.

i want to send you the avs2 file which i need to encode to try.

[Selur]

okay,... send me a link.

[ssdde]

OK, when i uploaded i'll send you link by DM.

[Selur]

Got the file, but no clue what you want me to do with it,...

[ssdde]

keep that file and see if we can easily transcode it by Hybrid AVS2 10bit to H265 easily in the future.

[Selur]

As a side note, current error is:

[davs2 error]: Dec[ 0] 1cf02f6db40: Un-supported bit-depth 10 in this version

and using:

ffmpeg -i "PATH to 2025山东卫视中秋晚会_山东卫视-AVS2_10_06_19_28.ts" -t 30 -c copy "f:\avs2.ts"

you could have created a 30s sample, which would have been a lot smaller.

learned, thank you. and the error is not support 10bit AVS2, right? so Hybrid can't encode? how to solve? only wait for bestsource release new version?

[Selur]

and the error is not support 10bit AVS2, right?

yes

so Hybrid can't encode

Hybrid can't decode, so it can't encode it to something else.

how to solve?

BestSource and FFmpeg both use davs2 (https://github.com/pkuvcl/davs2) which does not support 10bit and which hasn't been updated in the last 3 years.
There is https://github.com/xatabhk/davs2-10bit which apparently (untested by me) aims to decode 10bit content.
No clue whether, it works or whether https://github.com/m-ab-s/media-autobuild_suite could support this to get ffmpeg builds that can decode 10bit avs2.
You would have to ask the BestSource, MediaAutoBuildSuite and maybe FFmpeg to add support for this.
Since avs2 isn't really something I encounter at all or that is requested a lot it doesn't seem to be really that well supported.

Ps.: you could probably use https://github.com/xatabhk/FFmpeg-avs2-a...s/tag/A5.X and replace the ffmpeg.exe with their build to at least reencode it while only using FFmpeg (NoSynth).

[ssdde]

is this works?

download this:
https://github.com/xatabhk/FFmpeg-avs2-a...64-EXE.zip

then replace ffmpeg.exe in zip with C:\Program Files\Hybrid\64bit\ffmpeg.exe?

i can encode avs2 10bit to h265 by hybrid?
