https://github.com/mpeg5/xeve/releases
Hope Hybrid will add it.

thought about it end of last year, asked in the issue tracker (https://github.com/mpeg5/xeve/issues/96) never got a reply.
=> seems like a dead project, not worth adding

Can't even get xeve to work at all, using:

ffmpeg -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "G:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -color_primaries bt470bg -color_trc smpte170m -colorspace bt470bg -color_range tv  -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe - | xeve_app_base --verbose 2 --input stdin --input-depth 10 --input-csp 1 --fps 25/1 --codec-bit-depth 10  --rc-type 0 --qp 32 --profile "baseline" --level-idc 0 --range "limited" --videoformat "component" --colorprim "bt709" --transfer "bt709" --matrix-coefficients "gbr" --sar 1:1 --output "J:\tmp\2024-04-27@20_46_42_2210\test_1_2024-04-27@20_46_42_2210_01.evc"

I get:

=> okay, that was with the older version.
New version, fails for me too: https://github.com/mpeg5/xeve/issues/104

I managed to get the encoding working, but from the looks of it nothing can decode the output.
Since you asked for it: With what player did you want to decode this?

FFmpeg with the latest mpeg5 （MPEG-5） ·GitHub

Seems like MBAS (https://github.com/m-ab-s/media-autobuild_suite) does not contain evc support since it does not play the files I created with xeve.

Anything that doesn't use '--sar 1:1' doesn't work atm. (https://github.com/mpeg5/xeve/issues/105)

Let me know when normal ffmpeg can decode evc content and I'll add support for it in Hybrid.

interesting that "alienson2001.mp4" can be compressed (8%) using ZIP (??? )
