VLC for Windows not displaying ffv1 10/12/16-bit grayscale videos

I'm reporting an issue of VLC not displaying MKV videos encoded with ffv1 codec with 10/12/16-bit grayscale pixel formats.

With the latest version (v3.0.17.4), I cannot play back the ffv1/mkv encoded videos with the following console message (repeated for each frame).

[ffv1 @ 0000020065a746c0] get_buffer() failed
[ffv1 @ 0000020065a746c0] thread_get_buffer() failed

While no video window is shown, the progress bar on the playlist shows the correct duration and displays the progress.

Looking at the source code (libavcodec/ffv1dec.c), it appears these videos should be supported.

I've attached the test videos that I created with the FFmpeg (v5.0.1) commands:

ffmpeg -f lavfi -i testsrc=d=5 -vcodec ffv1 -pix_fmt gray test8.mkv
ffmpeg -f lavfi -i testsrc=d=5 -vcodec ffv1 -pix_fmt gray10le test10.mkv
ffmpeg -f lavfi -i testsrc=d=5 -vcodec ffv1 -pix_fmt gray12le test12.mkv
ffmpeg -f lavfi -i testsrc=d=5 -vcodec ffv1 -pix_fmt gray16le test16.mkv

test8.mkv test10.mkv test12.mkv test16.mkv

The 8-bit video is the only one plays on VLC while all the videos played back fine on ffplay.
