Sorry, if I lost something - because it does not change something so far:
All three attempts result all in yuv422p10le as the previous 10bit hack did.

My summary follows:

/Cin

# git reset --hard e5a5a6da907dbcd40d8612bdbfeea1a2a0ae6cc8
HEAD is now at e5a5a6da Add onevpl support to build system

# git am 0001-yet-another-10bit-attempt.patch
Applying: yet another 10bit attempt


I didn't undestand Cingg should be recompiled additional after this patch(?)

--------------------------

My third Cin test using nv12

/Cin

# CIN_10BIT_ENC=nv12 bin/cin
Cinelerra Infinity - built: Nov 13 2024 20:54:33

hevc_vaapi_8b420.mp4
     cin_hw_dev=vaapi
     format=nv12,hwupload
     # profile=main
     # global_quality=22

** rendered 1780 frames in 41.675 secs, 42.711 fps
FFMPEG::open_decoder: some stream times estimated: 
/Videoklipp/Cineform/cfhd01.mkv


ffprobe -hide_banner hd01_hevc_vaapi_8b420.mp4
   Stream #0:0[0x1](und): Video: hevc (Rext) (hev1 / 0x31766568), 
yuv422p10le(tv, bt709/unknown/unknown, top coded first (swapped)), 
1920x1080 [SAR 1:1 DAR 16:9], 24375 kb/s, 25 fps, 25 tbr, 12800 tbn 
(default)

===========================

Some output for verification:

/Cin/cinelerra # egrep -i "10bit|tenbit|nv12|p010|y210" ffmpeg.C
GET_HW_PIXFMT(nv12,  AV_PIX_FMT_NV12)
         case AV_PIX_FMT_NV12:  ctx->get_format = get_hw_nv12; return *p;
     const char *tenbit_enc = getenv("CIN_10BIT_ENC");
         frames_ctx->sw_format = AV_PIX_FMT_NV12;
         if(tenbit_enc)
         frames_ctx->sw_format = av_get_pix_fmt(tenbit_enc);
         picture->format = AV_PIX_FMT_NV12;
