According to Phoronix 22 May 2025 :
- FFmpeg FFV1 Vulkan Encoder Lands +35% Improvement For AMD,
+50% For NVIDIA
- No word on Intel performance benefits from this Vulkan encode
optimization.
AFAIK Intel has not yet QSV support for FFV1 either.
Any idea which ffmpeg version release ffv1_vulkan will be available
?
I guess "upcoming", I saw references to 8.0 in commits.
And which color bit depths will be supported: 8-bit yuv422p and
10-bit yuv422p10le/ y210 ?
Speed tests?
Speed was not great for my rx550 (few fps for 4k video), but may be Arc actually faster for such workloads?
I see at least those mentioned in ../thirdparty/ffmpeg.git/libavcodec/ffv1enc_vulkan.c
if (avctx->sw_pix_fmt == AV_PIX_FMT_GBRP10 || avctx->sw_pix_fmt == AV_PIX_FMT_GBRP12 ||
avctx->sw_pix_fmt == AV_PIX_FMT_GBRP14)
so high-bit depth RGB is supported.
I'll try to synthetize Vulkan ffv1 encoder preset and see what it offers.
