 for raw camera files, including XDCAM and R3D. However, the absence of
 comprehensive R3D support in FFmpeg poses certain limitations. Given the
 importance of this feature for our project, we're considering sponsoring
 its development.

Comment (by yigithan):

 I am new at this project but looks like pixel format causes the problem.

 With {{{-hwaccel_output_format videotoolbox_vld}}} you are using
 {{{videotoolbox_vld}}} as {{{pix_fmt}}}. If you run like that
 {{{-hwaccel_output_format p010le}}} it should work as expected. I could
 not figure out how videotoolbox selects pixel format inside. But looks
 like it's supporting in the official documentation.

 I'm willing to sponsor the fix for this bug. I'll give $30 or more if the
 needed fix is more complex.

Comment (by quinkblack):

 I know there are multiple issues in hevc decoder, especially related to
 multi-threads.
 See the description at

 https://trac.ffmpeg.org/wiki/SponsoringPrograms/STF/2024#CleanupHEVCDecoder

 I'll take a look but it will take some time.
