Comment (by Eric Karnes):

 I've since updated to FFMPEG 6.0 and am using Ventura 13.4 and the bug is
 still present however I'm given more information in the logs

 [vp9 @ 0x7f84cf704080] Format videotoolbox_vld chosen by get_format().
 [vp9 @ 0x7f84cf704080] Format videotoolbox_vld requires hwaccel
 [vp9 @ 0x7f84cf704080] Unknown VideoToolbox session creation error -12907
 [vp9 @ 0x7f84cf704080] Failed setup for format videotoolbox_vld: hwaccel
 initialisation returned error.
 [vp9 @ 0x7f84cf704080] Format videotoolbox_vld not usable, retrying
 get_format() without it.
 [vp9 @ 0x7f84cf704080] Format yuv420p chosen by get_format().

 error -12907 seems to correlate to "kVTCouldNotCreateInstanceErr" while my
 Mac's console gives the error

 [VP9] GVA error: ailed to create context
