Hi，
When I use ffmpeg 6.1.2 to do transcode as flow cmd: ffmpeg.exe
�Chwaccel vulkan �CI H264-4k.mp4 output.mp4
The assert of null pointer occur, after debug source code, I found the pointer
of layered_frame is null, because it doesn’t created.
Further, I found it only be created when dec->dedicated_dpb && dec->layered_dpb
are all true.
But the driver report caps only include
VK_VIDEO_DECODE_CAPABILITY_DPB_AND_OUTPUT_COINCIDE_BIT_KHR,
not include VK_VIDEO_CAPABILITY_SEPARATE_REFERENCE_IMAGES_BIT_KHR, it leads the
layered_frame can’t be created.
For this combination of driver caps, I think it means the reference frame and
output use the same image resource , the ffmpeg should create layered_frame as
array?
I’m confused whether It’s the driver issue or not?
Thanks,
WonskuisYu
