[FFmpeg-devel] FFmpeg 6.1.2 about vulkan h264 video decode

[Wonskuis Yu(SH-RD)]

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
