Comment (by vytskalt):

 I observe a very similar issue using the RADV driver on an AMD GPU.

 Sometimes it works, sometimes it doesn't. When it doesn't work, it either
 gives a random error number such as -455748544 or just simply segfaults...

 ./ffmpeg_g -y -init_hw_device vulkan=vk:0 -hwaccel vulkan
 -hwaccel_output_format vulkan        -filter_hw_device vk -i input.mp4
 -c:v h264_vulkan output.mp4

 [h264_vulkan @ 0x55b1e4d5d440] Encode failed: Error number -455748544
 occurred.
