This fixes decoding av1-1-b8-22-svc-L2T1.ivf

av1-1-b8-03-sizeup.ivf on vulkan causes gpu hangs as none of the
images get resized when dimensions change, this detects the dim
change and calls the get_format to reinit the context.

Hi,
vf_libplacebo always goes through internal RGB conversion, even for no-op.
scale_vulkan (ditto overlay_vulkan) can be more efficient for simple YCbCr

In most cases, flv_read_metabody reads pass the beginning of the meta_pos.
If the beginning of the meta_pos had been flushed from the IO buffer,
we would not be able to seek to the right position (for a nonseekable stream).
Is better to check the seek result and skip the current flv body if

This way decoding error will not be returned when the user starts
draining the decoder, avoiding confusion over whether draining did or

Fixes failures of fate-h264-attachment-631 for certain numbers of frame

The goal is to distinguish between APIs provided by the generic layer to
