I encountered an error in the files included in this patch when compiling
Chromium. When I followed this patch to modify the ffmpeg file in the
Chromium source code, the compilation no longer reported errors.
Chromium regularly merges the latest revisions of ffmpeg through
Cherry-Pick. I also

There are devices who return EAGAIN due to device blocking.

There is a difference: REDO is internal, EAGAIN

Instead of doing it ad-hoc in `filter_frame`. This is not a huge change
on its own, but paves the way for adding support for more formats in the
future, in particular formats other than AV_PIX_FMT_VULKAN.

This is done only to the inputs, not the outputs, because we always
output vulkan hwframes.
Doing so also requires keeping track of backing textures for non-hwdec
formats, but is otherwise a mostly straightforward change to the format
query function. Special care needs to be

NAK, there a difference in semantics: AVEROR(EAGAIN) is for when data is
not available for external reasons, typically

This can fix vp9 decode image corruption when the frame size is change,
but the pervious frames still be referenced.
Surfaces don't need to be bound to vaContext only after VAAPI 1.0.0:

The capacity can avoid hwaccel being uninited when do the reset. It
provides the method for hwaccel if it still want to use the previous
initialized configuration after reset. And the configuration can be
updated in AVHWAccel.init() if needed.
For example, when use vaapi vp9 decode dynamic

Hi,
The attached patch adds rendering of ATSC
Lavf only supports a very limited approximation of non-blocking
behavior, so we should not return random EAGAINs to callers unless they
specifically requested it.

There is no meaningful distinction between them, both mean "the demuxer

This is pointless now that demuxing always runs in a separate thread.
Remove special handling for AVERROR(EAGAIN), which should never be
returned now.

Makes sure EAGAIN from the internal ASF demuxer is propagated to the RTP
demuxer. Will be important in following commits.
