This small memory leak was essentially responsible for keeping
decoding working at all.
The issue is that the codec profile must be attached to the frames
context. We created the codec profile at decoder creation time.
Which meant that if the decoder was destroyed, the context
became essentially u
Fixes a small memory leak.
This also prevents leaks on malloc/mutex init errors.
Does not depend on any other patches.
Patch attached.

This is a public field, settable before frames context initialization,
and propagated to any derived contexts.
API users can use it to store state and determine which context
is one of theirs.
This also allows decoders which create their own contexts to store
some state which would be freed only
The issue is that with a threadsafe hwaccel and multiple enabled
frame threads, hwaccel->uninit() is never called.
Previously, the function was guaranteed to never have any threads
with hwaccel contexts, so it never bothered to uninit it.
Patch attached.

Hi Stefano,
Here is the revised patch according to your suggestions. This should
allow for efficient inlining of the methods computing the map of
skipped macrobloks.

This switches the jpegxl_collect_codestream_header function to use
avcodec/bytestream2, which better enforces barriers, and should avoid
overrunning buffers with jxlp boxes if the size is zero or if the size
is so small the box is invalid.

mov_try_read_block() allocates 1MB at least, which can be more than
enough. It was called when reading saiz box, which can appear
periodically inside fmp4. This consumes a lot of memory.
We can fix mov_try_read_block() by clamp 'block_size' with 'size'.
However, the function is
