3e057dd8b1 avcodec/av1dec: Remove redundant second free
The AV1 decoder has the FF_CODEC_CAP_INIT_CLEANUP flag set and yet
the decoder's close function is called manually on some error paths.
This is unnecessary and has been removed in this commit.

92b578e1d6 avcodec/av1dec: Fix segfault upon allocation error
Up until now, the AV1 decoder always checks before calling its wrapper
around ff_thread_release_buffer() whether the ThreadFrame was used at
all, i.e. it checked whether the first data buffer of the AVFrame
contained therein is NULL or not. Yet this presumes that the AVFrame has
been successfully allocated, even though this can of course fail; and if
it did, one would encounter a segfault.
Fix this by removing the checks altogether: ff_thread_release_buffer()
can handle both unallocated as well as empty frames (since commit
f6774f905f).

e46f34e85b avcodec/av1dec: fix setting pix_fmt
Fill the array with the software pix_fmt and move the avctx->hwaccel
check back to the proper place.
Also remove the avoid probing flag to ensure an external av1 decoder
will not set a pix_fmt we don't want during format probing.

47be5a5056 avcodec: add AV1 hardware accelerated decoder
This AV1 decoder is currently only used for hardware accelerated decoding.
It can be extended into a native decoder in the future, so set its name to
"av1" and temporarily give it the lowest priority in the codec list.
