if the client doesn't resume the decoding process,
the decoder may keep waiting
in documentation of v4l2 stateful decoder, we can see the following

During the resolution change sequence, the OUTPUT queue must remain

abort the sequence and initiate a seek.

The code savings more than offset the size of the table
(1936B vs 768B with GCC 10.3 at -O3).

Would it be possible to have a quick review for this patch? It is pretty
straightforward.
Plus, this is its second submission. It already includes the requested
changes from the first time (~1y ago).
Thanks in advance,

This commit fixes the bug as report in https://trac.ffmpeg.org/ticket/9231 by
removing the line that overwrites the user settings for max_b_frames.

Somehow I missed this in fbb44bc51a647862eb05ae3f9d7d49a0be9bed57 ,
even though the lines were within the context. Probably the code
originally being after the this logic had something to do with it,
but previously it only touched the avformat context's codecpar,
which did not affect the encoder

Hi.
In case somebody is looking for a task to begin working on FFmpeg, I
have the following suggestion.
The program jpegtran, from libjpeg / libjpeg-turbo, can do lossless or
almost-lossless crop and rotate on JPEG, and even overlay with the most
recent versions.
I think this would be welcome

In some extrme cases, like with adpcm_ms samples with an extremely high channel
count, get_audio_frame_duration() may return a negative frame duration value.
Don't propagate it, and instead return 0, signaling that a duration could not
be determined.
Fixes ticket #9312

Some function had exceed 30 inline assembly register oprands limiation
when using LOONGSON2 version of MMI macros. We can avoid that by take
$at, which is register reserved for assembler, as temporary register.
As none of instructions used in these macros is pseudo, it is safe to
utilize $at
{SAVE,RECOVER}_REG will be avilable for Loongson2 again,
also comment about the magic.

Loongson3's extention instructions (prefixed with gs) are widely used
in our MMI codebase. However, these instructions are not avilable on
Loongson-2E/F while MMI code should work on these processors.
Previously we introduced mmiutils marcos to provide backward compactbility
but newly commited
