Mediacodec encoding not working

[RandomPerson]

Summary of the bug:
How to reproduce:

% ffmpeg -i video_input -c:v hevc_mediacodec output_video
ffmpeg version 7.1
built on r522817c) clang version 18.0.3 (https://android.googlesource.com/toolchain/llvm-project d8003a456d14a3deb8054cdaa529ffbf02d9b262)

Encoding with mediacodec is the problem, decoding works just fine

So mediacodec encoding just does not work, reaches EOF before even starting according to ffmpeg and exits with a very large negative exit code, no output stream either

[RandomPerson]

So I was wrong about the exit code it seems like

This is the default output when starting

[vost#0:0/hevc_mediacodec @ 0x7f39e7b600] Error while opening encoder - maybe incorrect parameters such as bit_rate, rate, width or height.

I guess this is the issue fixed by 4c0ef3bfae1473902f8ec8ee0a1a95607827b390, which is on branch the 7.1 branch and master branch, but not released in a new tag yet. Can you test the master branch? Or check whether specify a resolution which isn't aligned to 16 work, like:

ffmpeg -i video_input -c:v hevc_mediacodec -s 1920x1080 output_video
