Hi) May be it's just bit-rate setting issue. Can you attach sample 11MB file? I will check the compression ratio of ffmpeg result and the original.

Yep, looks like it. ffmpeg -i minih264-output.mp4 minih264-ffmpeg.mp4 gives 770kb on my side or 6849 kbps. With h264enc_x64 -kbps6849 minih264_1920x1080.yuv out.264 I'm able to produce comparable size. But quality is...

Hi) Unfortunately, without any details, there is not much we can do. Development for small SoC can be hard (rv1109 looks powerful though). My only guess is possible stack overflow....

Thanks :) That seems to be the best way to solve this problem.

Hi) I do not see any noise problems compare to ffmpeg and lame: ``` ffmpeg -i 13384.mp3 -f s16le -acodec pcm_s16le out_ref.raw minimp3 13384.mp3 out_ref.raw out.raw rate=44100 samples=541534 max_diff=1 PSNR=119.083746...

After some experiments: * There no good enough ARM compiler to completely rely on intrinsics and do not use assembler. * Best known compiler - armcc, then clang and gcc8...

Thanks for such informative and useful issue) I will try to find some official documentation and fix it.

AFAIK patents applied to H264 usage in industrial scale, no matter which encoder used. But "royalties won't be charged for H.264 encoded Internet video that is free to end users"....

Hi) I'm not sure. But according to doc write() and close() is allowed in signal handlers: https://man7.org/linux/man-pages/man7/signal-safety.7.html so it's theoretically possible to call MP4E_close on app abnormal termination. If MP4E_close...

Hi) That's a good idea. Will do it at some point.
