Encoder endofstream problem (lost few final frames)

[nyanmisaka]

@mcerveny I managed to find a ffmpeg command that can be used to reproduce the problem. And your patch did fix it.

It seems that ffmpeg is not expecting codec->encode() to return EAGAIN while the encoder is draining/at eof (!frame). So what you added makes sense.

ffmpeg -init_hw_device rkmpp \
-f lavfi -i color=c=cyan:s=1920x1080:d=4:r=25,format=nv12 \
-f lavfi -i testsrc2=s=960x540:d=4:r=25,format=bgra \
-lavfi "[0:v]hwupload[main];[1:v]hwupload[over];[main][over]overlay_rkrga=format=nv12:afbc=1:eof_action=repeat:repeatlast=1,scale_rkrga=w=1280:h=720:afbc=1" \
-c:v h264_rkmpp -v debug -y /tmp/100frames.mp4
