The alignment is handled by ff_default_get_video_buffer2. We
shouldn't use the aligned width/height as FFFramePool width/height.
It cause recreate FFFramePool inside ff_default_get_video_buffer2.
The recreate of FFFramePool together with multi-threads decoding
leading to data race and crash, for example,
./ffplay -f lavfi -i movie=foo.mp4,drawtext=text=bar
