 Current behavior:
 When trying to encode a video with a resolution not divisible by 16 (e.g.
 1080p) with Android MediaCodec, the resolution is aligned to 16 pixels
 (1920x1088). If the output is H.264 or H.265, this gets mitigated by
 cropping the stream with `h264_metadata` or `hevc_metadata` BSF.

 How to reproduce:
 {{{
 % ffmpeg -i input.mkv -c:v vp9_mediacodec -b:v 4000k -c:a copy out.mkv #
 input.mkv is a 1080p video

 % ffprobe out.mkv # displays 1920x1088
 }}}

 Proposed enhancement:
 There are other methods to make sure that the output is 1920x1080 instead
 of 1920x1088:
 - setting `crop-bottom` (and `crop-right`) on `MediaFormat`
 (https://developer.android.com/reference/android/media/MediaFormat#KEY_CROP_BOTTOM).
 Unfortunately, it's only supported on API level 33+
 - allowing the user to opt out of the alignment, as a lot of hardware can
 produce 1080p (or possibly other arbitrary resolution) output.
