 Summary of the bug:
 When using {{{-hwaccel mediacodec}}} on Android, the output resolution is
 always 319x239 on my phone with a MediaTek SOC (MediaTek Helio G80). The
 video is improperly cropped and there's a green line on the bottom of the
 video (See "mtk_wrong_crop_result.mkv" attachment)

 Meanwhile, it works fine on my other phone which has a Snapdragon 680
 (Same ffmpeg build).

 How to reproduce:
 Just use {{{-hwaccel mediacodec}}} on any file (On a phone with a MediaTek
 SOC)
 {{{
 % ffmpeg -hwaccel mediacodec -i file -f null -
 }}}
