MediaCodec: Hardware decode wrong crop values on MediaTek SOC (width=319 height=239)

[littux]

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 -
