[PATCH v2 18/18] media: mtk-vcodec: venc: fix invalid time per frame in S_PARM

From: Alexandre Courbot
Date: Fri Jun 26 2020 - 04:06:38 EST


v4l2-compliance expects the driver to adjust the time per frame if it is
invalid (numerator or denominator set to 0). Adjust it to the default
value in these cases.
