Jorge Ramirez-Ortiz 44188993a1 avcodec/v4l2: set sizeimage param for non-raw buffers [fixes #6716 ] Some V4L2 drivers fail to allocate buffers when sizeimage is not set to a max value. This is indeed the case for s5p-mfc [1] Most drivers should be able to calculate this value from the frame dimensions and format - or at least have their own default. However since this work around should not impact those drivers doing the "right thing" this commit just provides such a default. The calculations were extracted from the v4l2 driver used to develop the ffmpeg v4l2_m2m support [2].
