+Subject: [PATCH 7/7] 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 sp5-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.
