If anyone has any objections, please let me know. ------------------ From: Jonas Karlman [ Upstream commit f270005b99fa19fee9a6b4006e8dee37c10f1944 ] The VIDIOC_ENUM_FRAMESIZES ioctl should return all frame sizes (i.e. width and height in pixels) that the device supports for the given pixel format. It doesn't make a lot of sense to return the frame-sizes in a stepwise manner, which is used to enforce hardware alignments requirements for CAPTURE buffers, for coded formats. Instead, applications should receive an indication, about the maximum supported frame size for that hardware decoder, via a continuous frame-size enumeration.
