Hi, I'm developing a V4L2 mem2mem driver for the codadx6 IP video codec which is included in the i.MX27 chip. The capture interface of this driver can therefore return h.264 or mpeg4 video frames. Provided that the size of each frame varies and is unknown to the user, how is the driver supposed to react to a S_FMT when it comes to parameters such as the following? pix->width pix->height pix->bytesperline pix->sizeimage According to the documentation [1] I understand that the driver can just ignore 'bytesperline' and should return in 'sizeimage' the maximum buffer size to store a compressed frame. However, it does not mention anything special about width and height. Does it make sense setting width and height for h.264/mpeg4 formats?
