-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello I have follow the README of the v4l2-mfc-encoder from the http://git.infradead.org/users/kmpark/public-apps it seems that I can use the mfc encoder in exynos4412(using 3.5 kernel from manufacturer). But I have a problem with the contain of the README and I can't get the key frame(the I-frame in H.264). It said that "6. Enqueue CAPTURE buffers. 7. Enqueue OUTPUT buffer with first frame. 8. Start streaming (VIDIOC_STREAMON) on both ends." so I shall enqueue buffer before start stream, to enqueue a buffer, I need to dequeue first, but without start stream, it will failed in both side. In this way I start OUTPUT(input raw video) stream first then dequeue and enqueue the first frame, then I start the CAPTURE(output encoded video) frame, dequeue CAPTURE to get a buffer, get the data from buffer then enqueue the buffer. The first frame of CAPTURE is always a 22 bytes frame(I don't know whether they are the same data all the time, but size is the same from m.planes[0].bytesused), but it seems not a key frame. What is the problem, and how to solve it. P.S I don't test the Linux 3.13-rc4, as the driver is not ready for encoder before.
