Hi,
I'm trying to make the coda960 h.264 encoder work on an i.MX6q SoC with Linux 4.14 and the 3.1.1 firmware.
# dmesg | grep coda
[ 4.846574] coda 2040000.vpu: Direct firmware load for vpu_fw_imx6q.bin failed with error -2
[ 4.901351] coda 2040000.vpu: Using fallback firmware vpu/vpu_fw_imx6q.bin

[ 4.932223] coda 2040000.vpu: codec registered as /dev/video[8-9]
Using gstreamer-plugins-good and the m2m v4l2 encoder, I have :
# gst-launch-1.0 videotestsrc num-buffers=1000 pattern=snow ! video/x-raw, framerate=30/1, width=1280, height=720 ! v4l2h264enc ! h264parse ! mp4mux ! filesink location=/dev/null

Video encoding failed
Decoder iws working OK with gstreamer, but fails to allocate memory with ffmpeg (unrelated).
Is there missing patches to make encoder work, or some specific parameters ?
Thanks,
Neil
