Hello,

I'm playing with the new video encoder plugin: v4l2h264enc.
I'm using DB410c with OV5645 camera and trying to capture a video and encode
it.
I'm running Debian Linaro release 17.04.
I've got the patches from https://bugzilla.gnome.org/show_bug.cgi?id=728438 and
tried them on both 1.12.0 and 1.10.4 (on 1.10.4 I had to also apply "pad: Add
API to get the current state of a task" patch). With both versions I get the
same error from video encoder sink pad:
gst_v4l2_video_enc_handle_frame:<v4l2h264enc0> error: Failed to allocate
required memory.
gst_v4l2_video_enc_handle_frame:<v4l2h264enc0> error: Buffer pool activation
failed

I'm attaching output log (gst pipeline is also there) and v4l2 log.
