Sure we will share the test stream we met issue, via Wetransfer net
disk. I'm not sure if this is a driver issue or a soc cache issue, it
not occurs with any stream. Hope you can clarify it.
thanks for the stream, I have shared them internally with Sebastian who will
test them on his board (a TI board). We'll be able to confirm with you if we can
also reproduce the issues there, and that will help regarding possible SoC cache
issues.
Thank you for help.
It did run out the ram with h264_v4l2m2m if not do some modify, it
should be due to alignment.
What LibreELEC dev told me is that in absence of V4L2_CID_MIN_BUFFER_FOR*
controls, ffmpeg will allocate too many buffers and cause ram issue. We will
have this implemented in later update, so hopefully this problem will go away.
Based on what I've tried, ffmpeg re-allocate buffers as the width/height
was changed after VIDIOC_S_FMT/VIDIOC_G_FMT, with 1080P AVC.
p.s. are you interested in using 7110soc for verification? We can
provide the board for it.
Can you provide a status of what has been fixed from the SoC revision found on
BeagleV ? We stopped using the BeagleV for testing has it has SoC issue and no
known workaround for.
We are using board VisionFive 2, basically fixed the known soc issues in
the old BeagleV. Wave511 work quite well with omx-il on the board.
Thanks.
Som
