Status on MFC encoding support?

[Peter Maersk-Moller-2]

Hi

What is the status on support for MFC supported video coding?

Are there any known effort to support hardware video coding for the Exynos family in GStreamer?

Allegedly Samsyng did get the drivers for videocoding via the V4L2 framework included in the kernel and they also did some work support through OpenMax, but I am not sure what the exact extend and implications of that work are.

Best regards

Peter MM

Hi Sebastian.

Thanks for the answer.

So, some efforts have been made ... some code exist that sort of work ... sometimes ... under certain circumstances. But the code has not entered mainstream. Is this correct? Sorry for the confusion. Read all the entries in the bug tracker, but a lot of informations seems to have been communicated in side channels.

How does one get the code (where does it reside) and do you think it is worth it at the current level?

Best regards

That is exact. The code needs more work before it can be upstreamed.
It's also limited to H264.

There is few people that hack it up in order to make it work on IMX.6
devices. I do believe Veo-lab as the most tested branch.

https://gitlab.com/veo-labs/gst-plugins-good/tree/v4l2-videoenc

I have a partly rewritten branch I started in order (not ready to be
shared) to be able to upstream it, though I have no strict date about
when I will resume this work.
