mfxjpegenc issue with I420/YV12

[araani]

Hi,

Currently facing an issue with the mfxjpegenc component...

gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw, format=I420 ! mfxjpegenc ! filesink location=bad.jpeg and gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw, format=YV12 ! mfxjpegenc ! filesink location=bad.jpeg

results in:

gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw, format=NV12 ! mfxjpegenc ! filesink location=good.jpeg

results in:

I'm currently using the following version: SRC_URI = "git://github.com/intel/gstreamer-media-SDK.git;protocol=https;branch=release/mr3.1" SRCREV = "e476a3729e10340b7d1b5523c4ad19b14e74ba09"

Can you try from this repo?

https://github.com/ishmael1985/gstreamer-media-SDK

I tried running your pipeline and I don't see the same issue with my repo.

[ishmael1985]

It could be a kernel problem as well.

https://github.com/intel/media-driver/#known-issues-and-limitations

See point 1.

we are using intel apollo lake platform...

found kernel patches that mention the same thing in the yocto software reference design

https://github.com/intel/iotg-yocto-bsp-public/tree/e3900/master/meta-intel-leafhill/recipes-kernel/linux/linux-yocto

[ishmael1985]

In that case, it should work with the very latest on my repo, or from the https://github.com/intel/gstreamer-media-SDK/tree/topic_linux_and_window branch. I tested it on APL as well, but I used open-source MSDK with Linux Mint 18.3 (Ubuntu 16.04 base).

@araani , can we close this?

[araani]

the solution for the issue, as pointed out by ishmael1985

SKL: Green or other incorrect color will be observed in output frames when using YV12/I420 as input format for csc/scaling/blending/rotation, etc. on Ubuntu 16.04 stock (with kernel 4.10). The issue can be addressed with the kernel patch: WaEnableYV12BugFixInHalfSliceChicken7 commit https://cgit.freedesktop.org/drm-tip/commit/?id=0b71cea29fc29bbd8e9dd9c641fee6bd75f68274
