gstmfxfilter.c:274:gst_mfx_filter_prepare: Unable to query VPP allocation request -15

[hexray-newbee]

the following command works on i7-7700HQ, but not on J1900:

gst-launch-1.0 filesrc location=input.h264 ! h264parse ! mfxh264dec ! autovideoconvert ! simplevideomark ! fakesink

errors on J1900:

simplevideomark is an element of libgstvideosignal

[ishmael1985]

This could be the result of a new VPP output format and other optimizations introduced by the following commits:

https://github.com/ishmael1985/gstreamer-media-SDK/commit/9c94f2f54db9c40da7d55442d1c6b54446b490f6 https://github.com/ishmael1985/gstreamer-media-SDK/commit/4f533bb108db3cc480ea62c7a8d7f7dc03e3f4ec

With newer systems such from Haswell onwards, YUY2 output format is supported. Baytrail (J1900) and Ivybridge I suspect doesn't have such support, so unless a newer driver which allows the feature to be supported, you should force the caps:

gst-launch-1.0 filesrc location=input.h264 ! h264parse ! mfxh264dec ! video/x-raw, format=NV12 ! autovideoconvert ! simplevideomark ! fakesink

You can also try the following to get better performance but it might not work on the J1900:

gst-launch-1.0 filesrc location=input.h264 ! h264parse ! mfxh264dec ! video/x-raw, format=NV12 ! mfxvpp ! simplevideomark ! fakesink

[hexray-newbee]

I've tried the new commandline. Same erros.

[ishmael1985]

First one or second one? First one at least should have no errors.

[ishmael1985]

Also you can try to install the latest drivers to see if it resolves your issue.

Pls let me know what you get.

[hexray-newbee]

same errors, and I let it output warnings as following.

And I've tried replacing autovideoconvert with videoconvert. it works!

[ishmael1985]

It seems autovideoconvert invokes mfxvpp to perform the NV12 ->YUY2 conversion, which the J1900 unfortunately doesn't support. Have you tried with the latest driver?

[hexray-newbee]

the last two comment above were tested under the latest driver.

[ishmael1985]

That's bad. GST-MFX doesn't yet have a mechanism to determine the hardware support for colorspace conversion before finalizing the output caps. From Haswell onwards, NV12->YUY2 is supported and I enabled it for performance reasons. Can you help confirm to me what other platforms you test to get this error? Then I can work on a way to disable it for those platforms (Baytrail, Ivybridge, etc.).

[hexray-newbee]

I'am glad to help you. But, it's a pity that I have only Baytrail, Braswell and Kabylake. And only Baytrail runs with the error.

[ishmael1985]

Thanks as well for your feedback :) It's fine. I can't just disable YUY2 output format support unless I am sure which hardware doesn't support it. I assume that 3rd gen Intel HD graphics (Baytrail, Ivybridge with HD 4000) doesn't support YUY2 output format in video / system memory. While you confirmed it for Baytrail, I need to confirm it for Ivybridge as well before I do something about it.

[ishmael1985]

Also if you do have have the time to test, can HEVC Main 10 decode work on Braswell? You can get some samples here: https://kodi.wiki/view/Samples
