Compiling gstreamer1.0-plugins-imx for i.MX 6SoloX

ilariogottardel · ‎10-06-2015

Hi all,

I know i.MX 6SoloX doens't have VPU, but it has PXP and GPU-2D, so I would like to use these features for resizing video frames.

Problems is, I need the appropriate gstreamer plugins compiled, but if I add gstreamer1.0-plugins-imx to the image it gives me an error: libfslvpuwrap is not supported on my board (which is a mx6sxsabresd). If I modify the recipie adding mx6sx, it tells me that two packages provides virtual/libg2d, and a conflict stops the building process.

So, I'm stuck. My questions:

- is gstreamer the proper way to use PXP on MX 6SoloX? If not, how can I use this feature while decoding video with gstreamer?

- if yes, how should I patch the recipes to make the packages build?

- is official support for this cpu already planned on a future version of gstreamer-imx?

Thank you so much

Ilario

Hello,

According to “i.MX_Linux_Release_Notes.pdf”, table “Video codec specification
for hardware without VPU acceleration”, software codec implementation is provided.

As for PXP and GPU they are used in the following cases :

1) imxvideoconvert_g2d: GPU2D based video convert plugin, to perform video color

space conversion, resize, rotate

2) imxvideoconvert_pxp: PXP based video convert plugin, to perform video color

space conversion, resizing, and rotation.

Please refer to the recent BSP.

Have a great day,

Just to elaborate a little, this is the log when I try to compile (adding mx6sx to libfslvpuwrap):

It seems to me that libg2d is provided by gpu-viv-g2d and imx-gpu-viv, but the latter also provides libgles2 which is required.. and gstreamer gives compilation error if I try to hide gpu-viv-g2d.

The build has stopped as continuing in this scenario WILL break things, if not now, possibly in the future (we've seen builds fail several months later). If the system knew how to recover from this automatically it would however there are several different scenarios whic
h can result in this and we don't know which one this is. It may be you have switched providers of something like virtual/kernel (e.g. from linux-yocto to linux-yocto-dev), in that case you need to execute the clean task for both recipes and it will resolve this error. I
t may be you changed DISTRO_FEATURES from systemd to udev or vice versa. Cleaning those recipes should again resolve this error however switching DISTRO_FEATURES on an existing build directory is not supported, you should really clean out tmp and rebuild (reusing sstate
should be safe). It could be the overlapping files detected are harmless in which case adding them to SSTATE_DUPWHITELIST may be the correct solution. It could also be your build is including two different conflicting versions of things (e.g. bluez 4 and bluez 5 and the
correct solution for that would be to resolve the conflict. If in doubt, please ask on the mailing list, sharing the error and filelist above.
ERROR: If the above message is too much, the simpler version is you're advised to wipe out tmp and rebuild (reusing sstate is fine). That will likely fix things in most (but not all) cases.
