triglm Posted February 7, 2016 Posted February 7, 2016 Hello, I'm trying to get the gstreamer pipeline to work with the i.MX h.264 hardware encoder and decoder. I've installed Trusty Vinilla http://mirror.igorpecovnik.com/Armbian_4.90_Cubox-i_Ubuntu_trusty_4.4.1.zip on a Hummingboard-Gate and followed the instructions for setting up the i.MX Gstreamer plugins here: https://github.com/Freescale/gstreamer-imx/blob/master/docs/debian-ubuntu.md gst-inspect-1.0 reports... $ gst-inspect-1.0 | grep imx imxvpu: imxvpudec: Freescale VPU video decoder imxvpu: imxvpuenc_h263: Freescale VPU h.263 video encoder imxvpu: imxvpuenc_h264: Freescale VPU h.264 video encoder imxvpu: imxvpuenc_mpeg4: Freescale VPU MPEG-4 video encoder imxvpu: imxvpuenc_mjpeg: Freescale VPU motion JPEG video encoder imxv4l2videosrc: imxv4l2videosrc: V4L2 CSI Video Source imxg2d: imxg2dvideosink: Freescale G2D video sink imxg2d: imxg2dvideotransform: Freescale G2D video transform imxg2d: imxg2dcompositor: Freescale G2D video compositor But when I try to run a pipeline with gst-launch-1.0 that includes imxvpudec I get the error message: [ERR] Can't open /dev/mxc_vpu: No such file or directory [ERR] IOSystemInit() failure. ERROR: Pipeline doesn't want to pause. ERROR: from element /GstPipeline:pipeline0/GstImxVpuDecoder:imxvpudecoder0: Could not initialize supporting library. Additional debug info: gstvideodecoder.c(2131): gst_video_decoder_change_state (): /GstPipeline:pipeline0/GstImxVpuDecoder:imxvpudecoder0: Failed to start decoder Setting pipeline to NULL ... Freeing pipeline ... I have tried rebooting, but the driver still isn't listed. I've made sure to have followed the step to install the firmware... $ ls -al /lib/firmware/vpu total 512 drwxr-xr-x 2 root root 4096 Feb 7 07:33 . drwxr-xr-x 8 root root 4096 Feb 7 07:32 .. -rw-r--r-- 1 root root 253968 Feb 7 07:33 vpu_fw_imx6d.bin -rw-r--r-- 1 root root 253968 Feb 7 07:33 vpu_fw_imx6q.bin What step am I missing? How do I get the proper device driver loaded?
Igor Posted February 10, 2016 Posted February 10, 2016 I am almost sure that this is not supported under Vanilla kernel. Next. You need to use the exact kernel which support bins were build for. Unfortunately kernel, for which support currently exists, is broken in some other areas - wireless, pci. If this is not a problem, than proceed with this guide and make sure you activate boot from kernel which will install with this process. It's not a perfect not fully tested solution and working only under Debian Jessie.
triglm Posted February 11, 2016 Author Posted February 11, 2016 Thanks for your reply. I need wireless and PCI in addition to the vpu so I'm trying the Solid-Run Image https://images.solid-build.xyz/IMX6/Deb ... 116.img.xz the vpu appears to work (still need to do more testing) but it looks like Wifi is not working for me on that either.
Igor Posted February 11, 2016 Posted February 11, 2016 SolidRun official images are built on that semi broken kernel ... of course mentioned bugs are present They are aware of the problems and things are in motion. I am not switching working kernel on behalf of VPU while loosing PCI and wireless. Armbian primary focus is headless stable base. As soon as things are fixed, we are switching to this kernel for which they are building VPU support. In the mean time it will become available (in few days) in repository under name: linux-image-dev-cubox ... so kernel switching and testing will be easy.
triglm Posted February 13, 2016 Author Posted February 13, 2016 Thaks! That would be great. I'll keep an eye out for it. Will you announce it here when it is ready? By "repository" do you mean we can get it by just doing an apt-get? Will it will be documented here http://www.armbian.com/kernel/(I don't see a linux-image-dev-* for hummingboard listed) or is there a github or something?
Igor Posted February 13, 2016 Posted February 13, 2016 Yes, it's undocumented since it was built first time yesterday and I have plans for auto weekly builds of all DEV kernels. You will be possible to use VPU upgrades but you loose onboard wifi and PCI ... and I haven't test this build. apt-get install linux-image-dev-cubox linux-dtb-dev-cubox Use on your own risk.
