GStreamer i.MX6 Decoding

GStreamer i.MX6 Encoding

GStreamer Transcoding and Scaling

GStreamer i.MX6 Multi-Display

GStreamer i.MX6 Multi-Overlay

GStreamer i.MX6 Camera Streaming

GStreamer RTP Streaming

Other plugins:

Will the imx6 vpu encode and decode plugins work with gstreamer-1.0?

[LeonardoSandova]

OtavioSalvador, can you help me answering ronsharp question from the Yocto point of view?

The biggest problem here is not the build system but the ABI used in the binary libraries. I doubt it'll work out of box so it might need a rebuild of the plugins which I doesn't know if it is doable or not.

[ronsharp]

Thanks. Yes, it will not work as gstreamer-1.0 has a different interface between plugins. I guess the question was when you will support gstreamer-1.0. It will require changes to the code. Alternately, do you offer the source so we can modify it? Also is there any general "gstreamer on IMX" documentation you can point me to other then this blog? Thanks for your support.

WangZening, do you know if there are plans to migrate the gst-fsl-plugin to support gstreamer 1.0?

ronsharp, the gst-fsl-plugin source code is available either with LTIB or Yocto. You can try the fsl-image-gui image with Yocto.  Once the image is built, the source code (on your host machine) is under build/tmp/work/imx6qsabresd-poky-linux-gnueabi/gst-fsl-plugin/. Yocto documentation is found here

[OtavioSalvador]

ronsharp the interface with Gstreamer is Open Source; so please if you get it working with 1.0 share you code changes so we can integrate them in Yocto ;-)

Hi,

I am looking to use vpudec along with gstreamer 1.x plug ins. Please advise how we could I compile vpudec with gstreamer 1.x ? I have got gstreamer 1.x plugins cross compile, but dont know what to do for vpudec. I am using timesys build at the moment.

Thanks a lot.

Regards

Alok

My transmitting device has a IMX6 q processor board .My goal is to transmit a video and simultaneously check for the range. The receiver also has the same configuration (IMX6Q)

gst-launch filesrc location=/root/tx/scripts/Bugsbunny.mpg blocksize=152064 ! 'video/x-raw-yuv,format=(fourcc)I420, width=352, height=288, framerate=(fraction)30/1' ! vpuenc codec=5 ! matroskamux ! udpsink host=HOST ADDRESS port=PORT NUMBER sync=false async=false

the output is like this:

Setting pipeline to PAUSED ...

And then it exits.

Kindly suggest any changes.

Regarding the previous question...

gst-launch filesrc location=/root/tx/scripts/Bugsbunny.mpg blocksize=152064 ! 'video/x-raw-yuv,format=(fourcc)I420, width=352, height=288, framerate=(fraction)30/1' ! vpuenc codec=12 ! matroskamux ! udpsink host=HOST ADDRESS port=PORT NUMBER sync=false async=false

That is what I tried but with same result.
