Problems with GStreamer 0.10 VPU plugins and Appsink (and WebKit)

Question asked by dv1 on Feb 22, 2013
Branched to a new discussion

Hello,

 

I have been using the GStreamer plugins for i.MX6 video decoding using a Yocto-based rootfs. I used the recipes from Freescale/meta-fsl-arm · GitHub for building (I used the danny branch). I used "imx6qsabresd" as the machine in Yocto's local.conf.

 

This gave me a kernel 3.0.35, and the following package versions:

firmware-imx-vpu-imx6q - 12.09.01-r4.0

gst-fsl-plugin - 3.0.1-r9.1

imx-audio - 0.1-r4

imx-lib - 12.09.01-r4.0

libfslparser - 3.0.1-r1

libfslvpuwrap3 - 1.0.17-r0

libgal-common-mx6 - 12.09.01-r1.0

 

When I tried to play a h264 video with GStreamer's playbin2 , it worked fine:

gst-launch-0.10 playbin2 uri=file:///media/mmcblk1p3/sintel_trailer-1080p.mp4

 

However, when I use an appsink as videosink, it breaks down:

gst-launch-0.10 playbin2 uri=file:///media/mmcblk1p3/sintel_trailer-1080p.mp4 video-sink="appsink"

 

I get errors like:

I never see these errors when using another sink, like mfw_v4lsink, fakesink, or fbdevsink.

This is relevant to me, because WebKit internally uses a derivative of the appsink for the video frames. In other words, the VPU GStreamer plugins will not work with WebKit.

 

Are the errors above known? Is there a newer version of the Freescale video decoder plugins which fixes them?
