mfw_vpudecoder to ximagesink

[woutervh]

As I seem to have issues with video-timings when streaming video on our imx53 for a long time, I want to test it differently. 

I want the VPU to decode the frames, but let the kernel compose the image again afterwards. For that I want to try out ximagesink in stead of mfw_v4l2sink.

My approach would be:

DISPLAY=:0 GST_DEBUG=*:2 gst-launch-0.10 -vvv udpsrc multicast-iface=eth0 multicast-group=239.0.0.10 port=20011 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay access-unit=true ! mfw_vpudecoder parser=false ! mfw_ipucsc ! ximagesink

But I get first a warning:

0:00:00.203707250 1753 0xf4490 WARN mfw_vpudecoder /opt/yocto/fsl-community-bsp_fido/build_imx53/tmp/work/imx53qsb-poky-linux-gnueabi/gst-fsl-plugin/4.0.3-r0/gst-fsl-plugins-4.0.3/src/video/vpu_dec.full/src/mfw_gst_vpu_decoder.c:2116:mfw_gst_vpudec_check_allowed_caps: video sink does not support NV12, try I420

And after a while errors:

.......

Anyone knows what to add where? I don't see an issue...

Hi Wouter,

The vpu of the MX53 does not support NV12 and UYVY Fortunately, "mfw_ipucsc" can convert UYVY to I420!.
