Hi gan

one can try with nxp plugins described in sect.7 Multimedia

attached Linux Guide. As for imxvpuenc_h264 and gstreamer-imx plugins

- they are supported by community:  https://lists.yoctoproject.org/listinfo/meta-freescale

There are 2 separate plugin's : community GStreamer-imx plugins and
nxp GStreamer Plugins, difference between nxp and community gstreamer plugins :
http://trac.gateworks.com/wiki/Yocto/gstreamer

Best regards
igor

thinks, i have got imx-gst1.0-plugin-4.1.1

i want use appsink, appsrc for preview and record live video. recording files  5min/per .

v4l2src -> appsink  (m_src->pushSample(sample))  // m_src = appsrc

appsrc->imxvideoconvert_ipu->clockoverlay->vpuenc_h264->filesink

QGst::CapsPtr caps = QGst::Caps::fromString("video/x-raw, "
"format=(string)YUY2, width=(int)720, height=(int)576, "
"framerate=1/25, pixel-aspect-ratio=1/1");
m_qsrc.setCaps(caps);

when start the two pipelines, got errors : streaming task paused, reason not-negotiated (-4)
