Hi everyone!
It's provide ARMv8-A architecture, I used armv8-a ABI, but I have some problems with warptv, decodebin, h264parse, etc. elements. most of them situated in bad plugin. How can I use Gstreamer on this tablet?

I have this pipeline:
udpsrc ! decodebin ! queue ! videocrop ! queue ! autovideosink name=auto_sink sync=false", &error);

With it I got this error:
A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x2e8 in tid 13647 (gstglcontext)

I tryed to change it to this:
udpsrc caps=application/x-rtp,media=(string)video,clock-rate=(int)1,encoding-name=(string)MP2T ! "
                                              "rtpmp2tdepay ! "
                                              "tsdemux name=demux ! "
                                              "mpegvideoparse name=parse ! "
                                              "mpeg2dec ! "
                                              "queue name=src_queue ! "
                                              "videocrop name=video_crop ! "
                                              "queue name=sink_queue ! "
                                              "autovideosink name=auto_sink sync=false", &error);

But tsdemux video pad doesnt link with mpegvideoparse sink pad. I user pad-added signal.

Thanks!

I think solution was found. This is wrong video driver file. An old version of Gstreamer solved this problem.
Versions > 1.7.91 are throw this error.
ps. forgive my bad English.
