GStreamer

  Anyone have success with GStreamer and Xenial Desktop? 

  Once upon a time (mid 2015) gstreamer used to work like this:  gst-launch-1.0 filesrc location=vid.mp4 ! qtdemux ! vaapidecode ! vaapisink

  Time has passed and the many parts that make up GStreamer (libva libcedrus vdpau-sunxi libvdpau gstreamer and gstreamer-vaapi) have evolved.

  I revisited this because I have recently stumbled upon an invocation that let's me play videos with hardware acceleration in gstreamer.  I'm trying

to stream h264 vid from my rpi-zero's camera to be saved/played/restreamed from my BPi ( i have both BananaPi and OrangePi+2e). 

This works-->

rpi$ raspivid -t 0 -w 1280 -h 720 -fps 30 -b 2000000 -o - | gst-launch-1.0 -e -v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host=rpi port=5000

bpi$ gst-launch-1.0 -e -v tcpclientsrc host=rpi port=5000  ! gdpdepay ! rtph264depay ! h264parse ! vaapidecode ! vaapisink

 As you can see, the bpi invocation of gstreamer is very similar to the original way gst-launch was called.

ps..

bpi$ export

declare -x VDPAU_DRIVER="sunxi"

declare -x VDPAU_OSD="1"

declare -x LIBVA_DRIVER_NAME="vdpau"
