Unset the variable to disable this facility. Detailed documentation for this specific topic can be found in the Xilinx Video SDK. or ask your own question. < ‎ |. I require to perform the latency test between the time from video encoding to decoding. Then forward that (I guess raw uncompressed data) to glupload and make colors good with glcolorconvert, since qmlglsink uses RGBA, and avdec_h264 is I420. So if you need also other processing beside grabbing the h264 frames (like playing or sending via network), you would have to use tee to split the pipeline into two output branches like example gst-launch below. It is found on the AM62Ax SoC. 4. Combined H. Conformance test Hardware-accelerated video decoding, encoding and processing on Intel graphics through VA-API. A demuxer contains one sink pad, through which the muxed data arrives, and multiple source pads, one for each stream found in Decode and stream h264 over udp with GStreamer. Some of the examples read or write RAW files from disk (encode-only or decode-only pipelines). creating complex topologies. 264 Decode (NVIDIA Accelerated Decode): To start Weston, complete the following steps before you run the GStreamer pipeline the first time with the Wayland backend.
