Ultimately I have to develop an driver which will use Gstreamer pipelines to read and write mpegts files which contain KLV within data stream. At the moment however, I am just trying to learn how to put pipelines together using gst-launch. Once this is happy I'll try converting that into code. My problem at the moment is trying to get a basic output video which will play on a couple of media players. I have used the commands below to create an mpegts and this will play happily using FFPLAY, however with VLC it will simply show a blank screen. gst-launch-0.10 -e videotestsrc ! video/x-raw-yuv ! ffenc_mpeg2video ! ffmux_mpegts ! filesink location=test.ts I have tried replacing ffmux_mpegts with flutsmux to no avail. Can anyone point me in the right direction?
