GStreamer pipelines and CLI commands for different GStreamer based features (process MPEG2-TS files, get video from DVB, deinterlace video, capture RTSP stream etc.)

GStreamer Pipelines

Capture RTSP stream to file

gst-launch-1.0 rtspsrc location=rtsp://10.82.131.240:8554/h264ESVideoTest ! rtph264depay ! h264parse ! mp4mux ! filesink location=file.mp4

Capture RTSP stream to files splitted to 10 seconds chunks:

gst-launch-1.0 rtspsrc location=rtsp://10.82.131.240:8554/h264ESVideoTest ! rtph264depay ! h264parse ! splitmuxsink location=file%02d.mp4 max-size-time=10000000000 

splitmuxsink test (overwritting max 2 files)

gst-launch-1.0 videotestsrc ! x264enc ! h264parse ! splitmuxsink location=file%02d.mp4 max-size-time=3000000000 max-files=2

Get TV Channel from DVB and save it in as series of 10sec long MPEG2-TS files
