I am attempting to playback an MPEG-TS file using the command:

nvidia@tegra-ubuntu:~/scripts/works/mpeg2$ gst-launch-1.0 filesrc location=/home/nvidia/HD_H264_06011_TS_ASYN_V1_001.mpeg ! tsdemux name=demux demux. ! mpegvideoparse ! omxmpeg2videodec ! nvoverlaysink -e

most of the examples show mpeg2tsdemux as the plugin, but it doesn’t show in gst-inspect-1.0.

Thanks for any pointers.

do you have the gst-bad-ugly set?

Please try
gst-launch-1.0 filesrc location= ! decodebin ! nvoverlaysink

Hi @kunice

Based on your mediainfo output, the video stream looks like H264 rather than MPEG2.

Video
ID : 481 (0x1E1)
Menu ID : 1 (0x1)
Format : <b>AVC</b>
Format/Info : Advanced Video Codec

Modifying you pipeline to decode H264:
gst-launch-1.0 filesrc location=/home/nvidia/HD_H264_06011_TS_ASYN_V1_001.mpeg ! tsdemux name=demux demux. ! h264parse ! omxh264dec ! nvoverlaysink -e
