Hi, I need help with getting GStreamer to convert Mpeg2 files into MP4. No matter what I do, it would just keep on giving me error. Here is info from discover: /mnt/videos$ gst-discoverer-1.0 cut1.ts Analyzing file:///mnt/videos/cut1.ts Done discovering file:///mnt/videos/cut1.ts Topology: co…

Hi, Since Y42B is not supported in nvvidconv plugin. Honey_Patouceul’s pipeline is the optimal solution for transcoding: gst-launch-1.0 -ev filesrc location=test_mpeg2_422.ts ! tsdemux ! mpegvideoparse ! avdec_mpeg2video ! video/x-raw, format=Y42B ! videoconvert ! nvvidconv ! nvv4l2h264enc ! h264p…

Hi, You may refer to the posts: [image] Using GStreamer to transcode Video files with Hardware Accel Jetson Nano Hi, I am trying to convert a videofile from mpeg2 to h265 using omxh265enc. Transcoding the video stream works fine. However the file has an audi…

Hi, thank you for your reply. I saw it and tried it, and it just creates 0 sized mp4 files. /mnt/videos$ sudo gst-launch-1.0 qtmux name=mx ! filesink location=test.mp4 filesrc location= test.ts ! tsdemux name=dmx dmx. ! queue ! h264parse ! mx. dmx. ! queue ! aacparse ! faad ! audioresample ! audi…

Hi, cut1.ts has mpeg2 stream instead of h264. You should need to change h264parse to https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad/html/gst-plugins-bad-plugins-mpegvideoparse.html And audio from aac to MPEG-1 Audio.

Dane, thank you! I made a little bit of progress, but it is not perfect. I managed to get it to play! But then I tried to encode it into mp4 and whole hell broke lose again sudo gst-launch-1.0 qtmux name=mx ! filesink location=test.mp4 filesrc location= test.ts ! tsdemux name=dmx dmx. ! queue ! …

Hi, MPEG-2 is not supported in MP4, so you need to transcode it to H264(or H265) stream. FYR. We can run the command and get valid MP4: https://filesamples.com/samples/video/mts/sample_640x360.mts $ gst-launch-1.0 filesrc location=sample_640x360.mts ! tsdemux ! mpegvideoparse ! avdec_mpeg2video …

I was able to get this far: sudo gst-launch-1.0 filesrc location=/mnt/videos/stream1/20201218_122145.ts ! tsdemux ! mpegvideoparse ! avdec_mpeg2video ! nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=/mnt/videos/stream1/a.mp4 Setting pipeline to PAUSED … Opening in BLOCKING MODE …

Your problem is that your mpeg2 video is using 4:2:2 profile. You would have to convert into a suitable format for nvvidconv: gst-launch-1.0 -ev filesrc location=test_mpeg2_422.ts ! tsdemux ! mpegvideoparse ! avdec_mpeg2video ! video/x-raw, format=Y42B ! videoconvert ! nvvidconv ! nvv4l2h264enc ! h…

Hi, Since Y42B format is not supported by hardware converter, you need software converter for doing conversion. The takes certain CPU usage.

Indeed GPU is not involved here. The mpeg2 decoding is CPU only, and H264 encoding is done with dedicated HW encoder referred as NVENC in tegrastats. I’m a bit surprised by your numbers. On my XavierNX with L4T R32.4.4, I get these: # Boost your NX sudo nvpmodel -m2 sudo jetson_clocks gst-launch-…
