File output.mp4 has a background:
But I want to make 4 different frames instead of 1 frame showing 4 surfaces, I want your help, thanks for reading !!
File config dewarper:config_dewarper.txt (625 Bytes)
Configure:
You may use nvvideoconvert src-crop to parse the tiled video.

@Fiona.Chen I tried your example to crop with 4 videos but it didn’t work, here is the pipeline I use:
gst-launch-1.0 filesrc location=sample_office.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvideoconvert ! nvdewarper config-file=configs/config_dewarper.txt source-id=6 ! m.sink_0 nvstreammux name=m width=1520 height=1160 batch-size=4 num-surfaces-per-frame=4 ! nvmultistreamtiler width=1520 height=1160 rows=1 columns=1 ! tee name=t t.src_0 ! queue ! nvvideoconvert src-crop=“0:0:1520:290” ! ‘video/x-raw,width=760,height=580’ ! x264enc ! mp4mux ! filesink location=output0.mp4 t.src_1 ! queue ! nvvideoconvert src-crop=“0:290:1520:290” ! ‘video/x-raw,width=760,height=580’ ! x264enc ! mp4mux ! filesink location=output1.mp4 t.src_2 ! nvvideoconvert src-crop=“0:580:1520:580” ! ‘video/x-raw,width=760,height=580’ ! x264enc ! mp4mux ! filesink location=output2.mp4 t.src_3 ! nvvideoconvert src-crop=“0:870:1520:870” ! ‘video/x-raw,width=760,height=580’ ! x264enc ! mp4mux ! filesink location=output3.mp4
why can’t it output 4 videos, the pipeline only works with t.src_0, t.src_1 and t.src_2
Your crop parameters for t.src_2 and t.src_3 are wrong. Please read the document: Gst-nvvideoconvert — DeepStream 6.2 Release documentation

@Fiona.Chen oh, sorry for the confusion, thanks for the help.
Currently dewarper plugin can only output vertical surfaces.
Thank you so much for your help !
gst-launch-1.0 filesrc location=sample_office.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvideoconvert ! tee name=t t.src_0 ! queue ! nvdewarper config-file=one_config_dewarper.txt source-id=1 ! m.sink_0 nvstreammux name=m batch-size=2 width=1080 height=720 ! nvstreamdemux name=demux demux.src_0 ! nvvideoconvert ! x264enc ! mp4mux ! filesink location=videot.mp4 demux.src_1 ! nvvideoconvert ! x264enc ! mp4mux ! filesink location=videot2.mp4 t.src_1 ! queue ! nvdewarper config-file=one_config_dewarper2.txt source-id=2 ! m.sink_1
For each config dewarper will be 1 surface. But I try to run the above pipeline and it doesn’t work, can you help me fix it.one_config_dewarper.txt (2.4 KB)one_config_dewarper2.txt (2.4 KB)
No, the nvstreamdemux can not demux the multiple surfaces.
Please try the following pipeline:gst-launch-1.0 filesrc location=/opt/nvidia/deepstream/deepstream/samples/streams/sample_office.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! nvvideoconvert ! tee name=t t.src_0 ! queue ! nvdewarper config-file=config_dewarper_test0.txt source-id=1 ! m.sink_0 nvstreammux name=m width=3800 height=2900 batch-size=4 num-surfaces-per-frame=1 ! nvstreamdemux name=demux demux.src_0 ! queue ! nvvideoconvert !
