deepstream3.0:error about pipeline

hi,everyone:
i have 2 questions plz.
firstly,i play my pipeline with this.but something wrong happens(Got EOS from element “pipeline0”),how can i resolve this?

gst-launch-1.0 -v uridecodebin uri=file:///home/vapd/dps/deepstream-test3/sample_720p.mp4 ! nv.sink_01 nvstreammux name=nv width=1920 height=1080 batch-size=4 ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)RGBA" ! fakesink

secondly,after nvvidconv element,i want to know the stream-id about every frame from src_pad’s probe,how can i get the correct stream-id?it seen that stream-id always is 0;and nvstreammux must be set width and weight,is it said that i can’t get different resolution frame?

thanks u!

Hi,
Could you run sample app deepstream-app first and check the source code to adapt to your usecase?

form your sample pipeline, it is not clear to know what your usecase is. We have sample app and you can easily try other cases by modifying config files. We suggest you follow work flow of the sample app.

hi,DaneLLL
i have successfully started my pipeline,and save mat after the plugin of nvvidconv by probe created from src pad.but it is confused that how do i know the batched mat comes from which stream?because i do inference with 10 mats from the same stream.
thanks

Hi,
If you run deepstream-test3:

$ export GST_DEBUG=*:4
$  ./deepstream-test3-app file:///home/nvidia/a.mp4 file:///home/nvidia/b.mp4 file:///home/nvidia/c.mp4 file:///home/nvidia/d.mp4 file:///home/nvidia/e.mp4

You can see frame_meta->stream_id indicates each input source:

Can this help your case?
