The pipeline SRC=./vid.mp4 && gst-launch-1.0 -v filesrc location="$SRC" ! qtdemux ! h264parse ! decodebin ! videoconvert ! autovideosink works perfectly if DS6.1 is not installed, but gives the following error once it is:

The pipeline also works fine in a development environment (python gst-env.py) where DS plugins aren’t available.

Try this.
SRC=./vid.mp4 && gst-launch-1.0 -v filesrc location=“$SRC” ! decodebin ! nvvideoconvert ! video/x-raw ! autovideosink

Yes, nvvideoconvert works, but should videoconvert break after installing DS?

5

What do you mean?

7

Considering that videoconvert works without having DS6.1 installed, is it normal for it to fail after installing DS6.1?

8

It should not break with Deepstream installed, what error you met?

As per the original question, I’m getting the follow when videoconvert is used:

gst-launch-1.0 filesrc location=$SRC ! qtdemux ! h264parse ! decodebin ! videoconvert ! autovideosink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

Same result for gst-launch-1.0 filesrc location=$SRC ! decodebin ! videoconvert ! autovideosink

nvvideoconvert works fine though.

Since you installed Deepstream, decodebin will choose nvidia decoder to decode the video, the decoded byte stream are in GPU memory video/x-raw(memory:NVMM), you need nvvideoconvert to convert it to CPU memory, for autovideosink to connect with.

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
