R32.6.1-t210: gstreamer H264 decode pipeline not working

[madisongh]

Describe the bug
Testing with wip-dunfell-l4t-r32.6, jetson-nano-devkit-emmc, core-image-sato.

The sinteltest gstreamer test program does not display video, showing mostly black with maybe an occasional still frame from the video. This test does work OK on TX2 and Xavier.

Using nvgstplayer-1.0 to play the video does work OK, though. That player uses the (long-deprecated) nveglglessink plugin for output, instead of the nv3dsink plugin, hence the suspicion that there's something wrong with that plugin vs. others in the pipeline.

Needs further investigation.

Hey @madisongh

Could you please share the Gstreamer pipeline ?

[madisongh]

If you're building one of the images in the demo distro that includes the gstreamer-tests recipe, you'll find it in the sinteltest script that gets installed.

I will give it a try

I've tried substituting nveglglessink for nv3dsink in the script's pipeline, and ran into the same issue. So perhaps there is some issue with the way the pipeline is constructed that's causing the problem. It's just odd that it works OK on the t186 and t194 Jetsons.

I re-ran the the test today, and it's working fine. I'll close this as unreproducible now, and just put it down to things being somewhat messy while the the update was still a work in progress.
