The playbin plugin is not able to play 4k video on Jetson TX2

Hi all,

I'm trying to play multiple 4k video successively using Gstreamer on tx2, therefore, my first step is to make sure playing one 4k video works, so I try this line from the gstreamer manual: [code]gst-launch-1.0 filesrc location=rhino-4k.mp4 ! qtdemux name=demux demux. ! queue ! h264parse ! omxh264dec ! nveglglessink[/code] and it works like a charm!

However, I'm not able to play the 4k video using playbin: [code]gst-launch-1.0 playbin uri=file:///home/nvidia/workspace/gstreamer-try/rhino-4k.mp4[/code]

. It shows nothing but all the red stuff on the monitor and the log is like this:

[code]

And then I try to use playbin to play a 2k video, which works (playing the video smoothly) but still has segfault message like this:

My video is downloaded using youtube-dl on youtube: https://www.youtube.com/watch?v=7IWp875pCxQ

using this command for 4k video: [code]youtube-dl -f 266 <the url>[/code]

and downloading 2k via: [code]youtube-dl -f 264 <the url>[/code]

The reason I'm trying to use the playbin plugin is because I want to use the "about-to-finish" signal to play multiple videos gaplessly. So it's also great if anyone can give me a hint on how to implement this feature via customized pipeline. My pipeline code could be found here: [url]https://gist.github.com/chichunchen/6b06130e10b32df04f461729038634e7[/url]

Thanks!
