Hello,
When running the following gst-launch command to "play" a video as root, everything seems to process fine based on the plethora of debug prints I added to the code.
gst-launch-1.0 filesrc location=/path/to/video.mp4 ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! ducatih264dec ! queue ! fakesink
However, if I run the same command as another user (not root), it quickly errors out with the following messages:
ERROR: Failed OmapDrm_FD > 0 error val -7
ERROR: Pipeline doesn't want to pause.
Looking further up in the debug prints, I noticed that the drmOpenDevice calls for /dev/dri/card0 and /dev/dri/card1 both failed with an error 13 (permission denied).
So my question is: is it possible to successfully play a video on a non-root account or will videos only play with root permissions?
Thanks.
