*I can play a video in 1024x768 resolution but I need it in 1920x1080:
When I issue the command:*
/GST_DEBUG=2 gst-launch-1.0 filesrc location=/home/root/sd/test2.mp4 !
qtdemux name=demux demux.video_0 ! video/x-h264 ! avdec_h264 ! videoconvert
! ximagesink/
*
It plays, but in the wrong resolution.
So I change it to:*
/GST_DEBUG=2 gst-launch-1.0 filesrc location=/home/root/sd/test2.mp4 !
qtdemux name=demux demux.video_0 ! video/x-h264, width=1920, height=1080 !
avdec_h264 ! videoconvert ! ximagesink/
*and I get the following error:*
/root@uz3eg-iocc-2018-2:~# GST_DEBUG=2 gst-launch-1.0 filesrc
location=/home/root/sd/test2.mp4 ! qtdemux name=demux demux.video_0 !
video/x-h264, width=1920, height=1080 ! avdec_h264 ! videoconvert !
ximagesink -v
