Re: [gst-devel] GStreamer videotestsrc could not show in QWidget

did you init the gst? did you start the gst main loop?

maybe its nothing, but when i use ximagesink as a sink i use also xvi-outpout instead of screen_sink

also maybe you should try running the gst from a command line (gst-luanch) to see whether you have problem that are not code related

did you init the gst? did you start the gst main loop?

Tom : yes, i invoke gst_init(&argc, &argv) in main function. because i use gst in QT, so i'm not start gst main loop. i had look other QT app, it's not start gst main loop also.

maybe its nothing, but when i use ximagesink as a sink i use also xvi-outpout instead of screen_sink

Tom: i'll try this. but other app use screen_sink also. it could be work fine in nokia N810.

also maybe you should try running the gst from a command line (gst-luanch) to see whether you have problem that are not code related

Tom : yes, i running gst-luanch in command, the videotesetsrc is work fine. i think it's my code problem, not in gst itself.

Re: [gst-devel] GStreamer videotestsrc could not show in QWidget

i also use gst with qt

and i start the main loop according to gst document

in my application i have a video thread, and i pass to it the widget Wid, i start the main loop, i set the gst elements, set the overlay, and then run the main loop (g_main_loop_run)

if you dont use the loop of the gst, i think you should implement a loop of your own, waiting for gst event and "paint" each "frame" to the widget...
