[gst-devel] problems with video

[Vinod Nanjaiah]

Yup! I missed out linking the gstinterfaces-0.10
It now builds when I use gst_x_overlay_set_xwindow_id.

For video seek, I tried a few combinations of the flags. 
I thought GST_FMT_DEFAULT would take FRAMES in case of video and so tried
that. But that didn't work. 
I am yet to try out gst_element_seek_simple with the flags that Tim has
mentioned.
Like Stefan had mentioned, I am using GST_SEEK_FLAG_NONE and it works for
audio.

Thank you!
Vinod

It would be useful to know what you've tried exactly ...

In any case, in a playback situation you usually want to

 - use GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_KEY_UNIT
 - seek in GST_FORMAT_TIME (remember the time is in nanoseconds)
 - use gst_element_seek_simple()

you need to add

 `pkg-config --cflags gstreamer-plugins-base-0.10`

to your CFLAGS / compiler flags and

 `pkg-config --libs gstreamer-plugins-base-0.10 -lgstinterfaces-0.10`

to your LIBS / linker flags as per:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-lib
s/html/gstreamer-interfaces.html

My guess is that it isn't a bug, as it doesn't happen all the time.
It's more likely something that I'm not doing quite right.  The annoying
thing is that it isn't very reproducable - it only happens sometimes,
and not on all of my PC's.  I have other "problems" in my app at the
minute in that I sometimes get a "bad drawable" x-window error - I guess
it's all related, but I haven't really had the time to track down the
problem yet.
