[gst-devel] Duplicates frames in h264 stream

[sudarshan bisht]

use export GST_DEBUG=element_name:5

What is your goal here ? You want an avi file having video width and height
1280x720 or 800x600 ? with frame rate 30 or 60 ?

And can you please tell us what is you sender application ? Is it some
gstreamer pipeline ?
