Dear nicolas, sudip
Thank you for helping me.
Actually i did pipeline using videoparse and i already posted before.
When using videoparse getting a freezed image, no video playing and getting
error like
(gst-launch-1.0:290) Gstreamer-CRITICAL **:gst_buffer_fill:assertion
'GST_IS_BUFFER(buffer)' failed
caught SIGSEGV
#0 0Xb6bfc380 in poll () from /lib/libc. So. 6
#1 0xb6f164c0 in?? ()
Spinning. Please run gdb gst-launch-1.0 290' to continue debugging.
Buffer error still there. How can i solve it. Please help me
Thanks and regards
Abin
