appsink-src.c file compilation error

[kunasiramesh]

Hi,

I am getting compilation error while compiling appsink-src.c file by this
command "*gcc -Wall appsink-src.c -o appsink-src $(pkg-config --cflags
--libs gstreamer-1.0 gstreamer-audio-1.0)*".

The error message is:

 In function `on_new_sample_from_sink':
appsink-src.c:(.text+0x60): undefined reference to `gst_app_sink_get_type'
appsink-src.c:(.text+0x7c): undefined reference to
`gst_app_sink_pull_sample'
appsink-src.c:(.text+0xd4): undefined reference to `gst_app_src_get_type'
appsink-src.c:(.text+0xf4): undefined reference to `gst_app_src_push_buffer'
/tmp/ccVGzia6.o: In function `on_source_message':
appsink-src.c:(.text+0x184): undefined reference to `gst_app_src_get_type'
appsink-src.c:(.text+0x1a0): undefined reference to
`gst_app_src_end_of_stream'
collect2: error: ld returned 1 exit status


Can anyone help me to resolve this issue?

Add gstreamer-app-1.0 to the pkg-config command.

Thank you for your reply. It is working now.
I want to know how much of data(ex: 1ms or 10ms etc..) Gstreamer is taking
from driver at each time to decode? Where I can find this details?
