How to handle EOS from an appsrc to ensure all frames are played out before pipeline closes?

[Subodh Chiwate]

Hi All,

I am using the following pipeline in Gstreamer 1.2.3 on Freescale IMX6Q
board. But have noticed similar behavior on the x86 desktops as well.
Hence providing the basic pipeline structure.

[Local Media] - [Data Processing] - [AppSrc] --> [Parser] --> [Decoder]
--> [Sink]

I need to use large buffers in appsrc to ensure my processing benefits
from the head start, but I suspect that while EOS
the data in buffers might get flushed without being rendered.

Referring to the sample appsrc (
gst-plugins-base-1.2.3/tests/examples/app/appsrc-seekable.c )
application from source tar ball, I raise an EOS event from the appsrc
"need-data" callback when I run out of data.
The bus Handler exits gmain_loop.

How do I ensure that all the data still in the intermediate buffers is
played correctly before pipeline quits.
Is there any signal/condition I can wait on after getting the EOS before
I can set the pipeline state to NULL.
Please let me know in case I missed something already mentioned in the
Manual or PWG.
Thanks.
