Help needed regarding buffering

[Vijay Vikram]

Hi ,

Thanks for your response to my queries but my prob still remains in the
same state.

I would restate my issue first.
I have a pipeline which has the following elements in the same sequence as
mentioned below

httpsrc->queue2->demux

For queue, my code snippet looks like this-

GstElement *queue = gst_element_factory_make( "queue2", "data" );

g_object_set (G_OBJECT (queue ), "max-size-bytes", 10MB, "max-size-time",
0, "max-size-buffers", 0, "use-buffering", true, NULL);

httpsrc pushes data in chunks. I am expecting the queue to hold the data
chunks till 1MB(10 percent of the max size) is filled. But what i see is ,
queue pushes data to the demux as soon as it gets the first chunk.

I tried using "temp-location" property, but in that case data is always
pushed to the file specified in the "temp-location", and it never comes to
the queue.

Please suggest (if possible with code snippet) how to achieve it.

Please correct me if I am going wrong with my pipe itself.

Regards,
Vikram
