There isn't.

Also, I don't see the point. Do you need a larger buffer size on the TCP
connection because it takes too long for the pipeline to process a buffer?
Or do you want to optimize performance by reducing the number of buffers
passed through the pipeline? Or something else, still?

Regards,
Arnout

Yes. The "blocksize" property.

Re: Changing Buffer Size in SoupHTTPSrc

Wouter,

Thanks ... Ill try that out ...

To do that i have to do the connect signal as below and in the callback change the blocksize property. Is that how its done ?

// connect signal

g_signal_connect(G_OBJECT(playbin), "notify::source", G_CALLBACK(cb_playbin_notify_source), NULL);

Arnout,

I would like to reduce the buffer size to optimize performance. Currently everytime i stream, it takes a long time for the buffer to fill up.

Do you have an alternative ... is manually setting the pipeline to play an option ??

Thanks,

raj

Re: Changing Buffer Size in SoupHTTPSrc

Sounds complicated. Can't you just set the blocksize on the souphttpsrc
object?
g_object_set(G_OBJECT(src), "blocksize", 1024, NULL);

If you need an example pipeline:

gst-launch souphttpsrc blocksize=1024 location='<a href="http://207.226.88.71:8000'">http://207.226.88.71:8000' ! decodebin2 ! autoaudiosink

bfn, Wouter
