gst playbin and log generation

Hi,

I am a newbie to gtsreamer.

I went through the documentation on the website and cloned the gstreamer and plugins and installed them.

I could test a couple of audios and videos successfully.

I used gst-launch=0.10 and generated logs with GST_DEBUG set to 5.

I read that there is a playbin application which does auto type finding and pipeline and graph building.

I want to generate a detailed log like gst-launch. I am not able to generate it.

Please advise me how to generate the detailed log.

I am trying to understand the internals of gstreamer by looking at the logs generated.

Thanks in Advance

Calling

gst-launch-0.10 --gst-debug=3 playbin2 uri=file://<path_to_your_file>

should give you a log that shows how playbin2 does things.

playbin is not an application, it's an element/plugin. You can use it
from gst-launch like this:

$ GST_DEBUG=*:5 gst-launch-0.10 playbin2 uri=file:///path/to/foo.avi
2>dbg.log

Cheers

Re: gst playbin and log generation

Hi Tim & Topi,
Thanks, it worked.
The only problem is the log is very big.
How can I understand the flow of the data, events and things like that. what I want is essentially an overview of the way the data flows, the no of threads that get created, the allocation of buffers and buffer management etc.
Regards

Hi,

> The only problem is the log is very big.

Log level can be set per category, like this:
--gst-debug playbin2:4

"gst-launch --gst-debug-help" lists up all the categories.
see gst-launch-0.10 (1)

Re: gst playbin and log generation

Hi TSUKADA,

Could you share more information about gstreamer debug system ?

This may help us learning gstreamer .

Thanks,
Bard
