Help building a pipeline

Hello,
I have right now this pipeline.

playbin2 | audioconvert | rgvolume | level | equalizer-10bands | rglimiter | volume | autoaudiosink

I want to attach this so I can record to a file all the output.
audioconvert | vorbisenc | gnomevfssink

I think the best is attach it just after the playbin2 using a tee. But I tried to do it and failed. How could this be done ? any example of something similar to this ?

Thanks in advance
J.Rios

Re: Help building a pipeline

You need a queue in each branch after the tee in order for pre-roll to complete. The queue buffers and splits the pipeline sections into different threads.

playbin2 ! tee name=t t. ! audioconvert ! rgvolume.... t. ! audioconvert ! vorbisenc ! gnomevfssink.....

It does not work like you do it above. playbin2 does not have any outputs you
can link to. two options:
1.) Use decodebin2 / uridecodebin
2.) use playbin2, but set audiosink to a bin that containes tee name=t ! queue !
autoaudiosink t. ! queue ! audioconvert | vorbisenc | gnomevfssink

Re: Help building a pipeline

I have done this

One bin called outputbin with this elements
tee ! queue ! audioconvert ! rgvolume ! level ! equalizer-10bands ! limiter ! volume ! audioconvert ! autoaudiosink

I attached this outputbin as "audio-sink" of a playbin

so i have
playbin ! outputbin

I then do the recordbin on demand of the user with this elements
queue ! audioconvert ! lame ! filesink

I add this recordbin to the outputbin and link the tee with the queue of the recordbin

the recording works correctly but while I im listening an online stream and recording I usually get this message (when running with --gst-debug=2)

0:02:58.811503553 32083 0x38845c0 WARN pulse pulsesink.c:523:gst_pulsering_stream_underflow_cb:<autoaudiosink2-actual-sink-pulse> Got underflow

and playback stops.

When its at this point the only way to restore is to restart the playback from start but I get some ref_count > 0 warnings.

I control when I receive BUFFERING messages and if so playback is restored fine. What Am I doing wrong?

Also when I receive tags I want to change the output file of the filesink so I need to do this

gst_element_set_state( recordbin, GST_STATE_NULL );
g_object_set( filesink, "location", uristr, NULL );
gst_element_set_state( recording, GST_STATE_PLAYING );

Its usually at this point when I get the underflow message but not always.

Thanks in advance for your help

no no. Please re-read my previous email. Playbin/playbin2 are pipleines without
pads, you cannot link to them. Please check the returns code of function calls
in your code, you will see that the linke for playbin ! outputbin will fail.
Pass outputbin to playbin (or better playbin2) by using the audio-sink property
instead.

Re: Help building a pipeline

Please re-read my previous email. I told you I attached the outputbin as audio-sink of the playbin (playbin2) in this case.

Anyway I think I have fixed the problem locking and unlocking the tee source pad of the record bin when doing the location change of the filesink.

Thanks
