[gst-devel] Help building a pipeline

[J. Rios]

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
