[gst-devel] adding tee to alsasink causing problems

[Rohan]

Hi James,

I am no expert but could you put the actual gst-launch commands you
are using, because it is not clear here where you use the tee twice,
for either.

I have been meddling with splitting audio/video but instead of for
saving to file, sending an image to the sender, as well as to another
receiving computer.

I am guessing this might give you what you want.  You do not seem to
be naming the tee, and calling it again.

gst-launch-0.10 v4l2src ! tee name=tee ! tee. ! queue ! \
video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! ffenc_flv ! \
ffmux_flv ! filesink location=/path/to/file tee. ! queue ! xvimagesink

I have not tried the same with the sound, but that should get your
video recording and displaying (nota bene: not tested, just an off the
top of my head guess)

For the sound the use of the tee should do the business.  I have not
messed with mux(es) yet, so I could have gone wrong there, but the tee
stuff should probably resemble the above.  You name the tee, and then
refer to it later in the commandline by name.

Hope this helps,

Rohan
