I'm having a little bit of difficulty constructing pipeline using DV.
I'm basically tring to monitor a dv stream so I using something like
gst-launch dv1394src ! dvdec ! xvideosink
This works. Additionally it works to send it to osssink or artsdsink as in
gst-launch dv1394src ! dvdec ! artsdsink (or osssink there)
However, I can't figure out how to enter the pipeline for doing both at the
same time on the gst-launch command line. Because of this I designed the
pipeline in gst-editor. Both of the above pipelines worked properly. When I
try to output to both at the same time I have some serious audio problems
with oss or some less serious but still unusably annoying problems with
artsd. OSS sounds like its being heard through a helicopter (but video is
pretty normal) and when through artsd the video and audio pauses every
second or two. I took this to mean that my machine wasn't keeping up. I am
less concerned with latency in this application than with sync'd audio and
video at a decent quality. Is the software not quite to this level yet and
that is my real problem? Is it my hardware can't keep up? Can I convert this
to some other format and play that with fewer problems, if so how might that
pipeline look?
Thanks in advance for your help. If you don't mind can you CC me on response
to this as I have not actually subscribed to the list.
Thanks
Dustin
