Hello!
I'm new to gstreamer
and this mailing list, so please don't blame me if I'm breaking any
rules.
I want to have a
functionality in my application that would enable user to record and playback
voice messages. I use speex plugin for that purpose. I have 2
problems:
1. For the purpose
of recording I'm using the pipeline suggested in speexenc example (speexenc
- oggmux) and recording is done on 2 channels by default. Due to the fact that
device I'm developing for has a simple mono microphone, the playback is done in
only one channel, which is unpleasant. What do I need to change to record in
mono mode? There's a description of src pad for speexenc:
name
src
direction
source
presence
always
details
audio/x-speex, rate=(int)[ 6000, 48000
], channels=(int)[ 1, 2 ]
and it has
channels property. Do I need to change that? How do I do that? I'm not too good
with the concepts of pads yet.
2. When I record
(even with gst-launch), the duration of the recording file that is created
is somewhat like 1 second shorter than the actual time I keep recording on. I
see such behaviour on my Ubuntu desktop and on openembedded-based
system. Is that a known problem? Is there a fix for
that?
Thanks!
Ivan.
