Re: [Linphone-users] media_api in linphone

[Shivaji Navale]

Hi,

Thanks Simon!!

In mediatream.c did audio_stream_start_with_files
specified files /usr/tmp/media/input.wav (which is the copy of ur
hello8000.wav) and an empty /usr/tmp/media/output.wav.


It was difficult to sense what was going wrong while running linphone.
Which ran as normal as usual ( as if nothing had changed )

So executed the mediastream only from the command line as

mediastreamer/mediastream --local 7078 --remote 10.107.3.52:7080 --payload 
pcm8000
, the binary got executed well , with foll messages.

MediaStreamer-Message: Found /dev/dsp.
MediaStreamer-Message: Found ALSA device: Intel 82801BA-ICH2
MediaStreamer-Message: the pt->mime_type is string PCMU
MediaStreamer-Message: ms_filter_add_link: dskreader,0 -> MULAWEncoder,0
MediaStreamer-Message: ms_filter_add_link: MULAWEncoder,0 -> RTPSend,0
MediaStreamer-Message: ms_filter_add_link: RTPRecv,0 -> MULAWDecoder,0
MediaStreamer-Message: ms_filter_add_link: MULAWDecoder,0 -> dskwriter,0

(did exit it with Ctrl-C)

but there is no output in the output.wav, Although the file output.wav was 
being accessed as
seen from timestamps.

why arent the inputs and output being processed, the input file seems is
not even been accessed.

The communication is as usual for hosts with and without files and any of
its combination.

Is there anything else i am missing out, or the parameters from the
.gnome2/linphone  which solely define the way linphone behaves.


thanks,
shivaji
