Can GPRS steal bandwidth from voice?
Hello everyone,
I am a newbie to this, and if you know of an informative URL that has
relevant information, please point me to it.
Suppose a cellular subscriber gets a PocketPC (Windows Mobile 2003 Phone
Edition), and subscribes to a voice + Internet plan. He then decides to
use a proprietary VoIP application using the Internet plan. He is not
using the voice part of his plan; he is channeling

Variable bitrate and bandwidth usage
Hi -
Suppose I have a Q-1 Vorbis stream being served from a machine on a
low-bandwidth internet connection. I listen to the stream locally using
Winamp, which shows the bitrate fluctuating between around 35-55 kbps,
the average being 48k.
Now suppose I have 10 external listeners connected. How much bandwidth
will they need/use? Common sense says:
average bitrate * 10 = 480kbps (plus any

[PATCH 01/18] media/v4l2: remove V4L2-FLAG-MEMORY-NON-CONSISTENT flag
From: Sergey Senozhatsky <sergey.senozhatsky at gmail.com>
The patch partially reverts some of the UAPI bits of the buffer
cache management hints. Namely, the queue consistency (memory
coherency) user-space hint because, as it turned out, the kernel
implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT.
The patch revers both kernel and user space parts: removes the

[PATCH 05/28] media/v4l2: remove V4L2-FLAG-MEMORY-NON-CONSISTENT
The V4L2-FLAG-MEMORY-NON-CONSISTENT flag is entirely unused, and causes
weird gymanstics with the DMA_ATTR_NON_CONSISTENT flag, which is
unimplemented except on PARISC and some MIPS configs, and about to be
removed.

.GSM -> .WAV (or ,MP3) Conversion
Hey there,
I'm trying to convert some call recordings from asterisk we have in .gsm
format to something I can pipe through ffmpeg - wav would be good, mp3
would be amazing!
I've been trying playing with sox but I don't seem to be getting too far
with
1239101491.30.gsm -ql -r 64000 -t wav 1239101491.30.conv.wav resample
as ffmpeg borks at it:

Could you explain what makes you think it's unused? It's a feature of
the UAPI generally supported by the videobuf2 framework and relied on
by Chromium OS to get any kind of reasonable performance when
accessing V4L2 buffers

Odd icecast hiccup problem with low-bandwidth cellular client
Here's a very odd question - I don't know if anybody can even begin to
answer.
I am attempting something very odd and geeky. I set up an icecast Win32
server streaming a 96kbps mp3 stream (using all the latest as of today
software, winamp, icecast2 and oddcast v3) so I can listen to it on my cell
phone while at work.

Wine and video4linux2 supported webcams
Hi everyone!
I'm trying to get clarification about v4l/v4l2 support in Wine. As there is no definite answer anywhere in web.
I'm using Logitech webcam which is fully supported by v4l2. However, when I'm trying to use it with simple cam capture program in wine, I can see only that device is there, but I can't do anything else with it. I also did a little digging and so have found
