Hello Vadim,
We've got a problem with ffmpeg. It doesn't define WORDS_BIGENDIAN which
is used in pixfmt.h, so
PIX_FMT_RGBA => PIX_FMT_BGR32
PIX_FMT_BGRA => PIX_FMT_RGB32
It explains the video color inversion ...
This is a thread about :

Maybe we simply need to add couple of #ifdef LIBAVCODEC_VERSION <
xxxxxxx
Thanks

No, I didn't modify this file. QuteCom compiled right away on my
system with this version of ffmpeg.
I'm going to downgrade to ffmpeg 0.5, available on macports to see if
it solves my problem.

Have you made some changes at
libs/pixertool/src/ffmpeg/pixertool-ffmpeg.c
to build QuteCom with this ffmpeg version ?
(if yes can you send your modification ?)

The latest ffmpeg-devel package available on macports (svn rev
18984).
libavcodec v0.52.

Well the low resolution was my mistake.
But the most anooying problem is the blue tint of the video
decoding.
I guess it's related to the "palette" error.
Any thoughts ?

Hi all,
I'm experiencing some troubles when running h263 video
calls with the
latest QuteCom source.
The video quality is very poor (wrong color settings, low
resolution,
low fps). It seems that the webcam driver cannot use the
iSight
integrated webcam properly.
Here is the log output when running a video call:
(error) 15:16:11 [Common] void
QuicktimeWebcamDriver::setupDecompressor(): can't get
channel sample
description:-9407
(warn) 15:16:11 [Common] virtual WebcamErrorCode
QuicktimeWebcamDriver::setPalette(pixosi): can't set palette
(info) 15:16:11 [Common] virtual WebcamErrorCode
WebcamDriver::setFPS(unsigned int): WebcamDriver is
running, can't
set
FPS
[h263p @ 0x3973200]rc buffer underflow
[h263p @ 0x3973200]vbv buffer overflow
The video quality is much better with the latest official
release
(v2.2
RC3).
Since the QuickTimeWebcamDriver didn't change for a long
time, I
guess
the problem is coming from somewhere else...
Anybody already encountered this kind of problem ?
Mathieu
