Hi when I try and install mjpegtools-1.6.1 I get this error with the configuration process (ie when I type ./configure):
checking for GLIB - version >= 1.2.0... no *** The glib-config script installed by GLIB could not be found *** If GLIB was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the GLIB_CONFIG environment variable to the *** full path to glib-config. configure: error: "You need to install GLib - you can find it on The problem is that I just can't configure, compile and install GLIB on my CYGWIN system. I am running CYGWIN on windows NT (X86) build system type... i686-pc-cygwin host system type... i686-pc-cygwin and I have the latest gcc installed and everything else that GLIB needs. My question is: Is there any way of installing mjpegtools without having to install GLIB? or is there a special process for installing GLIB that I am not aware of. thanks Kwaku -----Original Message----- From: Ronald Bultje [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 11, 2003 12:31 PM To: Abrokwah, Kwaku Cc: [EMAIL PROTECTED] Subject: Re: [Mjpeg-users] Introduction to MJPEG: Focus on Architecture andImplementation Hey Kwaku, On Mon, 2003-06-09 at 22:15, Abrokwah, Kwaku wrote: > I have a beginning to intermediate knowledge of what it entails. > I am currently looking for information on how the various jpeg stream are organized > architectually into the mjpeg file.

Well, as I said, that's just MJPEG in an AVI container, do you'd probably want to look through Microsoft's or IBM's RIFF/AVI documentation to get a good fundamental understanding on that. Or do you mean the MJPEG video strwam on itself? (Really, this is as simple as a stream can get, it's just a sequence of JPEG images (in YUY2 colorspace), no special markers, nothing). > I am currently trying to convert YUV still frames to MJPEG.

That's what the AVI container handles. Every data chunk in a RIFF file (AVI) is preceeded by an identifying tag (00db for video, 00wb for audio) and then a 4-byte size value with the least-significant byte first (so a uint32_t on little-endian systems). Then the data itself. The data chunks are preceded by the normal AVI header (RIFF header, vids/strf:vids header and auds/strf:auds header). After the data chunks usually comes an index of all the data chunks, though this isn't necesssary. For YUV-to-MJPEG/AVI, we use the yuv2lav tool, you'd probably want to look at the sources there to get a good basic understanding of all this. If you just want to use the tool, take our latest RPM (1.6.1).
