Steven, this sounds exactly like what I reported a few weeks ago with my 
Toshiba player.  Both VCD/SVCD and DVD formats had the same symptoms.  They 
did play on other, cheaper players.  As I'm a newbie to dvd production I 
can't say whether I am unwittingly producing the same burn circumstances, but 
it seems unlikely.  I stick to very simple commands, most of which have been 
posted on the list with my enquiries.

Just my 2p-worth to suggest that it may not be specific to JVC.

Yes, but the configure check isn't updated for it yet. You can do that
manually by changing configure.ac and the running ./autogen.sh.

Hi,
as i can see studio checks in configure.in for mjpegtools in this way:
dnl mjpegtools
AC_PATH_PROG(MJPEGTOOLS_CONFIG, mjpegtools-config, no)
if test x$MJPEGTOOLS_CONFIG = xno; then
 AC_MSG_ERROR(mjpegtools-1.6 is required to run this version of LVS. 
Please download it from http://www.sf.net/projects/mjpeg/)
else
 MJPEGTOOLS_LIBS=`$MJPEGTOOLS_CONFIG --libs`
 MJPEGTOOLS_CFLAGS=`$MJPEGTOOLS_CONFIG --cflags`
 MJPEGTOOLS_PREFIX=`$MJPEGTOOLS_CONFIG --prefix`
fi
AC_SUBST(MJPEGTOOLS_LIBS)
AC_SUBST(MJPEGTOOLS_CFLAGS)
AC_SUBST(MJPEGTOOLS_PREFIX)

In mjpegplay 1.7.0 is no more mjpegtools-config, how can i manually 
change this?

Tank you
Michael

[Mjpeg-users] Feeding frames to mpeg2enc

2004-10-11 Thread Dik Takken
Hi,
I develop scripts that generate MPEG2 streams by using imagemagick to 
draw the frames and using png2yuv to feed the frames to mpeg2enc. The 
problem I'm having is that all frames that are needed for the MPEG stream 
need to be stored on harddisk before png2yuv can start feeding them to 
mpeg2enc. The amount of required diskspace to store all these frames is 
HUGE, even when I use jpg frames in stead of png.

My question: Is there any way to have mpeg2enc "eat" frames while they 
are being generated?

For just a minute, I figured I could solve the problem by writing the 
frames into a named pipe, but imagemagick closes the pipe after every 
image. It seems like we need a simple front-end application that can watch 
a certain directory and concatenates any images that appear in that 
directory to it's stdout, like so:

framegrabber | png2yuv | mpeg2enc
Is this going to need a hack, or is it already possible?
Cheers!
Dik

Depends where you live I guess.  It's been trivial to take a couple
test DVDs to the local Circuit City (or Best Buy or whatever) and
ask to play a disk.

And the Apex (which is another inexpensive/cheap brand) hasn't had
any problem either.

There are times I would prefer that - better dark than washed out
(too light).

> You get what you pay for.

The Philips was not expensive (but it was not "cheap") and is the 
best DVD/SVCD player I've had yet - will play wildly out of spec 
VCDs/SVCDs and hasn't had any issues with the DVDs I've created.

I'm not sure it's an encoder issue.  I've taken mpeg2enc generated
streams and had them play on the ultra cheap players (Apex), a somewhat
more expensive Audiovox portable player, a midrange Sony and then
my Philips.   The only thing I can think of that I do differently is
use Apple's AC3 encoder and authoring programs (which perhaps the
muxing) rather than ffmpeg, mplex and dvdauthor.   mpeg2enc generated
streams work fine (turns out the MPEG-1 problem I'm having is NOT
the encoder's fault at all).

I wonder if it's the audio stream or mplex'ing that is causing the
problems you're having.  

Have you tried both MP2 and AC3 audio with the same results?

Unless the camcorder accidentally was set to the 32kHz mode ;)

The other possibility which I thought might have happened is that
'mp2enc' was used to encode the audio to MP2 and the "-r 48000" was
accidentally left out.  The old behaviour of mp2enc was to default
to 44100 - thus mp2enc would silently resample from 48000 down to
44100 :(

If/when you find time it would be a valuable data point to know if
the 1.7.0 (CVS) version of mjpegtools behaves differently.  If so, then
the problem's been fixed, if not then well, we're still on a hunt
for the cause of the problem.

Cheers,
Steven Schultz

[Mjpeg-users] full-quality Quicktime

2004-10-11 Thread Casper Koshinsky
Hi all,
I'm having the same problem as in a previous thread, but searching the 
thread yields no resolution.

Context:
I'm trying to use a DC10+ to capture a somewhat flaky video (old, recd 
on a different VCR, and with occasional tracking problems).  Although I 
have a VIA chipset on the mb, there is no problem with capture of 
recently recorded material.

lavrec works great and drops _no_ frames during recording of a single avi,
'lavrec -f a -i n -a 0 -q 100 -d 1 -t 3600 -w 1hrfilm.avi'
but it loses a dozen or so frames each time it opens a new file (using 
the %nnd numbering feature).  So I'd try
'lavrec -f q -i n -a 0 -q 100 -d 1 -t 3600 -w 1hrfilm.qt'
but this dies immediately with
**ERROR: [lavrec] Error writing to output file 1hrfilm.qt: Internal: 
broken JPEG format
++ WARN: [lavrec] Closing file(s) and exiting - output file(s) my not be 
readable due to error
No lower quality (e.g., -q 50) gets past this.  It is simply the '-d 1' 
that it doesn't like.

Does anyone know if libquicktime 0.9.2 --> 0.9.3 fixes this?  Or was 
there some other way to get around the avi 2GB limitation without 
sacrificing resolution?

Thanks -- C
