[Mjpeg-users] Bug in mjpeg 1.8.0
Title: Nachricht Good morning users, sorry for my english, but I hope your understand me. I have a problem with the version 1.8.0 in combination with the newest digikam-plugin (kipi-plugin for generate a mpg file for a images archiv). I see the error from ppmto4yuv that "Error: maxval==255. Actual value is 65365" - this is in the read function of yuv-header. The plugin uses the script images4mpg and calls many different tools. I'm using SuSE 9.3, if I use the rpm from SuSE with the mjpeg version 1.6.2 in the same configuration (didikam plugin, JPEG-files), than is all ok. Can everybody help me?

Actual value is > 65365" - this is in the read function of yuv-header. That means that the digikam-plugin is generating 2 bytes/pixel PPM data (values of 0 to 65535) instead of 1 byte/pixel (values of 0 to 255) ppmtoy4m only accepts 1 byte/pixel PPM data (maximum value of 255). > The plugin uses the script images4mpg and calls many different tools. Perhaps something in one of those tools is producing PPM data with a range of 0 - 65535 instead of the range 0 - 255. Oh, and one more thing about ppmtoy4m - in 1.8.0 the default output chroma sampling is 4:4:4. It will be necessary to either to use the "-S option (see 'ppmtoy4m -h') or resample the chroma using y4mscaler (see http://www.mir.com/DMG/Software/y4mscaler.html) Cheers, Steven Schultz --- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.

I had to use mjpegtools 1.6.x because of several quicktime issues. I was'nt successfull in using streamer with libquicktime-0.9.4: streamer -t $DAUER -b64 -i Composite1 -n pal -r 25 \ -s $AUFLOESUNG -o /temp/dvdwork/$DATEINAME.mov \ -f yv12 -F stereo -R $AUDIO -w $WARTEZEIT "Speicherzugriffsfehler" Using libquicktime-0.9.3 streamer works fine. Does anyone know how to use streamer(xawtv) with libquicktime-0.9.4? mjpegtools >= 1.7 require libquicktime-0.9.4, I think.

There are some features in the cvs version (0.9.8pre1) I'd like to use but I'll wait unti 0.9.8 is released. > > man y4munsharp > > > y4mshift -b xoff,yoff,xsize,ysize > > Thank you very much.

Ah, thank you! I knew I'd seen that before but couldn't remember the exact translation. Segment fault could be a bug in libquicktime-0.9.4 that was fixed in a later release. If that is true then upgrading to a newer libquicktime would be the fix. If that is not true then there's a bug in streamer - perhaps a newer version of 'xawtv' (if available) would be a good thing to try.

Not sure things have gotten that far yet ;) The first part of the problem is 'maxval == 65535' - something in the digikam-plugin is generating PPM data with maxval of 65535 (2bytes/pixel) instead of 255 (1byte/pixel). I didn't see anything in the above reference about that error. Might be still be related but that error wasn't explicitly mentioned. Following one of the links did lead to http://bugs.kde.org/show_bug.cgi?id=109739 where the error: **ERROR: [yuvscaler] Could'nt read YUV4MPEG header! is mentioned. That problem is because 'ppmtoy4m' defaults to 4:4:4. The fix is to add "-S 420mpeg2" to the ppmtoy4m program's options.
