Re: [GEM-dev] can't get pix_movie working (follow-up)

Hi, Thanks a lot for your help > There is a DirectShow setting for DV quality and it defualts to > quarter resolution on some systems. The code for pix_movie tries to > force the quality to the highest and that works in my testing. Definitely sounds like that's my problem, or somehow related. It must be decoding at half or quarter resolution (I'd say half), so pix_movie's attempt to force the quality to the highest is failing in my case. > You > can try to alter the default using the GraphEdit tool in the > DirectShow SDK or find the registry value for it. I'm not sure how to do that. I downloaded this application: http://www.digital-digest.com/dvd/downloads/graphedit.html I don't know if it is the graphedit you're talking about and whether it was already installed. Following the direction I found in a forum (http://forum.doom9.org/archive/index.php/t-34818.html) I've been able to "insert" a DirectShow DV Decoder filter, right-click on it / "properties". In the abovementioned forum post, it was claimed that just by selecting "full" as the resolution and doing apply and close, it would cause DirectShow to use that default with any application. I found the setting was already on "full". However, I did apply, but it had no effect on GEM. It still renders at reduced resolution. By the way, both Virtual Dub and Windows Media Player decode DV files at full resolution and always did so on this machine. I also tried to search for the key in the windows registry but had no luck. I searched for "DV" (too many matches: aDVanced etc etc), "DirectShow", "quality", but I didn't find it. Any clue? Thanks a lot matteo P.S. avis coded with PicVideo MJPEG with 1:1:1 subsampling are decoded fine, but if I code them with 4:2:2 subsampling, GEM crashes (closes PD without even opening the typical windows crash dialog) when trying to play them. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: In REGALO 'All the Good Thing' di NELLY FURTADO Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=6617&d=20070615

Re: [GEM-dev] can't get pix_movie working (follow-up)

It seems to be a problem specific to the DV-PAL codec. I tried with an avi compressed with PIC-Video MJPEG, and it renders OK with gem-CVS20060412-NT-i686-bin, as well as with the unstable gem-0.90.1-W32-i586-bin version of 2004. Also, I tried with pix_film->pixdraw, and it shows the same behaviour as with pix_movie->rectangle or pix_film->pix_texture->rectangle. I.e., dv-pal avi's are rendered with degraded quality on the new version, while mjpeg avi's are rendered ok. So it seems there's something wrong in the way pix_film/pix_movie decodes dv-pal avi's. Note that the older version of GEM decodes them fine, and they look just fine on any other player, so it is not an issue of the codec, but an issue with GEM specific to that codec, introduced at some point after august 2004. My only workaround at the moment is to re-code all videos with MJPEG, which will be quite boring. Does anyone know of another solution?

missing [pix_write], that does only take pixes
by Roman Haefeli 08 Jun '07

08 Jun '07

hello everyone i just realized, that [pix_write], unlike [pix_record], takes its images from the framebuffer. when working exclusively in the pix-domain, using [pix_write] creates a huge cpu-overhead, that wouldn't be necessary, afaik. otoh, [pix_record] does crash to often to be used in everyday life. is there a way to capture single images from a pix-stream? if not, are there plans for a [pix_image_write] (or however this should be called)? roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de

./configure: line 8733: pkg-config: command not found
by Hans-Christoph Steiner 05 Jun '07

05 Jun '07

So in the auto-builds, the FTGL part of configure gives this error: checking linux/videodev.h usability... no checking linux/videodev.h presence... no checking for linux/videodev.h... no ./configure: line 8733: pkg-config: command not found checking for PKG_FTGL_CFLAGS... checking for PKG_FTGL_LIBS... checking for ftgl-config... yes checking for main in -lftgl... no When I run the build from a login shell, it works fine: checking linux/videodev.h usability... no checking linux/videodev.h presence... no checking for linux/videodev.h... no checking whether linker accepts "-L/sw/lib/freetype219/lib -L/sw/lib - lz -lfreetype -lftgl_pic "... no checking for PKG_FTGL_CFLAGS... -I/sw/include -I/sw/include/FTGL -I/ sw/lib/freetype219/include -I/sw/lib/freetype219/include/freetype2 checking for PKG_FTGL_LIBS... -L/sw/lib/freetype219/lib -L/sw/lib -lz -lfreetype -lftgl I think I found the source of the problem. My guess is that the Gem autoconf system relies on the environment's path. From my experience, all of the needed environment variables should be included in configure.ac so that the configure will. In this case pkg-config is in /sw/bin/pkg-config (Mac OS X does not include pkg- config). If a line something like this was added near the top of configure.ac, I think it would work: PATH="${PATH}:/sw/bin" .hc ------------------------------------------------------------------------ ---- http://at.or.at/hans/
