I'll be glad to help on that also. there are a few other things I'd like to improve : - libquicktime support (not as easy as it seems to be imho) - ffmpeg swscale support (i had submitted the patches) - perhaps using system toolame rather than rebuilding it - cinelerra contains some executables stacks, I had tracked it to the way images are packed in the executable in guicast but didn't fix them - cinelerra contains text relocations on x86 when compiled with mmx in libmpeg3 iirc, I have some patches against libmpeg3 asm, I could contact the author to see if he wants this to be integrated here (of course removing the need for textrels usually makes the asm slower so it is only acceptable with a "notextrel" option) Anyway, since cinelerra is my favorite soft for video editing I'd like to help you by contributing a bit more, perhaps starting by trying to track the bugs you mentioned. The only problem being I don't have as much time as I'd like to to play with video, but that's life ;) Regards, Alexis pgpQ0tnUQL4ZP.pgp Description: PGP signature
Re: [CinCVS] my cinelerra involvement
That's great Dan! I was just reading some of your posts over on kino-dev. I use dvgrab to capture my footage via live stream from my camera, and I am thinking of upgrading to an HD camera so this is great news. I know that Dan Dennedy mentioned this capability on The Linux Link Tech Show a few weeks ago. Perhaps your patch was what he was talking about. Anyway, I am glad to see that you are thinking of helping with Cinelerra!!

I've just finished writing a patch to add full HDV read support to dvgrab and am about to send that off to their mailing list, so my next project was going to be working some more on cinelerra, since I use it exclusively for video editing...so, I'll be glad to help as much as I can. Probably not at a super fast pace, but I can provide some help. I was planning next on adding direct support for reading files with ffmpeg (libavcodec/libavformat).

Currently I rather care more for infrastructure enhancements and cleanup than outstanding bugfixes but I believe that this will pave the road to find/fix bugs much easier in future (at least for me). > > I believe we can be a bit more liberal with svn access, since we really > have a big problem at hand... I think so far the git way worked well, looking at the repositories which are mirrored here, there are people actively working on cinelerra on their git branches. For me hosting git mirrors from pipapo.org turned out to be less problematic than I expected (bandwidth/traffic/support wise). Imo it would be nice to bless the git repos more official, maybe even phase out SVN and turn over to git entirely. This gives much more freedom in workflow since anyone can hack in his own branches. We could pick up Linux kernel like policies and add 'Signed-off' comments to reviewed commits etc. Some ideas/notes: - Would it be possible to run a git mirror service on cvs.cinelerra.org? - Anyone else having a server which can offer git mirroring? - There is repo.or.cz which offers free mirroring too. - a anonymous (untrusted) pushable git repo on pipapo.org (how about such on cinelerra.org?) - I would offer some help when setting up git things on cinelerra.org - How about a monthly developer meeting on IRC, 1 hour where we can discuss who works on what, where progress is made, who needs help with something and so on. Exact time&date acknowledged on the mailinglist, Someone makes a protocol about the outcome and puts it online and so on? - when will then entire cinelerra.org site be a wiki? :) Christian ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
Re: [CinCVS] my cinelerra involvement
(freezing when moving edits when having multiple tracks being one of them) andraz, just for you to have a small feedback on this, since i've been pretty much working exclusively with cinelerra and depend on it to be very stable, i've been using a rafael2k debian-stable package for version v2.0, which is the most stable release i've seen. especially due to what you mention above - it doesn't happen there. here in brazil, even though i do have an hdv camera, about 95% of everything being done here is still dv, so v2.0 is already very fine to do about anything (usually, people get surprised when I say that, but also usually the don't edit videos that last longer than 5min). i said that to say that i don't program (been trying to help on other fronts), so what i'm going to say is based simply on a 'feeling': from what i got of cinelerra the 2.1 versions I used, it seems that every playback is being done by openGL, no matter what option you choose on preferences (X11, XV, etc). even though we had many machines on hand to test this when I was working closer to the estudiolivre.org 's government-funded branch, all those machines' video cards did not support openGL 2.0. so editing videos there (on 2.1) became unthinkable, because we couldn't work around this freezing issue - playback then would be very very slow (on DV videos, we only worked with DV there). we were installing jahshaka on those machines as well and jahshaka would present the very same problem - very slow playback for pretty much everything. unless, of course, if this freezing problem would happen even in case you chose X11-XV, which then would mean it was a more general issue than just involving openGL - as i said, this is just a feeling I have, based on some months watching this happening and trying to figure what that could be; but it was interesting to see jahshaka and cinelerra presenting the same problem. my (personal) video card now supports opengl 2.0 so i'll update the cv-cinelerra and jahshaka on my debian-unstable partition as soon as i have time to see if i can give any more feedback on this.
