[CinCV] Re: Cinelerra CinCV merge request / Cin2.1.5CV
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hello Hannes, I've received the following answer from aballier, explaining the libavutil50 and x264 patches by gentoo. In my opinion both changes are fully justified, and _now_ as well sufficiently explained. So what is currently still pending / not merged yet (that should be included in Cin2.1.5CV)? With best regards, Simeon - Original Message Subject: Re: gentoo's cinelerra patches Date: Thu, 28 Oct 2010 11:00:43 -0300 From: Alexis Ballier Organization: Gentoo To: Simeon Völkel Hi, > we are currently working on Cin2.1.5CV and now collecting patches from > distributions to be included in the next release.

Anyway, about these two patches, its been so long that I don't remember but let's try. in any case, you can see the cvs log here: http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/media- video/cinelerra/files/ > > cinelerra-libavutil50.patch > > This patch seems to be quite destructive, as it replaces RGBA with RGB > color models. Is that really a proper solution or just a workaround that > does not mind loosing the alpha channel? Could you please explain this > patch? cvs log says: Fix build with libavutil 50 by not using pixel formats that have been deprecated for years. libavutil/pixfmt.h says: * PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA * color is put together as: * (A << 24) | (R << 16) | (G << 8) | B * This is stored as BGRA on little-endian CPU architectures and ARGB on * big-endian CPUs. #define PIX_FMT_RGB32 PIX_FMT_NE(ARGB, BGRA) #define PIX_FMT_RGB32_1 PIX_FMT_NE(RGBA, ABGR) #define PIX_FMT_BGR32 PIX_FMT_NE(ABGR, RGBA) #define PIX_FMT_BGR32_1 PIX_FMT_NE(BGRA, ARGB) so at least the remark of it being destructive is wrong iirc the only thing this patch changed is the name: the two pixel formats were #defined one onto the other but with libavutil 50, the one cinelerra was using was gone. You'll have to check libavutil/pixfmt.h svn history in ffmpeg svn if you want a 100% accurate answer there I'm afraid. > > cinelerra-x264.patch > > What does this patch solve? 9 +#if X264_BUILD >= 76 10 + int size = nals[i].i_payload; 11 + memcpy(codec->work_buffer + codec->buffer_size, nals[i].p_payload, nals[i].i_payload); 12 +#else I guess you can infer the obvious answer :) Again, don't ask me to explain more: it's been so long that I forgot.

Branch sv/gentoo-fixes shows what I have queed so far, but I think I'm not sure whether the tip one (the gentoo ffmpeg fix) is good.

[CinCV] getting started witn HD
I am just getting started with Cinelerra CV and started to render a test video to 1920x1180. It looked like the rendering hung (the CPU load went to almost nothing). I tried to close Cinelerra but it warned me that rendering cannot be interrupted. I killed it at the command line and thought I was prpared to accept the mess I made for myself. I ended up deleting ~/.bcast/ and the project xml files and starting over. But now when I add content to the project, the clips video play at double speed and the audio at normal speed and the clips art truncated at about half way. I am using the same video files added to my resources folder. Any ideas? My files were converted with ffmpeg with this command: ffmpeg -y -threads 4 -i INFILT.MTS -b 220M -vcodec dnxhd -acodec pcm_s16be OUTFILE.mov I have tried various format settings but it looks like it does not affect this problem.

Re: [CinCV] getting started witn HD
I found that if I right click on the resource, then click info, then change the frame rate from 59.94 to 29.97 it plays right. I never did this the firt time around. Hmmm...

Re: [CinCV] getting started witn HD
So I got past that problem, tried to render, and it hung again.
