Re: [Bf-committers] ffmpeg library update
Hi, I've done some testing with configurations. Here are some results. So, first of all i've disabled version3 and nonfree otions. First of them leads to gpl3 or higher library version, second maked libraries un-redistributable. Now libraries are gpl2 or higher. Also, i've disabled debugging symbols (--disable-debug flag). This shouldn't affect on size doe to all symbols (strip --strip-all) are stripping from blender binary. Then i've made simple config which gave exactly the same result in dependencies as ffmpeg which was used for 2.57a release. Conficuration is published in [1]. Blender binary after stripping was 43Mb. Don't think it's matetr due to linking happened against libraries which are ~1year newer, i think, and codebase of ffmpeg became larger (additional checkings, maybe architecture changed so some symbols which were unused and stripped now used and so on). Next test was with initial config from this thread with license cleaning and cleaning up flags which Peter and Joerg marked as unused and also disabled most of marked as UNSURE options. This options are related on speech (don't think this kind of audio is useful for Blender, but this libraries aren't big -- ~300Kb so could be added if they're necessery) and streaming (but dirac and schro keeped enabled -- it's algos of encoding/decoding raw videos). Configuration is published in [2]. Blender binary growed u[ to 49mb. This is also understandable, because all new dependencies (vpx, ogg, vorbis, theora, dirac, schro) are ~8mb in total. More codecs -- higher size of binary. Next step was disabled schro and dirac. Configuration posted to [3]. This saved 2mb and Blender binary became 47mb. I haven't tested with rtmp enabled because don't find stream sources b useful in Blender and this gives too much dependencies which weren't easy to solve -- some libraries came from Debian Sid environment, some from Debian Lenny, some from Lenny Backports.. Also, this adds ~2mb of Blender binary size. So, question is: do we want to support more codecs (ogg, vorbis, teora, vpx, dirac, schro) and have 8mb bigger Blender binary as we've got now?

Re: [Bf-committers] ffmpeg library update
Hi, maybe this is not the moment or not the good thread but i have a problem to import correctly pal avi video in the blender 2.57 sequencer with the 25 fps framerate. In this case, the sound is too short and of course the video in blender is unsynchronized. But if i select a custom framerate at 24 fps divided by the proportion of sound-time on the image-time, 0.96, it gives me a quite correct synchronization (one image lag in the sound time). Curiously, it displays a framerate of 25 fps. All this seems a bit absurd and silly but true. Of course, I can post all this on the bug tracker with screen captures. Regards, jms. ps : the video is a sony digital handicam one imported through win 7. ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
Re: [Bf-committers] ffmpeg library update
Also, forgot to mention. Pre-rc1 binaries were 52mb. Not sure why with the same configuration Ken had got such bigger binary -- maybe it's because of collada (not sure i've used exactly the same configuration for it). Really strange thing that even with binary 10mb bigger tham mine Ken's archive was 2-3mb smaller. Matbe it's bytes sequence issue. So, maybe enabling all that codecs aren't so big issue from binary side point of view? Sergey I. Sharybin wrote: Hi, I've done some testing with configurations. Here are some results.

Re: [Bf-committers] Camera view navigation rant
I'm talking about this for long time now but I always get this beautiful answer: We don't need that because we have fly mode. And if we really want to align camera to view, we have Ctrl+0. If you really need that (although we don't know why would you need such a thing), Blender is opensource so make a patch by your self. Buzz off. Thumbs up Daniel!

Re: [Bf-committers] Camera view navigation rant
+1 this side, While on the topic of camera view navigation, if i may just add something slightly related: not being able to zoom with ctrl+mmb while in camera view catches me out a lot. I'll often have two viewports alongside one another - one in camera view and one in 3d - while animating to the camera etc. As i use a tablet and don't have a mouse wheel, it becomes 'trickier' to focus on a certain area in both views because i can use ctrl+mmb for the 3D view but have to drop the pen and grab a second mouse/laptop-trackpad-scroll to focus in the camera view.
