[vlmc-devel] [GSoC] Audio/Video sync discussion

[Paweł Goliński]

Some more questions:

4. Is fixing whole editing workflow a part of this project? As it stands now, I can’t save/export/preview any project on my computer (and AFAIK its the way VLMC behaves everywhere), and I see the implementation of audio/video sync as encapsulated clock mechanism, that would eventually connect somewhere (renderer? workflow?). The problem is, if by the end of clock implementation, all underlying mechanisms doesn’t work properly-ish it would be hard to connect it anywhere. And repairing/refactoring everything sounds like a different project…

5. If it’s [question 4] a part of the project, would it be ok if the audio/video sync mechanism is not fully implemented by the end of GSoC? I assume that it would take A LOT of time to make VLMC usable, and the audio/sync between multiple video sources is another non-trivial problem. If it’s not a part of the project, will it be implemented before, let’s say, half of the GSoC work period? If not, what is the expected result of the GSoC project? (Again, to connect a clock to some mechanism, this mechanism should already work…)

Is it a problem with the timeline, that all streams injected into timeline are out of sync between each other, or what? (VLMC is pretty much non-functional on my computer when it comes to using any feature connected to video editing, so I can’t check this myself).
