SMV-video support

It would be nice to be able to watch SNES-speedruns from http://TASvideos.org with ZSNES, but they're using the evil Snes9X and its SMV-format. I would code the support for SMV myself if I wasn't so lazy and knew how to code stuff with assembly. Since it's open source, it might be easy.

SMV would probably not be supported... however, you probably haven't checked out this thread: http://board.zsnes.com/phpBB2/viewtopic.php?t=3103

Why would you fathom that this would ever be possible with an Snes9x movie? However you can watch videos from TAS Videos if they are ZSNES movies.

You're not going to get any help if you insult our hard work.

Who said it had to be done in assembly? Furthermore adding SMV support won't allow you to playback the movies anyway.

The end result is just a series of keypresses, so it should be possible to create a converter for movies that start from Reset.

But even different builds of the same emulator can lead to desyncs, I doubt the converted movies would not desync, since the currently playback is based on frames and not on controller port accesses.

Wouldn't make much of a difference for sync between versions and emulators.

what's left before zsnes gets adopted or accepted at bisqwit's? i'm assuming there are still some desync issues. is there anything else?

That simply would be the most important issue.

All that is waiting for is a release.

Afaik desyncing occurs when the wrong frame gets the right input (or vice versa). So if the input wouldn't be bound to the frame index...

So you assume that somehow if input comes in when requested instead of by frame it'll somehow request and manage said input 100% same between emulators and revisions?

Yeah. I'm assuming that different builds might request it at different times, but won't skip it. In that case emulation would be broken anyway.
