option to deinterlace during playback

Hi,

Some requests, one on-topic, two off-topic:

1) Allow users to tell Perian to deinterlace during playback in the same way they can tell VLC to do that. I realize you probably can't add any menu or preference options to the Quicktime player itself, but even having to go into System Preferences for it is fine in my opinion.

2) Allow new users registered for your Trac system to file tickets. I registered, and then couldn't find a way to create a ticket, until newticket? told me explicitly I couldn't, so I came here. Barring that, at least make it clear on your home page that new users can't file tickets.

3) Provide an email address for sending bug reports to that doesn't require subscription of some kind. Maybe you can obfuscate it somewhat if you're worried about spam.

Thanks a lot for the work on Perian, I love it!
Chris

Funny, Perian doesn't do interlaced video, this this whole idea is moot.

It is supposed to. A required plugin was missing. It was missed during the re-install after someone formatted the server. It's fixed now.

No! I've been on projects that did this, and it becomes very difficult to co-ordinate between developers. In addition, there is no means of duplicate suppression since a user has no idea if something has been reported before. The ticket system in trac is far better, and we're going to stick with that.

Ya, email like you describe is hard to handle. I like what we do now with groups and/or trac and/or the forums.

I have a video that's interlaced. It plays back with interlaced "mice teeth" in Quicktime. I just looked and it turns out it is an mp4 file, so I suppose it's not a format that Perian handles, but not being a video expert I really have no idea about these things. I ran "file" and got "TheWireS2E01.mp4: Apple QuickTime movie file (ftyp)". I thought it might have something to do with Perian, or be something that Perian can handle by intercepting the video stream and processing it somehow. If you want to see for yourself what I'm talking about, grab the first episode of The Wire Season 2 from TPB. edit: search for "The Wire Season 2 DVD Rip"

Please don't get angry, it was a request, not a demand. Plenty of projects do this, e.g. lots and lots of GNU projects with their bug-* lists that users can search. Thanks again for fixing the Trac thing.

Either the H.264 stream is interlace and thus handled by Apple's component, or the person doing the DVD rip was a complete moron and didn't pulldown the video (which happens). Either way, it's not our issue.

Alright, thanks for the info. For the record, to help people who may be reading this in the future, I found out that in Quicktime Pro there are "High Quality", "Single Field", and "Deinterlace" checkboxes if you go to Window->Show Movie Properties->Video Track->Visual Settings. Playing with these didn't completely remove the problem for me, although they may have helped a little. I also tried File->Export->Options->Size->Deinterlace Source Video and then saving it, but it was taking way way way too long so I aborted it. Oh well, back to VLC. Yay for morons.
