Proxies not playing in some web clients
I’m pretty sure this is a QT problem, but I just don’t know where else to turn. Our proxies aren’t playing in the web client some of the time. It seems that they play on Macs without QT X. When I try to play them on Macs with QT X or my boss’ iPad, I get a QT logo with a question mark. In Safari, I will then get a QT error -1, which I have not been able to find info on when I google it. They do not play in Firefox, Chrome or Safari; and, as I aside, this occurs in Safari on my boss’ iPad. I’ve posted info on the proxy codec and file specs. I’m hoping that maybe the developers have seen or heard about this problem with QT before. Thanks!

try h.264 as the codec. Looks like it’s using AVC

I thought that was interesting too but I am using h.264. I set up the QT export dialog options inside CatDV to Apple’s h.264.

huh,
I’m just guessing but what happens if you pick the MPEG-4 video selection instead of the h.264? And we tend to fixate on the video. What about going to uncompressed audio instead of aac?Non-linear: all the time and nothing but.

So I tried that, didn’t seem to have any effect. However, all the videos, both the mpeg4 and the h264 were playing on one of the computers with QT X. That computer that they worked on has perian, but that couldn’t be it, every computer comes with h.264 and my boss shouldn’t have to download anything special to see them on his iPad. They still weren’t playing on one of the other computers here, even though they’re nearly identical setup (except for Perian). I swear it’s like sometimes they work, sometimes the don’t.

Browsers are maddening.
Know that we limit folks to only the latest builds of everything. (That doesn’t explain the iPad.) Have you tried the videos on an iPad or iPhone without the web client?
That’ll at least give you answers about the video itself and the browser and then you could turn it over to support.
I’d post a couple and see if they play differently or at all in just Safari on the mobile devices.

Perian can give you some really odd results. Sometimes it replaces a codec for playback and it masks the fact that you don’t have the “right” thing on the machine. I had to take it off the one MacPro I had it on.
I have a brand new iPad in my hand (well, on the desk, actually) and we’re doing some testing with our streaming services, mostly relating to security. We’ve been using h.264 MP4s for a couple of years and they’re fine on the iPads and iPhones. As a matter of fact it’s all I use now for web stuff. We use the JW player and it deals with all the calls to the different media for us.

I just tried a h264 mp4 and that didn’t have an effect; still didn’t play on that one machine. My boss is out with is iPad right now, but I’ll have him try just a video not in the browser when he gets a chance. Thanks for the continued help.

you want to put a sample up on a public folder (Dropbox?) and I’ll take a look at it? Got an iPhone there?

Hey Robb,
Since they’re really small files I just uploaded a video here. This is one of the h264 QT .mov’s that plays on some computers but not others. I personally don’t have an iPhone, I’ll see if I can borrow someone’s here.

on the iPad it wouldn’t open in VLC, but it opened, unzipped and and played in GoodReader. There wasn’t any option to open it in the native player. You might want to make sure it comes out a .MP4 instead of .MOV. And if you have a place to put it out on the web I could try it in the browser. The browser won’t deal with it when it’s zipped.
