Perian 1.2 plays only a few seconds of videos

[Melebius]

I downloaded the new Perian version 1.2. After installing, I could play only a few seconds of my AVI videos, they simply appeared as if they were as short, although I know there are about 45 minutes. So I searched the internet for version 1.1.4, downgraded Perian and it’s been OK again since then.

(P.S. Please add version 1.2 to the ticket properties here, I couldn’t choose it.)

Please post an example file or part of one (using the dd command from  http://ffmpeg.org/bugreports.html).

OK, it’s here. 1.1.4 plays 24 seconds, 1.2 only 5 seconds.

No issue here at all! You likely have some other component which is taking over parts and causing the problem. Check http://www.perian.org/#support under "Please consider removing obsolete QuickTime Components"

[Melebius]

None of the listed components installed. I have just tried it on my MacBook? where only Flip4Mac is installed, so I uninstalled it, but it didn’t help. Still just 5 seconds, on the iMac with Perian 1.1.4 and VLC on both computers OK. I just tried to downgrade Perian on the MacBook? too and it helped. Even if it was other components’ fault, should newer version bring problems?

I too have had the same issues on two machines, one a fresh install of Snow Leopard, the other an older war-beaten Macbook Pro. The exact same .avi plays fine in VLC but is limited to 5 garbled seconds in Quicktime with Perian 1.2 on both machines. Rolling back to Perian 1.1.4 solved my issues as well.

We aren't making this up :)

Uninstall either DivX or Perian and it works, but with both of them together, the video is cut to 5 secs.

The video in  http://forums.cocoaforge.com/viewtopic.php?p=123151#p123049 which exhibits this issue can be resolved with the attached patch.

This is yet another reason why AVI is a file format that needs to die!

libavformat had to read some of the packets and in some cases decode them in order to determine the parameters for the video/audio. The audio was stupidly put in the format completely lacking information so that libavcodec had to read 5 seconds of this stream to understand any of it. This resulted in a partially constructed index which Perian interpreted as the existence of an actual index.

I'm having the same problem with 1.2 and various AVI files, please consider issuing a bugfix release since this is a regression.

(In [1242]) Apply gbooker's patch fixing broken-index detection in the importer.

This allows incomplete AVI files to be fully imported again.

Closes #460
