Odd behavior with m4v files on AppleTV

[jbuzbee]

Beta 6 on AppleTV 2.01. I recently Handbrake-ripped a few DVDs using the pre-set AppleTV settings in order to get the new enhanced audio support, but I am seeing some odd behavior from Sapphire when I attempt to play them back. The first odd thing I noticed is that when I navigate to the movie in the virtual All Movies menu, the "size" field shows 32K when in reality the files are around 2.4 Gig. The files are on a network-mounted drive (I've tried both NFS and SMB with the same behavior). When I select the movie, I get a quick "Loading DVD.." display and then I get dumped back to the menu or the Finder crashes.

The really odd thing I see is that when I navigate to one of the movies directly, i.e. not through the Virtual directory, Sapphire will play the files correctly. And when I stop, the movie, the display shows all of the correct A/V data including the proper size. But when I go back to the movie through the Virtual menu, the A/V data is still minimal with the 32K size and attempting to play fails.

I've tried clearing the metadata, turning AC3 passthrough on and off and renaming a problematic file with no change in behavior. Looking at the plist data, I see that the size is negative, but this appears to be the case with a number of my movies. Playing the files back in Quicktime on my MacBook? is successful as is playing the files with ATVFiles on the AppleTV.

It asked for the console as well. In addition, your crash log is very suspicious; because it contains calls which don't follow any chain in the code.

Here's the console output from a new crash

I don't know why the traceback would look suspect. I've attached a new, complete log from this new crash.

Did anything precede the crash, such as exceptions. This is explicitly mentioned in BugReporting.

Again, your crashlog is suspect. itemSelected: does not call _processNextTransaction.

A tail-f on the log while browsing around shows nothing unusual (e.g. exceptions) until the crashes, as detailed above, occur. These crashes only occur on m4v files. Also note that when I can get a m4v to play, I get odd behavior as well. I see my receiver 5.1 indicators flash as if it's trying to lock-on, but then it rarely (never?) does. Sometimes I just get stereo, other times I get no sound at all. I can play these properly, with 5.1, on the AppleTV using ATVFiles, but I much prefer Sapphire's metadata-organized interface.

Again, your crashlog is suspect. itemSelected: does not call _processNextTransaction.

I'm using a binary version downloaded from nanopi.net, so I don't have any explanation for differences. Maybe I just need to re-install.

After a removal, re-download and re-install as documented in the nanopi.net instructions, I get the same behavior.

I think you're misinterpreting what I am saying. When I say the log is suspect, I mean that it cannot be trusted to provide reliable data, not that you did something wrong. This is typical of a memory issue. Since Sapphire is a plugin, there is no easy way to narrow down the real issue.

I can tell you, ATV 2.0.x is unstable. It crashes in random places, completely unrelated to the plugin used. I have crashlogs which show bugs in the graphics processing for Quicktime and the like.
