"File does not contain a video track" error on every file I try (avi/m4v/wmv/mpg) #9

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Drag video file in to the Skreenics window.

What is the expected output? What do you see instead?
I expect Skreenics to do it's thing, but I get the following error every time:
"File does not contain a video track"

What version of the product are you using? On what operating system?
1.0.1(1)

Please provide any additional information below.
I'm on a G5 (PPC) running 10.5.8

What decoder does Skreenics use? Quicktime? All of the files I'm trying work 
fine in Quicktime and VLC.

Thanks in advance!

Hi!

I'm sorry, but the program has been totally untested on 10.5, even though I did 
compile it with 10.5 settings.

Just like you guessed, it's using Quicktime (QTKit.framework), which is why I 
am not sure why it's doing that...

Bummer - there must be some "secret sauce" that's missing to get it working in 
10.5. :) Thanks for the reply!

Probably. Feel free to look into it:

ion.m#140
> There you will have Step 0 + Step 1 that are all that is necessary to open a 
QTMovie + ask the framework if it does contain a movie track :-)

Maybe 10.5 doesn't return QTMediaTypeVideo or QTMediaTypeMPEG elements, for 
example.

FWIW, I ran into this problem on 10.5.8/Intel *if I ran the program in 32-bit 
mode* (which I do habitually since by default almost nothing else runs 64-bit 
on 10.5).  

However, if I unchecked the "Open in 32 Bit Mode" checkbox, video tracks were 
detected properly.

I don't know if that's an option for the OP on PPC.  If I have some time, I 
might try to debug.

I was getting this on many files.  I then changed the extensions of all my m4v 
file to mp4 and that cleared it up so far.
