MP4CopyTrack freezes when track edit applied #137

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
We really need mp4 clipping to an external file.  I found a sample application 
online and created a simple test app from it (attached).

In the test app, for each track MP4CopyTrack() is called with 'true' to use the 
track edit added to the track.  The test app freezes the first time this 
function is called.  It does not freeze if the flag is set to 'false'.

I'm assuming that there is an error in mp4v2.  If not then I don't know what 
I'm doing wrong.  I pass is 1 and 10 for the start and duration times.

Test App usage:
<start-time> <duration> <input mp4 file-name> <output mp4 file-name>

I'm using mp4v2-2.0.0.tar.bz2 on Windows.  There were some Windows-only files 
missing from the distribution.  I copied the missing files from the trunk.

what's the callstack at the point the test app freezes?
