Thread: [Libquicktime-devel] Timecode Media Information Atom : "Flags" field should be zero ?

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi.

I've come across a potential problem with how the the Timecode Media 
Information Atom (tcmi) is initialised in libquicktime.

According to the QuickTime File Format Specification on the Apple 
developer website the "Flags" field of this atom should be set to [0].

https://developer.apple.com/library/mac/documentation/quicktime/qtff/QTFFChap3/qtff3.html

However when creating a new QuickTime file with libquicktime the field 
is always initialised to [1] - and there appears to be no way to change 
it via the public API.
The field is initialised in this source file:

     libquicktime-1.2.4/src/tcmi.c : line 30

Unfortunately I couldn't find a more detailed description of what the 
"Flags" field actually does - but it appears to be connected to whether 
Apples QuicktimePlayer7 application draws a black band with the timecode 
printed on it over the bottom of the image.

Here's how I noticed the problem:

When I tried to open a Quicktime movie that was encoded (with a timecode 
track) using libquicktime and the "ffmpeg_dnxhd" codec (avdn) in 
QuicktimePlayer7 on OSX (Mavericks) the application would segfault.
 From the stacktrace (appended below) it appears that the segfault 
occurred in the "AvidAVdnCodec" plugin in a function called 
"AVID_DrawBand()" - which sounds suspiciously like a function that would 
draw the timecode overlay - and which may be potentially buggy.

Since this is the official Avid DNxHD plugin for Quicktime on OSX 
there's not that much we can do about it as all our target devices would 
have it installed and which are mainly beyond our control.

Because of this problem, together with the fact the Apple recommends the 
value for this field to be set to [0] anyway, I would like to suggest 
changing the initial value for this field in the libquicktime source to 
[0] as well.

Of course we can change it in our build - but ideally it would be merged 
up-stream.

Please let me know if that would present a problem or maybe why the 
"Flags" field would have been initialised with [1] in the first place.

Thank you and kind regards,

Matthias
