Using AVFoundation Player fails in LC 6.7.6

[panagiotis merakos]

Hi Tiemo,


The command 'start player myPlayer' should work. I just tested with LC
6.7.6, adding a new player and executing "start player 1" from the msg box
works as expected. What is the format/codec of the video file you want to
play? It may be the case that the particular video format or codec is not
supported by AVFoundation. The .mov file format *is* supported, but not for
all codecs. Please see pages 26-29 of the following pdf for some codecs
that *don't* work:

Currently, if the OS X version >= 10.8 then LiveCode uses AVFoundation
player, thus the global variable "dontUseQT" is set to true. This means
that functions like qtversion(), qteffects() etc will return 0.0 or empty.
However, if you "set the dontUseQT to false" (before creating the player),
then you force LiveCode to use the old QT player even if the OS X version
is >= 10.8. In that way you can still use the QT-related functions.



Hope this helps,

Panos
