Hi, All,
Hope I'm writing to a correct list...
It's an obvious bug, which occurs when I use -vcodec copy option for
FLV conversion to MOV container. My FLV file has Sorenson H263 video
(i.e. FLV video codec #2). It should be placed into MOV container with
"FLV1" FOURCC signature, but it is placed as "H263" FOURCC, which is
not recognized by QT player. This was tested on mac OS X 10.5 with QT
Pro v. 7.7
Can it be fixed? I can update fourcc manually within mov file and it
starts to work correctly. So, the problem is just in the incorrect
fourcc, but not in the codec itself.
Here is FFMPEG build data:

mov muxer is not enabled explicitly here, but it is enabled
automatically as we enable ipod muxer.
-Thanks.
