Comment (by saste):

 Replying to [comment:8 RCAB]:
 > I have 1 Disc with 8 clips for testing XDCAM EX files with my scripts
 which transcode by using ffmpeg the files into lowres quicktime format but
 I also need the TIMECODE for use in AVID.
 > I use ffprobe to analyze the incoming files.
 > All videofiles have a seperate XML file.
 > But the basic part of the XML file is also embedded in the MP4 files,
 always at the end of the file.
 > ffprobe is now telling me that the TIMECODE: 00:00:00:00
 > It would be nice if I could read the TIMECODE directly from the MP4 file
 instead of the seperate XML file.

 I see but what I'm asking is if you're aware of any spec document
 dictating how such metadata should be retrieved, or if this is specific to
 the application you're using to create and read the file (in other words,
 why is the program not using the usual way to mark metadata?). That said,
 it would be in theory possible to read the information from the file even
 if highly unpractical since it is stored at the end of the file, and would
 require proper XML parsing (and thus require a dependency on an XML
 parsing library).
