Hi all, OpenQuicktime, I hop ethat this is the right list to get some help from, not 100% sure. I'm trying to find information about the .mov filestructure. I do want to write a little aplication in Visual Basic (oh my..) that reads the header of a .mov file, checks if it has a movie and audio track and returns some extra information like the length (in ms) of the movie, the framerate, the dimensions, the used codecs for video/audio, etc. Currently I already found something that does the sqame for .avi file (http://isengrim.rotegruetze.net/avi-info.php) I do need to use Windows, and my C++ skills are limited. So VB is my first choiche. Any help from you guys? Is there any simple documentation available about the header structure of the .mov format? (for the .avi fileformat I found this http://www.fastgraph.com/help/avi_header_format.html, please have a look) Any help is welcome, Rob |

Sorry for the long time in replying - Have I replied already ? Don't think I have - but thought I had... ! Information about the QuickTime file format is here: http://developer.apple.com/techpubs/quicktime/qtdevdocs/PDF/QTFileFormat.pdf I don't think there is a really easy way of getting basic information about a movie out - it isn't just sitting in the first few bytes of the file - that is what OpenQuicktime is for ! I know very little about VB - but do you think you could called functions in OQT compiled as a DLL ? The OQT API is documented here: http://www.openquicktime.org/docs/openquicktime/ Cheers, nick.

I know that Quicktime is, unlike .avi files, based upon an "atom"-structure. If I am correct this structure is also used for the MPEG4 file format. And thanks to the MPEG4IP project there's a lib available that has the function Mp4FileInfo which basically dumps all track information. I compiled this into a .dll which I can call from VB, works perfectly. Now I'd like to do the same thing for .Mov files but.. I can't find anything like a functionality like "MOVFileInfo" but it seems that I'll have to build such a function myself? ----- Original Message ----- From: "Nick Humfrey" <nj...@ec...> To: "Rob Coenen" <ro...@so...> Cc: <ope...@li...> Sent: Saturday, March 29, 2003 10:04 PM Subject: Re: [Openquicktime-users] .mov file info? > Sorry for the long time in replying - Have I replied already ?

There is always http://www.openquicktime.org/docs/openquicktime/Functions/=20 Functions.html#oqt_dump I don't think that's what you want tho.. A better way would be to write a function as you say to loop over the =20= video tracks, returning all the info you want, and loop over the audio =20= tracks... returning all the info you want. In fact, such a function might exist in one of the 'utils' (sample =20 code) which comes with OQT On Sunday, March 30, 2003, at 08:31 PM, Rob Coenen wrote: > I know that Quicktime is, unlike .avi files, based upon an =20 > "atom"-structure. > If I am correct this structure is also used for the MPEG4 file format. = =20 > And > thanks to the MPEG4IP project there's a lib available that has the =20 > function > Mp4FileInfo which basically dumps all track information.
