Hi!
I'm involved in a project where I need to create Quicktime movie files from scratch, byte by byte. That is, I have a video stream coming in from a hardware device in DV format, but I need to wrap it up with Quicktime atoms so that end-users (and applications like Final Cut Pro) will see the video as a normal QT movie file.
I've done this successfully with the video, creating a 'vide' track with a 'dvc ' sample description. But I'm having some difficulty formulating a 'soun' track with a 'dvca' sample description. I haven't been able to find any documentation describing the codec-specific parameters (if any) that should be placed in the 'stsd' container.
I have some sample QT movie files, but they all use the 'twos' format (k16BitBigEndianFormat) for the sound track, pointing at a separate 'mdat'; I want to use 'dvca' (kDVAudioFormat) pointing at the same 'mdat' as the 'dvc '.
I'm working in an embedded device with no operating system, so I can't do this by calling the Quicktime API. This has run me into some blank walls in the documentation for the Quicktime file format (QTFF.pdf) and related documentation on codecs. Some relevant documentation or sample files would be very much appreciated.
Or, if you have experience with the guts of these things, have the QT tools and are not afraid to use them, and are willing to do some consulting to get me past some of these hurdles, I'd love to hear from you off list. In addition to knowing how to learn these things, you could help me by creating sample files to work with and evaluating my output files at a technical level deeper than just "yeah, it plays in the QT player".
