codec - Writing QuickTime files manually -


in app i'm working on, there's avirecord class manually write avi headers , jpeg frames video files. .avi files mjpeg codec, according media player (using klite codec pack).

my question is: avi compressed or uncompressed? because file size sum of jpeg frames.

can write similar code produce .mov file (quicktime format)? similar mean: writing headers file, putting each frames manually files.

the app working on supposed save jpeg stream ip cam , save under quicktime format.

most file formats avi, mov not compress video , audio bitstreams present in them. file formats used store video , audio decodeable units associated metadata timestamps. when add jpegs avi file, not compressed further.

you can create mov file mjpeg video, similar way have been able create avi file mjpeg video. need creator mov (similar 1 have avi).

mov file format has been specified apple. version of format available @ http://developer.apple.com/standards/qtff-2001.pdf
