Hi guys, one thing that was long due is the native AVI DV support. Most wondoze programs can write "DV format", where the actual DV frames are inside of an AVI container (with or without an extra audio track). dvgrab also writes this sort of file. As far as I can tell this has no advantage over raw DV files, but at this point I do all my capturing on windoze, since kino capturing is constantly crashing on me and with just using dvgrab I cannot see what I am actually capturing. So I want to be able to read my AVI DV files created on windows. This is done and works very nicely. It is committed to the V00-03-devel branch.
If anyone is testing this, I would like to hear if it's working. In principle, since I had to write a almost complete AVI parser, it is now possible to add native piave codecs for audio/video inside AVI for piave (e.g. with libavcoded of ffmpeg). Also I did some further work on enix integration (which would provide it's own container parsers for AVI and MPEG etc.), and to tell you the truth, I think I was right from the beginning. Editing a video sequence in compresses divx files is completely stupid. I think even mpeg might be a problem. It's just not possible to do fast searches and move backwards in a file. Right now, everything is so slow, it's by _far_ unusable. If anything else, it will at least take a lot of work to optimise intelligent caching of mpeg-chunks inbetween I frames. There is just no single video library for linux which does that. They are all coded with fast replay in mind, but not for editing, there it's necessary to cache the decoded frames. If DV wouldn't be limited to PAL or NTSC resolution, I would strongly vote for just converting averything you want to edit to DV and then edit it in DV. Who cares about disk space these days. I think I would rather like to start coding some functionality for capturing. Since I would like to play around with Qt anyway, I can also implement a little dialog in kdenlive.
