I recently heard the Power-DivX crew working on a new (enhanced ?!) (A)udio(V)ideo(I)nterleaved format. As it obviously will be an appreciated improvement ,so what are so far the limitations of the former AVI ?
From my point of view it's already a quite abusable format with a lot of different audio formats being admitted. How does the AV-interleaving work anyway ?
as follows? :
block 1: {video data | audio data | synch data}
block 2: {video data | audio data | synch data}
block 3: ~ ~ ~
block size ? adjustable ?
The only problems I got is in playback of DivX with AC3, but I think it is due to weak heart failure (CPU @667 MHz combined with choky TNT2 pro graphiccard) - and believe me I consulted a lot of fiendly guides besides Doom9 to fix it... no go...the video pb isn't smooth, but in synch, while pb with mp3-VBR is smooth as grease.
Second restriction - and I think I#m not alone - is damn playback of a 2nd audio stream as an external file source. If played from the beginning of the whole movie (if multi-CD which it is always in my case) it stays synch, but if I try to seek into the movie it lacks behind both in 'forward' and 'chapter jump', for example when using such feature in Micro-DVD-Player.
To come back to my initial question: is the latter issue due to insufficient synch management with audio files originally not intended to be implemented such as VBR-MP3, which I always use for both streams ??
I know it's alot asking at once, but it jammed up in my head.
PLEASE ME ??
