* avi with three mp3 streams; muxing problem
hi guys !
1. here's the problem: i have an avi (ben hur) which i'd like to finally have three audiostreams: 1. english stream: 160kbps abr; 44,1 kHz, 16 bit stereo 2. director's commentary: 128kbps abr; 44,1 kHz, 16 bit stereo 3. german stream: 128kbps cbr; 44,1 kHz, 16 bit stereo streams were compressed using smartripper->.ac3->dannis gui(lame/azid)->mp3 for quality issues i chose abr for all three streams at first, but muxing the blank avi with these produced crappy output as to be expected due to abr (read that later ![]() ![]() so i reencoded the third stream to cbr. previously i muxed streams 1 and 2 using nandub and that worked really fine. playback is beautiful ![]() so now i thought avimux would do the job to add the third stream - now being cbr. avimux starts properly, shows the opened avi with the two already muxed streams and i can also add the third stream. but unfortunately pressing "go" it just generates a very small avi (under 1 mb) which opened in mediaplayer (using 6.4 + morgan multiple stream switcher plugin) plays back very shortly (well, what else to expect at 256orsomethinglikethatsize ![]() ![]() ![]() so i came here and searched the forum for related topics, finding these two: http://rilanparty.com/vbb/showthread.php?threadid=10047 http://rilanparty.com/vbb/showthread.php?threadid=9783 the first one's not that helpful (no replies) and slightly another problem (avimux doesn't work at all), second one mentiones using small fake avis using grahpedit: Quote:
2. so here come the questions: i; besides trying graphedit using an unmuxed mp3, (i'll try that rightaway) is there any other problem due to the way/bitrates/methods i went through you guys see and i do not ? ii; is there any known chance nandub will future muxing more than two streams in the near future ? nandos site unfortunately just gives no info on further development... maybe any one already knows something ? hope that wasn't a too-long-dumb-questions, thx for reading, ![]() other specs: all progz used are the most actual versions, expect wmp (still using 6.4) avi was done with gordian knot (latest version/divx3.11) using doom9s guide - thanks alot for the guides as well as all the soft are more than due and here they come: THX ALOT ![]() ![]() ![]() ![]() ![]()

Read this. The entry named 12/02/2001: How seeking in AVI really works, a.k.a. why your sync is off explains your problem. In fact Nandub uses a non-standard method to be able to mux vbr mp3 in avis. This works in mediaplayer, the only problem is that avis are no more workable without knowing about vbr mp3.
So you cannot mux two vbr streams in nandub and another one on avimux 'cos avimux thinks your avi is corrupted. Sorry, no luck. You have to work out other methods. I think graphedit with an external mp3 will have sync problems (not tested, just guessing) and as for nandub being able to mux more than two streams, ask it in nandub development (I don't think it's a point now, as there are more important problems and not everyone needs to mux 3 streams, sorry). |

I used MicroDVD for a while, and dropped it 'cos having audio streams sepparate from the main avi it had problems of synchronization. When you see the film from the beginning on, it works, but when you seek, god helps you to stay in sync.
