help:multitrack a/v in mp4

[uray]

using YAMB 1.3.2 , i've tried :
"MP4Box.exe" -add "v.mp4#1:name=track 1" -add "a.aac:name=track 1" -add "v2.mp4#1:name=track 2" -add "a2.aac:name=track 2" -keepsys "out.mp4"

but seems not work, MPC showing error, and another player don't recognize track 2... any clue how to mux multitrack movie on mp4 ? (and playable on MPC)

I'm pretty sure that yamb didn't use this to create your file...or you have edited manually your cmd line.

no it's YAMB produce it, i'm only remove directory before filename to shorten it before post to here...

v.mp4 is contain video only
a.aac is audio

v2.mp4 is video that suppose to be on track 2 (play after track 1 done)
a2.aac is audio for v2 video

then i tried this, mux v.mp4 and a.aac = av.mp4 first then mux v2.mp4 and a2.aac = av2.mp4, now add both movie to YAMB :
"MP4Box.exe" -add "av.mp4:name=track 1" -add "av2.mp4:name=track 2"

still won't work, MPC produce error and only play track 1, so with nero showtime only recognize first track

are you trying to mux multiple video streams in the .mp4? if yes, mpc doesnt handle video switching...

edit:
if you want to merge the a/v streams use -cat

ooh i see that, do you know what player support video switching? it seems nero showtime doesn't support too...

if i use cat (merge), is it ok if both have different resolution,AR,bitrate and other property?

ooh i see that, do you know what player support video switching? it seems nero showtime doesn't support too...you can do it in mpc when you disable mpcs internal mp4 splitter and install the haali media splitter instead

quicktime can also do video stream switching

if i use cat (merge), is it ok if both have different resolution,AR,bitrate and other property? they need to have the same resolution and ar (and other codec settings influencing the bitstream). bitrate doesnt matter
