besweet and vobs...

[chi]

hi dspguru and anyone else...

i'm using besweet 0.93, ac3-processing works fine but when using vob for input, the output is still choppy... just wanted to let you know.

and a little question:
sometimes i get some output like this in my dos box:

[00:48:13:120] | MP3 Max bitrate : 320
[00:48:13:120] | Channels Mode : Joint Stereo
[00:48:13:120] | Error Protection: No
[00:48:13:120] +---------------------
[01:23:36.586] W6: Downmix overflow (+1.4dB). <-----------
[01:23:36.816] W6: Downmix overflow (+1.2dB). <-----------
[01:23:36.826] W6: Downmix overflow (+1.4dB) <-----------
[01:13:03:296] +------- BeSweet -----
[01:13:03:296] | Input : h:\fsgfs\vts_01_4.vob
[01:13:03:296] | Output: e:\smilla\test.mp3
[01:13:03:296] | RIFF header will be added
[01:13:03:296] | Substream ID: 0x80

why is there still overflow although i used -g max? i guess it's no problem, just want to be informed.

my cmdline:
besweet -core( -input h:\fsgfs\vts_01.lst -output e:\smilla\test.mp3 -substream 0x80 -wavmp3 )
-azid( -s stereo -n 1 -c normal -L -3db -g max ) -ssrc( ) -boost( /disable ) -lame( -h --abr 112 )

hi chi !!!
the choppy output should be fixed now. read other thread (http://rilanparty.com/vbb/showthread.php?s=&threadid=12433).
about the vob problems - i don't know, bbDMUX is giving me hard time :(, i don't think this overflow ever occurs on pure AC3 streams.
i might switch bbDMUX with vSTRIP in future versions..

thx dspguru, i'll give you feedback

You have overflows because you use .lst file and besweet only do -g max on first vob (for this the overflow come only on other vobs- not the first in list...)

damjang, are you sure? when i look at the timemarks it scans all vbs for max gain... i think, not too sure. i'll check this later....

[DSPguru]

damjang is probably right, if the overflow occurs on the second/third/.. vob, that's the exact reason.
