[Bug 349011] [NEW] DeVeDe bitrate calculation for DVD iso is incorrect

[Uri Stamonov]

Public bug reported:

Binary package hint: devede

Ubuntu Studio 8.10 x86_64

Linux xxx 2.6.27-14-generic #1 SMP Fri Mar 13 19:54:51 UTC 2009 x86_64

gregor at mymachine:~$ apt-cache policy devede
devede:
  Installed: 3.11-0ubuntu1
  Candidate: 3.11-0ubuntu1
  Version table:

Expected:

When creating a Video DVD and clicking "adjust disk usage" the video and
audio rates are adjusted up to the maximum possible to create a 4.7GB
DVD image

Actual Result

When creating a Video DVD and clicking "adjust disk usage", the video
and audio rates are reduced and an image smaller than 4.7GB is created,
usually around 2GB

Steps to reproduce:

1. Open DeVeDe
2. Select "Video DVD", click ok
3. Add Files / Titles at maximum video and audio rates
4. Click "adjust disk usage"
5. Click "forward" and create the image

I suspect that the mechanism which works out the size of the resulting
image is broken, as it is also possible to add titles and files way in
excess of the size reported in DeVeDe, and the actual iso file created
is still smaller than 4.7GB.

For example: 4x30 min avi clips at max bitrates show an "estimated
length" of 3486 MB, and the output is reported in the Disc Usage bar as
130% of a 4.7 GB DVD. Both these figures are way too high.

Hope this info helps

Uri
