Lost video

[Ian Davidson]

Hi Tim,

No luck yet.

I did a number of tests and put the results in the attached document 
(which has a Table of Contents to aid finding particular sections). The 
document contains the complete script I used each time - partly for 
completeness and partly so I don't lose anything.

I did the script as detailed below with various levels of debug.  I 
removed the Audio branch, and I included videorate and audiorate.

Without videorate/audiorate I consistently got an AVI file where the 
audio was the complete length and the video was very short.  With both 
videorate and audiorate included, I got a very short AVI file and I 
notice that audiorate repeatedly reported that it was dropping 441 
samples (which was all the samples it had apparently received).

I am prepared to believe that I have done something stupid - but I 
suspect that it is not all my fault!

Ian
