Your last response to me made me check into my archives. This is what I found:
1. I last attempted to use .flv files a couple of years ago -- that's why I needed to refresh my memory. I rarely use video, so it's not something I keep at the forefront of my memory, and unlike others in this group, I like to keep my needs simple.
2. The flv format (like several other graphic or video formats) is not supported by Opus.
3. To give me flexibility in my choice of formats, I have installed appropriate file conversion software that lets me convert unsupported files to a format that is supported by Opus.
4. As you are no doubt aware, using and converting any format, particularly video formats, can be tricky because of the variety of codecs which might have been used to encode the file. For that reason I ensure that I have a lot of different codes installed on my computer. The only requirement is that the codec costs me nothing.
5. I currently use a package called WM Converter which is available from
http://www.wmrecorderpro.com. It is free -- my favourite price!
Today, I took a largish flv file (57MB) and tried to convert it to MPG, but that failed. Next I tried to convert the file to AVI and this worked perfectly.
But bear in mind that I might have different codecs to what you have on your system.
WM Converter can convert both ways between several formats.
It might be worth your while downloading a copy and experimenting.
Hope this helps
