I want to add some tags (date, author...etc.) to avi file. I try transcode, and I read manual many times, but I realy dont understand. I read avi_comments example, and still dont know what command to use in trnacode command line to add comment. I see that I can use file in doc avi_comments, and I try that as avi_comments argument, but nothing. Does somebody know how to add avi comment with transcode, and if not, is there any other tool ?

It seems easy enough to me. You simply create a taginfo text file with the values you want, as explained in avi_comments.txt. Something like this:

And feed it into transcode along with the avi file you want to tag:

And the result should be a tagged avi. I notice, however, that for some reason xine doesn't seem to want to recognize the tags. But I can get them with some cli tools such as avitype and the --identify flag of mplayer.

I see from the man page that mencoder also has an -info option for adding tags to an avi file, but I haven't tried it myself. It seems to be simpler than transcode's version, but more limited in the kind of tags it can create. It only covers some of the possible entry options.

I still have some problems...
When I try:

I get this:

And when I try without p3, like this:

I get this:

OH, I think I made mistake, because I use lowercas p. Now I try -P3, and it works, than I use
and I succesfully read all tags. Thanks a lot.

Glad it worked for you.

Just for your info the "-P3" flag is pass-through for both video and audio; basically we're telling transcode to copy the data as-is from the old .avi file into the new one. You generally won't use that tag when you're trancoding from one format to another.
