Hi,

Thoughts, comments, questions, proposals, even flames are warmly welcome.
I have a couple of requests, could perhaps even be considered bugs, but I don't think so. In order to explain this I have to make some comparison with what I do on Windows and what I try to do with transcode via DVD::rip. On Windows I use a package called Gordian Knots which is basically a glue between ripper (dvdrip), frame server (DGIndex) and encoder (Nandub). The ripping part, ie copying VOBs to disc decrypted, works very well in transcode. The frame server is what extracts the sound. I always just mux in the ac3 sound regardless how many channels there are in the VOB so its pure demuxing down to a file.
What DGindex can do though that I haven't found in transcode is to find out whether the source is interlaced or progressive. I don't know if there is any harm in deinterlacing progressive material or not but it would be nice to able to skip that process if its not needed.
Another thing DGindex does, which is very vauluable, is detecting any AV skew and it does that down to the millisecond. I have had DVDs where the video was 216 ms ahead of the sound and DGindex recorded that info in the file name of the ac3 file. So when Nandub muxes in the sound it shifts the video backward or forward depending on that information. I haven't found anyway of doing this in transcode.
If I only could get that functionallity in transcode I could retire my Windows box as encoding DVDs to xvid is the only thing I'm using it for.
I would also like to add that I don't really know what the frame server does. I can guess that it creates a file where it records which video frame goes with which audio frame or something like that. A file I haven't seen in transcode so what I'm asking for might not even be possible with the current architecture.
Thanks for transcode though, a very good piece of software. Regards, Johan
