Well it’s still the same problem. I mean, it’s likely piracy to copy the public lib’s disc to begin with, even if just for a moment. From there, if I want to share it w/others I still need to be able to exit the library with the data before they close. So it’d still be a matter of transcoding as a distinctly separate step.

What’s the point of spending a day compressing something that I only need to watch once?

If I pop into the public library and start a ripping process using Handbrake, the library will close for the day before the job is complete for a single title. I could check-out the media, but there are trade-offs:

• no one else can access the disc while you have it out
• some libraries charge a fee for media check-outs
• privacy (I avoid netflix & the like to prevent making a record in a DB of everything I do; checking out a movie still gets into a DB)
• libraries tend to have limits on the number of media discs you can have out at a given moment
• checking out a dozen DVDs will take a dozen days to transcode, which becomes a race condition with the due date
• probably a notable cost in electricity, at least on my old hardware

Wow, thanks for the research and effort! I will be taking your approach for sure.

I’ll have a brief look but I doubt ffmpeg would know about DVD CSS encryption.
