[Feature Request] autoloader support

[wally-crunk]

A few autoloaders on the market allow the processing of a stack of discs (FIFO), like the Acronova/Datatronics Nimbie and Primera. It would be very helpful to implement/document a procedure to use autoloaders with cyanrip.

For example,

-Q | Eject CD tray if ripping has been successfully completed

It might be helpful to have a similar option Eject option if the disc is fully failed, to allow the stack to continue processing.

For example,

-Q | Eject CD tray if ripping has been successfully completed

It might be helpful to have a similar option Eject option if the disc is fully failed, to allow the stack to continue processing.

That's generally not really going to happen. It's possible that a heavily damaged disc can lock CDParanoia up.

Is -Q, plus a bash for-loop enough to handle autoloaders?

Sorry for the delay.

Is -Q, plus a bash for-loop enough to handle autoloaders?

Yes, if the discs are all good. If there is a disc that cyanrip decides is a "fail", if it aborts and does not eject the disc, then the process would stop. On a long run (for example, overnight), that is a large bummer.

In a case where CDparanoia is able to abort / report a fail to Cyanrip, and the disc isn't going to be used anymore, that's the perfect use case for a "Eject on failed" that works the same way as the "Eject on success".

[cyanreg]

cyanrip returns a non-zero error code on errors.

Basically what do you want cyanrip to do? Explain to someone who has never seen an autoloader, how they work, what they expect "eject" to mean, or how they move to other discs?

I acquired a Vinpower Cube duplicator which was relatively easy to mod into just being a disk autoloader controlled via serial port with ripping performed by cyanrip. I briefly ran into the same eject issue, that is, I had planned on using cyanrip to control eject with -Q but needed to eject on fail also so as to not stop processing the disk stack.

I was already writing the control script with luajit because I wanted to use ffi to obtain drive status info (eg. tray open or closed, disk ok etc.) so just removed the -Q option and now control the tray from the script:

-- open the tray
        ioctl(cdrom.fd, CDROM_LOCKDOOR, 0)
        ioctl(cdrom.fd, CDROMEJECT)
        assert(CDS_TRAY_OPEN == drive_status())

I've ripped around 450 disks so far and everything is working better than I'd hoped. Cyanrip has functioned flawlessly as expected but the autoloader has also been very reliable with only one odd drop that missed the ramp down to the "done" bin.

Here's a quick video of the load and unload process (the cyanrip step is omitted for brevity):
