HandBrakeCLI with blu-ray iso

[Eelisland]

Hello,

I'm trying to kind of automate HandBrakeCLI usage from a bash script, does HandBrakeCLI can recognize blu-ray iso or did i miss something? i'm using HandBrake rev5474 (x86_64)

Code: Select all

HandBrakeCLI --input file --scan

Code: Select all

No title found.
HandBrake has exited.

DVD isos are well recognized.

And a more off topic/general question(sorry for that), does anyone know a valid way to determine an ISO format on linux, for example running HandBrakeCLI scan on games iso can take age actually i have this as a starting point:

Code: Select all

isoinfo -d -i file

returning if it's an ISO 9660 or not.

Any suggestion welcome. thanks in advance.

HandBrake can't read iso files. You must mount the iso first. How you do this depends on which OS you run.

On linux

Code: Select all

sudo mount -o loop,dmode=0555,mode=0444,ro bd.iso /some/mount/point

dmode and mode override file permissions on the disc because I ran across some discs that had permissions set such that the dics was unreadable.

I created a script for myself that mounts any number of iso files specified on the command line in $HOME/ISO

Code: Select all

#!/bin/bash

while [ -n "$1" ]
do
	dir=${HOME}/ISO/$(basename "$1" | sed -e 's/\.iso$//')
	echo Mounting ${dir}
	mkdir -p "${dir}"
	sudo mount -o loop,dmode=0555,mode=0444,ro "$1" "${dir}"
	ERR=$?
	if [ ${ERR} -ne 0 ]
	then
		rmdir "${dir}"
		exit ${ERR}
	fi
	shift
done

and another script to unmount

Code: Select all

#!/bin/bash

while [ -n "$1" ]
do
	dir=${HOME}/ISO/$(basename "$1" | sed -e 's/\.iso$//')

	echo Unmounting ${dir}
	sudo umount "${dir}"
	rmdir "${dir}"
	shift
done

Since '*' expands before passing to scripts, unmounting all is just "umt.sh ~/ISO/*"

Hey, thanks for your feedback.

I don't want to execute the script as root, wich is needed for mounting a disc or image. I finally manage this way:

isoinfo -d -i "$iso"

iso 9660(CD-ROM is in ISO 9660 format) or (CD-ROM is NOT in ISO 9660 format) considering iso is UDF ?

dvd case

echo "" | HandBrakeCLI --input "$iso" --scan

blu-ray case

makemkvcon info iso:"$iso"

wich will return if valid title is found.
