Play RAR files without extract them on SMB/NFS (RAR2FS?)

[juusso]

as i remember, here was some fstab problem (same as for rarfs too). Will check today afternoon once again.
I think problem was because rar2fs forces to mount through fstab, but this isn`t allowed on TV.
Also it is possible to run rar2fs only from SamyGO Extensions environment, native Tv`s busybox doesn`t support mount -i option and here are missing some shared libraries too.

rar2fs does not limit mounts from /etc/fstab. Rather the opposite. Actually there was a ticket raised on this some time back addressing the problem that rar2fs could not easily be called from /etc/fstab.
Also, standard mount options does not affect rar2fs, it uses its own mount routines as provided by FUSE. Most common usage is to call rar2fs from a script. Such as

Code: Select all

rar2fs <source folder> <destination folder>

or

Code: Select all

rar2fs <source RAR> <destination folder>

Eg. here is the mount command from my NAS (snippet from ps output) just to give you an idea...

Code: Select all

13076 admin      2064 S   ./rar2fs --exclude=.lock --fake-iso --seek-length=2 -o allow_other <source> <target>

But I might have misunderstood you in what was actually the problem

[juusso]

hey, thanks! Seems, i have to use right mount command. Just tried and got it properly mounted!

Code: Select all

rar2fs#rar2fs on /dtv/usb/sda/Downloads/_3D/tt type fuse (rw,nosuid,nodev,user_id=0,group_id=0,default_permissions,allow_other)

Another problem - avi file is visible in MediaPlayer, but got error about not supported video.
After this error, file dissapear from file list. Also no mount directory neither file by self could be accessible via mediaplayer.
in shell mount shows file mounted, but the mountdir is broken.

Next question is - despite description of rar2fs, i was not able to mount iso or other image files. Only rar`s.

Code: Select all

# rar2fs --exclude=.lock --fake-iso --seek-length=2 -o allow_other ./shrek.iso ./iso
rar2fs: invalid source and/or mount point

btw, required files attached (for arm (tested on B and D series TV, NAS)

Lets first check if it was properly mounted. There are issues with some fuse installations that might mess things up.
After the mount, can you do a 'ls -ld' on the mount point and post the output ?

From what I can tell your mount is done as user_id=0, that is root. Is it the root user that is accessing the folder from the MediaPlayer?

If you access the file manually from a shell, eg. using 'hexdump' does it work then?

And what version of rar2fs are you using ?

Next question is - despite description of rar2fs, i was not able to mount iso or other image files. Only rar`s.

Code: Select all

# rar2fs --exclude=.lock --fake-iso --seek-length=2 -o allow_other ./shrek.iso ./iso
rar2fs: invalid source and/or mount point

Well, maybe the description is not clear on this point. But rar2fs can not mount individual .iso files.
You can either mount a .rar file that contains a .iso file or mount a folder that contains .rar files and .iso files (or any other file for that matter).
rar2fs does not provide interpretation of the .iso file format, that is the job of the media player.

[juusso]

I`m using latest version, i think 1.14.0.

Code: Select all

 ls -ld ./test
ls: ./test: Transport endpoint is not connected

(if i proper understad your question).

After media player gave error (file format not supported), file became inaccessible nor from shell neither from mediaplayer.
From my samba mounts on NAS i see just empty mount directory.

[hasse69]

Is ./test your target folder?
Can you provide the exact command you specified when mounting to ./test ?
The error means that rar2fs/FUSE was not able to mount anything to it or crashed in the middle of doing so
If you do 'mount' you will probably see that it is mounted.
Try to do umount -f on it. And try again, but first make sure there is no stale rar2fs processes running.

Also, try to use the -f switch to rar2fs. It will start it in the foreground and then you will see if it crashes or not.

[juusso]

Code: Select all

 rar2fs --exclude=.lock --fake-iso --seek-length=2 -o allow_other ./shrek.rar ./test

Result: movie inside rar archive is visible, accessible over shell.

Code: Select all

# /bin/mount | grep rar2fs
rar2fs#rar2fs on /dtv/usb/sda/Downloads/_3D/test type fuse (rw,nosuid,nodev,user_id=0,group_id=0,default_permissions,allow_other)

Now mountpoint is ok:

Code: Select all

# ls -ld ./test
drwxrwxrwx    5 99       99           4096 Feb 14  2012 ./test

[hasse69]

Great. Ok some progress.
Now umount it and then try the -f switch I mentioned in last post and try it from the MediaPlayer.

[juusso]

Code: Select all

# umount ./test
# rar2fs --exclude=.lock --fake-iso --seek-length=2 -o allow_other ./shrek.rar ./test -f
terminate called without an active exception
Aborted
#

Aborted just after mediaplayer gave error. Mount directory dissapeared from mediaplayers list.

Code: Select all

# ls -ld ./test
ls: ./test: Transport endpoint is not connected
