Can't access DVD

[ffeingol]

My docker compose file is as follows:

handbrake:
    container_name: handbrake
    image: jlesage/handbrake
    ports:
      - "5800:5800"
    volumes:
      - "$USERDIR/handbrake:/config:rw"
      - "/media/video:/storage:ro"
      - "$USERDIR/handbrakewatch:/watch:rw"
      - "/media/video:/output:rw"
    environment:
      - TZ=$TZ
      - GROUP_ID=$PGID
      - USER_ID=$PUID
      - SUP_GROUP_IDS=24
    devices:
      - /dev/sr0
      - /dev/dvd
      - /dev/dri
    restart: unless-stopped

From the logs, /dev/sr0 is recognized. The problem is when I navigate to /dev/ I only see folder and I don't see the sr0 or dvd drvice. I confirmed they are physically there by entering the container.

Thanks!

I have the same issue. The docker compose file is essentially the same as the OP's.

On the host I have

dan@dppr:~/handbrake$ ls -la /dev/sr0
brw-rw---- 1 root cdrom 11, 0 16. Dez 15:34 /dev/sr0
dan@dppr:~/handbrake$ lsscsi | grep dvd
[1:0:0:0]    cd/dvd  PIONEER  DVD-RW DVRTD11RS 1.01  /dev/sr0

In the container I see:

...:/tmp# ls -la /dev/sr0
brw-rw---- 1 root grp24 11, 0 Dec 16 20:35 /dev/sr0
...:/tmp# lsscsi | grep dvd
[1:0:0:0]    cd/dvd  PIONEER  DVD-RW DVRTD11RS 1.01  /dev/sr0 
...:/tmp# groups app
app grp24 grp44

Any idea what else to try to access the DVD drive from Handbrake?

[ffeingol]

It does not make a lot of sense, but adding

- CONTAINER_DEBUG=1

In the environment: section got it working for me.

[dpprdan]

Unfortunately this does not make it work in my case.
FWIW I don't have a /dev/dvd device on my host (and hence in the docker compose file).

My docker compose file is as follows:

handbrake:
    container_name: handbrake
    image: jlesage/handbrake
    ports:
      - "5800:5800"
    volumes:
      - "$USERDIR/handbrake:/config:rw"
      - "/media/video:/storage:ro"
      - "$USERDIR/handbrakewatch:/watch:rw"
      - "/media/video:/output:rw"
    environment:
      - TZ=$TZ
      - GROUP_ID=$PGID
      - USER_ID=$PUID
      - SUP_GROUP_IDS=24
    devices:
      - /dev/sr0
      - /dev/dvd
      - /dev/dri
    restart: unless-stopped

From the logs, /dev/sr0 is recognized. The problem is when I navigate to /dev/ I only see folder and I don't see the sr0 or dvd drvice. I confirmed they are physically there by entering the container.

Thanks!

Your missing a device that you need to make available to the container.
install

sudo apt install lsscsi

run

sudo lsscsi -g

you should get a result like this

[0:0:0:0]    disk    ATA      TEAM T253X2001T  0A0   /dev/sda   /dev/sg0 
[1:0:0:0]    cd/dvd  PLDS     DVD+-RW DU-8A4SH QD13  /dev/sr0   /dev/sg1 

you need to keep /dev/sr0 and add /dev/sgX (or whatever the corresponding sg to your optical drive.)

[jlesage]

I also reproduced the problem where HandBrake is not showing optical drive's device. Something changed in HandBrake that broke this functionality.

[Dvalin21]

One of the things I had to do also is mount /media/user/ (im running linux mint)
This then showed the dvd in handbrake, however, once you eject the dvd and reinsert, you would get permissions denied.

[jlesage]

What is the content of /media/user/ ? I guess this is where the host automatically mount the dvd ?

[Dvalin21]

Yes

[dpprdan]

Not sure whether this is the cause or a symptom or whether this is obvious to y'all, but this is what I found out digging around:

The last version to reliably show the /dev/sr0 device is v2023.11.2 (Handbrake v1.6.1). Note that it shows "All" in the filetype selector (and not "All files").

If you select the sr0 in v2023.11.2 (or earlier), close the container and then start a later container up until v2023.12.1 (Handbrake v1.7.1), you can still see sr0 in the "Open Source" pane. Note that now the filetype selector does not show anything.
("Trash" is also gone and "Detected DVD device" changed to "Single Title". All these changes happened in Handbrake v1.7.0 apparently).

If you select "All files" (sic!) there, sr0 and all other filetypes that are not proper files or folders are filtered away.

Starting with v2023.12.2 (HandBrake v1.7.2), I can never see sr0 in /dev/, no matter if I selected it in an earlier version.

So AFAICT the issue is that Openbox (?) does not show any file types that are not proper files or folders (i.e. devices, sockets, pipes, etc.). Would it be possible to bring them back there, @jlesage?

All of the above only requires devices: /dev/sr0 in the docker compose file.

As an aside: Mounting the DVD drive via the Docker compose file (volume: "/mnt/cdrom:/mnt/cdrom:ro") worked only very unreliably for me (i.e. I won't read a whole DVD). I also tried to only add the /dev/sr0 device in docker compose, and then mount that from within the container (docker exec) to /mnt/cdrom, but I only get mount: permission denied (are you root?) errors so far (and yes, I am root AFAICT).

+1

Just wanted to say, that totally agree to @dpprdan observations.
The latest version and nightly-latest do not show the sr0 device.
But v2023.11.2 works as expected.

Interestingly in the "Open Dir" dialog it is schown in the latest version:

[jlesage]

This issue is now fixed with the latest image.

[dpprdan]

🤔 I still don't see sr0 in the "Open Source" dialog

vs the "Open Directory" dialog

But I cannot select it in the latter of course.

[jlesage]

Ah I forgot to commit a change... I will publish another version.

[dpprdan]

It's working now with 2024.01.2! 🎉
Thanks a lot @jlesage!

[extrafein]

Perfect! Thx.
