Greetings all,

Code: 
$ mpv dvd://
libdvdnav: Using dvdnav version 6.0.1
libdvdread: Could not open /dev/cd0 with libdvdccs
libdvdread: Can't open /dev/cd0 for reading
libdvdnav: wm: failed to open/read the DVD

Any ideas?

Kindest regards,

Hate to ask but have you tried to see if it plays on Linux? As it is, you haven't given us too much information. Another option is to see if you can make it into an iso and play that. There's various ways, I cover a few on my by now somewhat dated page, http://srobb.net/dvds.html
 
Hi scottro,

thank you for the reply, I do not have a Linux machine, both mine are runnig FreeBSD. I am not sure what more information I could add, so if you can advise me, I can do that.

Hi Alexander 88207,

with all respect due, have you read the code that I posted? See the third line.
Kindest regards,

Just guessing. Have a look on /dev to see how the your driver is called (eventually /dev/sr0) and then configure multimedia/mpv accordly.

I don't have any "disc" driver to have a look and give you a clue.

This plays for me the first chapter but if i remember i had problems (like using the dvd menu) with mpv as well so i switched to totem.
 
Hi rigoletto,

thatnk you for the reply. Can you please amplify your response, I am not quite sure what/how I am supposed to look at in the /dev. The whole issue with DVD is just a consequence of finding that the multimedia/mpv does not play sound on files that I have stored on hard drive, giving me a message "unknown audio track", which is encoded with acc-lc, and very low sound on other clips, even with mixer set at maximum. I confirmed that both my speaker output and headphone output work, so I thought that I will try to play a DVD to ascertain whether it is a problem with a specific codec or "mpv-wide."

Hi Alexander88207,

as much as I appreciate you trying to help, please note that the multimedia topic is unfamiliar for me, so far everything, movies, sound worked using multimedia over Internet, so if you could please be more verbose, I would appreciate it.

Kindest regards,
M

Oh sorry :(

I use normally multimedia/totem to play DVD's.

This how i do it:

sudo totem dvd://
 
Your user must be member of operator group to read /dev/cd* check the permissions with ls -l /dev/cd*

About the files that mpv doesn't play, run file youraudiofile.aac to identify them, you can download and play sample files like these. I just tried and mpv can play all of them (first table)
 
Hi Criosphinx,

thank you for the reply.
Code: 
ls -l /dev/cd*
crw-r----- 1 root operator 0x68 Feb 25 20:02 /dev/cd0

The mpv cannot play any of the files, all are marked "Audio Track: 1/1 [unknown]." However, when I check /usr/local/etc/mpv/encoding-profiles.conf, the section * audio codecs * shows, "AAC", "AC3", "MP3", etc.

Any ideas?

Kindest regards,

M
 
Greetings all,

I do not think that the codecs are not the problem. Trying:
Code: 
$ mpv --ao=oss /path/to/file/ff-16b-2c-44100hz.ac3
  (+) Audio --aid=1 (ac3 2ch 44100Hz)
AO [oss] 44100Hz stereo 2ch s32
A: 00:00:59 /00:03:07 (31%)
However, still no sound over either speakers or headphones. The same result with --ao=sndio.

Kindest regards,

Hi rigoletto,

I do not think this is the culprit:

Code: 
$ mixer
Mixer vol      is currently set to  67:100
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to 100:100
Mixer line     is currently set to   1:1
Mixer mic      is currently set to  67:67
Mixer mix      is currently set to   1:1
Mixer rec      is currently set to   1:1
Mixer ogain    is currently set to 100:100
Recording source: mic

Also both $ cat /dev/random >> /dev/dsp1.0 and $ cat /dev/random >> /dev/dsp4.0 generate noise in headphones and speakers respectively.

Kindest regards,

M
 
Hi rigoletto,

there are way more options listed; the only one I changed is to enable sndio audio support. But, as noted above, both

Kindest regards,

Hi rigoletto,

thank you. I have rebuilt the port with the default options, i.e., with sndio disabled, and when I invoke an audio file, e.g., the ff-16b-2c-44100hz.ac3 by double clicking it, the mpv (1) player window appears on a monitor and a faint sound is heard. Similarly, when I invoke the audio file from a command line, e.g., $ mpv --ao=oss /path/to/file/ff-16b-2c-44100hz.ac3 no mpv (1) player window appears on the monitor, but I do have louder sound. The level of the sound is much louder, actually listenable, when the command is run from the root account than when run from the user account.

Hi SirDice,

the output of id:
Code: 
uid=1001(username) gid=1001(username) groups=1001(username),0(wheel),1002(ssh-user)

Thus. although this is step forwrd, still the sound level needs to be addressed. Is there a gain setting apart of the mixer? Is there any reference on sound in FreeBSD for dummies, so that I can at least attempt to understand the issues?

Kindest regards,

M
 
Have you started the sndio service? IIRC there are some reports of issues when running the service (search on forums), and you indeed don't need to start the service.
 
Hi rigoletto,

I have initially compiled the port with the sndio service, but removed it in the current recompile based on your recommendation. What my reply Yesterday at 8:32 PM referred to was all with ao=oss. Thus I am confused by your reply.

Kindest regards,

M
