I've been testing out playing videos in 14.2 stable, 32-bit, and for some reason they play fine in VLC, Xine, and Kplayer but not in Mplayer or Dragonplayer.

In Mplayer, the sound works, but the video screen doesn't appear. I installed SMplayer through sbopkg and that worked.

In dragonplayer, the program opens, but when I select a video to view it does nothing.

Here is my terminal output for dragonplayer: Again selecting a video does not work.

bash-4.3$ dragon

dragonplayer(31137) KSambaSharePrivate::getNetUserShareInfo: "Can't load /etc/samba/smb.conf - run testparm to debug it
"

I have libdvdcss, and mplayer-codecs installed and was wondering why the other 3 players work no problems and these two are not.

Any ideas?

What are the video and audio encoded as?

Dragon may require a different backend. Check System Settings > Multimedia and check to see what engine you're using for Phonon.

MPlayer "should" work, although it really just depends on the codec that the video is using.

Lists Gstreamer Phonon as the backend notKlaatu.

Try VLC or Xine as backend.

How do I go about editing that? I can't add/change it from the settings manager.

Hmmmm............I can open and play a movie file using mplayer in the terminal. So I know it works.

Still can't get dragon player to play video though. :-(

what is this unknown video?
a store bought dvd?
a wmv?
a avi?
a mp4 ?
what
i have a few microsoft only wmv's that will ONLY play on windowsmedia player
but after trans coding to mp4 they do
these had sound but no image

I've tried .avi, dvd, .mp4, .mkv, .flv........no luck! Dragon Player opens but plays nothing!

Let me guess - you haven't installed samba?

Samba is installed. Patched to newest version from the security advisory.

Sorry - I have the same smb error in my terminal output when running dragon. Didn't spot it first time around. dragon does play videos here, however. 14.2 64-bit.

Sorry for the delayed reply... I was out of town and am trying to get caught up on the forum.

Have you installed the various gstreamer libraries? dragonplayer doesn't use mplayer as a backend, so just because something plays properly in there, doesn't mean it will play elsewhere. It's very likely the dragonplayer uses gstreamer as the backend like the rest of KDE, and if so, Slackware can't ship with many plugins that provide proper playback support due to license/patent restrictions. Try installing gst-plugins-ugly, gst-plugins-bad, and gst-libav from SBo (taking note to install any optional/required dependencies for those that you might need).

Hey bassmadrigal, I had gst-plugins-ugly, gst-plugins-bad previously installed. The missing culprit it seems was gst-libav.

I installed gst-libav from SBo and dragon player works fine.

Thanks for the help!

Had the same.. My status was:

- All gst-things including good/bad/ugly/libav installed.
- when playing video files: for all that I tried: sound yes, picture: no...
- gmplayer's GUI control window opens, the video window does not open.

From command-line, I tried gmplayer <video-file-name> and found message:

Failed to open VDPAU backend libvdpau_va_gl.so: cannot open shared object file: No such file or directory
[vdpau] Error when calling vdp_device_create_x11: 1
Error opening/initializing the selected video_out (-vo) device.
==========================================================================

Seems like: gmplayer is using a -vo 'device' (vdpau..) that is not installed

Funny thing: when starting mplayer <video-file-name> I got both sound and picture... No control GUI,
but: the video window opens and plays, sound and all..

From that, I got the idea to 'play' with the settings of gmplayer... I re-started the
gmplayer, opened the 'wrench' settings screen, and selected -in my case/ near-random- the
gl / opengl video device. gmplayer informs that it needs a program-restart to activate this.

After that, gmplayer 'just works'.. Also, from command-line, the status line now reads..

[gl] using extended formats. Use -vo gl:nomanyfmts if playback fails.
==========================================================================

As far as I understand: it's 'just' that gmplayer's default video output 'device' is configured
to a non-functional one... The rest of gmplayer is just feeling fine...

Just so you know, gmplayer is not really developed anymore. There are much better frontends for mplayer, my personal favorite being smplayer. It provides a ton more options and makes plenty of filters easily accessible.
