Description kevin van (reporter) 2009-10-30 23:08:56 UTC
SOFTWARE VERSION:  2.2009.42-9

If video playback fails, the N900 needs to be rebooted to restore maemo media
player video playback functionality.


1. Take an iphone spec sized video file and copy the video to the N900 video
folder (480 x 270 H264 video file).  [I would attach such a video file here but
you have no attachments for your bug database - please contact:
kevin@elgato.com for such a video - or you can easily create one by using
QuickTime export to iPhone format)

2. On the N900, go to Media player -> Video.  Locate video file and try to

3. Playback fails... you get the message "Unsupported file format". Cancel
error message.

4. Go back to the video file list and attempt to playback a file that you know
works, say the video that is pre-installed on the N900, the video called "Nokia
N900" or the "9" video.


Plays back video.  The maemo player should gracefully handle video file it can
not playback.  It should give a warning, and then you should be able to
playback a video that is know to work.  You should not have to reboot the Nokia
N900 to restore maemo video playback functionality.


Player comes up, but all you see is a black screen with the video controls.  If
you try to press the "Play" button, nothing happens.  If you try to hit the
arrow keys or seek in the video, nothing happens.  The workaround is to reboot
the N900 phone.  Then upon reboot, go to Videos section and playback the video
that you know works on the phone, namely the "9" or ""Nokia N900" video.

You can create attachments here (see "Create a New Attachment" link), but only

having the same problem here. can't play the videos taken from the N900 camera.

get the following error (screenshot attached):
Unable to play media. 
Media format not supported.

I am attaching the 10sec video that I took with the N900 just before writing
this. the media player gives the same error when trying to play the video.
thumbnail is not displayed either.

rebooting fixed the problem. thumbnails are displayed in the media-player too.

Confirming. This is an issue with h264dec encoded videos.

The problem reported here should be fixed in the update released today for
public: The Maemo5 update version 2.2009.51-1 (also called "PR1.1" sometimes).
Please leave a comment if the problem is not fixed for you in this update
Comment 8 lucasara 2010-01-14 14:39:10 UTC
I still get this in 2.2009.51-1.

I have a mp4 file that won't play (avc + aac), if I try to play it I get "media
format not supported".

If I try to open any other compatible video file after that one, the controls
open but nothing is played and play button is unresponsive. If I try to play an
internet radio station or any mp3, a message saying "media format not
supported" appears.

Reboot fixes it until I try to open the unsupported video...
Comment 9 Taomyn 2010-01-15 12:47:03 UTC
I'm also experiencing this with the latest update - I had some video clips from
my old Samsung i8190 many of which would not play, although one of them would
strangely. Attempting to playing them would cause any other video to either
fail with "Unknown format" (even video recorded on the phone) or sit in a blank
screen loop. Reboot required to fix.

I've run into this on PR1.1 in trying to do some troubleshooting for this TMO

Possibly related/bigger issue?

I think that's bug 6823 which is still valid in 2.2009.51-1.

Hm.  Maybe this bug should depend from that?
Comment 14 Nils Faerber 2010-03-15 00:18:06 UTC
I can confirm this bug, still valid in 2.2009.51-1 and also happens sometimes
when playing DivX or XVID in formats that the N900 does not 100% support.
Sometimes stopping playback soon enough helps to keep the subsystem playing,
sometimes a reboot is necessary.
