The VideoLAN Forums

Unfortunately cannot find much reference to this codec but it is used on QNAP NAS storage surveillance solutions. To my frustration those are played fine under Windows Media Player on Windows.

I can provide test .avi's of logfile information if needed.

Thanks!

Did you try VLC 2.1.0 nightly builds?

Thanks, actually I didn't. I tried this evening but seem to have a hard time to get it compiled under OS X 10.8. But also appear to fail with the stable builds, so unless there are general issues known for 10.8 I will need to see whether I can fix this and try then.

just take a prebuilt from Nightly Build of VLC

Fair enough, didn't realize that those were there as well. Thanks for pointing out.

Using 2.1.0 from 30. July (nothing later there) and indeed - video is working. Unfortunately no sound for those QMP4 avi's though. Tested other types and they seem to be good with audio.

So getting closer, should adjust the request to QMP4 avi audio support..

Please share a file then.

Sorry, missed the response. Will try to create a file after testing the latest build again and send it across if the problem still exists.

Thanks!

Qnap Nas (new 2014) stores surveilance videos in an .avi format as mentioned above, Qmp4 format. Only once you try to play the .avi does it reveal its a Qmp4 format

and it cant play it

VLC now says

"Codec not supported "VLC could not detect the format "qMp4" (No description for this codec) ... on my PC

mmmmmmmmmmm

Just downloaded the Beta

Version 2.2.1 Weatherwax (Intel 64bit) for mac

http://nightlies.videolan.org/

and This problem is fixed --

My video Now plays from Qnap for 1st time ever in VLC

Happy

UPDATE : ALSO WORKS fine WITH BETA Version 3.0.0-git Vetinari (Intel 64bit)

Yes, I told you I fixed it.

Hi guys,
This topic saved me for the previous QMP4 issue, I installed the latest nightly build, worked perfectly, many thanks!
...until... I Updated QNAP Surveillance Station a few days ago and...

latest VLC (19/04) now tells :
"Codec not supported: VLC could not decode the format "wMP4" (No description for this codec)"
Same with 'wIVG' Motion JPEG

Can someone tell me why the hell qnap are changing their formats all the time? (I got not explanation from their support services)
Sorry if I didn't look first at an eventual 'Codec request - Support for wMP4 (QNAP wMP4)' recent topic --- getting p*ssed off

'w' stands for what? Windows ?

Cheers,
Chris.

Please share those 2 files, with wMP4 and wIVG.

QNAP is changing their format all the time to avoid that you can play it with VLC.

Thanks Jean-Baptiste,

Okay, they hate VLC, but... do they provide or promote a particular player instead ?
If no, I don't see the point in their strategy in that case...

Please share those files. Seriously.

Hi Jean-Baptiste,

Here's a dropbox link to the files, together with MediaInfo & Gspot analysis on both files, just in case it can help :

Thanks for your support, whatever you can fix it or not !

Chris.

up... if I missed something, please, let me know
I sent you an email for the share

Fixed, a long time ago.
