Media Player says it won't play MP4. But MP4 are on the list of accepted file types?

First: Sorry if I’m in the wrong forum.

My Player is a WDBAAP0000NBK-AESN

Box says: WD TV Live Network Media Player.

My player tells me it can’t handle MP4 (movie) files but the MP4 file type is on its approved list.

Anyone know what’s happening here?

MP4 is a file type, and yes, it is supported.   But the CONTENTS of the file also must be supported.

As the manaul and specifications indicate, the contents of the file must be:

Video:  AVC or MPEG4 

Audio: AAC, AC3, or MPEG Audio.

Other combinations will work, but aren’t officially supported.

If there are any questions about what’s in your file, Please post the full TEXT output of MEDIAINFO for such a file.

TonyPh12345 - thanks. I’ve downloaded Media Info and I’ll check out the offending files shortly and come back.

I remember now that some of these movie files are ‘containers’ for other files. But I thought that only applied to MKV’s.

Being used to simple single-file types, I have trouble getting my head around the concept that one file could be made up of several other types. Like a doc being a blend of txt and pdf files, for example.

Do you know of any websites where these structures are explained in bog-simple terms?

Cheers :slight_smile:

The User Manual has a simple table of supported File Extensions / Containers / Codecs

Page 207 and onwards.

Pretty much all are: mp4, avi, mkv, m2ts…

Hi guys. Thanks for the contributions, most informative.

I’ve installed Media Info and can now right click a movie file and summarize its contents.

Should I post a particular format of the Media Info format? Like - Basic, Sheet, Tree, Html?

Sorry, I see I’ve already been told to post a text output.

Guys, the MEDIA INFO analysis of the offending file (in the previous post) seems to indicate that the MP4 subsidiary files meet the WD Media Player’s requirements.

Is that the case? If so, can anyone suggest a fix for the problem?

You could split a sample with MP4BoxGUI or YAMB and upload it to so we can give it a try. You are correct that from the file specs it looks like it should be working.

Quickest way to fix it … Re-Encode it (eg. Handbrake) 

Re-Encoding a 311MB file would probably take 5-10 Minutes (if that)

Personal example: i got a 3 hour movie a few days ago … played fine for the 1st hour then it started to get really choppy. (like it was dropping frames)

File plays fine on PC (of course :wink:)  but has problems playing on my WDTV Live Hubs internal HDD

Mediainfo:     Result = nothing wrong, winthin spec

MKVToolNix:  Result = Remuxed the file, Time taken: 4 Mins  (did’nt fix it)

Handbrake: Re-encoded the entire 3Gig file, Time taken: 50mins

Result: plays perfectly now
