mp4

[DVDHelpPlease]

What media plays mp4 files? Or what codec do I need?

[celtic_druid]

To playback mp4 you need:
1) an mp4 parser
2) decoders for contained streams (ASP MPEG-4, AVC, aac, ttext, privates streams)

mplayer, VLC, osmo4, etc. can play mp4. Nero also supports mp4 or you can use say haali's splitter and ffdshow for playback.

[zentaochi]

you can also install the xvid codecs. they support mp4 playback and also ac3 audio

[celtic_druid]

XviD supports decoding of ASP MPEG-4 Video from mp4. That is it. It doesn't support AVC, ttext, aac, etc. or AC3 which has nothing to do with mp4 anyway.

Download Quicktime player or Nero Showtime.

[celtic_druid]

Quicktime's mp4 support sucks. Doesn't support ASP MPEG-4, doesn't support HP AVC, doesn't support he-aac, doesn't support mp3 in mp4, doesn't support ttext in mp4 (does in 3gp), etc.

I tend to use DivX, myself.

I love my Archos when it comes to air travel...

[DVDHelpPlease]

I tried installing the various codecs, ffdshow, Xvid, haali's splitter but none of them worked.

Running it through Gspot everything is N/A except it says it's a NONAVI file type unknown.

I don't understand. I have Divx and Xvid Codecs installed. What others can I try?

Do I have to have haali's splitter and ffdshow installed at the same time?

[zoobie]

again...try vlc player

[DVDHelpPlease]

Thank you that VLC player worked, however one more question, is there a way i could just have it play with Windows media Player? What codec could make the mp4 play like all the other mpegs?

[zoobie]

here's a list of what you can play or convert to play in media player...it also says you can play files with .mp4 file name extensions in the Player if you install a DirectShow-compatible MPEG-4 decoder pack

[celtic_druid]

I already explained what you need.
and yes you need ffdshow (or other compatbile decoders) and haali's splitter installed at the same time. Otherwise you don't fulfil requirements 1 & 2 as outlined above.

The good thing about ffdshow is that it supports ASP, AVC, aac and mp3 decoding. Its subtitle render may also support ttext and Nero VOB subs. Other issue though is that you can store whatever you want in mp4 as private streams, the only examples that I have really seen so far though are apple lossless audio, nero subs, theora and vorbis.

One last thing. ffdshow needs to be enabled to decode whatever streams and for MPEG-4 oddly enough you need to enable DivX 4 since that is the option that handles mp4v.

I did install ffdshow and Haali's splitter and all it did was play the video in Windows Media Player, it had trouble downloading the audio codec to play audio. Any suggestions there?

[celtic_druid]

Was ffdshow enabled to handle aac audio? Should be set to faad2 or realaac.

[DVDHelpPlease]

I looked in the audio configuration and all I saw was ac3, is there another place where I can find the faad2 or realaac?

[celtic_druid]

[DVDHelpPlease]

It was already set on the ACC Realaac. But the video still played without audio. Windows Media Player said it had an error downloading a codec. Not sure which?
