For WMP to be able to read a media file, it needs that various DirectShow filter to be present on PC : - a source filter to parse the MP4 file format : - read the format - identifiy the used codecs - demux payload and timestamp - appropriate filter for the elementary stream decoder Unfortunately, Windows comes pre-installed mostly only with support for Windows Media files and codecs (plus a little of MPEG-2 and MP3). So you need to install a package for this. I suggest using ffdshow. ffdshow is an open source package that provide DirectShow filters around ffmpeg project. This will include both MP4 file format and MPEG-4/H.264 decoders plus a lot of other stuff. Other solution is to install a player that natively support those formats. This is the case of VLC, MPlayer or QuickTime for example (may have restrictions on the supported profiles) Beware also that the demo on the board DO NOT generate MP4 format. They generate elementary stream that should be stored with a .M4V (resp. .264) extension. Some recent versions of VLC and MPlayer can read those files directly. MP4 is, as you pointed, a multiplexed container. Mis-naming an elementary stream as a MP4 may prevent it to be read correctly by some players. => M4V files cannt be played in WMP using ffdshow but can be played on VLC for example. If you want to generate a proper MP4 file from the M4V elementary stream, you can use the mp4box or mp4ui tools.

Normally , an mp4 file should contain both video and audio but video and audio seperate in Encode demo ? That's why WMP cannot detect that file though it was saved on mp4 format. Have you got any documents talking about video/audio formats used in DaVinci ? Regards, Quan __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
