Hi , Does Microsoft has a MPEG-4 simple profile codec (ISO 14496) supported in Directshow or Windows Media format SDK? It seems Microsoft MPEG-4 Video Codec v1,v2 and v3 are not iso compliant. But there is one "ISO MPEG-4 video version 1.0" compression format mentioned. Why so many codecs?? Which codec is going to be hot in the coming years? WMV, MPEG-4? Any inputs would be highly appreciated! regards, Anoop ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
