When I am trying to convert a mpeg video to flash video, but audio seems not be converted into the flv file. What did I do wrong? Many thanks.

By default flv selects mp3 audio but that is not configured in your ffmpeg. Install lame, make distclean, add --enable-mp3lame to configure command, make, retry. This is becoming a FAQ but is not in the FAQ. Besides, this is a general problem: some containers select default codecs that may not be installed, and do so silently! -- Michel Bardiaux R&D Director T +32 [0] 2 790 29 41 F +32 [0] 2 790 29 02 E mailto:mbardiaux at mediaxim.be Mediaxim NV/SA Vorstlaan 191 Boulevard du Souverain Brussel 1160 Bruxelles http://www.mediaxim.com/
