Thanks for the advice , but no joy.
Does anyone know any other repositories where ffmpeg with swf / flash are enabled?
ffmpeg - multimedia player, server and encoder - Medibuntu package
This package contains the ffplay multimedia player, the ffserver streaming server and the ffmpeg audio and video encoder. They support most existing file
formats (AVI, MPEG, OGG, Matroska, ASF...) and encoding formats (MPEG, DivX, MPEG4, AC3, DV...).
This package is built with the "risky" option, to enable mp3/mp4/h264/amr support. Therefore, it is in Medibuntu as it might violate patents.
This package isn't supported by Ubuntu: DON'T REPORT BUGS TO UBUNTU!
