Dotaz: Debian vlc a transcode

[Jiri]

Zdravim, mam problem pri jednoduchem pokusu transkodovat video [1.]. Dostany debug hlasku [2.]. Predpokladam, ze problem je v konstalaci ffmpeg a libavcodec nicmene oboji mam nainstalovano [3.]. Zkousel jsem na debian unstable i stable oboji stejne. Nemate podobnou zkusenost ci radu. Dekuju. Jirka

No mozna ten enkoder nemas v distribuci. Na mpeg2 drzi asi nekdo nejake patenty. Gstreamer napriklad encoder v Debianu asi nema viz.
