i'm not saying that gmerlin _is_ doing a bad job. afaik, it does the best job _in general_ (supports most formats, allows to access random-access, ...) whether it does a bad job in the specific case i cannot really tell, but it seems so. anyhow, you can select a different backend using yet another parameter to the "open" message: [open foo.mov RGBA quicktime4linux( should open "foo.mov" in the RGBA-space using "quicktime4linux" (rather than gmerlin). afair, the backend is merely a suggestion, and if the desired backend is not able to open the given file, it will fallback to the default behaviour. fgamsdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk/zKDEACgkQkX2Xpv6ydvRkvwCeK7HHFehUnm7C0oU9zc30EQX5 OAYAmwWSnDgoLKGE5j9G7M11WqBZZoOb =SyKW -----END PGP SIGNATURE-----
