I was having problems using vlc, but I found out that the version of chromium included in 7.4.0 plays videos without problems "about chromium": Version 37.0.2062.120 Built on Debian jessie/sid, running on Debian 7.6 (281580) I would like to find out internally what player it is using and with which parameters ... How is it you run an application in debugging mode so that all functions calls are dumped on standard error or output? Thanks, lbrtchx
