Raw Normal View History

this is a combo patch that: 1) adds an experimental TS demuxer to mplayer 2) adds an input (streaming) interface from DVB cards. It compiles and runs with the following versions of the drivers: dvb-kernel (HEAD) (with stock kernel 2.4.20) and 0.9.4 (with kernel 2.4.18) patch by Nico <nsabbi@libero.it> some cleanups, ts demuxer fixes by me git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@9611 b3059339-0415-0410-9bf9-f77b7e298cf2
