There is another open source driver implementing the audio and video decoder API: http://cvs.tuxbox.org/cgi-bin/viewcvs.cgi/tuxbox/driver/dvb/drivers/media/dvb/dbox2/Attic/dbox2_avia_av_napi.c?rev=1.1.2.1&only_with_tag=driver_2_6_branch&view=auto The decoder APIs haven't changed much over the last years, so the old PDF document should still be accurate enough to give a brief overview: http://www.linuxtv.org/downloads/linux-dvb-api-1.0.0.pdf > And last question, will a software like mplayer be able to play dvb > streams just with the dvb drivers or does it need the /dev/video and the > v4l drivers ? /dev/video isn't needed. Mplayer for example has the switch -vo mpegpes, which uses the DVB API for playback. For the "full featured" cards this means that the TV-output is used. However, in case you've been looking for it, there is no standard API for using a digital video encoder or an A/V switch, to configure PAL vs. NTSC, RGB vs. CVBS or SCART outputs etc. The CVS tree mentioned above uses a custom interface for it (in driver/avs and driver/saa7126).
