[linux-dvb] dec2000-t playback

[alve <ulfonk_mennhar@gmx.de>]

hi,

I'm still looking for a way to playback video from my harddisk through 
the dec2000-t to my tv. So I studied the dvb-api, your driver's source 
and some mpeg documentation and now i think i basically know what has to 
be done. But this is the first time I'm working on a kernel module and 
still I'm not really sure and need some more hints to really start with 
it. so...
- the most important thing is to implement the demux write() function of 
the api for the dec box, correct?
- as we get pes streams from the box when recording, i guess the mpeg 
decoder can only handle pes and we have to transform the transport 
stream that is given to write() so that it can process it.
- we need to know the way the pes packets are transmitted to the dec, so 
I used usbsnoop with the windows app. Seems like i have to read some 
documentation about usb and after that find out how pes pacckets are 
transmitted via usb. Or can you give me some advice?
- most likely we have to tell the box that it has to receive data from 
the usb-bus instead of the antenna/frontend before starting the playback 
- perhaps i can find out how when i understand the usbsnoop log.
- I'm sure there are various things to update in ttusb_dec.c afterwards 
but the only obvious thing i found is registering a pointer to the new 
write-function in ttusb_dec_init_dvb(...) as dec->demux.write_to_decoder.

Am I right that far?

cheers
Ulf
