[MPlayer-advusers] DVB documentation unclear/outdated

[lynx.abraxas at freenet.de]

Hallo!


I  now  have  an  DVB-T  USB  stick  working  and  went  through  the  mplayer
documentation for DVB. I find this section of the docs very confusing and  out
dated. Here some suggestions:

1)  What is ment by dvb output? Can ff-dvb-card (full  featured  dvb cards) be
use with mpegpes for hardware encoding??? Or does it mean one can use  ff-dvb-
cards  to  decode  any  mpeg-stream  by the hardware even if it is not DVB? If
that's ment the term dvb output is very confusing. I'd suggest something like:
"Use full featured dvb  cards  to  do hardware decoding on mpeg2-streams other
than dvb, eg. dvd vob-files"

2) The hardware decoding example differs from the first software decoding line
only in the file name. Does the file extension make the difference?

3) Is mpegpes only ment for ff-dvb-cards? If so, it should be mentioned as now
a days budget cards get more and more common.

4) In connection with mpegpes there is also  mpeg-4  mentioned.  Is  that  for
chips which can do mpeg-4 hardware decoding?

5)  It  could  be  said  in the dvb input part that an alang-option set in any
configfile can lead to no sound if the language is not in the stream.

6) Last there is "realtime transcoding between MPEG-2  and   MPEG-4   (partial
decompression)" mentioned. It seems this is outdated. In my researches I found
out that in 2002 it had been  dropped  off  the  ToDo-list.  I  couldn't  find
anything newer to that concerning mplayer/mencoder. Is it possible now? If so,
how? As far as I  can  understand  I  found  something  about  it  at  the  TU
Braunschweig.  (mpeg-4  transcoding http://www.ibr.cs.tu-bs.de/users/brandt/ )
Can that be use for mplayer?


Finally: If I use the keys 'h' or 'k' to change the channel when watching dvb-
t  mplayer  changes  it  but  then  does  not  take any further input from the
keyboard. Ctrl-C works though. Same happens when I use the menu with dvbsel to
change the channel. What can I do about it?

MPlayer rules!

Thanks
