Some words about Siemens-DVB card support. by A'rpi
|
|
==========================================
|
|
|
|
Requirements:
|
|
~~~~~~~~~~~~~
|
|
- Siemens DVB-S card or compatible (technotrend,galaxis,hauppage etc)
|
|
see www.linuxtv.org for details and download latest driver there.
|
|
- MPlayer-CVS, ffmpeg-libavcodec CVS are recommended for speed & pp.
|
|
- Fast CPU - 1GHz+ recommended at least for software transcoding (divx->mpeg)
|
|
|
|
|
|
How to enable?
|
|
~~~~~~~~~~~~~~
|
|
|
|
./configure should detect it. If didn't, force with ./configure --enable-dvb
|
|
If you have ost headers at non-standard path, set it with:
|
|
--with-extraincdir=<your DVB source dir>/ost/include
|
|
make
|
|
make install
|
|
|
|
|
|
How to use?
|
|
~~~~~~~~~~~
|
|
Hardware decoding: (play standard mpeg 1/2 files)
|
|
|
|
mplayer -ao mpegpes -vo mpegpes file.mpg|vob
|
|
|
|
Software decoding/transcoding anything to mpeg1:
|
|
|
|
mplayer -ao mpegpes -vo mpegpes -vop lavc yourfile.ext
|
|
mplayer -ao mpegpes -vo mpegpes -vop fame,expand yourfile.ext
|
|
|
|
Note: the DVB card only supports height 288 and 576 for PAL,
|
|
240 and 480 for NTSC. For other heights, you MUST rescale it,
|
|
by adding 'scale=w:h' to the -vop option, where w:h are width:height
|
|
you want. Note, that DVB card accepts various widths, like 720, 704, 640,
|
|
512, 480, 352 etc, so you don't need to scale horizontally in most cases!
|
|
(the card will do hardware scaling in horizontal direction!)
|
|
For example, for a 512x384 (aspect 4:3) divx try:
|
|
mplayer -ao mpegpes -vo mpegpes -vop lavc,scale=512:576
|
|
|
|
If you have widescreen movie, and you don't want to scale it to full
|
|
height, you can use the 'expand=w:h' plugin to add black bands.
|
|
For example, to view a 640x384 divx, try:
|
|
mplayer -ao mpegpes -vo mpegpes -vop lavc,expand=640:576 file.avi
|
|
|
|
If you have slow cpu to view 720x576 divx in full size, try to downscale:
|
|
mplayer -ao mpegpes -vo mpegpes -vop lavc,scale=352:576 file.avi
|
|
Or if still slow, try to downscale vertically too:
|
|
mplayer -ao mpegpes -vo mpegpes -vop lavc,scale=352:288 file.avi
|
|
|
|
Do you want osd, and subtitles? Use the expand plugin's osd feature!
|
|
So, instead of expand=w:h or expand=w:h:x:y, use expand=w:h:x:y:1
|
|
(the 5th parameter :1 at the end will enable osd rendering)
|
|
You may want to move image up a bit to get bigger black zone for subtitles.
|
|
And you may want to move subtitles up, if they're out of your TV screen,
|
|
use the -subpos <0-100> switch (-subpos 80 is perfect for me).
|
|
|
|
To play non-25fps movies on PAL TV, or with slow CPU, add option: -framedrop
|
|
|
|
How to keep aspect ratio for DivX files?
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To get the optimal scaling parameters (use hardware for X scaling, and
|
|
scale Y by software, keeping the right aspect ratio), use the new 'dvbscale'
|
|
plugin:
|
|
|
|
for 3:4 TV: -vop lavc,expand=-1:576:-1:-1:1,scale=-1:0,dvbscale
|
|
for 16:9 TV: -vop lavc,expand=-1:576:-1:-1:1,scale=-1:0,dvbscale=1024

Future plans/TODO:
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
- display OSD and subtitles using DVB card's OSD feature
|
|
- better (more fluent) playback of non-25fps movies
|
|
- realtime transcoding between mpeg2 <-> mpeg4 (partial decompression)
|
