Some words about Siemens-DVB card support. by A'rpi
|
||||
==========================================
|
||||
|
||||
Requirements:
|
||||
~~~~~~~~~~~~~
|
||||
- Siemens DVB-S card or compatible (Technotrend, Galaxis, Hauppauge, etc)
|
||||
See www.linuxtv.org for details and download latest driver there.
|
||||
- MPlayer-CVS, FFmpeg libavcodec CVS are recommended for speed & postprocessing.
|
||||
- Fast CPU - at least 1GHz recommended for software transcoding (DivX -> MPEG).
|
||||
|
||||
|
||||
How to enable?
|
||||
~~~~~~~~~~~~~~
|
||||
|
||||
'./configure' should detect it. If it did not, force detection with
|
||||
|
||||
./configure --enable-dvb
|
||||
|
||||
If you have ost headers at a non-standard path, set the path with
|
||||
|
||||
./configure --with-extraincdir=<your DVB source dir>/ost/include
|
||||
|
||||
Then compile and install as usual:
|
||||
|
||||
make
|
||||
make install
|
||||
|
||||
|
||||
How to use?
|
||||
~~~~~~~~~~~
|
||||
|
||||
Hardware decoding: (play standard MPEG1/2 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. You MUST rescale for other heights by adding 'scale=w:h' to the '-vop'
|
||||
option, where 'w:h' are the width and height you want. Note that DVB cards accept
|
||||
various widths, like 720, 704, 640, 512, 480, 352 etc and do hardware scaling in
|
||||
horizontal direction, so you do not need to scale horizontally in most cases.
|
||||
For example, for a 512x384 (aspect 4:3) DivX try:
|
||||
|
||||
mplayer -ao mpegpes -vo mpegpes -vop lavc,scale=512:576
|
||||
|
||||
If you have a widescreen movie and you do not 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 your CPU is too slow to view a 720x576 DivX in full size, try to downscale:
|
||||
|
||||
mplayer -ao mpegpes -vo mpegpes -vop lavc,scale=352:576 file.avi
|
||||
|
||||
If it is 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 feature of the OSD plugin!
|
||||
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 the
|
||||
image up a bit to get bigger black zone for subtitles. And you may want to move
|
||||
subtitles up, if they are out of your TV screen, use the '-subpos <0-100>' switch
|
||||
('-subpos 80' is perfect for me).
|
||||
|
||||
In order to play non-25fps movies on a PAL TV or with a slow CPU, add the
|
||||
'-framedrop' option.
|
||||
|
||||
|
||||
How to keep the aspect ratio for DivX files?
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To get the optimal scaling parameters (hardware X scaling, software Y scaling,
|
||||
while 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 the OSD feature of DVB cards
|
||||
- better (more fluent) playback of non-25fps movies
|
||||
- realtime transcoding between mpeg2 <-> mpeg4 (partial decompression)
