In http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#dvb it says:
USAGE. Hardware decoding (playing standard MPEG-1/2 files) can be done with this command:
mplayer -ao mpegpes -vo mpegpes file.mpg|vob
Software decoding or transcoding different formats to MPEG-1 can be achieved using a command like this:
mplayer -ao mpegpes -vo mpegpes yourfile.ext
How is that ment?
now the description in video.xml is crystal-clear
4) In connection with mpegpes there is also mpeg-4 mentioned. Is that for chips which can do mpeg-4 hardware decoding?
none of them is supported; maybe there's an example to transcode from dvb input to mpeg4
I don't think the examples show a way of transcoding to mpeg4 for they just have a video filter addition. Have a look for yourself.
excerpt from video.xml_ <para> If you want to record it in a different format (re-encoding it) instead you can run a command such as <screen> mencoder -o <replaceable>r1.avi</replaceable> -ovc xvid -xvidencopts bitrate=800 \ -oac mp3lame -lameopts cbr:br=128 -pp=ci dvb://<replaceable>R1</replaceable> </screen> </para> change xvid with lavc and adjust the encoding options as you prefer to obtain mpeg4
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 It seems this is outdated.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?
it's been possible since dvb:// and demux_ts were added to mplayer
Doing some research with your hint to demux_ts I wasn't able to find any examples or hints how to transcode my dvb input to a mpeg4 output-file. Could You please provide some?What programme is in charge for transcoding mplayer or mencoder? (I know there is the programme transcode as well;))
mencoder
What uses demux_ts: -demuxer lavf or -demuxer mpegts?
isn't the filename clear enough? demux_ts; anyway -demuxer lavf can be used to demux dvb streams, too
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.
??
Doing some tests I found out that only -vo xv,svga,aa,fbdev allow me to use 'h' or 'k' to change the channel without dropping input reads. I am very fond of the vidix driver. Is it a bug that it doesn't work with cvidix nor xvidix?
What original file should I use for creating a patch to the DVB-docs?
Regards, Lynx
xvidix does accept 'h', 'k' and shows the osd menu. I use it every day -- "Without a frontend, mplayer is useless" - someone in mplayer-users
