[linux-dvb] High system load when replaying a recording with AC3 and help setting up a fifo

[Stefan.Hagendorn@lindy.cc]

Does anyome detect a very high systemload when playing an AC3 recording ???

Is this due to the pipe which wrotes into a programm .. is there a way to
reduce it like pipe into a fifo and let the decoding program read from
there ??

Btw .. can anyone show me how to setup a FIFO .. let VDR pipe the ac3data
into the fifo and read with a decoder programm from this fifo, but only if
it is not NOTHING .. The Problem on my site is: When ac3dec is started it
mutes my digital input because it switchs the soundcard to raw data. I have
connected the dvb-s to the digital input. This way I can hear the tv-sound
an mix other pcm over the soundcard (like playing mp3). VDR now opens the
pipe to ac3dec everytime a recording is replayed, even if it does not
contain ac3 data but the dvb-s is muted for me :-(

Thanks in advance
Stefan
