[Mplayer-dvb] Audio resampling 44.1 -> 48 Khz with DVB-s

[Achim Lange]

Hello Arpi,

I just read on the mplayer homepage that 0.60 was released. Congratulations!

I hope, my question is not answered somewhere in the docs, I looked but did
not find it. My last "knowledge" was, that the resampling only worked in a
CVS version for the Hollywood-card.

Now I read, that the resampling is a generic feature for the released 0.60.

I tried several divx-files (44.1 kHz-audio with -aop
list=resample:fout=48000 or 49152 (which would be more suitable for the
DVB-card?)), but sometimes Mplayer stops replay after 1-2 secs (there is a
start-picture of the film on screen), consuming 99% CPU-time, but does
nothing you would see or hear. (with -vc ffdivx, regardless of -framedrop or
not)

With -vc odivx it dies after around 1 sec with "interrupted by signal 8 in
modules: flip_page"

Without the -aop option and -vc ffdivx the movie plays, but with unusable
sound (the alien problem).

Is this expected behaviour with 0.60 and DVB, does it make sense to try a
CVS-version or do I just have to be a little more patient? :)

Thanks for your great work,

    Achim


P.S. here is a complete "log", in case it is not expected behaviour:
