Resampling option causes eof problems.

[dev.null@…]

This started as my odyssey to convert a batch of ra files to mp3 (success now,
thank to sipro reordering code by Roberto bug 435). Along the way I tested
various mplayer configurations to create a wav file as a basis for compression
by lame.

I found that adding af options would generate a file padded with a lot of noise
because the encoding would continue at eof with "MPlayer interrupted by signal 1
in module: uninit_getch2 - MPlayer crashed. This shouldn't happen."

See below the results of my testing:

Roberto did some reordering magic and got MPlayer playing old (sipro) ra files
playing in MPlayer -- thanks.

But now I have discovered what I believe to be a bug in the af code (or maybe in
the interaction between Roberto's fix and the af code).

The interesting thing is that this creates a 497M wave file that is listenable
but of which, it appears only the first half contains the whole of the signal.
What follows is silence punctuated by regular ticks.

I wanted MP3 files and so thought to first create wav file at 44.1K. So, I
tried the following command:

$ mplayer -v test.ra -af resample=44100:0:1 -ao pcm:waveheader,file=test.wav -vc
dummy -vo null

It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.

rm audiodump.wav

Works for me with SVN r20347 and the rjltest.ra sample from bug #435.
