Crash in af_init(), bytes per sample issues

[mplayer-bts@…]

I was trying to persuade mplayer to convert audio to 16 bit before feeding it
to ALSA (or OSS). Earlier versions (eg. pre3) allowed me to do '-af format=2'
but this does not work in -pre7 ("The number of bytes per sample must be 1, 2,
3 or 4. Current value is 8").

So I tried '-af format=u8' randomly:

The crash was reproducable with any AVI generated by my digital camera (Canon
A60) and any file I tested with 8 bit audio
(eg. /usr/share/sounds/KDE_Beep_RimShot.wav).

My sound card's a CM8738, BTW.

Please retry with latest CVS.

[mplayer-bts@…]

(Okay, so perhaps it wasn't clear that only bugs in the CVS version should be
reported).

But as it turns out, the bug is identically reproducable in 20050501 CVS (I
hope that is recent enough for you :P). I hope you don't mind that I reopened
the bug.

Let's start anew.

Hope this helps!

(In reply to comment #2)

But as it turns out, the bug is identically reproducable in 20050501 CVS (I
hope that is recent enough for you :P). I hope you don't mind that I reopened
the bug.

I said that because I applied the fix just minutes ago before I posted my reply,
so if that is recent enough depends on when you did the update on that day (so I
actually think your version is too old)

[reimar]

Anyone tried this recently?
