Thing is: audio packets in this file contain more than one audio frame.

So i wonder if qcelp, and maybe evrc should have CODEC_CAP_SUBFRAMES
added or this kind of muxing is done when no variable rate frames are present.

So your patch may just fix one case, and leave others still broken.

I'm not against this patch to be applied, but its clearly not optimal solution.
