[vlc-devel] [PATCH] avcodec: Set time_base for audio encoders, too

[Martin Storsjö]

This is required when encoding audio in libav 0.8, otherwise
it will crash due to a division by zero.
---
A patch for fixing it in libav has been sent, but it might be
a good idea nevertheless to set time_base, to fix usage with
the 0.8 release.
