Subject: wma_afh: Compute the chunk time more accurately.
X-Git-Tag: v0.4.1~19
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=3f24334e12773c5d4c9a602073e5f9a7c4a6d3f4;hp=e5a8a6805e12baade86cdab549b80863c2d1a843

wma_afh: Compute the chunk time more accurately.

We already know the exact chunk time: It's a multiple of frames_per_chunk.
