The purpose of this patch is to preserve timestamps when using ffmpeg for
publishing RTMP streams, e.g. ffmpeg -i rtmp://source/stream -f flv
rtmp://target/stream.
There is a setting "copyts" for that purpose. Unfortunately it doesn't work
with FLV muxer because it has its own timestamp correction which makes global
setting "copyts" ineffective.
This patch removes timestamp correction in FLV muxer. This means FLV will rely
on ffmpeg timestamp correction which makes it possible to use copyts.
