1450,ffmpeg does not terminate after end of input (asyncts used),lvm,,"Hello.

I have an issue when using ""asyncts"" audio filter:

ffmpeg command line
{{{
ffmpeg -i /tmp/flv.flv -vn -af asyncts=compensate=1 -acodec libfaac -f mpegts -y /tmp/xxx.ts
}}}

Everything seems to be OK until source runs out of data (EOF and connnection close are tested) or user decides to abort ffmpeg execution (hits ctrl+c).
In both cases ffmpeg does not terminate and starts to produce huge amount of messages (thousands per second) to stderr:

}}}

until kill or ctrl+c is issued by user.

Problem occurs only when asyncts filter is used:
