3e47bbad56 ffmpeg: don't delay printing initial stats 
The first stats is printed after the initial stats_period has elapsed. With a large period,
it may appear that ffmpeg has frozen at startup.

The initial stats is now printed after the first transcode_step.

842714b5cb ffmpeg: add option stats_period 
At present, progress stats are updated at a hardcoded interval of
half a second. For long processes, this can lead to bloated
logs and progress reports.

Users can now set a custom period using option -stats_period
Default is kept at 0.5 seconds.

Derive input parameters from correct inlink when using ppsrc.
