The change essentially removes the delay introduces by lookahead buffer.
The valid audio data in the internal buffer is also flushed to ensure
the integrity of output.

The change in the commit will add some samples to the end of the audio
stream. The intention is to add a "zero_delay" option eventually to not
have the delay in the begining the output from alimiter due to
lookahead.

Hi,
I am wondering if this is a change that would make unpredictable impact on
the stats report for ffmpeg. If this is the case, can you take a look at my
next patch in the series? It adds an option to print stats for each output
file when enabled. Thank you!
Best,
Wang

* "multiple_output_final_stats" is used to display stats for each output when
ffmpeg completes processing.
* Also refactor to add a new function to print verbose stats for input/output
so that the behavior is same as before by default.
Signed-off-by: Wang Cao
From: Wang Cao
It appears the initial intention was to print stats for the first
output. Currently all output streams are aggregated for the final stats
which is inconsistent with the "size" reported in print_report.
For example, when two outputs are specified, output 0 has size
This patch adds the control for enabling rectangular partitions, 1:4/4:1
partitions and AB shape partitions.

For bitrate, I use the stream size to calculate it and I think it's more

we should be able to use X tag to support color range.
Color range would be good to have to give Y4M more capability to

full range).
