In particular, it makes it clear the silence_start is not accurate in

Support AV1 encoding using libaom
This contains some extra changes taken from the libvpx encoder
wrapper, most of them contained in the set_pix_fmt() function.

Fixes parsing of expressions like c0=c0+c0 or c0=c0|c0=c1. Previously no
error was thrown and for input channels, only the last gain factor was used,
for output channels the source channel gains were combined.

The generic code should be able to finish the streams just fine initializing
and flushing the filters and codecs properly.
Fixes the following command:

Subtitles which contained styled UTF-8 subtitles (i.e. not just 7 bit
ASCII characters) were not handled correctly. The spec mandates that
styling start/end ranges are in "characters". It's not quite clear what
a "character" is supposed to be, but maybe they mean unicode codepoints.
FFmpeg's decoder treated the style ranges as byte idexes, which could
lead to UTF-8 sequences being broken, and the common code dropping the
whole subtitle line.
Change this and count the codepoint instead. This also means that even
if this is somehow wrong, the decoder won't break UTF-8 sequences
anymore. The sample which led me to investigate this now appears to work
correctly.
This is for applications which want to explicitly check for invalid
UTF-8 manually, and take actions that are better than dropping invalid
subtitles silently. (It's pretty much silent because sporadic avcodec
error messages are so common that you can't reasonably display them in a
prominent and meaningful way in a application GUI.)
