The format is now:
-bsf:X filter1[=opt1=str1/opt2=str2],filter2
ie the parameters are appended after the filter name using '='. As ','
has been reserved already for the list of filters, '/' is just an
example of token separation for now, but that could become part of the
API to avoid each bsf using its own tokenization.
The proper solution would be using AVOption, but this is overkill for now.

So far ffmpeg used recommended configuration only for codec priv options.
ffmpeg will use now codec defaults and then apply recommended configuration
for all options. Recommended configuration possibly contains minimal
set of options to filful user configuration.

new_output_stream creates a codec context with arbitraty picked codec.
Later data is updated, but priv_data are left alone.
There is a bit chance there is a mismatch between codecs.

Replace "frames to record" with "frames to output". The "to record"
makes it seem like an input option, or that it would capture the frames
instead of outputting them.

This automatically shifts input timestamps to start at 0 instead of the file's
starting timestamp when using -copyts.

This patch is the same as 8a1714ad85 but
applied to encoding. It fixes the current clash of the -password option
between tta decoder and the icecast protocol.
This allows "-codec copy -f framecrc" on files with only unindentifyable streams

Currently the file overwrite check does not work for paths that
contain a colon.
Use avio_find_protocol to always execute the existence check if
the file protocol is going to be used.
Fix remaining part of ticket #3249.

Fixes different behavior to JM and probably several if not all
reference decoders.
We cannot just do this unconditionally as it would ruin AV sync in
some use cases.

previously only codec_ids could be forced, which did not allow
forcing a specific implementation like libopenjpeg vs jpeg2000.
