8ecbb1f9af fftools/ffmpeg_mux: stop rescaling timestamps in of_streamcopy() 
This function converts packet timestamps from the input stream timebase
to OutputStream.mux_timebase, which may or may not be equal to the
actual output AVStream timebase (and even when it is, this may not
always be the optimal choice due to bitstream filtering).

Just keep the timestamps in input stream timebase, they will be rescaled
as needed before bitstream filtering and/or sending the packet to the
muxer.

Move the av_rescale_delta() call for audio (needed to preserve accuracy
with coarse demuxer timebases) to write_packet.

Drop now-unused OutputStream.mux_timebase.

26e1e80152 fftools/ffmpeg_opt: reimplement -streamid using a dictionary 
This does not require an arbitrary limit on the number of streams.

Also, return error codes from opt_streamid() instead of aborting.

3a89e6d352 fftools/ffmpeg_filter: restrict reap_filters() to a single filtergraph 
This is more natural, as all except one of its callers require
processing only one filtergraph.

dff3a283cd fftools/ffmpeg: rework -enc_time_base handling 
Read the timebase from FrameData rather than the input stream. This
should fix #10393 and generally be more reliable.

Replace the use of '-1' to indicate demuxing timebase with the string
'demux'. Also allow to request filter timebase with
'-enc_time_base filter'.

4d06742b93 fftools/ffmpeg: add more structure to FrameData 
It now contains data from multiple sources, so group those items that
always come from the decoder. Also, initialize them to invalid values,
so that frames that did not originate from a decoder can be
distinguished.

01897c1788 fftools/ffmpeg_dec: move decoding to a separate thread 
This is only a preparatory step to a fully threaded architecture and
does not yet make decoding truly parallel - the main thread will
currently submit a packet and wait until it has been fully processed by
the decoding thread before moving on. Decoder behavior as observed by
the rest of the program should remain unchanged. That will change in
future commits after encoders and filters are moved to threads and a
thread-aware scheduler is added.

f8abab673c fftools/ffmpeg: move sub2video handling to ffmpeg_filter 
Make all relevant state per-filtergraph input, rather than per-input
stream. Refactor the code to make it work and avoid leaking memory when
a single subtitle stream is sent to multiple filters.

a6d67b11f5 fftools/ffmpeg_filter: move sub2video subtitle queue to InputFilterPriv

a subtitle stream is sent to multiple filters then each should have its
own queue.

5d530e3a72 fftools/ffmpeg_dec: move sub2video submission to ffmpeg_filter 
This code is a sub2video analogue of ifilter_send_frame(), so it
properly belongs to the filtering code.

Note that using sub2video with more than one target for a given input
subtitle stream is currently broken and this commit does not change
that. It will be addressed in following commits.
