746d27455b ffmpeg: move decoded frame counter from after post-processing to decode 
This way we can call process_subtitles without causing the decoded
frame counter to get bumped.

Additionally, this now takes into mention all of the decoded
subtitle frames without fix_sub_duration latency/buffering, or filtering
out decoded reset/end subtitles without any rendered rectangles, which
matches the original intent in 4754345027
.

fcc50674de ffmpeg: refactor post-decoding steps for subtitles into a function 
This enables us to later call this when generating additional
subtitles for splitting purposes.

260f391893 fftools/ffmpeg: always generate CFR output when -r is used 
Current code may, depending on the muxer, decide to use VSYNC_VFR tagged
with the specified framerate, without actually performing framerate
conversion. This is clearly wrong and against the documentation, which
states unambiguously that -r should produce CFR output for video
encoding.

FATE test changes:
* nuv-rtjpeg: replace -r with '-enc_time_base -1', which keeps the
  original timebase. Output frames are now produced with proper
  durations.
* filter-mpdecimate: just drop the -r option, it is unnecessary
* filter-fps-r: remove, this test makes no sense and actually
  produces broken VFR output (with incorrect frame durations).

efe4423627 fftools/ffmpeg: store forced keyframe pts in AV_TIME_BASE_Q 
Rather than the encoder timebase. Since the times are parsed as
microseconds, this will not reduce precision, except possibly when
chapter times are used and the chapter timebase happens to be better
aligned with the encoder timebase, which is unlikely.

This will allow parsing the keyframe times earlier (before encoder
timebase is known) in future commits.

95af0bcc34 fftools/ffmpeg_mux_init: postpone matching -disposition to streams 
Do it in set_dispositions() rather than during stream creation.

Since at this point all other stream information is known, this allows
setting disposition based on metadata, which implements #10015. This
also avoids an extra allocated string in OutputStream that was unused
after of_open().
