[FFmpeg-devel] [PATCH v6 2/3] ffmpeg: move decoded frame counter from after post-processing to decode

From: Jan Ekström <jan.ekstrom at 24i.com>

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 4754345027eb85cfa51aeb88beec68d7b036c11e
.
