From: Jan Ekström <jan.ekst...@aminocom.com>
With some streams multiple nullptr AVSubtitles can get pushed
into sub2video_update() in a row.
This causes end_pts, and on the next round pts, to become
INT64_MAX, latter of which signals EOF in framesync, leading to
complete loss of subtitles from that point on.
Thus, utilize the previous sub2video.end_pts as both the pts and
end_pts in case a nullptr AVSubtitle is received. This lets further
incoming subtitle packets be properly processed, as EOF is not hit
in framesync.
