Subject: ffmpeg_filter: initialize sub2video.end_pts together with last_pts
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=8cf757ee8d806c581ce453546c4e98cf746a442e;p=ffmpeg

ffmpeg_filter: initialize sub2video.end_pts together with last_pts

This way re-initializations properly update end_pts, enabling
sub2video_heartbeat to call sub2video_update as expected to re-init
the sub2video AVFrame's contents and to feed a frame into the filter
chain.

This then fixes memory usage ballooning due to framesync waiting
for secondary input in case of no actual subtitle samples being present
for a while in source after a re-init occurs.
