Description
Summary of the bug:
Usage of overlay filter with "dvb_subtitle" stream causes "Buffer queue overflow, dropping." message. I can
reproduce it only when the input is "live" MPEG-TS.
Overlay filter is used with 0:v as primary and 0:s as secondary stream. The subtitle stream is with DVB bitmap subtitles inside.
Seems like overlay filter doesn't process main input while the secondary is starving.
How to reproduce:

Hi,
you need a live mpeg-ts stream with dvb subtitles stream. I cannot send multicast over the Internet.
BTW,
maybe related effect occurs when the input is from MPEG-TS file (not a multicast stream). Then the overlying is very slow, but "Buffer queue overflow" doesn't appears. Seems like (but only seems) the overlay waits for subtitle PTS before do something.

Hello,
removing:
-map 0:s? -c:s copy
from the arguments list, fixes the issue.
Maybe this can help.
