Usage of overlay filter with "dvb_subtitle" stream causes "Buffer queue overflow, dropping." message

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:

[ffmpeg]# ./ffmpeg -loglevel info  -i "udp://@239.204.5.20:7000?localaddr=10.0.8.36&fifo_size=100000&timeout=10&overrun_nonfatal=1"  -filter_complex [0:v][0:s]overlay=eof_action=pass[v],[v]split=1[out1] -map [out1]  -vcodec libx264 -profile:v  main -preset veryfast -s 1920x1080 -b:v 10000k -minrate 2000k -maxrate 12000k  -bufsize:v 2.8M -pix_fmt yuv420p -g 24 -map 0:s? -c:s copy  -map 0:a:0 -c:a:0 mp2    -map 0:a:0 -c:a:1 libfdk_aac   -flush_packets 0 -f mpegts -mpegts_flags pat_pmt_at_frames -mpegts_flags resend_headers "udp://239.204.5.21:7000?localaddr=10.0.8.36&pkt_size=1316&buffer_size=65536"

Replying to pth7712:

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.

How are we supposed to reproduce the issue?

comment:2 Changed 3 years ago by pth7712

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.

Does this still happens with latest master?
