Can someone check a stream for me as my ffmpeg does not work anymore.

I updated to lasted git and today i tried my hard subs again, but no dvb subtitles at all.

test CLI
./ffmpeg -i ../bbc.ts -b 1000k -ab 96k -scodec dvbsub -f mpegts -y a.ts

Now we see Subtitles are available, but not in the output stream.

Just did a clean git pull and same problem, NO DVBSUBS in the output map, i have tried adding in a "-slang eng" but same outcome

Any ideas
