[FFmpeg-user] bitmap-subtitle in stream

I use ffmpeg on a router to restream a DASH-stream 
(https://live.idnes.cz/slow/slowtv7_720p/manifest.mpd) to a local 
htdocs-folder as HLS on the router. The media-server xupnpd2 reads the 
HLS and transfers it to the TV.

On the DASH-stream website 
is a map with the actual position of the tram. The router is to slow for 
re-encoding using the video-filter "overlay".

Is it possible to integrate a bitmap-based subtitle in the generated 
HLS-stream containing an actual map-image (e.g. 
without re-encoding?

Thanks and best regards,
