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
https://slowtv.playtvak.cz/prave-ted-mazaci-tramvaj-jede-prahou-d73-/mazaci-tramvaj.aspx?c=A150908_111659_mazaci-tramvaj_plap
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.
http://staticmap.openstreetmap.de/staticmap.php?center=50.05619,14.43873&zoom=15&size=800x300&maptype=mapnik&markers=50.05619,14.43873,ol-marker)
without re-encoding?
In theory, you could provide subtitles but all formats are palettized
and creating a palettized image also takes time. In any case, you
would have to implement this programmatically.
Carl Eugen
Could someone provide a workflow how to do that programmatically. Until
now I have only worked with the ffmpeg-application in combination with
xupnpd2 mediaserver.
Thanks, Thomas
