[FFmpeg-devel] [PATCH] libavformat/mpegtsenc: allow to set service_type in sdt

[dhead 666]

Description:

This adds an option to set the service type in mpegts as define in ETSI 300
468.

I've been using this to pipe internet radio stream (originally as HLS/m3u8)
from ffmpeg to tvheadend, when the service type set right tvheadend
recognize the mpegts stream as a radio channel.

This have been test against master and it closing issue #4118
.
linuxstb from the hts freenode channel originally written the patch and
allowed me to push it upstream.
