Custom MPEG-TS Input

Requirement

The TVHeadend 3.9.2100 and up for the pipe:// URL support. Note that TVHeadend expects the input in the raw MPEG-TS format with correct PAT/PMT tables.

IPTV URLs

Note: Always try the command without pipe:// prefix on standard command line, if it works with a stdout redirection to a file!!

Internet Radios

Unfortunately ffmpeg can't set the right header for Radios, so they'll show up as TV Channels :(. So while its not ideal, you can show a static image (the Radio Logo maybe?)

pipe:///usr/bin/ffmpeg -loglevel fatal -nostdin -loop 1 -y -i /path/to/image.png -re -i INPUTLINK -vcodec libx264 -acodec copy -mbd rd -copyinkf -flags +ilme+ildct -fflags +genpts -metadata service_provider=RADIOPROVIDER -metadata service_name=RADIONAME -tune zerolatency -f mpegts pipe:!

Transcoding.

YMMV with different ffmpeg/libav versions. In Red Hat's (Fedora/Centos) build of ffmpeg, aac transcoding is experimental, so you have to enable -strict -2

pipe:///usr/bin/ffmpeg -loglevel fatal -nostdin -i INPUTLINK -vcodec libx264 -acodec aac -strict -2 -copyinkf -flags +ilme+ildct -fflags +genpts -metadata service_provider=STRING -metadata service_name=STRING -f mpegts -tune zerolatency pipe:1

Try to transcode as little as possible, since it will impact your cpu usage. And if you're using tvheadend to re-transcode... well..

So if your channel already has aac audio, maybe you only need to transcode the video stream.

pipe:///usr/bin/ffmpeg -loglevel fatal -nostdin -i INPUTLINK -vcodec libx264 -acodec copy -copyinkf -flags +ilme+ildct -fflags +genpts
  -metadata service_provider=STRING -metadata service_name=STRING -f mpegts -tune zerolatency pipe:1

Direct copy

pipe:///usr/bin/ffmpeg -loglevel fatal -i INPUTLINK -vcodec copy -acodec copy -metadata service_provider=STRING
  -metadata service_name=STRING -f mpegts -tune zerolatency pipe:1
