Playlist is a formalized list of video and audio files that can be played back on media player. MAG STBs support the M3U playlist format.
A playlist is a text file with the extension m3u - playlist example.

Playlist channels are added to the STB in IPTV channels section and displayed as IPTV channels list. Usually playlist files are added (imported) to the STB: 1) from external network, by URL; 2) from local network or USB drive, from specific folder. Also, users are able to manually add and edit the IPTV channels list .

Playing media content

Opening channel means starting media content playback with STB player. Each channel specifies playback options that determine:

  • format of Audio / Video stream
  • and decoders required for playback
  • network or local address of media content.

Player is controlled via API. For more details see JS API MAG200 (Rev 1.20) (pdf).

Media content playback options

Channel playback options are set and edited in URL option of Edit window.

Format of URL option is as follows:

Solution + Stream address
where:

  • Solution - provides player with required format and proper decoders for audio and video stream playback. List of values for Solution is shown in the table below.
  • Stream address - network or local address of media content. It can contains IP address, port number, path to file on server.
Type of “Solution” Description
auto Automatic detection of content type, container, codec by givern URL, if the URL begins from rtp:, udp:, rtsp:.
rtp

Play string in format MPEG2TS. If URL begins with rtp: then RTP stream will be played. if URL begins with udp: then UDP stream will be played.

rtsp Sets required codecs if additional information on the stream is present, for example, H.264, AC-3 ,etc.
ifm Play an audio stream Internet radio
fm Play audio from MPEG-TS stream (udp:, rtp:)
ffmpeg Play files in various formats: avi, mkv,mpg, mp4, mov, wmv, AC-3,
ffrt Play MPEG-TS stream from the http server.
ffrt2 Play streams with http, rtmp, … container but there may be no MPEG-TS. Looping content is always on (SetLoop(true)).
ffrt3 Similarly ffrt2, but assumes no realtime stream. That is, with the ability to position itself on the content. Suitable for playing back videos from YouTube.
ffrt4 Similarly ffrt2, but is used to quickly launch streaming using rtmp (rtmp:// ...).

Detailed information can be found in document: JS API MAG200 (Rev 1.20) (pdf) (Section stb.PlaySolution. page 19.) (Appendix 2. Video content formats and examples of use. page 89)

To play streaming

Streaming specification should be as follows:

rtp space URL

for example:

rtp udp://10.20.30.40:1234
rtp rtp://10.20.30.40:1234 

For access to stream with RTSP-server specification should be as follows:

rtsp space URL

More information can be found in document:JS API MAG200 (Rev 1.20) (pdf) (Section stb.SetupRTSP page 35)


For broadcasting http

for example:

ffmpeg http://10.10.30.40:12434

It is also possible to use the following Solution - fm, ffrt, ffrt2, ffrt3. Depending on type of streaming.

HLS-stream

HLS (HTTP Live Streaming) supports live stream and video on demand (VoD) modes. To transfer audio and video data by HLS protocol, the MPEG2-TS transport stream is used. HLS protocol splits transport stream into fragments (files) that are stored on web server along with index-file that contains information about the order in which series files must be played. The index file extension is m3u8. In below example of playlist channel in HLS format is the last entry.
