Extend IPTV recorder to support TS streams over HTTP 0.27

[lincoln@…]

Hi

I have made a feature patch against fixes/0.27 that adds IPTV support to http transport streams. This enables direct support with a DM500 Dreambox (Enigma 1) but should work with many stb's.

The patch changes the following:

1. New HTTPTSStreamHandler class (subclass of IPTVStreamHandler) to enable stream support for Http TS streams.

2. Extend iptvtuningdata to include a protocol type for udp, rtp, rtsp, http_hls, http_ts. This is used to determine the type of stream handler to use and differentiates between http-hls and http-ts.

3. Extend ChannelUtil::GetIPTVTuningData to include setting the protocol type (above) in iptvtuningdata. UDP, RTP, RTSP and HTTP are determined by the URL name, and HLS and TS are differentiated by downloading a limited sample of the URL to check if it is an HLS playlist or a HTTP_TS video stream.

4. Extend MythSingleDownload? to support a maximum file size limit. Without this, if the URL from (3) is a video stream and not a playlist then the download would not terminate until the 30 second timeout. Limiting file size solves this problem and still allows accurate testing for a playlist.

5. Extend tv_rec to include a new system event for Tuning Timeout. This allows user to run a script to reboot the STB in the event that the channel lock fails due to the stb freezing.

This patch is succeeds #11487.

With more MPEG-2 TS via HTTP streams on the Internet some appear to be unrestricted (no GEOIP, so good for testing) e.g. ​http://x4012c4000.edge.core-cdn.net/40000mb/live/4672family/familytv.ts

Extend IPTV recorder to support TS streams over HTTP

1. Subclass IPTVStreamHandler to HTTPStreamHandler to add IPTV stream support for Http TS streams.
2. Extend iptvtuningdata to include a protocol type for udp, rtp, rtsp, http_hls, http_ts.
3. Add to ChannelUtil::GetIPTVTuningData to set the type based on URL and by testing if the URL is a HLS playlist
4. Extend MythSingleDownload? to support a maximum file size limit. Without this, if the URL from (3) is actually a video stream then the download would not terminate until the 30 second timeout.
5. Extend tv_rec to include a new system event for Tuning Timeout. Allows user to run a script to reboot a STB.

Closes #12168

I've been applying the patch against fixes0.27 plus commit e740947. Have been running this for 2 months now and happily recording IPTV using HTTPTS. Can you apply to fixes0.27 as well?
