[PATCH] libfreemheg: support BBC iPlayer

Reported by: Lawrence Rust <lvr@…> Owned by: stuartm
Priority: major Milestone: 0.27
Component: MythTV - General Version: Master Head
Severity: medium Keywords: MHEG iPlayer
Cc: Ticket locked: no

Description

This series of patches adds support for "Interaction Channel" (ETSI ES 202 184 V2.2.1) which enables BBC iPlayer and other http based interactive content to be accessed from the MHEG 'red button'.

0001: A patch to ringbuffer to support low bandwidth sources. This is optional but if omitted playback of http streams can be very jerky and/or fail
0002..0006 : Various bug fixes to libfreemheg required to use Interaction Channel
0007: Add the ASN1 codes for Interaction Channel
0008: Add a ringbuffer type to support interactive streams
0009: The meat of the Interaction Channel changes

In d848f2d99776da7d51dc64b6eec2f72ba0aecd84/mythtv:

freemheg: Don't return an object not present error until timeout occurs

Remove the error return in GetCarouselData? when GetDSMCCObject returns
'not present' since the object and/or data may arrive later.

This fixes a problem with the BBC interactive logo not being displayed
after switchiong to a BBC channel.

  • Status changed from accepted to assigned

The only patches which have not been applied are those related to improving low bitrate streaming, Daniel is working on a different approach to the same problem

comment:7 Changed 10 months ago by peper03@…

Added a patch to initialise MHIContext::m_notify, which appears to have been the reason for playback of (non-MHEG) videos pausing instead of exiting at the end (see ​http://www.gossamer-threads.com/lists/mythtv/users/543839).

In a2bd7268d63c056df9ff804af4fb438fc5d8f845/mythtv:

Added missing initialisation of MHEG member variable that sometimes caused (non-MHEG) video playback to pause at the end.
