[HLS] manifest with chapters - playback problem

[mtr81]

I get from server HLS manifests:
manifest_1.txt
manifest_2.txt
It's live streaming, but if I use ISA the playback starts from first TS file (not current time). This problem doesn't exist during playback via inputstream.ffmpegdirect.
After adding properties:

play_item.setProperty('ResumeTime', '43200')
play_item.setProperty('TotalTime', '1')

playback started from correct point, but after 10 minutes player back to first segment.

Not exactly. In this case problem is incorrect #EXT-X-DISCONTINUITY support.

it's still the same issue regardless of stream. Kodi doesn't keep track of the chapters on manifest updates.
Solution is also the same: use proxy to remove the chapters.

more info also on this issue: #584

I haven't tested but i'm pretty sure it's the same problem i solved long time ago on DASH

inputstream.adaptive/src/parser/DASHTree.cpp

Lines 138 to 157 in 6b8cb37

	//! @todo: can have sense to move period selection on PostInit or another place
	//! just before the session initialize period, that will be a common code for all manifest types,
	//! also because the code related to live delay calculation on AdaptiveStream::start_stream
	//! can potentially fall on the previous period and so its needed to set in advance the right period
	//! so live delay and period selection could be merged
	//! to do this its needed to test also the behaviour of HLS streams with discontinuities
	uint64_t now = stream_start_ - available_time_;
	if (m_isLive && !kodiProps.IsPlayTimeshift())
	{
	for (auto& period : m_periods)
	{
	if (period->GetStart() != NO_VALUE && now >= period->GetStart())
	m_currentPeriod = period.get();
	}
	if (!m_currentPeriod)
	m_currentPeriod = m_periods.back().get();
	}
	else
	m_currentPeriod = m_periods.front().get();

I think it's never been fixed on HLS because a decent solution is not so simple to do like on dash,
in order to fix this other things would have to be revised and changed in some way as well
