Let the client determine if it should cache or not unless we are publishing a live stream.
Fixing typos in a parsing commands (patch by jamie-stackhouse).
Fix EXT-X-PLAYLIST-TYPE parsing
Doc update. No code changes.
Fixes #10 request.
Both parsing and generation added. With these tags library fully supports M3U8 of ver. 4 of the HLS protocol. Version bumped up to 0.3-dev.
Minor change. As described in https://golang.org/pkg/testing/
Year updated to current. Added missed copyleft headers.
It feature completes support for version 5 of the protocol.
Function declared as DuratiofAsInt(yes bool) so seems like set arg to true will set segments durations to integer values, but it has reverse logic. It was fixed and function now works as expected. It changes public API!
It also apply to EXT-X-PROGRAM-DATE-TIME parsing. Unit tests updated.
Docs synchronized with README information.
Export count of mediaplaylist segments
Removed link to streamsurfer as the project unfinished and stopped.
I really don't remember when it was broken or it feature just made unfinished :\ Anyway it passed tests now and seems worked ok.
p.Decode expects a Bytes object, p.DecodeFrom accepts the reader
decodeLineOfMediaPlaylist currently expects a playlist to have
*either* a EXTINF or a EXT-X-BYTERANGE because it's using an
if EXTINF {} else if EXT-X-BYTERANGE {}, this is incorrect as
EXTINF is required and therefore a playlist must always have
an EXTINF, the EXT-X-BYTERANGE is optional.
This change also fixes a bug when an offset given in EXT-X-BYTERANGE
is not reset in its state, so segments without an offset would
incorrect be given the last offset set.
Also includes unit tests to reproduce the issue.
decodeLineOfMasterPlaylist is process a I-Frame line expecting the URI to be located on the next line, however, the EXT-X-I-FRAME-STREAM-INF attribute contains the URI as a tag (unlike EXT-X-STREAM-INF. This changes produces a test which reproduces the issue and also removes the state tracking for this attribute as it's not required.
Currently version is controlled via private version functions and set via the Set* methods when required. This is the ideal method for most applications, as the version is managed by the library This change provides the user the ability to check the version as well as overwrite it, as during some live streams the version number may have been incremented via the Set methods, but once those segments have been removed the version number will change during playback. This isn't ideal as the player may encounter version changes during playback to versions it doesn't support. This provides implementors the ability to announce up front what the version number will be.

Note, this uses a map as a cache, and does not limit its size and therefore could become very large. If this occurs, there's another option which only caches the last result, but assumes all durations are identical, which isn't always true. But does provide equivalent speed improvements when the durations are identical and doesn't involve a map (just two local variables).

Hori improvements - Alternative approach
It is not reflects real development status and not maintained a long time.
* *Breaking Change*: SCTE struct was renamed to SCTE35 * *Breaking Change*: MediaSegment.SCTE was renamed to MediaSegment.SCTE35 * Deprecation: MediaPlaylist.SetSCTE() has been deprecated, use MediaPlaylist.SetSCTE35() instead * SCTE35 (was SCTE) has 3 new fields, `SCTE35.Syntax` defines the format of the SCTE data, `SCTE35.CueType` defines whether the cue point was start/mind/end, `SCTE35.Elapsed` can be used for formats that track the elapsed time. * SCTE35 now supports a another SCTE-35 syntax we've nicknamed OATCLS (due to the presence of this string in the tag), see `sample-playlists/media-playlist-with-oatcls-scte35.m3u8` for an example. Both reads and writes are supported. * decodeParamsLine should support attributes with numbers.
