Hello,
I've tried parsing my file

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:1582061
#EXTINF:10, no desc
#EXT-X-PROGRAM-DATE-TIME:2016-01-01T18:22:09Z
20160321T150304_2_5560256_1582061.ts
#EXTINF:10, no desc
#EXT-X-PROGRAM-DATE-TIME:2016-01-01T18:22:19Z
20160321T150304_2_5560256_1582062.ts

I get a list of TimeItem which makes sens, but how can I get the filename (.ts) ? Does this lib support this format?
thanks

Such as the files that iTunes outputs when exporting playlists.

It's understandable (and clearly necessary) to have a library that handles HLS m3u8 files, it would just also be nice to import these other standard files.

Had a few minutes of head scratching when I tried calling M3u8::Playlist.read with a path before I realized I needed an IO object. Calling read with a path doesn't throw an error and returns a playlist regardless

irb(main):002:0> M3u8::Playlist.read("~/Desktop/long_hls")
=> #<M3u8::Playlist:0x007fb77388de20 @version=nil, @sequence=0, @cache=nil, @target=10, @type=nil, @iframes_only=false, @independent_segments=false, @items=[]>

It looks like when this gets rendered it's missing the #EXT-X-PROGRAM-DATE-TIME, only rendering the time. I'm not sure if this was an intentional design decision or a bug? It looks like it's been in there for 5 years if it is a bug, so wanted to make sure before working on a PR.

Details:

...
playlist.items << M3u8::SegmentItem.new(program_date_time: Time.now, duration: 10, segment: 'http://example.com/segment-1.aac')
....

Expected:

#EXTINF:9.770667,
#EXT-X-PROGRAM-DATE-TIME: 2020-11-25 14:27:00 -0600
http://example.com/segment-1.aac

Actual:

#EXTINF:9.770667,
2020-11-25 14:27:00 -0600
http://example.com/segment-1.aac

the latter seems to cause players to try and request "2020-11-25 14:27:00 -0600" as a fragment url.

I worked around the issue for the timebeing by passing the "#EXT-X-PROGRAM-DATE-TIME: #{Time.now}", as the program_date_time attribute, which feels a little clunky unless I'm missing the reasoning for it being this way. Thoughts?

Hi,

would you consider a PR that would add the non-standard Name attribute to #EXT-X-STREAM-INF?

This is used by Wowza and JWPlayer to show a quality selector option in the player (see https://support.jwplayer.com/customer/portal/articles/1430240-hls-adaptive-streaming )

Thanks

If a live stream finishes, the #EXT-X-ENDLIST tag must be included in the end

See 6.2.1. General Server Responsibilities

If the Media Playlist contains the final Media Segment of the
presentation then the Playlist file MUST contain the EXT-X-ENDLIST
tag; this allows clients to minimize unproductive Playlist reloads.

Is it possible to create an mp4 file from a given playlist url?

Thanks for making this library!

Is there a built-in search feature, ie. find the item with the best video resolution? Or at least a less clunky way than:

item = m3u8.items.max_by { |e| (e.respond_to?(:height) && e.height) || 0 }

Wouldn't it be simpler and better if the object returned was a symbol hash rather than an object with methods?

Recently I had a use case where I was looking to convert a M3u8::Playlist to M3u8::PlaylistItem. I was a bit surprised it's not supported by this gem, and that PlaylistItem instances need to be built from an options hash. This doesn't seem like a rare use case, especially when working with a master playlists, parsing media playlists they contain, working with them, and building a new master playlist as a result.

Here's a short example use case I'm imagining:

my_file = File.open('spec/fixtures/media_playlist-664.m3u8')
media_playlist = M3u8::Playlist.read(my_file)
playlist_item = M3u8::PlaylistItem.new(media_playlist)

My temporary workaround for this is to dump all of a Playlist's instance variables into a hash (excluding items, etc.) and building a new PlaylistItem from that. If there's a more intuitive way to do this that I'm missing, please let me know.

A secondary solution could be to implement a Playlist#to_options method that returns an options hash that allows for easy creation of a PlaylistItem:

my_file = File.open('spec/fixtures/media_playlist-664.m3u8')
media_playlist = M3u8::Playlist.read(my_file)
playlist_item = M3u8::PlaylistItem.new(media_playlist.to_options)

If you are on board with the feature request, I'll be happy to write the specs and open a PR.

Thanks!
