LLHLS Dump for VoD Service

Set <Application><Publishers><LLHLS> as follows.

<LLHLS>
	<Dumps>
		<Dump>
			<Enable>true</Enable>
			<TargetStreamName>stream*</TargetStreamName>
			
			<Playlists>
				<Playlist>llhls.m3u8</Playlist>
				<Playlist>abr.m3u8</Playlist>
			</Playlists>

			<OutputPath>/service/www/ome-dev.airensoft.com/html/${VHostName}_${AppName}_${StreamName}/</OutputPath>
		</Dump>
	</Dumps>
        ...
</LLHLS>

LLHLS Live will be dumped for VoD to the directory you configured. This allows you to provide VoD streaming with Apache or Nginx.

You can test it with the master branch, it will be released from 0.14.11.

wow a great feature. Thank team AirenSoft!

@getroot Can this feature combine multiple VODs of a stream key multiple times. Currently using only the most recent VOD live stream

[getroot]

@NkInKaIgIe Do you mean merging videos? Or do you mean separating directories?
Combining videos is difficult. Re-transcoding may be required. Separating directories can be solved by "time macro {time:ddhhss}" or creating a new folder when there are duplicate folders. (Or let me know if you have any good ideas.)

Hello, this feature is incredibly useful for us too!

Working great at a technical level, but we cannot use it because re-streaming to the same endpoint keeps recreating the llhls.m3u8 as @NkInKaIgIe said. I tried the time macro from the FILE publisher but it didn't work.

[getroot]

@p4block I haven't implemented the time macro in LLHLS dump yet. I'll add it soon.

I found a strange quirk, it's only recording the first 24ish seconds of our test streams. Files sizes on disk match this and ovenplayer just stops. Happened with sample videos and an ffmpeg testsrc. Are we doing something wrong on our end?

[getroot]

@p4block
I don't know what the sample videos and ffmpeg testsrs are.

Did you try to play VoD after the live stream completely ended? Or did you try to play VoD while the live stream was in progress? Have you tried refreshing the page that is playing VoD? The chunklist is constantly being updated. Of course, that can happen if you try to play in the middle of a live stream. Players load the chunklist once when playing VoD and do not automatically update it again. Because it is VoD.
If there is no problem, try uploading your dumped m3u8 files for me to see. Uploading the ovenmediaenigne.log file also helps.

@getroot I'm tring to play after the streaming ends, and it's not about the player itself, as the files on disk are actually that small. I tested with video files dumped from IP cameras and with this ffmpeg testsrc command.

ffmpeg -re -f lavfi -i testsrc2=d=3600:s=1280x720:r=24,format=yuv420p -f lavfi -i sine=f=440:b=4 -shortest -c:v libx264 -vf format=yuv420p -preset ultrafast -crf 24 -bf 0 -an -f flv "rtmp://ourtestserver:1935/app/stream-desktop"

cat default_app_stream-desktop/llhls.m3u8 
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-INDEPENDENT-SEGMENTS

#EXT-X-STREAM-INF:BANDWIDTH=2000000,RESOLUTION=1280x720,FRAME-RATE=24.0,CODECS="avc1.42c01f"
chunklist_0_video_llhls.m3u8

These videos have quirky timestamps, but that wasn't an issue before with streaming or file output. Can test tomorrow with the Big Bunny movie or something. Logs in OME show nothing relevant, although I did not enable any kind of debug mode.

[getroot]

@p4block I need the chunklist_0_video_llhls.m3u8 file. Please upload that and does your llhls live play normal?
and please check if there are any problems when using OBS and let me know.

What is the advantage of this method for VODs vs recordings
