Hello,

we want to stream a live-event with Wowza (3.x) over HLS or HDS, but not RTMP.

The streaming-format is h264/mp4.

Now we need to know the delay/latency between Wowza and the player (JWPlayer, Flowplayer, Strobe Media Player, or what ever).

Or the other way:

We want Wowza to “inject any signal” in the stream and when this signal arrive the player, the player should do something.

We try to inject cue-points, this did not work I thought (not possible in \*.mp4 over HLS/HDS, only in \*.flv)

We try to use closed caption, this works like a charm with JWPlayer but only with RTMP, not in HLS/HDS…(HLS not supported yet)

How we can solve this problem?

-\>send “signal” over stream OR

-\>find out delay/latency of stream between Wowza and player (our first choice)

About any help I am very grateful.

Best regards

Alex

Alex,

I think you can do cuepoints in Flash HTTP (OSMF):

And take a look at these guides that discuss key frame frequency and chunkDurationTarget, which can be used together to reduce latency
