The trick here is to find a way of serving the preroll without everyone hearing it. I guess you could use some on connect logic to determine if it should be played, fire up a command line streamer which would stream it to its own mount point which is set to fall back to the main stream, then move the listener to that mount. They would hear the pr...

I was trying to see if there's a way to configure it so that someone with a weak network connection doesn't have to hear our pre-roll over and over again.

We use Icecast version 2.4.4 and recently added an intro (preroll) to one of our channels. Although we haven't had any direct complaints, there has been a discussion thread with some of our public radio colleagues getting complaints about users receiving a repeat of the intro many times when their device switches from WiFi to LTE or unstable Internet con...

Hmmm... i was unaware of this... so how many frames/packets of preroll are required to ensure "perfect" (where perfect = as it would have been reproduced at this point had the file played from the beginning) output ? ie basically what i'm asking is what impact does this have on seeking or editing/cutting/recombining ? Because when you just seek to s...

Hello, icecast provides something like a plugin for vast ads system? Or we have to custom parse the xml and create some playlist to add a preroll mp3 to another stream live? Thanks. BR

...sn't perform as poorly as you might expect. On the other hand, it's not trivial to implemen. Many applications actually seek by byte offset instead, which is an acceptable user experience is some designs. If you're going to write this yourself, keep in mind the complications of decoder preroll (seek to 80 ms before the desired target and decode from there, discarding the extra output, to give the decoder a chance to settle) and chain boundaries (if you see an unrecognized Ogg stream serial number, you'll need to bisect again to find a boundary where the timestamp origin changes). Go...

...point was not that there should be a shared font codec or similar, but that it might be useful to consider a way to supply arbitrary data to multiplexed streams, each codec then interpreting this data as it sees fit (possibly ignoring it).

Hi there, in fact, my purpose is to write tool which will allow one to split ogg file with vorbis audio *and* theora video codecs, but at first I'd like to understand how the splitting of Ogg Vorbis stream works. So I looked at existing tools that split Ogg Vorbis audio files, i.e. `vcut' utility in vorbis-tools package, and Ogg plugin from `libmp3splt', but I found that engine code

...lap consecutive frames, and the timing was constructed so that the 'timestamp' of a vorbis frame actually points to the middle of the frame data. When you combine a starting frame with the subsequent frame, the data you get back is from the starting timestamp forward. Because Opus needs to preroll a larger amount, that trick wouldn't work with Opus.

..., I have no idea). > > Why do you ask?********************************** I'm investigating the possibility of adding Opus to ASF. I will probably use WAVE_FORMAT_EXTENSIBLE instead: "WAVEFORMATEXTENSIBLE allows you to avoid having to register a new format tag with Microsoft." Preroll is supported by ASF. But I'm unsure if pre-skip and end trimming can be supported. I guess one could live without it.
