Hi, as there seems to be some interest in this topic, I'm opening a separate thread. Also please use proper in line comments and do NOT top post, as top posting breaks readability and discussion flow. Let's get some things out of the way: I'm going to acknowledge that HLS and DASH are things that are out there. Especially HLS is being pushed by the likes of Apple, in parts quite aggressively. Icecast is a open source multi media streaming server that emphasizes open codecs and formats. I've been repeatedly thinking if Icecast should add support for one of the...

Hi Dear R-users: I am building a R package and would like to create a generic variance function. Here is how I did var=function(x,...) { UseMethod("var") } I wrote a Rd file, put the R code in the right directory, and named var, var.default in the namespace. However, once I typed rcmd check , it gave me an error in S3-generic step. However, that error would not occur for mean and

...ssion 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 connections. One of our colleagues received a response from Triton Digital about "utilizing your HLS enabled mounts for streaming". I am not familiar with this technology, could someone here provide more information about how this could be used with Icecast and how it would help in the case of unstable Internet connections and/or intros? Thanks! -- Robert

...in a codec-agnostic way. Stitching together compressed media streams for gapless playback isn't trivial, and in particular while .ogg and .opus support sample-accurate cuts and cross-lapping for gapless transitions between arbitrary segments, mp3 and aac do not. Moreover, part of the point of HLS was to support bitrate switching for video, so there's an additional synchronization constraint. As I understand it, the mpeg2-ts and related restrictions on audio segmentation come from these constraints this. Unlike mp4, and like ogg, mpeg2-ts doesn't have a seek table, so it's a bet...

Hi Wayne Yep, HLS is something we would like to use with Icecast. As you mentioned, Liquidsoap made a great step in the right direction if it comes to HLS. It seem that icecast might not get this support soon, as you might read in the discussion list. I don?t share these arguments, because we have real world use cas...

...preciate your response. Maybe in my explanation I have some red and green apples, but I can agree that my understanding is as you explained it. 😊 The point is that if I can successfully stream mp4 with H.264 and AAC encoding without any issues to icecast, I can then use ffmpeg to turn it into HLS which then solves my iOS support issue. The CPU cost of repackaging MP4 into HLS architecture should be minimal because at the core it’s all H.264. No transcoding! Low CPU objective achieved! Additional bonus is that I already use Apach2 with icecast and integrating the whole lot into my existin...

...havior as you are severing the connection and re-connecting. It sounds like the same type of case with users with "unstable Internet connections" as they may well be disconnected from the Icecast server and reconnect when network is available again. Icecast, AFAIK, doesn't support HLS ( https://en.wikipedia.org/wiki/HTTP_Live_Streaming ) so I can't comment on that.

.....</dump-file> ? Is it supported? Have been on Linux for less than a year so not sure if at all possible? I have no idea yet what a 1000 fifo's will do. *On another note:* The other BIG issue is to support apple users. iOS/Safari seems to be 11% of the market (https://caniuse.com/#search=HLS) and I cant ignore them. Will have to use HLS to keep them happy but again the CPU overhead is imminent as vorbis/VP8 is miles away from AAC/H.264. Icecast is very CPU efficient ingesting, streaming and writing out a webm file, CPU 1-2%. Same efficiency situation with nginx and RTMP streaming in an...

...en use ffmpeg to Hi, just a quick thing to clarify before you waste too much time on this: MP4 is not streamable due to the way the format works. The header/trailer that a valid mp4 files needs to have, requires "knowledge" of the whole file which makes it impossible to stream it. What HLS or DASH does is not "streaming" in the "traditional" sense of streaming but rather it is downloading small complete file chunks that nowadays mostly use fragmented MP4. You can't stream MP4 with Icecast. If you for some reason have to stream H.264 you could use MPEG TS. Not...

Tom and Frederick. Thank you both for your input. It is greatly appreciated, not only by me, but I am sure for many others who find this thread. Tom - using Linux server for icecast. HLS was brought to my attention a while back on the liquidsoap forum. I have not had a chance to completely look in on it, but do plan on checking it out. Tom. You have your icecast servers in a round robin configuration. Are you using NGINX for that? I have watched several YouTube videos on using it...
