<div dir="ltr"><div>Hi! </div>Thanks for pointing me to splitmuxsink and splitmuxsrc. That would spare me a good chunk of code.=) The only thing I don't understand about splitmuxsrc is how to specify a specific file list or to modify it in playing state. By default I have a separate directory for each hour of recording. I can stream files from one hour with location=/archive/video/cam/day/hour/*.mp4, but what happens when I finish this hour? The awkward hack is to make a temp directory and add simlinks to videofiles from main archive to it in advance... </div><div class="gmail_extra"> <div class="gmail_quote">2016-03-30 23:53 GMT+03:00 Tim Müller <<a href="mailto:tim@centricular.com" target="_blank">tim@centricular.com</a>>: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Sun, 2016-03-27 at 22:28 +0300, Krutskikh Ivan wrote: Hi, Your subject line mentions 'playbin2' - are you using the outdated and unmaintained GStreamer 0.10 ?

You can also make (uri)decodebin stop autoplugging decoders early so you can transmux without re-encoding, for example (auto* signals). <div><div class="h5"> > The second task is more ambitious.

You probably want something lower-level than playbin. In recent GStreamer versions we have splitmuxsink and splitmuxsrc which you might find helpful in this context. What protocols do you want to stream as? The easiest would be to just use gst-rtsp-server (see gst-rtsp-server/examples for some simple examples).
