This time hls ran very quickly! For my hls tests I've been using a command line in a terminal so I can ensure that I repeat the same command. On the previous occasions hlsbest was only running at around 8 fps. This morning it was running at over 400 fps. Big increase! :-) Once that was happening I modified my own simply ROX app for fetching lists of items, and it duly rattled though half a dozen at over 400 fps. Really pleased and relived. I have no idea why it was so slow before, but may have simply been down to bad luck and I did it when something was getting in the way, or whatever. The hls fetches seem to throw up a complaint about packet timing which I associate with the lip sinch being affected. However I tried a few of the resulting files and they seem fine. The Bach Cello Sonatas were a good test of that, but meant I then got hooked... 8-] Is it the norm for hls fetches to start with a warning about the timings? Its similar to the messages I can get when using ffmpeg to clean up DVB-T2 stream grabs. > In the not too distant future, HLS will become the only option for us to > use.

Yes, I've been well aware of that for some time! You may have missed when I did a webpage on 'Audio Factory' that deals with the overall developments. I was told then that RTMP would probably stay though the Proms. But beyond that it may well go soon. The changes this week are a step along the way towards the eventual demise of RTMP I think. Now relieved and pleased that hls works here OK! :-) Jim -- Electronics http://www.st-and.ac.uk/~www_pa/Scots_Guide/intro/electron.htm Armstrong Audio http://www.audiomisc.co.uk/Armstrong/armstrong.html Audio Misc http://www.audiomisc.co.uk/index.html _______________________________________________ get_iplayer mailing list [email protected] http://lists.infradead.org/mailman/listinfo/get_iplayer
