Re: [SlimDevices: Plugins] BBC Sounds Dropping out
Thank you all for the suggestions and help, in the last week I have been playing with as many variables as I can think of from individual players to groups to synchronisation and updating software where possible and necessary. In summary I can find no consistent reason for the occurrence it still happens but not at predictable times or frequency. It is at the level of minor irritant not major problem will keep working on it. Anyway thank for your efforts and the work you all do on this project.

That makes perfect sense, and explains what is happening. One of your players is becoming disconnected from LMS (for an unknown reason) and when it is coming back online it is getting all the other synchronised players to restart at the point it was disconnected. *BBC Sounds Plugin Wiki* : https://github.com/expectingtofly/LMS_BBC_Sounds_Plugin/wiki expectingtofly's Profile: http://forums.slimdevices.com/member.php?userid=63263 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] BBC Sounds Dropping out
Had reached the conclusion there was some disparity on the timings between the stream and the players. first thought was to increase Min Synch adjustment to 5/6 seconds but max allowed appears to be 1000 ms Have been thinking about this and looking at previous post, and at screen 32863 and concluded that maybe in my case I do not need synchronisation of a live radio feed because the chances of encountering any 2 systems simultaneously are low and the need to rewind is one I would be unlikely to use therefore I am going to set the Maintain Synchronisation to off and then see what happens. Maybe the options here should be altered to Maintain Synchronisation while playing Maintains Synchronisation while playing except Live Feed Radio No synchronisation +---+ |Filename: Capture.JPG | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=32863| +---+ comeng's Profile: http://forums.slimdevices.com/member.php?userid=63874 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Essentially, 4 times during that log your players are asking the live stream to be rewound by a few seconds by calling a seek to a specific place in the stream. Sometimes this causes a gap, sometimes it doesn't but it would always cause an audible hiccup. I'm guessing that is all part of the synchronisation logic. However, this all part of the problem. The BBC Sounds seeking logic is only accurate within 6.4 seconds (it does it by chunks that the audio is provided in). The live rewind is meant to be a convenient and useful way to rewind live radio, not a facility to jump to a specific point in time accurate within a micro second. It is just not intended for that purpose. I've no idea how the synch logic works and when it uses the seek facility to keep it in synch. I'm guessing that one of your players is running ahead or behind your other players for some reason, but I guess it wouldn't need to do it by much to cause a problem over the hours you are synchronising live radio for. That is probably normal. There may be a setting I should set to prevent the seeking facility being used by the synch logic, I'll ask in the developer forum. But I hope that explains the problem to you. *BBC Sounds Plugin Wiki* : https://github.com/expectingtofly/LMS_BBC_Sounds_Plugin/wiki expectingtofly's Profile: http://forums.slimdevices.com/member.php?userid=63263 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

On the BBC Sounds live streams, although they support seeking, thinking about it, it won't be able to get the data fast enough without causing a drop out for all the players. There is probably something I should set to prevent that happening, (probably not allow seeking when players are synched) I'll have a dig around to find out what should happen. *BBC Sounds Plugin Wiki* : https://github.com/expectingtofly/LMS_BBC_Sounds_Plugin/wiki expectingtofly's Profile: http://forums.slimdevices.com/member.php?userid=63263 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] BBC Sounds Dropping out
I am feeling particularly thick today so I am trying to get a simplistic view on this situation My thinking (which maybe wrong) was the LMS server says to each player here is what you are going to play, then says start now. After which the server steps back and allows the players to do the business just monitoring what is coming down the stream for display on the web interface Now the implication is that there is feedback from the players to the server saying I have just played bit x or bit y or bit z and it maybe for some reason these are not identical and therefore something either the server or the "master" player says resynchronise so the leading player stops playing for a millisecond or two to let the others catch up. Or the slowest one has to jump forward and if the error gets too great then then server says restart. Or alternatively the server streams the feed to each player separately and the server is continuously calling for more data to pump to the players and if one player cannot accept a package from the server for whatever reason the server calls a halt. Whichever scenario is appropriate then variation for synchronisation should be in milliseconds and not seconds running into a minutes. So my thought is to carry out a test of firstly each Pi in turn unsynchronised to see if there is an issue with a particular Pi. Then synchronise 2 Pi's out of 3 using all 3 possible combinations 1-2, 1-3, 2-3 Then go back to all 3 Pi's Does this seem to be a reasonable suggestion on how toidentify the problem area Phil comeng's Profile: http://forums.slimdevices.com/member.php?userid=63874 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

It is the player that is initiating the seek, which is what the logs are showing. The BBC Sounds live streams are a bit unusual, in that they are seekable. Most live streams aren't, so they can rewind, which I believe the synch processing uses to keep players in synch. I haven't don't much testing of synched players on the BBC streams, so there maybe something I can do to prevent that. *BBC Sounds Plugin Wiki* : https://github.com/expectingtofly/LMS_BBC_Sounds_Plugin/wiki expectingtofly's Profile: http://forums.slimdevices.com/member.php?userid=63263 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

It seems to be streaming away quite happly At 14:08 and 15:14 I can see that the stream was paused and woken up again, hence the seek. Essentially you did a rewind on the stream. The player stopped asking for data for a minute and a half then initiated a "seek". Did your player go into standby for a minute? Or is it lots of synched players gradually getting out of synch and trying to correct themselves by rewinding?

So I'm assuming you are experiencing that fix. If you set the the logging level to warning you should be able to see the retries kicking in. The problem is caused by the way that LMS performs asynchronous http calls, they can be blocked intermittently on some setups, you probably don't notice it in most scenarios, but the way that the bbc streams in chunks with a new connection every 6 seconds it becomes very visible.

I feeel the root of "drop outs" was these "long delay" packets. I think it is has virtually disappeared for you because 1. BBC Sounds is a new plugin and stream handling is also new. There are improvement/fixes being made to the code - one of which I know dealt with "long delay". This means when it happens, its effect is minimised - you'll only notice the really really long delayed packet. 2. A local/regional network issue has been resolved. I had a version of plugin to log these "long delay" packets - from my experience and other users reporting - it often happened at weekends and/or in a region. My guess is that the "long delay" packets happen more often when a network upgrade/maintenance is happening or if there is regional network issue affecting the CDN network. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] BBC Sounds Dropping out
OK So done various tests as my base I ran 8 hours solid music streaming from my NAS to the 3 synchronised Raspberry Pi's and as expected I got no drop outs or any other issues so internal networks and devices appear to be functioning correctly, then did the same with Listen Again and had no issues, doing the same with Live feed Radio 2 I had one occasion of loss of sound of a couple of seconds with nothing showing in the log files and at this level it is not even a minor irritant. So what has changed and the only thing I can identify is upgrading to Sounds 2.9.1. The one thing I did notice was that the log file when on Live appeared very similar to that of Listen Again whereas previously the number of requests per second was significantly different I will keep monitoring and get back to you. If it would help I can send log files if anyone cares to specify what they would like to see. Thank you for help and as always in such circumstances I am frustrated that I cannot come up with an explanation or put my finger on one issue that could be further investigated.

Feels like a bit of progress. Live streams will be more sensitive to chunk delays so if drop outs are more frequent with Live stream then the problem is likely to be related to chunk delays. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

So it is triggering for each chunk, each of which is a GET which requires a DNS lookup. Each chunk is about 6 secs long so gaps of secs for each DNS lookup would be right. The "internet radio" logging is not suited for the BBC Sounds DASH streams. There is plugin specific logging with plugin.bbcsounds but INFO level also generates a lot of messages so unless problem happens quicky log file gets very big. If there is an error the BBC Sounds plugin should log it. What does the log look like with default logging settings.

Did you enable any logging for these "resolve" message to appear in the log ? Is this an edited log file with message or text removed ? if so then please post unedited log file (zip & attach) as sometime the message that are missing are important. What do you mean "Yes I have proxy set because I synchronise my units" ? The Direct / Proxued streaming setting is ignored if a player is sycned with other player - so the reason for "proxy" is unclear. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Not sure which UI you are using. On a WebUI the displayed timer is driven by web based code and corrected by LMS. The above description seems to indicate an interruption in network connection. BBC Sounds plays DASH streams where audio is broken into small "files" (3 sec I think) - sometime these files have a "pause" due to network and there was BBC Sounds fix about 3 weeks ago for this. Can you test to see if you get this problem with a "listen Again" stream ? "Listen Again" enable buffers to be filled so if it is the network problem - the "gaps" should not occur. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] BBC Sounds Dropping out
Always good to detail the version you're running. If not the latest version then it is hardder to give advice. Are you using any special DACs or using any non default LMS settings (e.g. disabling AAC native) Are you in the UK or outside UK. If outside the UK are you using a VPN ? More specific details on the problem will also help. "dropouts" - are these gaps of silence inserted into the audio stream or gaps of silence where audio is lost ? Does the problem happen with only "Live" , only "Listen Again" or both "Live" and "Listen Again" ?

[SlimDevices: Plugins] BBC Sounds Dropping out
Hi I am having a problems with the BBC Sounds in terms of dropping out fairly often. My system includes a Pi 3 as PcP based LMS Server only hardwired and 3 Pi 2's all wifi various output options all using PcP have happily run for a number of years streaming music from my NAS, did use BBC Iplayer but got tired of the dropouts and other problems (for various reasons) and not used for several years. Now trying out Sounds and getting some dropouts looking for advice on how trace the cause. To eliminate the router I have a Pi 4 on the wifi on which I have run BBC Sounds via the Chromium Browser to a bluetooth speaker for hours without a single dropout. So thinking settings in LMS which I have forgotten/not found, which logs should I run to track the faults have completely forgotten. Can anybody point me at a Wiki or similar on setup and fault finding Regards Phil comeng's Profile: http://forums.slimdevices.com/member.php?userid=63874 View this thread: http://forums.slimdevices.com/showthread.php?t=113563 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
