Interesting, Andy is still watching :) as he accepted this PR. So he did not accept the other one probably because he disagrees, I'll ask him. At this point, it's not mandatory as I've done an dirty workaround but I could easily use it w/o impacting compatibility. Depending on Andy's response, we might use that 2nd PR or not.

Re: [SlimDevices: SqueezeCenter] LMS playback time problem
Well, "moving the time slider to within a few seconds of the end of a track" is only the condition that I found problem occurs. LMS is an awesome software and I found it seems to have problem of playback synchronization, like Spotify Connect, hires music files playback...

Re: [SlimDevices: SqueezeCenter] LMS playback time problem
Thanks philippe_44 for detailed explanation the LMS! I learn so much from your reply. I am surprised that there is a difficulty for LMS to determine the accurate position of music file. I am not familiar with music streaming, so I could not give an useful technical suggestion. I describe more situation for your reference. In the example of jump to the last 10 seconds of the track, the music will keep playing after the slider ends. The slider will wait for seconds or minutes even after the music reach the end(with no sound). Sometime the waiting time is not short. I feel that it seems to play the whole music time after time jumping(not very sure). I hope these experience could be helpful. " seeks N bytes into the file" may be the key problem. Maybe it's difficulty to determine the "precise" byte position. On the other hand, about the sentence "file format and how that file has been created", my music files are apple m4a format and flac format , which are created using Apple itunes or foobar2000. philippe_44 wrote: > For many formats, it is not possible to have a precise "jump to > position" because the bitrate is not constant or the seektable is not > granular enough.

Agree. I also can't see the point in moving the time slider to within a few seconds of the end of a track, why not just skip to the next track? Anyone with a Squeezebox with a VDF display can set up the screen to show a variety of different elements, one of which shows buffer fullness. Video below shows the buffer fullness falling as it reaches the end of a track (top line extreme left). At 10 seconds from the end of a track the buffer is empty and starts to fill for the next track. Probably another reason why the time display can never be accurate so near the end of a track. https://youtu.be/gHxwtAiAPGM *Server - LMS 8.3.0 *Pi4B 4GB/Argon one case/pCP 8.0.0 - 75K library, playlists & LMS cache on SSD (ntfs) *Study -* Pi4/pCP 8.0.0/Topping E30 DAC/Ruark MR1 Mk2 *Lounge* - Pi2/pCP 8.0.0 > HiFiBerry DIGI+ > AudioEngine DAC1 > AVI DM5 *Dining Room* - Pi3B/pCP/Bluetooth/Echo Show 8 *Garage* - DAC32 > Edifier speakers *Spares* - 2xTouch, 1xSB Radio. 1xSB3, 6xRPi kidstypike's Profile: http://forums.slimdevices.com/member.php?userid=10436 View this thread: http://forums.slimdevices.com/showthread.php?t=114937 ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter

For many formats, it is not possible to have a precise "jump to position" because the bitrate is not constant or the seektable is not granular enough. In addition, the time reported by LMS on the UI is not perfect. It is the estimation that LMS does, added to the playback time reported by the player. Players do *not* report absolute time (they don't know it), but how many milliseconds they have been playing since the last request. So when you seek to a position P in seconds, LMS stops playback, seeks N bytes into the file to its best estimation of where is P seconds and starts sending a *new* track to the player from byte N+1. LMS then starts to count time from the estimated position using an autonomous counter and adjust that counter when it receives the player's actual played time which has started at 0 second with first bytes received, so at byte N+1 of the actual file This explain why playback counter it often not very precise, it's just an indication sometimes and especially jumping 10s before the end of a track is unlikely to display things properly.

Re: [SlimDevices: SqueezeCenter] LMS playback time problem
I had played several 96/24, 192/24 albums(in apple lossless m4a format) and I found that there was a time calculation problem with LMS while I moved the playback slider. For example, I moved to last 10 seconds, the playback was also changed.(maybe wrong time location) 10 seconds later the playback ended while the music still went on. The playback slider kept waiting until the music really ended. This issue is not happened if I play 44.1 album and it's also fine with Qobus hires music. Therefore, I think the problem is quite clearly. Hope these experiences could be helpful. Thanks ! mherger wrote: > > 1.

Re: [SlimDevices: SqueezeCenter] LMS playback time problem
1. Track time synchronization problem with Hires music file : It's only happen with hires music file (>44.1). The track time is not correct with the actual time while I jump the track time location. If I change the What file format are you using? Are these local files? Would you have exact steps to reproduce the issue? 2. Spotify connect problem : With using spotify connect, while I move Spotty/Spotify Connect unfortunately is a bit fragile. In particular the time display in the Spotify apps can indeed be out of sync by several seconds. It's a known limitation. ___ Squeezecenter mailing list Squeezecenter@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/squeezecenter
