The fix works fine. Album and Artist thumbnails are being retrieved now even where there are empty tags.

[Bug 1512608] Re: No thumbnails generated for OGG audio
If you try with your own collection and scan the log, if you find a bad request followed by loads of "failed previously", we are dealing with the same issue. If not, I'd still like to get my hands on your collection, but let's hold off with that for now. I'm working on a fix at the moment. The problem is caused by the music app asking for artist art with an empty artist tag, and asks for album art with an empty album tag. For those, the remote server returns a bad request response. In turn, that sends the thumbnailer into an error handling path where it it incorrectly concludes that the server has returned something silly that should not normally happen (such as an internal server error) and then stops trying to talk the server for two hours. The ultimate cause of the problem is a poorly-designed Qt API that, for a 400 response, returns a totally unexpected and counter-intuitive error code. I should have fix ready today, but it won't become available until OTA-9, I'm afraid. In the mean time, if that is feasible, check whether you can find any songs in your collection with an empty artist or empty album field. Setting these empty fields to something non-empty should fix the problem (if the issue you are seeing is indeed the same one as for my test data set). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512608 Title: No thumbnails generated for OGG audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/music-app/+bug/1512608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK, probably no need for the flash card, I think I have reproduced the problem. I'm attaching an archive that contains 7000 MP3 files, in subdirs of 1000 files each. Each MP3 is one second of silence, with exactly two tags, album and artist. The tags were created from server trace files (thanks Facundo!); they all have corresponding artwork in 7digital. Once mediascanner has done its thing, when I start the music app, I end up with lots of Bad Request responses from the server. Not sure why yet.

[Bug 1512608] Re: No thumbnails generated for OGG audio
Hi Michi, thanks for the interest! The experience was interesting. After the upgrade I went into the Music app. It was interesting to watch as all the entries dispersed in front of my eyes :-% After a few application restart the Music app simple crashed on startup. Quick solution to this was simply to uninstall and reinstall it so it started in a fresh state. I assume problems in the media scanner here. After reinstall the thumnnailer churched away and over a time and managed to get about 50% thumbnail coverage (no correlation to .mp3 or .ogg format). Dbus logs showed quite a number of network error responses from the thumbnailer. On subsequent runs you see the corresponding FAILED PREVIOUSLY responses. Since there about 400 artists and 600 albums the behaviour seems reasonable assuming the backend server was not responding in time to all requests. To speed things up I did a 'thumbnailer-admin clear f'. After a bit more thumbnailer churning it reached about 100% coverage of the albums and artists I would expect to be known. So good so far, until yesterday. Before giving you an update I open up the music app. To my surprise no thumbnails where shown (blank squares not grey heads or grey quavers). Looking at the dbus logs showed 10s timeouts and I think a crash report from thumbnailer. Annoyingly my pastebin upload of the dbus.log from the Logviewer app failed. After a reboot the thumbnaiker started to pull new thumbnails from scratch. I not quite sure what trigger the thumbnailer to purge (or loose) its image cache. Sorry for the lack of concrete information, I hope you enjoyed the story however.

Hi Fred, thank you for taking the time to help diagnose this! > On subsequent runs you see the corresponding FAILED PREVIOUSLY responses. Since there about 400 artists and 600 albums the behaviour seems reasonable assuming the backend server was not responding in time to all requests. Hmmm… We rate-limit the requests we send to the remote server such that there are never more than two requests in progress concurrently. So, nothing should ever time out at the HTTP level unless the server truly didn't respond. (We will not mistake a long wait time before we can send a request for a timeout.) At any rate, the FAILED PREVIOUSLY log entries indicate that this was a genuine authoritative "no artwork available" response. Most likely, some of your songs are for artists and/or albums for which the remote server has no artwork. You can verify this by using curl: curl "https://dash.ubuntu.com/musicproxy/v1/album- art?artist=nosuchartistalbum=nosuchalbumkey=0f450aa882a6125ebcbfb3d7f7aa25bc" >/tmp/out Replace "nosuchartist" and "nosuchalbum" with the (percent-escaped) details. If you have a thumbnailer crash, I'd be keen to get my hands on it. Is there anything in /var/crash? Not sure what's going on with the music app. It might be an unrelated issue. The thumbnailer will not ever purge its cache, unless it detects database corruption, in which case it reinitialises the DB. But you would see definite trace in the log for that. I'm afraid that the best way for us to move this forward would be for us to get our hands on your music collection. I'm looking at ways to create artificial test data for such stress testing too, but it's going to be tedious, and I want to make sure that we are getting a reproducible test case.

Fred, thanks for getting bad to us! If the music app gets killed, it might be because it asks for more than it can eat. If it sends a large number of requests to the thumbnailer, and lots of requests get a cache hit, the thumbnailer will deliver close to a thousand images per second, which can eat a lot of memory. I suspect that the retry in the thumbnailer is not going to fix this. This sounds more like a scalability issue outside of the thumbnailer to me. The SD card option would be ideal. I thought about doing something with my own music library, but all of my songs have embedded cover art in them, and it would take me an eternity to strip out all the cover images.

Thanks for the update, Fred! If one of the files causes a crash or hang during extraction, the thumbnailer is robust against that and will kill off the offending process.

Indeed possible. I wondering if the large number (and possibly large size) was indirectly the cause. Possible one of the many an varied OGGs I have cause a thumbnailer crash or hang. I will investigate this later. What is strange is that I previously I had no thumbnails on OGGs and a high proportion of thumbnails on the few MPs I have. I did a) Cleared the thumbnailer failure cache b) removed the whole thumbnail cache directory c) Removed and reinsterted the SD card d) Uninstallled and reinstalled the core Music app After each change I gave the music app/thumbnailer a day or two to get more thumbnails, scrolled about a lot, open and closed the music app. The convergent result at the end was always the same files (MPs) having thumbnails!

[Bug 1512608] Re: No thumbnails generated for OGG audio
I'm pretty sure that there is nothing wrong with extraction from ogg files; we have tests for this. But, if most of these files do not contain artwork and you add an SD card with thousands of songs and run up the music app, the music app will send hundreds of requests to the thumbnailer. No problem, the thumbnailer queues them all up and patiently grinds through them. However, for each file without embedded artwork, the remote server has to deliver an image. This is slow. So slow that, in all likelihood, some of those requests will time out in the app because they will spend more than 30 seconds in the queue before the thumbnailer even sends the request for the image to the server. Again, no big deal. The server will reply eventually, and the thumbnailer will cache the image. But the calling music app may well get tired of waiting and show you the "no artwork" default image instead. However, if you scroll around in a song list or the like, as soon as you move away from a missing thumbnail far enough and scroll back to it, the app will re-issue the request for the thumbnail. That second request will be answered instantly because, by now, the thumbnailer will have the image in the cache and deliver it in about a millisecond. So, I'm wondering whether what you are seeing is simply due to the fact that a lot of files are added at once, and it simply takes quite a while to fetch the thumbnails for all of them? The other possibility is that, at the time you tried, the remote server had a problem, in which case we back off and stop asking the server again for two hours.

[Bug 1512608] Re: No thumbnails generated for OGG audio
Just cut down to just a few files on the sdcard and managed to get a thumbnail hit on an OGG file. So you should not see a problem with the OGG gile I attached, I'll expand the trials a little to see if I can actually find the failure mode. I normally have several thousand files! I'll try and get something more concrete to you before OTA-8 comes out! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512608 Title: No thumbnails generated for OGG audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thumbnailer/+bug/1512608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1512608] Re: No thumbnails generated for OGG audio
OGG audio file attached. Rhythmbox shows following tags: Title: A Whiter Shade of Pale Artist: Annie Lennox Album: Medusa Album Artist is empty. I'm going to try if setting this helps the thumbnailer. This evening (UTC) I will cut down the music collection on the sdcard to just a few files, clear caches etc, so I can see what happing in the logs. ** Attachment added: "OGG audio from a well known Artist" https://bugs.launchpad.net/ubuntu/+source/thumbnailer/+bug/1512608/+attachment/4512536/+files/a_whiter_shade_of_pale.ogg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512608 Title: No thumbnails generated for OGG audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thumbnailer/+bug/1512608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
