Resulting Flac files cannot have their tags edited in Synology Audio Station

[Jean-Philippe Baril]

I converted wav files into flac files then put the flac files on my Synology NAS.

In the Synology Audio Station webapp if I try to edit the file tags I get an error and the tags are not saved. Audio Station sees the files and can play them thought. The problem really seems to be with the tags.

If I convert the wav files with "flac" command line I can edit the resulting flac files in Audio Station webapp.

I have a tone a flac files from different sources/encoders on my NAS and it's the first time I get such error.

I'm using 2.9.0-beta1 on Ubuntu 16.04

SoundConverter does nothing special concerning tags.
So, this can be an issue with GStreamer, but it seems unlikely.
Are you sure this is not a file writing right issue ?

I'm having trouble with Elisa (and Dolphin) recognizing tags that I set (using Kid3) on flac files created using SoundConverter, and it may be related to this bug. I'm able to set flac metadata normally on flac files created with other programs (like the flac command or Audacity.)

I have confirmed this appears to be a GStreamer issue, and I've opened an issue with gst-plugins-good here: https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/756

In short, flac files created with gst (and, by extension, SoundConverter) seem to always have an empty SEEKTABLE metadata block (the block is present, but has a length of 0 and contains 0 seek points.) This seems to only happen when the source is a wav file.
