The MEDIA_ERR_SRC_NOT_SUPPORTED error is probably a consequence of the error just above, "No data received".

Note that I can reproduce the same error on desktop by browsing to e.g.!/popular and clicking any song in the list.

Setting "preferences.localStorageEnabled: true" on the webview makes the localStorage read/write errors go away, but doesn’t fix the playback issue.

Using wireshark to monitor the network traffic, I can see that the track is requested and correctly sent by the server.
It looks like the problem is with the file format, apparently MP3 is not supported by default.

This is evidenced by this very simple HTML test page:

        <audio controls autoplay>
          <source src="test.mp3" type="audio/mpeg">

which doesn’t play, however if I replace the source by <source src="test.ogg" type="audio/ogg"> then the audio plays.

More info from Chris:

<oSoMoN> chrisccoulson, what would it take to enable support for mp3 for the audio tag by default in oxide?
<chrisccoulson> oSoMoN, basically, we need 2 build steps (the current one and one with proprietary_codecs=1), so that libffmpeg can be built twice
<chrisccoulson> the chromium source package does something like this, but it actually gets it a bit wrong (it breaks incremental builds for some reason)
<chrisccoulson> i think because it reconfigures gyp after building chromium to build ffmpegsumo a second time with h264/mp3

Chris Coulson (chrisccoulson) wrote :

Adding a packaging task for Oxide as well - if we add an option to oxide for enabling proprietary codecs, and we can change that option without forcing a rebuild of the entire tree (not sure about that), then the 2 build steps could be added to the packaging by running cmake, building, re-running cmake and then doing an incremental build

Chris Coulson (chrisccoulson) wrote :

Ok, the incremental build won't work, as setting the proprietary_codecs flag in gyp changes a compiler definition in build/common.gypi which is applied to every source file in the tree, resulting in a full rebuild :(

This bug was fixed in the package oxide-qt - 1.0.0~bzr490-0ubuntu1

oxide-qt (1.0.0~bzr490-0ubuntu1) trusty; urgency=medium

  * Update to r490
    - Build with enable_plugins: 0 and toolkit_views: 0 to trim the size
      a bit
    - Ensure subframe navigations that require a new window become top-level
      navigations for webviews that don't implement WebView.newViewRequested
    - Add an option for enabling proprietary codecs (ENABLE_PROPRIETARY_CODECS)
    - Build and install the l10n pak files
    - Add file picker support (LP: #1260008)
    - Add some resources to oxide.pak that were missing (eg, directory listing
    - Fix a crash that occurs when handling events from some mouse buttons
    - Add cursor support (LP: #1257662)
    - Reimplement Chromium's RenderSandboxHostLinux so that it runs the sandbox
      IPC helper process as a proper child process rather than just forking
      the browser process, which is dangerous for Oxide (LP: #1304648)
  * Split in to 2 separate packages (oxideqt-codecs and
    oxideqt-codecs-extra) (LP: #1301341)
