It would be nice to have all the important dates in one place.

1) Release schedule 2) Contributor meetings 3) Bi-weekly bug triage 4) Any hackfests or conferences we participate in

The quick and dirty fix: Wiki page with manual dates, easy but likely to become uncurrent

The more robust fix: Something like this, ​http://www.mediawiki.org/wiki/Extension:Calendar_%28Cdamian%29 A bit more work to set up, but since it integrates with other calendars, it may help us retain more contributors in the long run by helping people remember meetings and deadlines.

A user is uploading a number of ogg video files to my instance (videos with .ogg extension). These files transcode fine, which makes me think I have the correct python bindings for ogg files, but they hang at the thumbnail stage. Once this happens, that celery worker becomes stuck waiting and cannot be used for anything else. When enough of these files get uploaded and processed, all of my celery workers become stuck and nothing else proceeds. I have to restart my celery service to kill the stuck workers and make them available for use again.

I added a bunch of debug logging statements and tracked it down to the following line in mediagoblin/media_types/video/transcoders.py.

sample = appsink.emit("pull-preroll")

Online gst documentation says that pull-preroll may block until the preroll buffer or EOS signal is received, which appears to be happening on my instance with these video files.

The normal way of retrieving samples from appsink is by using the gst_app_sink_pull_sample() and gst_app_sink_pull_preroll() methods. These methods block until a sample becomes available in the sink or when the sink is shut down or reaches EOS.

If a blocking behaviour is not desirable, setting the "emit-signals" property to TRUE will make appsink emit the "new-sample" and "new-preroll" signals when a sample can be pulled without blocking.

The "caps" property on appsink can be used to control the formats that appsink can receive. This property can contain non-fixed caps, the format of the pulled samples can be obtained by getting the sample caps.

If one of the pull-preroll or pull-sample methods return NULL, the appsink is stopped or in the EOS state. You can check for the EOS state with the "eos" property or with the gst_app_sink_is_eos() method.
