Dynamically add tabs to the transcoder settings page. Use the same
mechanism that is used in the options dialog to select an options
page based on the best encoder element for a mime type.
Create a TranscoderOptionsError class and ui that inherits from
TranscoderOptionsInterface. Use this to display options errors. Move
widget creation into a static method. These changes will allow use of
the same mechanism in the transcoder settings page.
Split best element type search from Transcoder::CreateElementForMimeType
into new FindBestElementForMimeType method. This will allow the setting
dialog to determine the encoder element type before the pipeline is
built.
Remove condition that allows no dialog to be displayed when user selects
options for transcoding. Display the dialog with an error message
instead. This also applies to the transcode options dialog in the
ripping and network remote settings.
The gstreamer flacenc element defines a set of quality levels that is different
from the standard flac library. Its highest level, labeled "insane", uses
settings that are outside of the streamable subset. Set the streamable-subset
property to false for this level.

This allows the use of the DumpGraph method in transcoding pipelines. The call
can be added to Transcoder::StartJob for debugging. In the future, a trigger
may be added to the debug console ui.
A bit more information:
Normal transcoding worked fine, the transcoder object was in the main thread. In the network remote, a new transcoder object is created which runs in the network remote thread. When a song was transcoded there, the UI became unresponsive.
Removing the async bus callback solved the problem, exactly the g_source_remove() method caused it. Since the bus callback returned FALSE (GST_BUS_DROP), the watch was already removed. (See http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBus.html#gst-bus-add-watch)
- It is configurable in the settings.
- Any format can be chosen that is supported by the transcoder.
- The status of the transcoder is send to the remote.
- Transcoder format settings have now a postfix so we can define mutliple transcoder formats and use them separatly. Here one for the normal transcoder and one for the network remote transcode. You can pass the postfix in the constructor.
- Fixed Transcoder crash (was introduced with the gstreamer1.0 merge, decodebin doesn't have a "new-decoded-pad").
- Transcoder emits the output filename as well on "JobComplete" signal
- Transcoder can now convert a file to a temporary file ("AddTemporaryJob")
