v0.2.5

• New commandline arguments --prefer-video-width and --prefer-video-height which allow the user
  to specify the video stream to be downloaded, when multiple video streams with different
  resolutions are made available. The video stream with the horizontal (respectively vertical)
  resolution closest to the specified width (respectively height) is chosen. This preference only
  concerns the video stream; use the --quality commandline argument to specify the preferred audio
  stream when multiple audio streams with different quality levels are available. If a preference
  for both video width and video height is provided, the preferred width is used. A width or height
  preference overrides (for the video stream) a specified quality preference.

• New value intermediate recognized for the --quality commandline argument. If the DASH manifest
  specifies several Adaptations with different bitrates or quality levels (specified by the
  @qualityRanking attribute in the manifest -- quality ranking may different from bandwidth
  ranking when different codecs are used), prefer the Adaptation with an intermediate bitrate
  (closest to the median value).

• New commandline arguments --auth-username and --auth-password to specify the username and
  password to be used for authentication with the server. Currently only HTTP Basic authentication
  is supported.

• Improve support for selecting the output container format based on its filename extension.
  Selecting an output file with an .mkv extension will now produce an output file in Matroska
  container format, even in cases where the manifest only contains a video stream or only an audio
  stream (shortcircuiting the muxing functionality). In these cases, the stream will be copied if
  the output container requested is compatible with the downloaded stream format, and otherwise a
  new media container with the requested format will be created and the audio or video stream will
  be inserted (and reencoded if necessary) into the output file. This insertion and reencoding is
  undertaken by the same commandline applications used for muxing: ffmpeg, mkvmerge, mp4box
  (currently not vlc).
