+ There are too many goodies that this new release brings us,
+ including that it is possible to combine/merge/multiplex audio and
+ video formats that Youtube now offers separately (See the previous
+ notes about Youtube using DASH for video and audio).
+
+ Now, if you want a 480p video in H.264 format, High profile, with
+ 128kbps AAC audio (this used to be Youtube's format 35), you can
+ specify format `-f 135+140` on the command-line, and so on. Only your
+ imagination is the limit.
+
+ See http://cynic.cc/blog/posts/2014-02-17-youtube-dl_news/ for more
+ verbose news.

+youtube-dl (2013.10.23-1) unstable; urgency=low
+
+ From http://cynic.cc/blog/posts/2013-10-23-assorted_news/:
+
+ [13]Some people may have noticed, others may not, but when downloading
+ videos from Youtube, they apparently are getting more aggressive with
+ the use of [14]Dynamic Adaptive Streaming over HTTP (also called DASH)
+ and, as a result, some (perhaps going to be all in the near future?) of
+ the videos may not be available in the resolution/formats that you used
+ to like (like me, with format number 35).
+
+ By the way, one thing that is interesting with youtube videos provided
+ via DASH is that they are available in different streams: one for the
+ video and another for the audio.
+
+ What does this mean in practical terms for users of youtube-dl? Well,
+ if you wanted to download videos in resolutions like the 480p (format
+ 35) that I mentioned, then you will probably have to change your way of
+ doing things, until a more automated solution is in place.
+
+ You will have to download both the audio and the video and, then,
+ "combine" them (that is, multiplex them) to create one "normal" video
+ file with both the audio and the video. I usually do this via:
+
+ ffmpeg -i audio.m4a -i video.mp4 -vcodec copy -acodec copy combined.mp4
+
+ If you prefer having a Matroska container instead of an mp4 container
+ (which, BTW, results in smaller muxing overhead), then you can use the
+ command line:
+
+ mkvmerge -o combined.mkv audio.m4a video.mp4
+
+ Oh, those m4a and mp4 extensions are a new addition that [15]I just
+ sent upstream (in the past, both would have been named with an
+ extension of mp4).
+
+ As, an aside, I like formats 135 for video and 140 for audio, for the
+ reasons that I mentioned in a comments to issue 1612:
+
+ Otherwise, to download 480p videos (which I do for lectures and so
+ on with other projects of mine, like edx-dl) I have to call
+ youtube-dl twice: once for format 135 and another for format 140,
+ since the old (?) format 35 files are much smaller than the lower
+ resolution 360p files (due to the former being encoded in High
+ profile vs. the latter being encoded in Constrained Baseline
+ profile).
+
+ While this is unfortunate for some, this is a good thing for others: I
+ once had a blind user of youtube-dl asking me if he could avoid
+ downloading the whole video just to extract the audio, so that he save
+ on bandwidth. Well, now this is possible.

+youtube-dl (2010.07.22-1) unstable; urgency=medium
+
+ The upstream author has removed support for the -b ("best format") and
+ the -d ("high def") command line options.
+
+ The behavior now is to download the best quality for each video.
+ If you experience a problem with youtube-dl downloading videos that are
+ too large, you should consider using the --max-quality option to limit
+ which format to use.
