   1 youtube-dl (2015.05.15-1) unstable; urgency=medium
   2
   3   Starting with Debian's version 2015.05.15-1, the handling of video
   4   formats has been revamped in youtube-dl.  In particular, the option
   5   `--max-quality` doesn't exist anymore.  This is likely to break scripts
   6   and/or other programs that use this option.
   7
   8   Please, refer to the manpage (in particular to the section named
   9   "FORMAT SELECTION") for more details.

  14
  15   There are too many goodies that this new release brings us,
  16   including that it is possible to combine/merge/multiplex audio and
  17   video formats that Youtube now offers separately (See the previous
  18   notes about Youtube using DASH for video and audio).
  19
  20   Now, if you want a 480p video in H.264 format, High profile, with
  21   128kbps AAC audio (this used to be Youtube's format 35), you can
  22   specify format `-f 135+140` on the command-line, and so on. Only your
  23   imagination is the limit.

  31
  32   From http://cynic.cc/blog/posts/2013-10-23-assorted_news/:
  33
  34    [13]Some people may have noticed, others may not, but when downloading
  35    videos from Youtube, they apparently are getting more aggressive with
  36    the use of [14]Dynamic Adaptive Streaming over HTTP (also called DASH)
  37    and, as a result, some (perhaps going to be all in the near future?) of
  38    the videos may not be available in the resolution/formats that you used
  39    to like (like me, with format number 35).
  40
  41    By the way, one thing that is interesting with youtube videos provided
  42    via DASH is that they are available in different streams: one for the
  43    video and another for the audio.
  44
  45    What does this mean in practical terms for users of youtube-dl? Well,
  46    if you wanted to download videos in resolutions like the 480p (format
  47    35) that I mentioned, then you will probably have to change your way of
  48    doing things, until a more automated solution is in place.
  49
  50    You will have to download both the audio and the video and, then,
  51    "combine" them (that is, multiplex them) to create one "normal" video
  52    file with both the audio and the video. I usually do this via:
  53
  54    ffmpeg -i audio.m4a -i video.mp4 -vcodec copy -acodec copy combined.mp4
  55
  56    If you prefer having a Matroska container instead of an mp4 container
  57    (which, BTW, results in smaller muxing overhead), then you can use the
  58    command line:
  59
  60    mkvmerge -o combined.mkv audio.m4a video.mp4
  61
  62    Oh, those m4a and mp4 extensions are a new addition that [15]I just
  63    sent upstream (in the past, both would have been named with an
  64    extension of mp4).
  65
  66    As, an aside, I like formats 135 for video and 140 for audio, for the
  67    reasons that I mentioned in a comments to issue 1612:
  68
  69      Otherwise, to download 480p videos (which I do for lectures and so
  70      on with other projects of mine, like edx-dl) I have to call
  71      youtube-dl twice: once for format 135 and another for format 140,
  72      since the old (?) format 35 files are much smaller than the lower
  73      resolution 360p files (due to the former being encoded in High
  74      profile vs. the latter being encoded in Constrained Baseline
  75      profile).
  76
  77    While this is unfortunate for some, this is a good thing for others: I
  78    once had a blind user of youtube-dl asking me if he could avoid
  79    downloading the whole video just to extract the audio, so that he save
  80    on bandwidth. Well, now this is possible.

  91   The upstream author has removed support for the -b ("best format") and
  92   the -d ("high def") command line options.
  93
  94   The behavior now is to download the best quality for each video.
  95   If you experience a problem with youtube-dl downloading videos that are
  96   too large, you should consider using the --max-quality option to limit
  97   which format to use.
  98
  99   The list of formats (in decreasing quality) can be found with:

 101       grep "available_formats =" /usr/bin/youtube-dl
