2
3 Starting with Debian's version 2015.06.04.1-1, 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.

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.

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.

99 The list of formats (in decreasing quality) can be found with:
