2. get_flash_videos reverts to a 'generic' method
3. No video is downloaded
What is the expected output? What do you see instead?
The video should be downloaded.
What version of the product are you using? On what operating system?
git master, commit 1538eeae6e6e3c2d7a3689bf4c0431d45759e1f0
Please provide any additional information below.
Normally I would write a patch for something like this, but I don't have time
right now. In the meantime, it is relatively easy to script the downloads in
bash and join the segments by hand. The files are unencrypted and the URLs can
be easily extracted from the HTML, so I'm providing instructions below.
Download the following Discovery.com show page:
http://dsc.discovery.com/tv-shows/gold-rush/videos/the-long-road.htm
There will be some JSON which includes a list of clips. The '"m3u8": ' items
are the interesting bits. These might be multiple short 1-2 minute clips, and
there will be one much longer clip (~42 minutes). In the above case:
http://discidevflash-f.akamaihd.net/i/digmed/hdnet/35/f8/02652500201001_GR_Long_
Road-,400k,110k,200k,600k,800k,1500k,3500k,.mp4.csmil/master.m3u8
is the one we're interested in. Downloading the referenced file, we get a text
file with several lines like this:
....
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=3560000,RESOLUTION=1280x720,CODECS="avc
1.77.30, mp4a.40.5"
index_6_av.m3u8?e=b471643725c47acd
....
Concatenate the base of the above URL with the a requested playlist to get (in
this case the HD stream):
http://discidevflash-f.akamaihd.net/i/digmed/hdnet/35/f8/02652500201001_GR_Long_
Road-,400k,110k,200k,600k,800k,1500k,3500k,.mp4.csmil/index_6_av.m3u8?e=b4716437
25c47acd
Downloading this file, we finally get the playlist:
#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-ALLOW-CACHE:YES
#EXT-X-VERSION:2
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:10,
segment1_6_av.ts?e=b471643725c47acd
#EXTINF:10,
segment2_6_av.ts?e=b471643725c47acd
#EXTINF:10,
...
etc
In the case of the above HD stream, each segment will be about 4-5 megabytes
and there could be upwards of 250 of them. These segments are parts of an mpeg
transport stream, and seem to be safe to blindly concatenate. They are
identified by ffmpeg as follows:
Input #0, mpegts, from 'ts/segment99_6_av.ts?e=b471643725c47acd':
