Android Question Exoplayer Youtube Dash

[FrankDev]

hi

i've problems to get the 'real clear' dash string for YouTube videos.

like
sources.Add(player1.CreateDashSource("http://www.youtube.com/api/manifest...6521BFC350652163895D4C26DEE124209AA9E&key=ik0"))

i try:
1. get the Video info / like (http://www.youtube.com/get_video_info?&video_id=a1D6xizxLXg)
2. urldecode the http_answer
3. search for a key called 'dashmpd'

found the key but there isn't a 'clear string' ?!?

 

[Erel]

Have you found any documentation about this? Where does this link come from?

 

[FrankDev]

first link is from your example.
https://www.b4x.com/android/forum/threads/exoplayer-mediaplayer-videoview-alternative.72652/

the 'how to' from stackoverflow
http://stackoverflow.com/questions/29607104/how-to-play-youtube-video-in-exoplayer-in-android

 

[Erel]

1. Find dashmpd=
2. Find the next &
3. Now URLDecode the substring once or twice (test it).

Hi Erel,

tested it before i wrote to the forum about 10 times - but i always get string like...

sources.Add(player1.CreateDashSource("https://manifest.googlevideo.com/ap...layback_host/r3---sn-4g5e6nez.googlevideo.com"))

sources.Add(player1.CreateDashSource("https://manifest.googlevideo.com/ap...A59E2C28DE1AFC105FF0468FD/source/youtube/mv/m"))


not as 'short' as in your example.

 

[Erel]

It doesn't matter. The long url works. I've just tested it:

sources.Add(player1.CreateDashSource("https://manifest.googlevideo.com/api/manifest/dash/mm/31/mn/sn-jjjpa-ua8e/id/o-APfz9Vyd_6uCFgmQvD7i4VPYvn_hVMWfBjTFBs2zfO5J/mt/1484545841/sparams/as,hfr,id,initcwndbps,ip,ipbits,itag,mm,mn,ms,mv,pcm2cms,pl,playback_host,requiressl,source,expire/mv/m/ms/au/ip/5.144.60.34/as/fmp4_audio_clear,webm_audio_clear,webm2_audio_clear,fmp4_sd_hd_clear,webm2_sd_hd_clear/playback_host/r1---sn-jjjpa-ua8e.googlevideo.com/hfr/1/pl/24/upn/LagJhAtaOlQ/source/youtube/expire/1484567634/pcm2cms/yes/ipbits/0/signature/86DA4825B2E3B1B0313C0BC2E41B391FE23AEDAC.0ACF62D058ED34122672F3A7E999689D121E8CA6/itag/0/key/yt6/requiressl/yes/initcwndbps/1797500"))

I tested both copyrighted and non copyrighted video, it not work with copyrighted video.
exoplayer response error 403.

 

[FrankDev]

Don't work with 'LIVE' videos

 

[FrankDev]

Another problem!
the Video-Size is always 640 ?!?

Possible to set 1080 ?

1. Find dashmpd=
2. Find the next &
3. Now URLDecode the substring once or twice (test it).

is it possible to get the link using httpjob like this?

Dim j As HttpJob
   
    j.Initialize("urlstream", Me)
   
    j.Download2("http://www.youtube.com/get_video_info",Array As String("video_id",videoid))

because if i follow the link above through the browser it always download "get_video_info" file.

 

[Erel]

Yes, it is possible. You need to parse the response as explained in post #4.

 

[Leni Berry]

Yes, it is possible. You need to parse the response as explained in post #4.

with this code :

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    'https://www.youtube.com/watch?v=cgxWP4Wu77s
    Dim j As HttpJob
    Dim videoid As String="=cgxWP4Wu77s"
   
    j.Initialize("youtube", Me)
    j.Download2("https://www.youtube.com/watch",Array As String("v",videoid))
   
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub JobDone(job As HttpJob)
    Log(job)
    Log(job.GetString)
    job.Release
End Sub

the output is not the same with file downloaded when access through browser...

how can i parse the content?

 

[Erel]

You need to parse the get_video_info response (see the first post). Note that equal sign will be added automatically between the parameters when you use Job.Download2.

 

[Leni Berry]

ok my mistake... i'll try what response i get for http://www.youtube.com/get_video_info?&video_id=cgxWP4Wu77s

 

[Leni Berry]

with this code :

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    'https://www.youtube.com/watch?v=cgxWP4Wu77s <--- for watching video
    'http://www.youtube.com/get_video_info?&video_id=cgxWP4Wu77s <--- for getting video_info file
    Dim j As HttpJob
    Dim videoid As String="cgxWP4Wu77s"
   
    j.Initialize("youtube", Me)
    j.Download2("http://www.youtube.com/get_video_info",Array As String("video_id",videoid))
   
End Sub

Sub JobDone(job As HttpJob)
    Log(job)
    Log(job.GetString)
    File.WriteString(File.DirRootExternal,"get_video_info_job.txt",job.GetString)
    job.Release
End Sub

i can get "get_video_info_job.txt" file for manually open and check "dashmpd=". but i can't get that string pattern on the file.. even in "get_video_info.txt" file that i get manually from http://www.youtube.com/get_video_info?&video_id=cgxWP4Wu77s via browser....

It seems like Google has changed the response format. There are several urls in the response. The once I tried didn't work.

Is there a way to play youtube with this player?

Read the thread first.
Basically no. Seems you need to find the right url to the stream....

 

[analizer3816]

a simple way is connect saveitoffline api https://www.saveitoffline.com/api/
get video url from json or xml then play with exoplayer

 

[G-ShadoW]

more easy way to find direct youtube link is to use VLC
youtube direct stream works ok

1. Find a video on YouTube and copy the URL from the address bar.
2. In VLC, head to Media > Open Network Stream.
3. Paste the YouTube link in the box and click Play.
4. Under Tools, click Codec Information.
5. In the box that says Location, right-click the block of text and click Select All. Copy this text to your clipboard.
   
   sources.Add(player1.CreateUriSource("youtube link")
