Don't generate download lnk about android-youtubeextractor

[HaarigerHarald]

I can't reproduce it. Can you enable the Logging flag at: https://github.com/HaarigerHarald/android-youtubeExtractor/blob/master/youtubeExtractor/src/main/java/at/huber/youtubeExtractor/YouTubeUriExtractor.java#L35 and post the logs.

[maniek1310]

To change that I have to use the source code? Can I directly from your repository?

[HaarigerHarald]

I assume you are using android studio with gradle. Just copy the youtubeExtractor directory from the repo sources into your project root directory and replace the original dependency with:

compile project(':youtubeExtractor')

After that you can change the logging flag.

[maniek1310]

@HaarigerHarald

add directory from the repo sources into "MyProject\app\src"
add line in settings.gradle include ':youtubeExtractor'
add line in build.gradle (module: app) compile project(":youtubeExtractor")

Error:Configuration with name 'default' not found.

[HaarigerHarald]

I think it should be in the "MyProject" root directory. I think the error means that it can't find the build.gradle file of the library.

Alternatively you can clone the repo, enable the logging flag and run the tests. If there is something wrong, one of them should fail.

[maniek1310]

Ok add directory. I don't log visible download lnk

generate_lnk = (Button)view.findViewById(R.id.generate_yt);
        generate_lnk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //String youtubeLnk = lnk_yt.getText().toString();

                //String youtubeLnk = "https://www.youtube.com/watch?v=qy54tU4KTs0";
                String youtubeLnk = "https://www.youtube.com/watch?v=yRCznT1dEk8";

                Log.d("TTTAG", "ASDDD + " + youtubeLnk);

                YouTubeUriExtractor ytEx = new YouTubeUriExtractor(null) {
                    @Override
                    public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
                        if (ytFiles != null) {
                            int itag = 22;
                            String downloadUrl = ytFiles.get(itag).getUrl();

                            Log.d("YTasdasd", "down_yt = " + downloadUrl);
                        }
                    }
                };

                ytEx.execute(youtubeLnk);
            }
        });

[HaarigerHarald]

Interessting, this seems to be a problem with the javascript library or the webview on your device, since everything up to that point works fine. Did you run it on your phone/tablet or within the emulator?

And are there any other logs regarding the webview visible?

[maniek1310]

I run on phone (Sony Xperia Z3 Android 6). Other logs don't view webview

I've added to your code showing download url :
`

if (curJsFileName != null) {
mat = patEncSig.matcher(stream);
if (mat.find()) {
encSignatures.append(itag, mat.group(1));
}
}
mat = patUrl.matcher(encStream);
String url = null;
if (mat.find()) {
url = mat.group(1);

        if (url != null) {
            Meta meta = META_MAP.get(itag);
            String finalUrl = URLDecoder.decode(url, "UTF-8");
            Log.d("Itag url : ", finalUrl);
            YtFile newVideo = new YtFile(meta, finalUrl);
            ytFiles.put(itag, newVideo);
        }`

Log url lnk is not signatures example https://www.youtube.com/watch?v=pbOw-Hs6LSM

I found the cause of this error. When at get_video_info the parameter use_cipher_signature = true you don't download the video.

[HaarigerHarald]

Signature enciphered videos basically contain a signature that has to be "scrambled up" to produce a working link. The scramble up functions are defined in the player JavaScript file. So to produce a working link we need to run this javascript code. The logs suggest that the JavaScript library which uses the webview fails to run correctly. I suspect there is something wrong with the webview of your device. Can you try running it within an emulator, if that works we would at least know that it's device specific.

[maniek1310]

All my devices problems is the same.

But when I installed the application "advancedDownloader" on your phone, it all works properly.

[HaarigerHarald]

Are you using proguard?

[maniek1310]

@HaarigerHarald
No, but I also tried to use the file "proguard.cfg" in your application AdvacedDownlaoder and still the same.

[sunilsunny565]

I just tested the youtube link you have given.And it's working just fine .This is the download link https://r1---sn-h557snlz.googlevideo.com/videoplayback?ms=au&gcr=in&ip=117.247.187.194&mt=1474523950&mv=m&source=youtube&initcwndbps=157500&id=o-AAROYF009wSaaqiuGoZpftl06yH44lms1VkydFDNgFek&mm=31&mn=sn-h557snlz&nh=IgpwcjAyLm1hYTAzKg03Mi4xNC4yMTEuMTEz&expire=1474546026&sparams=dur%2Cei%2Cgcr%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cnh%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cupn%2Cexpire&mime=video%2Fmp4&key=yt6&dur=204.149&lmt=1474108027869603&ratebypass=yes&itag=22&requiressl=yes&upn=VkH7U0ozDM0&ipbits=0&ei=CnXjV8PPMsf8oAPqmoiICA&pl=24&signature=7FD5DE99A25A43D2A7C78CCED6EEE247660D35BA.7EA2F83E502406512934DB1408669ABFDA4C9BCD .

Just add this line.it requires an additional parsing.
ytEx.setParseDashManifest(true);

[maniek1310]

@sunilsunny565
Don't help. You can send me your working on a project where you checked?

@sunilsunny565 Your download url can not open.

[maniek1310]

I'm sorry for the trouble. Already it works was enough to pass Activity class YouTubeUrlExtractor

replace
YouTubeUriExtractor ytEx = new YouTubeUriExtractor(null)
on
YouTubeUriExtractor ytEx = new YouTubeUriExtractor(activity)

I saw a step-by-step how to operate your library and noticed that checks every pass and how it will be null activity don't run js-evaluator.
