LiveStream video is extracted without audio

[JmyW]

Hi Since yesterday, the Live Stream video became failed. The extracted URLs in ytFiles are not including both Video and Audio. I check each ytFile through getAudioBitrate, they all are -1, means no sound. I can find one with 128kbps but its video height is -1, means no video. Does anyone know the reason? Could Harald or anyone help to analyse it? Thanks in advance.

@kaiv2000 Have you gotten the solution?

[kaiv2000]

unfortunatelly not yet

[jishantmed]

@kaiv2000 you are using "hlsvp" to get a match live tv or not. this has been changed "hlsManifestUrl" please check .Hope it will help you

Do you guys got the solution for it?

[JmyW]

No 😢 I have even dropped down my app in store for a while. But I'm hoping someone can help me to solve it and resume my app in store.

Thank you. Converting the pattern from "hlsvp" to "hlsManifestUrl", work. Being able to stream youtube live streams with audio.

@anirudha-banerjee Could you share more how to "convert" the pattern from hlsvp to hsManifestUrl? Where should be modified in code?

[anirudha-banerjee]

@JmyW You need to make the change in YouTubeExtractor class in youtubeExtractor module. Inside the class you will find, all the patterns that this project is using in order to extract video data. There search for "hlsvp" pattern and replace with "hlsManifestUrl(.+?)(&|\z)". If this does not work, please replace with "hlsManifestUrl%22%3A%22(.+?)(&|\z)". "%22%3A%22" means ":".

[JmyW]

Thanks! Yes, I'm using the youtubExtractor locally. Then I followed your string "hlsManifestUrl%22%3A%22(.+?)(&|\z)". I tested and found a few of live video can be played now but most of them are still failed. :-(
Can you share some YouTube URLs you succeeded for me to do further analysis?

I too found that the links which were playing on my phone(android 8), were not playing on my tab(android 5). While debugging saw that, after getting hls data using "hlsManifestUrl%22%3A%22(.+?)(&|\\z)" pattern, when i call new BufferedReader(new InputStreamReader(urlConnection.getInputStream())), the code gives "FileNotFound" Exception. Now, this was happening only on my tab. Whereas, on phone any youtube live link i parse, it starts playing. So tried the following method, for the code to work on both the type of device and on all types of youtube live link(Have checked a couple of youtube live links, have shared the links below).

After you have extracted hls data using the above mentioned pattern, you will have to extract the exact url, ending in ".m3u8", from the above mentioned hls sparse meta data. Use "(.*?)^https(.*?)(?=\")" pattern to extract hls link ending in ".m3u8". After extracting the link, use that link to open connection and then get the stream.

So the code now should look like this: Also i have replaced finally with catch.

private static final Pattern patHlsManifestUrl = Pattern.compile("(.*?)^https(.*?)(?=\")");
private static final Pattern patHlsvp = Pattern.compile("hlsManifestUrl%22%3A%22(.+?)(&|\\z)");

if(videoMeta.isLiveStream()){
            mat = patHlsvp.matcher(streamMap);
            if(mat.find()) {
                String hlsvp = URLDecoder.decode(mat.group(1), "UTF-8");
                SparseArray<YtFile> ytFiles = new SparseArray<>();

                mat = patHlsManifestUrl.matcher(hlsvp);
                if (mat.find()){
                    getUrl = new URL(URLDecoder.decode(mat.group(), "UTF-8"));
                    urlConnection = (HttpURLConnection) getUrl.openConnection();
                    urlConnection.setRequestProperty("User-Agent", USER_AGENT);
                    urlConnection.connect();
                    try {
                        reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
                        String line;
                        while ((line = reader.readLine()) != null) {
                            if(line.startsWith("https://") || line.startsWith("http://")){
                                mat = patHlsItag.matcher(line);
                                if(mat.find()){
                                    int itag = Integer.parseInt(mat.group(1));
                                    YtFile newFile = new YtFile(FORMAT_MAP.get(itag), line);
                                    ytFiles.put(itag, newFile);
                                }
                            }
                        }
                    }
                    catch (FileNotFoundException ex){
                        Log.e(LOG_TAG, "Problem while extracting live url", ex);
                        if (reader != null)
                            reader.close();
                        urlConnection.disconnect();
                    }
                    if (reader != null)
                        reader.close();
                    urlConnection.disconnect();

                    if (ytFiles.size() == 0) {
                        if (LOGGING)
                            Log.d(LOG_TAG, streamMap);
                        return null;
                    }
                    return ytFiles;
                }
                return null;
            }
            return null;
        }

@anirudha-banerjee Thank you so much for your sharing. Yes, it's great! Your solution fixes it, the Live video is now able to be played. Thank you!

@anirudha-banerjee what are streamMap and patHlsItag or those are available only in the previous versions/code? I'm trying to add this code and it shows me an error Cannot resolve symbol... while using both of the variables.
