问题
How do I get the full mp4 url to play the video from it's actual location in my application using some other source except Youtube. The gdata/youtube API has been deprecated so I am having trouble. Any help will be appreciated. Thanks.

i made a very simple API : https://gist.github.com/el3zahaby/9e60f1ae3168c38cc0f0054c15cd6a83
As Example: YouTube Video Link: https://www.youtube.com/watch?v=YGCLs9Bt_KY
now to get the Direct link
you need to call the api , like this :
https://script-url.com/?url=https://www.youtube.com/watch?v=YGCLs9Bt_KY
returns:

Sorry sir, You cannot do this with youtube api v3. you have to use a url of youtube which is not an api, but here you can get all the videos related to this. See http://www.youtube.com/get_video_info?&video_id='. $my_id.'&asv=3&el=detailpage&hl=en_US
Or you can do to get all the videos download link even it is private or not allow for your country 1st: Go to any webpage of youtube videos link https://www.youtube.com/watch?v=9mdJV5-eias
2nd : view source of that page
3rd : 188 or 187 line, where you find source Javascript codes where location of the videos with mp4 format is also available.
You can do the second Idea by simplehtmldom and some php functions. and the first one can get by using curl which is easy but in little bit hard way by php. Thank you hope this will help you.

For Local to Java/Android here is how i achieved this, credit goes to @abdo-el-zahaby i converted his php script to ~equivalent java code it uses okhttp client to get urls
final String videoInfoUrl = "http://www.youtube.com/get_video_info?video_id=some_video_id&el=embedded&ps=default&eurl=&gl=US&hl=en";
Request request = new Request.Builder()
.cacheControl(CacheControl.FORCE_NETWORK)
.url(videoInfoUrl)
.build();
final Response response = okHttpClient.newCall(request).execute();
InputStream inputStream = response.body().byteStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
final StringBuilder contentBuilder = new StringBuilder();
while ((line = bufferedReader.readLine()) != null) {
contentBuilder.append(line);
}
final String streamKey = "url_encoded_fmt_stream_map";
final Map<String, String> map = new HashMap<>();
final String content = contentBuilder.toString();
String[] ampSplit = content.split("&");
for (String s : ampSplit) {
printDivider();
final String[] equalsPlit = s.split("=");
if (equalsPlit.length >= 2) {
String key;
String value;
key = equalsPlit[0];
value = equalsPlit[1];
map.put(key, value);
}
printDivider();
}
int count = 0;
if (map.containsKey(streamKey)) {
String[] streams = map.get(streamKey).split(",");
for (String stream : streams) {
String[] streamSplit = stream.split("&");
for (String s : streamSplit) {
printDivider();
final String urlDecoded = URLDecoder.decode(s, "UTF-8");
String[] details = urlDecoded.split(",");
for (String detail : details) {
System.out.println("Detail " + URLDecoder.decode(detail, "UTF-8"));
final String urlContent= URLDecoder.decode(detail, "UTF-8");
final String url = urlContent.substring(urlContent.indexOf("http"), urlContent.indexOf(";"));
mp4Url.put(Integer.toString(count++), url);
}
}
printDivider();
}
}
This is the code i am using to download and store in sdcard/internal memory
Request request = new Request.Builder()
.cacheControl(CacheControl.FORCE_NETWORK)
.url(url)
.build();
final Response response = okHttpClient.newCall(request).execute();
InputStream inputStream = response.body().byteStream();
final File newFile = new File(location);
boolean created = newFile.createNewFile();
System.out.println(location + " new file created: " + created);
byte[] buff = new byte[4096];
long downloaded = 0;
long target = response.body().contentLength();
System.out.println("File size is: " + Long.toString(target));
OutputStream outStream = new FileOutputStream(newFile);
while (true) {
int read = inputStream.read(buff);
if (read == -1) {
break;
}
outStream.write(buff, 0, read);
//write buff
downloaded += read;
}
System.out.println("Target: " + target +", Downloaded: " + downloaded);
outStream.flush();

I don't know how it works, but check out https://podsync.net/.
When you input a youtube playlist link, it does some magic and generates an mp4 link to be used by podcast catchers. Examine the returned xml file and you'll see lines like this for each video in the playlist:
<enclosure url="http://podsync.net/download/[random-letters]/[video-id].mp4" length="x" type="video/mp4"></enclosure>
In my experience, that URL works no matter what video-id you use.
