如何使用除Youtube之外的其他来源，从我的应用程序中获取完整的mp4网址来播放视频中的实际位置。 gdata / youtube API已被弃用，因此我遇到了麻烦。任何帮助将不胜感激。感谢。

我制作了一个非常简单的API：https://gist.github.com/el3zahaby/9e60f1ae3168c38cc0f0054c15cd6a83
例如： YouTube视频链接：https://www.youtube.com/watch?v= YGCLs9Bt_KY
现在获取直接链接
你需要打电话给api，就像这样：
https://script-url.com/?url=https://www.youtube.com/watch?v=YGCLs9Bt_KY

对于本地到Java / Android这里我是如何实现这一点的，归功于@ abdo-el-zahaby我将他的php脚本转换为〜等效的java代码它使用okhttp客户端获取网址
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();
}
}
这是我用来下载和存储在SD卡/内存中的代码
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();

抱歉先生，你不能用youtube api v3做到这一点。你必须使用不是api的youtube网址，但在这里你可以获得与此相关的所有视频。 看到 http://www.youtube.com/get_video_info?&video_id=＆＃39 ;. $添加my_id＆＃39;＆安培; ASV = 3及EL = detailpage＆安培; HL = EN_US
或者你可以做所有视频下载链接，即使它是私人的或不允许你的国家 第1步：转到youtube视频链接https://www.youtube.com/watch?v=9mdJV5-eias
的任意网页第二：查看该页面的来源
第3行：188或187行，您可以在其中找到源代码Javascript代码，其中还可以使用mp4格式的视频位置。
你可以通过simplehtmldom和一些php函数来做第二个Idea。并且第一个可以通过使用curl来获得这很容易但有点困难的方式由PHP。谢谢你希望这会对你有所帮助。

我不知道它是如何运作的，但请查看https://podsync.net/。
当您输入youtube播放列表链接时，它会产生一些魔力并生成一个mp4链接供播客捕捉器使用。检查返回的xml文件，您会看到播放列表中每个视频的这样的行：
<enclosure url="http://podsync.net/download/[random-letters]/[video-id].mp4" length="x" type="video/mp4"></enclosure>
根据我的经验，无论您使用什么视频ID，该网址都有效。
