How to use Youtube Live Streaming API ??

I want to make a WPF application that gets the video from my ip camera and sends it to my youtube channel live. I look around all of the websites but there's no example how can i live stream a video to Youtube with c#. There are examples in google's website
but they were written with PHP, Java and Phyton but I don't know this programming languages so i couldn't use the API.
I tried to write a little bit but it didn't work. Here's my code that i wrote looking through the Java example.
string devkey = "AIzaSyCbxm6g9orAw9PF3MkzTb_0PGbpD3Xo1Qg";
string username = "MyYoutubeChannelEmailAdress";
string password = "MyPassword";
YouTubeRequestSettings youtubereqsetting = new YouTubeRequestSettings("API Project", devkey, username, password);
YouTubeRequest youtubereq = new YouTubeRequest(youtubereqsetting);
LiveBroadcastSnippet broadcastSnippet = new LiveBroadcastSnippet();
broadcastSnippet.Title = "Test Live Stream";
broadcastSnippet.ScheduledStartTime = new DateTime(2015, 3, 12, 19, 00, 00);
broadcastSnippet.ScheduledEndTime = new DateTime(2015, 3, 12, 20, 00, 00);
LiveBroadcastStatus status = new LiveBroadcastStatus();
status.PrivacyStatus = "Private";
LiveBroadcast broadcast = new LiveBroadcast();
broadcast.Kind = "youtube#liveBroadcast";
broadcast.Snippet = broadcastSnippet;
broadcast.Status = status;
Google.Apis.YouTube.v3.LiveBroadcastsResource.InsertRequest liveBroadcastInsert = new Google.Apis.YouTube.v3.LiveBroadcastsResource.InsertRequest(service, broadcast, "");
LiveBroadcast returnLiveBroadcast = liveBroadcastInsert.Execute();

Trying to find lowest latency setting for FMS 3.0 live streaming app

Hi,
I work for a technology company in the agricultural industry,
and we recently bought Adobe FMS 3.0 for live streaming of an
online auction application. Initially the tests were ok, but the
stream latency is becoming a real issue. It starts at around 1s
delay, which is barely acceptable, but an hour into the sale it
stretches to 2-3s, and more. This is becoming a real deal breaker
for the Flash solution that looked very promising at the beginning.
We need to find the absolute lowest latency setting for the
live streaming application supplied with FMS3.0.
Low latency (1s max) and stable latency has highest priority,
more important than picture quality or uninterrupted streaming.
How can we achieve this? Are there any settings where I can
tweak the stream latency?
I am not a Flash expert, but I can find and modify the
configuration files on the FMS Windows 2003 server.
Any help would be immensely appreciated.

On server side:
FMS installs itself with default configurations optimized for
Max CPU efficiency. Reducing/shutting-off FMS publisher queues
using Application.xml config should help in removing the delay that
you experienced.
<Application>
<StreamManager>
<Live>
<Queue enabled="true">
</Queue>
</Live>
</StreamManager>
</Application>
Changing default setting to <Queue enabled="false">
disables live publisher queues & aggregate messages ad
therefore "the delay". (the delay should be reduced to <100 ms
for a perfect kind of network or LAN)
--> On client side: Do NOT use NetStream.setBufferTime API
at all ! i.e. do not set any buffer on client side.; Flash player
(upto 10, the current version) would try its best to keep the
buffer around 0.1 seconds, which is the default value.
OmicronPersei8,
Which publisher are you using to publish the live stream?
Sometimes , it is possible that a some fault at stream publisher
may make buffer at flash player grow.
I hope this would help !

Nokia E6 live streaming not working

its only one month i've updated my mobibe due to hanging problem and now it s giving me another pain for not playing any live streaming video like online tv or you tube streaming... Also still have the hanging problem.
Help me out if anybody has a solution.

Hi Lance09
Sorry to hear that you are having troubles.
Did you purchase a free trial through the AFL Live Pass Online or did you purchase through IN APP subscription?
Can you please try these troubleshooting steps:
If using your fixed line connection (ADSL, CABLE or NBN), please powercycle your modem and computer: Unplug from power > Leave off for 10 mins > then Plug back in and re start. This will often force a line update through to your modem advising the signal is restored.
Can you then please try clearing your Cache, Cookies and Browser history. To clear these please try the steps below:
From the home screen, tap the Settings button. On the Settings screen, scroll down and tap the Safari button. Under the 'Privacy' section of the Safari screen, tap the button labeled Clear Cookies and Data. On the confirmation screen, tap Clear Cookies and Data.
If still no luck, please try uninstalling and re installing the app from the app store.
Let us know how you go.

Live Streaming video and Flex2(3?) + Flash Media Server?

I've seen alot of topic on how to create video sites for
clips, etc. with Flex and Flash Media Server, but how about live
streaming video, like a concert or a seminar. I can't find any
information on this at all, could anyone point me in the right
direction?

What you need is grab video/sound form camera/mic, publish it
on FMS and let the other clients play it. In a few steps:
// get camera and mic
var cam:Camera = Camera.getCamera(); // get default camera
var mic:Microphone = Microphone.getMicrophone(); // get
default mic
// if you have VideoDisplay, for monitoring
videoDisplay.attachCamera(cam);
// create new RTMP connection to FMS/your app
var nc:NetConnection = new NetConnection();
// new stream should be create *after* nc has connected, not
before
// so this is executed after the below nc.connect() succeeds
nc.attachEventListener(Event.CONNECT, function(){
var ns:NetStream = new NetStream();
ns.attachCamera(cam);
ns.attachMicrophone(mic);
ns.publish("streamname", "live"); // or "record" if you want
to live+rec
// connect to default instance of app 'appname' on your FMS
nc.connect("rtmp://fms.ip.address/appname");
If you're using Flex2 and FMS2 (the latest FMS is 3), you
might need to
cuange the connection encoding to AMF0 (which is what FMS2
uses) in order for this to work.
Hope this helps; I've written it from my head so it probably
has mistakes, but it's the general workflow; the docs in the
language reference for specific functions mentioned here will also
help.

Live stream monetization?

Hi
I have live stream application how i can monitor when that stream input and corresponding streamouts are active and how i can map between stream input ID and streamoutput ID???

You should be using the access logs that FMS produces for monetization of your streams. In particular you want to pair the events that happen play/stop and in the stop event the corresponding sc-bytes or sc-stream-bytes. These values dictate how many bytes of a stream that a player of your application will consume. You can identify them uniquely from the client ID attached automatically to the event.

Debugging live streaming ingest protocol

Hi everyone,
I posted a separate question last week about live streaming protocols. I had been searching for documentation on fmp4 live streaming ingestion and found nothing, but afterward I found the Smooth Streaming protocol specification (MS-SSTR-- the forum won't
let me link to it directly), which seems to apply to my use case. Now I've spent a few days trying to make it work and so far haven't been able to do so.
I'm not looking for a canned solution; I'm looking for resources to help me debug the problem.
According to the specification, I should be able to make a long-lived, chunked http POST request to my ingest endpoint, sending the fragmented mp4 data as the request body. I've tried to implement this without success-- I open the request stream and
write 1000 byte chunks at a time, but the connection is reset after only one or two chunks. I can't tell if the problem is the data or the chunk size or something else.
And if I mimic Expression Encoder 4, which seems to diverge from the spec and not send its data chunked at all, the connection isn't reset no matter how much data I send, but the video never makes it to the preview stream on the Azure portal.
So the question is, how can I debug this? Is there any error log or diagnostic output I can access? Each time I try something new, it doesn't work, but I have no way of knowing whether I am getting closer to or further from a working solution. I'm a bit
lost here, so help would be greatly appreciated.

Hi Jason, and thanks for getting back to me.
The IP security thing is a good thought, but I think I have that part taken care of already. I saw the option to restrict ingest to the IP I used to configure the channel from in the Portal, and I made sure to set it to Off. Also, I can stream successfully
from Expression, which would have the same source IP.
As for why I want to use Smooth Streaming, basically there are two reasons. First, it seems like the simpler protocol conceptually. I'm already generating fragmented mp4 files (though I think they might be packaged wrong; I can't really tell which part is
causing problems), and it seems simple enough that I could implement it without turning to a third-party library (the part that's feeding the stream is written in C#, though I'd be willing to rewrite in C++ if necessary, and there's no RTMP client
that seems trustworthy-- FluorineFX, for instance, seems to have ceased development years ago now).
Second, while reading the RTMP spec, I realized that even if I had such a library it isn't clear how I would need to use it with Azure. It allows creating objects or invoking methods on the server, but I couldn't find any guide to which objects and methods
might be supported. And the spec also doesn't define specifically what video format, codec options, or packaging method I need to use; essentially I would seem to have all the same problems I'm having with Smooth, only with the added difficulty of needing
a third-party library to implement the spec properly.
I guess the main problem is that I don't really know how close or far I am from success. Like I said, I think I am doing something wrong in how the video is encoded, but for all I know I'm being dropped because I'm feeding the data too quickly
or slowly. (I can't find any documentation on how much data Azure can buffer or how it handles underruns when the video to be streamed live is generated on the fly and not tied to strictly realtime output). If there's more documentation on specifically how
Azure uses or expects data from these protocols, it'd be very helpful.

Live stream not live- plays like VOD

Hi All,
I'm not sure if this belongs in the AS3 forum or the streaming forum, but here it is.
I wrote a pair CS3/AS3 players to send and receive a live video stream (webcam) from a browser. The first is called broadcaster. It makes a NetConnection to my server, publishes a stream and attaches the camera and microphone. This works fine. The stream is live.
The second is originally called receiver. Using an instance of flash.media.video on the stage it also makes a NetConnectin, attaches a stream and calls play. This also works, BUT the receiver stream is not live. It starts playing at time=0 like a VOD.
--- broadcaster.swf ---
var connection:NetConnection = new NetConnection()
connection.connect(connect_url); // my server/application/instance
var stream = new NetStream(connection);
stream.publish("mass", "live"); // live means stream live without recording on the server
stream.attachCamera(Camera.getCamera());
stream.attachAudio( Microphone.getMicrophone() );
--- receiver.swf---
connection.connect(connect_url);
var stream = new NetStream(connection);
video1.attachNetStream(stream); // video1 is on the stage (flash.media.video not FLVPlayback)
stream.play("mass", -1, -1, true); // -1 means play live stream only, -1 means start at 'wherever the live stream is'
How can the receiver not obey the -1, -1 parameters especially if the broadcaster is not recording on the server. How can i see the beginning of the stream!
I believe I read that the flash plugin 9.0+ uses the on2 codec, and I also saw some discussion about on2 not able to stream live -- or not live from the browser plugin, only the flash media encoder.
Can anybody tell me what is going on?
Thanks
Ted

I tried streaming with the Adobe Flash Media Live Encoder3 instead of my Broadcater.swf. This connects fine and pushes h.264 no problem.
But the reciever is still seeng VOD not Live video.
Is there something wrong with my receiver?

HTTP Live streaming test in Flash Player, HTML5 player, iphone, android and other smart phones.

Hi,
Can anyone please tell me how can I play http live streaming from FMLE 3.2 to Flash player, iphone, ipdad, HTML5 player, Android and other devices?
I have tried my best to play live streaming usine FMLE 3.2 with help of "http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd609-52e437a812a3725df a0-8000.html" but not able to play video using HTTP.
When I tried to play url- "http://localhost/hds-live/livepkgr/_definst_/liveevent/livestream.f4m" even in in Strobe Media Player it was showing "Buffering" that's it. But I can play same RTMP URL in Flash AS3 using the netstream very fine.
Now I want to test the livepkgr content via HTTP to Flash Player, HTML5 Player (on Web browser and smartphones), iphone and other devices.
Thanks
Best regards,
Sunil Kumar

Hi Sunil,
It's difficult to debug an issue when you don't have access to the machine and you can't see what's happening, so I request you to please have a little patience.
For playback just check the following steps and make sure if you have followed them :
1) Delete the streams folder and any .stream file in the livepkgr
2) Restart FMS
3) Make sure you have a crossdomain.xml under root_install/webroot
4) Publish a stream from FMLE as 'livestream?adbe-live-event=liveevent'
5) Use this player to playback the stream : http://osmf.org/dev/2.0gm/StrobeMediaPlayback.html?src=http://<your-ip>/hds-live/livepkgr/_definst_/liveevent/livestream.f4m
If there is no playback, here are some checks you can do :
1) Request for the http://<your-ip>/hds-live/livepkgr/_definst_/liveevent/livestream.f4m in your browser. You should receive an xml that looks something like this :
<?xml version="1.0" encoding="UTF-8" ?>
     <manifest xmlns="http://ns.adobe.com/f4m/1.0">
          <id>livepkgr/events/_definst_/liveevent</id>
                  <mimeType />
          <streamType>live</streamType>
          <duration>0</duration>
          <bootstrapInfo profile="named" url="../../../streams/livepkgr/events/_definst_/liveevent/livestream.bootstrap" id="bootstrap7158" />
          <media streamId="livestream" url="../../../streams/livepkgr/events/_definst_/liveevent/livestream" bootstrapInfoId="bootstrap7158">
                      <metadata>AgAKb25NZXRhRGF0YQgAAAAAAAhkdXJhdGlvbgBAJUUeuFHrhQAFd2lkdGgAQHQAAAAAAA=</m etadata>
            </media>
</manifest>
2) Check the access log under Apache to see if the .f4m, .bootstrap and Frag files have been requested and delivered. If a particular entry has a status code of 200 then the file has been served by FMS. You can confirm the same on the client side using a software like fiddler.
Coming to the player issue, a playback of *f4v via the vod directive is a progressive download, whereas playback of an *f4m file via hds-vod is HTTP streaming.
I have personally used Spark VideoPlayer and hence suggested the same.
You need to add a component like :
<s:VideoPlayer width="100%" height="30%" chromeColor="#CCCCCC" color="#000000"
                 fontSize="12"
                 source="http://<your-ip>/hds-live/livepkgr/_definst_/liveevent/livestream.f4m"
                    symbolColor="#000000"/>
Let me know if any of these suggestions help.
Thanks,
Apurva

Publish Live stream to FMS on RTMPE protocol

Hi,
I am trying to publish Live Stream to FMS using FMLE or third party encoders.
Is it possible to have RTMPE or RTMPTE protocol used between encoder and FMS?
Very urgent.
thanks,
Pooja Jain

FMLE can only publish via rtmp or rtmpt.

Clearing application buffer after a live stream ends

Hi there, I'm sure this has been asked and answered a million times, but searching for "application" "buffer" "cache" "live" and "hls" isn't giving me any answers, so let's get to it...
After I end a live stream (which I do using FMLE 3.2 and FMS 4.5) and I then start a new live stream with the same application name, the HLS stream just loops the last 30 seconds of the old stream. To prevent this, after I end a stream, I have to go to applications\livepkg\streams\_definst_\ and delete the buffered data there. Only then can I start a new stream with the same name as the old stream. Now... that can't be normal, can it? Is there a switch somewhere I can set to tell FMS to cut it out and stop buffering old streams?
Thanks,
Raul

You can use "record" mode rather than default mode of "append". You just need to publish using streamname - livestream%i?adbe-live-event=liveevent&adbe-record-mode=record.
Though "append" should also work - can you let me know what do you see in FMS core logs / application logs. Also are you changing encoding settings when you republish/restart?

No audio on some App like tennistv the have live stream video, I used to hear the audio, they told me is an iPad issue, also trayed RolandGarros App no audio

I have several Tennis App like TENNISTV, US OPEN, ROLANDGARROS and last month I noticed that I have no sound on the video (this is live streaming) games if I do log in on my PC there is video and audio playing, I did contact them, the 1st suggestion was to delete the app and reinstalled, I did not worked still no sound at all, they told me to contact Apple

Have you got notifications muted ? Only notifications (including games) get muted, so the Music/iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

P2P-based live streaming protocol

In a P2P-based live streaming system , a video stream is diveded into segments of uniform length. Each segment contrains 1-second video data.Every peer in the overlay owns a buffer to save segments temporarily.Then, what kind of protocol is appropriate to transmite 1-secong vido data?UDP or RTP?
If RTP was used ,what kind of process should be take to get the video data which be send to buffer but not to play at once?

So you know, there are no Macromedia guys... there are only
Adobe guys, and I wouldn't expect answers from any of them here.
This is a user to user forum.
I don't work with mobile devices much, but Flash Lite
supports the Flash 7 standard , so I would imagine the
netconnection and video classes are in there. If that's the case,
then you should be able to deliver Sorenson Spark encoded flv files
(the flash 6/7 standard).
