Stopping FMLE programatically?
We've just started using Flash Media Live Encoder with an Osprey capture card on a Windows 2003 server.
The challenge I'm having it trying to figure out how to STOP the stream after a predetermined time.
We can start the product using the Windows scheduler, and that works okay, but I can't figure out how to get it to stop automatically.
The issue is, we're a PBS station, and want to stream only certain programs (live political debates, etc.) So, we need a way to start the stream at, say, 7:00 PM. and stop it at 8:30 PM.
I actually considered scheduling SHUTDOWN.EXE to force a reboot of the server, but that seems a bit extreme.
The stream is being sent to a CDN, and then presented by JWplayer on our website.
Any suggestions?
Worked brilliantly -- thanks!
(Now I just have to figure out a way to get the JWplayer to replace the stopped image from the live stream with a "that's all, folks!" jpg image.)

Switching audio sources without stopping FMLE
We use several Osprey cards, and wish to change from one audio/video source to another audio/video source without stopping FMLE.
We can do the video switching from one Osprey input to the other using wirecast or vidblaster software video mixers, but are at a loss how to switch the sudio from one osprey input to another without stopping FME and selecting the other audio inpout from the drop-down list. We do not know of any audio mixer that FMLE recognises with which we can accomplish changing one audio source to another withour stopping FMLE.
Any information in this regard much appreciated,
Thank youto my knowledge, there is no software mixer with 0 lag because its software. Hardware allows for no lag because theres nothing reading the info, encoding etc. Software reads the audio data, usually it chunks, this is why it creates lag. i did some testing using a usb mic and listening for the amount of time between me making the sound and it actually coming out. Its just barely noticeable to annoy the person talking if he or she were to be listening to it through headphones or speakers, but i would estimate about 1/8 of a second. Though if you want to be able to remotely control a mixer and you have someone working with you with a little technical experience, you could have them rig up a remote control system using remote control airplane actuators to turn the knobs.
also while looking mackie control mixers say they have motorized faders, and since its program controlled, i believe you can actually control the faders using a program, but his would mean getting a new mixer. if you want to look these up, http://www.mackie.com/products/mcupro/ -
Starting and Stopping FMLE from command line yields corrupt .flv files
I am using FMLE to record and live stream TV content. In order to this I am remotely calling FMLEcmd in order to start and stop encoding processes. The problem that I am running in to is that the .flv files generated are corrupt. The odd thing is that if I use the exact same profile XML from the GUI, then the encoding process works just fine and results appear as intended.
Here is the way my workflow works:
I start the process by calling
FMLEcmd /p C:\lighttpd\htdocs\xml\default.xml /l C:\lighttpd\htdocs\logs\log.txt
then at the conclusion of the recording I call
FMLEcmd /s "C:\lighttpd\htdocs\files\default.flv"
When I attempt to open the files using FFmpeg I get a codec error saying that no codecs were detected. When I attempt to open the files in VLC I get a error saying that the media types are "Undf". When I attempt to open or modify the files with flvtool2 I get an end-of-file error. My guess is that my stop command is incorrect and somehow abruptly stopping the stream, but I don't know another way to stop the stream. Do I need to specify a specific stream duration in the XML and make sure to call the stop command *after* the duration has been reached? What would cause this codec corruption when the same profile works properly from the GUI?
Here is the profile I am attempting to use.

AFAIK, after placing stop command, FMLE took some time to write proper EOF in FLV. wait ~10 sec for FMLE to complete file writing process and than play in FLV PLayer.

I know how to programmatically set the start date/time for the timer to start executing...
But how does one set the end time so that the TimerTask would gracefully stop executing..
This is the scenario:
I want to post data to a servlet at a 5 minute interval and I want to do this only from 8 am to 5 pm everyday.
I know that I need 2 TimerTasks. TimerTask1 and TimerTask2
TimerTask1 is to execute scheduleAtFixedRate() every 5 minutes. And TimerTask2 needs to execute every 8 am.
How do I tell TimerTask1 to stop posting data to the servlet when the time reaches 5 pm?
Pls help. Thanks.put it in a tread that spawns at 8:00 am and then the spawned thread can check time every XX minutes. When it's 5pm stop the tread and dispose it appropriately.

Any way to control FMLE publishing?
Is there any way to stop FMLE (3.0.1) from publishing a stream?
I have seen code before where you send "NetStream.Publish.BadName" back to onFCPublish - example:
Client.prototype.FCPublish = function( streamname )
// Reject the stream
this.call("onFCPublish", null, {code:"NetStream.Publish.BadName", description:streamname});
The encoding log on my FMLE reads:
Mon Mar 15 2010 14:33:09 : Primary - Network Command: onFCPublish
Mon Mar 15 2010 14:33:09 : Primary - Stream[testStream] Status: Success
Mon Mar 15 2010 14:33:10 : Primary - Stream[testStream] Status: NetStream.Publish.Start
Mon Mar 15 2010 14:33:10 : Session Started
Mon Mar 15 2010 14:33:12 : Video Encoding Started
Mon Mar 15 2010 14:33:12 : Audio Encoding Started
I can see where onFCPublish was called, but the stream still published.
Any thoughts?What is your use case at first place? What you are seeing is expected behaviour. So you can let me know your use case and then we can go ahead and try to find solution for it.

Does FMLE support authenticating with FMS?
When user publishes the live stream to FMS,
he should provide user/password to authenticate.
Is that viable with FMLE?Thanks,
my other part of the problem is:
is it possible to start/stop FMLE in actionscript for webcast[ing? -
Can I get my Flex app to use FMLE programatically to encode
my live stream. Ideally, I would like to use H.264, but for now, I
will be OK with Sorensen encoder as well. I cannot expect my user
to be running FMLE on their PCs. If that is not possible, do you
know if there is a way to use the Microsft H.264 in conjunction
with my Flex app? Any help is appreciated. Thanks, RameshHi Laurel, how would I use the flash player in my Flex app.
Currently, in my flex app, I use Video class object and I get the
camera using getCamera call, I create a NetConenction and NetStream
and I call publish to stream the video using FMS. My understanding
is that in my process, there is no encoding and I am sending s raw
stream.
If you are saying that flash player can encode H.263, should
I be calling a special video object? Should I be using VideoDisplay
object? Can you please clarify as to how I would use Flash player
to stream out the message? Thanks, Ramesh -
AMS play back stops once 30 ppl are watching
Hello,
I am posting this here and the Adobe Forum service.
I am streaming live/dvr with 5.0.4 using the m1.large ec2 server. I have streamed well with 100+ people watching at the same time for 72 hrs events.
I have 14 live feeds each connected to a different aws cloudfront. All feeds exists on the 1 ec2 adobe server (livepkgr 1-14)
My web code calls to an standard .swf strobe player on my server (that came with AMS,) through cloudfront also.
My streams are viewed on my website through enbed code which ask for .f4m and .m3u8 through amazon cloudfront code to reduce server calls.( as I thought this might help with any bandwidth issues since each cloudfront is suppose to be 27 extra cache servers?) The problem I just ran into this weekend was, with the only difference being the .swf player was on adobe.com
I was only using 1 live feed this time. Then, once 31 people were viewing on 1 cloudfront feed the strobe player would stop on the website.!!?? I would have to stop FMLE live feed and restart each time. Then the feed would come back and again once 30+ viewers were watching, down again. And the feed was being shown on two separate websites. Both sites have unlimited bandwidth in terms of people who can log on to watch.
I am only encoding at 400kbs. on 1 feed, through 1 cloudfront. My ec3 was only at 10% usage.
30 ppl would be only 12 Mbps
Can someone please help. What should be my best setup to get the most out of this size ec2 before have to move up to the larger servers.
Seems as though I should be able to more than 30 people to watch at one time on a m1.large
Thank you greatly.
Extra note: I have used the c1. class ec2's and can get 150 viewers. The ec2 is 8x larger, but will I get this same problem when 240 viewers are watching?You say your sequence settings match the clips. But if they really match, there shouldn't even be an opportunity to render on the timeline.
You are probably using a codec that is not DV - clearly it is not the same as your timeline or you wouldn't need to render.
Thanks everyone for your input, but I'm still at a loss and pulling my hair out. First, let me reiterate that these clips play back perfectly smoothly in iMovie, and in a larger window to boot, without dropping any frames. So I doubt my older G4, or hard-drive data throughput, is to blame.
Let me clarify the problem. When I view clips in the Viewer, I'm not sure that frames are being dropped. Rather, every 2 secs (like clockwork), the clip freezes momentarily, then plays smoothly for another 2 secs, almost as if a cache is being filled up before playing the next 2 sec.
I've double and triple-checked that my settings, and clips, are for DV. The clip icon on the desktop is a little slate with the letters "DV" in the center.
My A/V Settings show the Sequence Preset: DV NTSC 48 kHz
My Sequence Settings are:
Frame size: 720 x 480 NTSC DV (3:2)
Pixel aspect ratio: NTSC-CCIR 601/DV (720x480)
Field dominance: Lower (even)
Editing timebase: 29.97
Compressor: DV/DVC Pro NTSC
Quality: 100% (i.e. Best)
Scan mode: Interlaced
Aspect ratio: 4:3
Audio rate: 48 kHz
Audio depth: 16-bit
Audio config: Default
Lastly, the only 2 strange things I've found is that even though the clips are DV, in the clip properties it says the data rate is 6.9 Mb/sec (I thought DV is 3.2 Mb/sec). Also, the audio says 32 kHz (I thought DV is 48 kHz). Does this mean anything?
Thanks again! -
Why does the /s not work for me in the commandline?
We have a HD webcam pointed at a pooltable in our local poolbar. We use FMLE to stream to Dacast. To finish the project we want to automate the process: only stream between 17.00 and 01.00 hours every day.
It looks like FMLEcmd + batch/cmd files + scheduled tasks can make this possible.
I am diving into FMLEcmd. Starting up works fine. But stopping gives me troubles. I use the command: fmlecmd /s rtmp://live-ams.dacast.com/201346/21653+xxxx
Reply is: "Stop command send to FMLE."
Then i do fmlecmd /s and it says " All running FMLE sessions are: rtmp://live-ams.dacast.com/201346/21653+xxxx".
Questions:
1. What am i doing wrong here?
2. When starting a session through cmd, will it be visible when you open FMLE Gui?
Plan is to make two batchfiles: One to start FMLE streaming on a daily basis at 17.00 hours. And one to stop FMLE streaming at 01.00 in the morning. If somebody already has similar batchfiles ready for me to use, please let me know! If somebody has another solution for the above, also let me know!
Already implemented the reconnect interval and times in the XML file... that was needed...
Maybe stupid question: When i do the command "FMLEcmd", encoding starts, text displays "streaming to server", and i see bitrates moving. Is the only option then to close the command window? Because i see no cursor anymore?
Thanks in advance, any help is appreciated.

ADDON: I just restarted my computer to stop the streaming session. But doing fmlecmd /s still says:

Many thanks for your reply.
It doesn't give me an error message, it simply does not search. I type in my search term and it appears to search the document but then a dialogue box appears which says that my search term has not been found. This even happens when I am looking at a page in which my search term is clearly visible!
I am shutting down now until the morning as I have been working almost 12 hours. -
i need to restart the midlet in my app to apply my new settings ???
@Ran_Cu
Please enlighten us which class has a method repaint (). I was unable to find any such method in the API docs.
@OP: The startApp () method is called by the system whenever a MIDlet (1) starts and (2) resumes from standby. Similarly, pauseApp () is called when a MIDlet is sent to standby.
You cannot restart a stopped MIDlet programatically.

Broadcast Gradually Loses Quality
Copy and pasted from my topic on creativecow.net:
Hello everyone. My name is Danny, a Justin.TV broadcaster who goes by the name iMoogle. I recently bought a new computer along with an intensity pro, and have tested it using Adobe Flash Media Live Encoder (FMLE) to upload the stream to JTV. The video is perfectly fine for the first 7-8 minutes of intense action, but after that, many things start to happen:
- The video bitrate show in FMLE starts jumping from very low to very high bitrates, nowhere near the selected bitrate (700kbps). I've seen it jump from 50kbps to a whopping 2000kbps for unknown reasons. It's not very noticeable in the video, but an inconsistent bitrate can never be good. When it streams perfectly fine, it only jumps between the range of 650 and 750.
- The FPS starts to drop dramatically. From a very very steady 30FPS, then gradually down to 28, then 25, then 22, then if I choose to keep the broadcast on even longer, down to 10FPS! But I usually stop the broadcast after around 22 because the video becomes way too choppy for my viewers and I.
- The audio becomes out of sync, and gets more and more delayed the longer I let the FMLE stream to JTV.
Here are some videos of how good it is from the start, then how bad it gets in the end...
GoW2 (360) - http://www.justin.tv/clip/4983dc87147c9fbe **I cussed a bit in this highlight. Just a warning =P
CoD4 (360) - http://www.justin.tv/clip/910b1ec95d278003 **This is after 14 minutes of idling in the lobby.
The strange thing is, that if I stop FMLE, then start it again, it will stream perfectly fine for 7-8 minutes then it will show these symptoms again, gradually getting worse. My computer is pretty good, and my CPU usage never goes over 50% while broadcasting.
Intel Core 2 Quad Q9550
4GB of RAM
Geforce GTX 260
About 3.5 Mbps upload speed (doesn't matter what my FMLE settings are put to. Even if I have a stream of only a total of 400 kbps, the quality will die down after 7 minutes)
Update: Upgraded from Vista 32-bit to Windows 7 64-bit. Still no good.
I'm going to try broadcasting with my old Dazzle DVC100 capture card and see if FMLE does the same thing. Update: FMLE indeed does the same thing and lags the broadcast, even though it worked perfectly fine on my old computer with no lag whatsoever. This cancels out the possibility of a problem with the Intensity Pro capture card. There's something wrong with my computer but I can't pin it down.
Any help is appreciated. Thanks!I watched your videos. At first look, the problem seems to be of insufficient bitrate and lack of CPU. But as you mentioned that your CPU usage never goes above 50%, cpu shouldn't be a problem. If the bitrate is insufficient you might observe choppyness in the video. When you say that the problem occurs after ~7min, do you encode the same thing everytime after 7min? I mean, as the complexity of the content increases vp6 codec will try to budget more bits for the content. If it is unable to do so, video quality will suffer. Please attach FMLE session log file of the choppy session. If you are creating a local flv file, please verify whether the problem exists in the file.

Programatically stop and start computer process
Is there a way to programatically start and stop computer processes/services using LabVIEW?
Thanks,
TaylorWhich OS? For Windows you can use System Exec to execute DOS commands to start programs. For services use the net start or net stop <servicename> commands.

FMLE encoding stopped: Problem with capture device. Incorrect samples given by the device.
Hi Support,
I am trying to use FMLE to encode and stream video from an Axis P1346 IP camera, via Axis' Streaming Assistant software, to a Wowza server.
Everyting appears to be working perfectly and the encoding and resultant stream quality is excellent. Sometimes after a few hours and sometimes after just a few minutes, the encoding will stop with the following error:
Tue Mar 26 2013 11:47:18 : Session Stopped
Tue Mar 26 2013 11:47:18 : Problem with capture device. Incorrect samples given by the device. Stopping encoding session.
I have attached a recent log of a session that only lasted a few minutes - do you have any ideas on how to resolve this instability?

Run programatically w/ stop option
I have created a vi that runs programatically, but I want it to be able to stop in the middle of running the program if the stop button is pushed.
I put the vi in a while loop and want the condition to be if stop is false. I tried to connect a local variable to the condition, among other things, but can not figure out what I need to connect to the condition if I cannot directly connect the stop button to it. Any suggestions?
EllieI want to stop the vi that I start programatically with a button on the front panel of that vi. I have attached the program this time to clarify the question.
