Playback of low bitrate flv or f4v from live stream in FMS causes player buffer to empty

We are experiencing a consistent issue when playing a low bitrate (300kbps or less) flv in a live stream from FMS. Basically, the player will will start off with the appropriate buffer, say 5 seconds, then begin dropping until it empties out, and will have to rebuffer. We've tried with a variety of flv and f4v files, all that are 300kbps or less, and we consistently get the issue. Is this something Adobe can investigate in FMS? Or are there any suggestions on how we can get around the issue?

hey, i got the similar problem, logging like this

Remove Lag from Live Streams

I am publishing 2 live streams from a computer with 2 video capture cards in it and I get a lag every 30 seconds or so on the subscribers side. I have tried adjusting the camera quality and setMode properties but still the lag persists inside and outside the LAN, is there a way to create a buffer on the server or adjust the way the live stream is received on the subscribers side so there is no noticeable lag? I saw something about editing application.xml to adjust the queue and a suggested bitrate but not sure if this is applicable, here is the link:
http://www.adobe.com/devnet/flashmediaserver/articles/dynstream_live.html
Here is my setup:
The publishing computer:
2 PCI-e x1 cards, one takes S-Video (480i) and the other DVI (720p)
Windows 7 64bit
Intel i7
6 GB RAM'
GB NIC and Switch
From the switch is one hop to a GB router and out to a 10 MB pipe which leads to our datacenter 30 miles away. The swf on this side just gets the 2 cameras, sets the quality to (0,80) and mode to (640,480,25,false) (I have played with these settings a little) and creates 2 lives streams on the FMS.
The FMS:
I am running Flash Media Interactive Server 3.5 on my own server with two 3.6 Dual Core Xeon processors and 4 GB RAM. This server resides in a Datacenter and has a 100 MB burstable pipe. From the FMS administration console I am barely using 4MB total bandwidth, 1% CPU usage, 2% RAM.
The subscribing computer:
I have used many different types of hardwired PC's within the same LAN and outside the LAN, results are the same.
The swf on this side just creates 2 new video instances and attaches the 2 netstreams to them. They are placed side by side and the height and width of these videos are undefined.
Does anyone know where this lag could be coming from, is there any settings I can adjust to improve performance while maintaining a minimum S-Video quality level?
Thanks

Hi,
Thanks for the detailed information in your first post.
Coming to the latency... It gets affected by various factors. The stream bitrate, FMS server side settings, subscriber's client side setting and on top of these the network bandwidth.
I need to know the NetStream.bufferTime set at the subscriber's application. Try setting it to 3 when you issue the play, later you can increase it to 8 or so to stabilize the play back.
Also can you try to subscribe to single stream and check if your client bandwidth is able to play back isngle stream?
The link which you have mentioned below is a good reference to tune your server side settings.

Live streaming to FMS server from analog cable?

Need to stream an analog cable signal (may consist of 60-70
channels in VL and VHF)to FMS server. im doing a small scale
project. so i want some hardwares supporting these. please suggest
me some reasonable ones..
is it possible to do the same with a tv tuner card.?

For HLS streaming, only aac/heaac are supported audio codec. Though FMS do not disallow packaging mp3, but its mostly depnds upon ios devices to play back them.. We don't recommend mp3 as codec for ios playback.
Thanks

Configure Live streaming FLV Encodering -- Adobe -- End user

Hello,
WHile looking on the web, there are no clear cut instructions on how to configure adobe media server fro live streaming.
What I would like to do is take a streaming coming from alive flv streaming source. Have adobe media server configured to allow users to connect to the media manager and watch the live stream.
Could someone provide directions on this?
Thank you,

Hi,
Just move your image display control inside the while loop.
Also don't forget to create image buffers to feed your vision functions... Otherwise you may have some strange behavior.

Sending Live Stream from one FMS to another FMS

Hey,
Here's what I would like to do:
1. The Flash Media Encoder sends a live stream to FMS 1
2. On FMS 1, a connection to FMS 2 is set up and the live
stream is sent to FMS 2.
3. Every second, a message with metadata is sent to FMS 2
using Stream.send()
4. A Client connecting to FMS 2 receives the stream and the
metadata that was sent along with it.
I know this sounds pretty confusing, but the main problem is,
that I don't have access to the FMS 2, so I can't call
Stream.send() there. First I thought the solution would be using
Stream.play() with a remote connection, but when I call the
Stream.send() method nothing happens on the client side.
Then I thought I could do the whole thing by using a client
side application that connects to FMS 1, receives the stream,
embeds the metadata and publishes it to FMS 2. Here's the code I
used:
// Connect to FMS 1 to get stream
client_nc.connect("rtmp://localhost/encoder_stream/room_01",
"Client");
// Create input stream
in_ns = new NetStream(client_nc);
// Connect to FMS 2
akamai_nc.connect("rtmp://localhost/akamai/room_01",
"Client");
// Create new stream, feed with in_ns and send to FMS2
out_ns = new NetStream(akamai_nc);
out_ns.publish("stream");
out_ns.attachVideo(in_ns);
Unfortunately the attachVideo method only accepts a camera
and not a netstream object.
So this is where I'm standing now... anyone any ideas?
thanks

Hello,
i've asked our Akamai contact and they say it's not possible
to install any scripts on their servers. I think the only way is to
push the stream from FMS1 to FMS2, but since FMS doesn't support a
push method, there i have to find another way *sigh*
I've heard about FMS version 3 coming up soon, and I'd really
like to play around with the alpha version. Any idea where you can
get it from? On Steve Wolkoffs blog it says the new FMS is going to
support a push method:
http://blogs.adobe.com/dreaming/2006/10/fmsnext_feature_open_thread.html
I've also played around with the Red5 server, but I couldn't
find anything there to achieve a server side push method. Does
anyone have any experience with Red5 and live streaming?
Cheers!

Converting into a lower bitrate improves video playback?

Hello, I heard if you convert videos into a lower bitrate you get more hours of video playback. If thats true, what settings should i set my videora to? Instead of the default one

Hello, I heard if you convert videos into a lower
bitrate you get more hours of video playback.
The subject of the post and content of your post are asking two different questions.
As for the subject... does lowering the bitrate improve video playback?
It depends what you mean by improve. Lowering the bitrate might make the video run faster/smoother/less choppy but it will also lower the quality of the picture.
As for the message in your post... does loweing the bitrate give you more hours of video playback?
Probably, yes. The size of the video file will be smaller, so you can fit more content on the iPod. Smaller file sizes mean less work for the iPod hard drive, wich results in better battery life.

Issues with depreciating FLV and F4V video formats from Adobe Media Encoder 2004

Hi Adobe
There are a couple of issues that have come to light with the removal of FLV support from AME 2004. Please can you provide answers to the following:
How do we set up/create Flash Que Points in video, now that the FLV format has been removed for AME 2004? - This is something I use a lot for adding dynamic text to video in Flash projects.
How do we export video with Alpha, without the FLV format, which can then be used in Flash? - This typically is used to overlay presenter to camera (on green screen) on flash animations or interactions etc.
More info on these issue on the following video forums:
Re: How do I use Flash Que Markers without the ability to export to FLV or F4V in Premiere Pro CC 2014?
Re: FLV export gone.. need alpha channel in video for Flash

I know this already - what worries me is going forward, there is no alternative to using these features. Adobe has basically made the new versions of their software unusable to me and other users looking to use 'Flash Que Points' or 'Alpha in video'. What Adobe should do is provide a modern alternative, before ditching these formats. - Doesn't really make any sense!
The other big question is, for how long will they provide access to the older versions????

Working with flv anf f4v

We try to use FME to capture and stream video from different
kinds of sources. These streames are to be treated in different
ways. Sometimes they will be streamed via FMS live or/and on
demand, sometimes they will be made available for download. To
start with I want to use h.264 320x240 which should be viewable on
new phones and ipod. Idea is to provide a very simple way to
capture (and possibly live stream) video with the possibility to
enhance the recordings, if required.
I got a few questions:
1 - how can I edit flv and f4v files? Premiere CS3 won't
import them.
(I found the plugin from Moyea, but it only takes flv, not
f4v)
2 - f4v is supposed to be a mpeg4 container, but f.x
Quicktime can't open them. Does this have to do with the settings
for h.264? How can I use the h.264 video and mp3 (or AAC?) audio
without transcoding them
3 - how can I make FME ask the server to record a stream
(like NetStream.publish("astream", "record"))
Thanks for listening
Frank
PS: can the server record h.264 at all?

Some solutions I found so far
- the f4m files FME makes can contain h.264 video and mp3
audio which seems to be invalid for a mp4-container. Recording f4h
with h.264 only and renaming it to mp4 helps (not sure QT really
likes these files).
MainConcept (they deliver the h.264-codec for FME if I get
this right) sell an AAC-plugin for FME which seems to work (only
tried the demo so far; I remember a few QT-crashes though)
- super.exe from erightsoft seems to be able to open f4v and
to transcode mp3 to AAC while copying h.264
- MainConcept has a plugin for Adobe Premiere which can
import and export mp4 with h.264 and AAC (seems to have a problem
when the frame rate of the imported video is lower than the
projects frame rate). The plugin can also import mp2 with audio
from free dvd and some other formats
- MainConcept has a program called Reference with a lot of
demo-encoder which can open, trim and export f4v-files with h.264
and AAC. It comes with with several predefined profiles which seem
to work fx on iPod or Nokia E51

How to convert FLV and F4V files to other media formats

How to convert FLV and F4V files to other media formats
Nowadays, every one can download their favorite videos from video sharing websites like YouTube, Hulu, MySpace, Google Video, metacafe, Yahoo! Video, Reuters.com and so on at will. However, these video files we got are usually in the format of FLV, or F4V, which are not workable by most portable devices, or some video players and video editors on our PC. With the intention of solving these problems, this guide will show you how to convert FLV and F4V files to other video and audio formats in detail.
1. Download, install and run Pavtube FLV Converter
As soon as you run this program, the following wine red interface will show up:
2. Add files, set output format and destination folder
Input FLV and F4V files to this program by clicking on “Add” button, and select a format as the output format in the drop-down list of “Format”, meanwhile, you can press the output folder to specify the destination folder or just use the path set by default. Moreover, “merge into one file” enables you to combine multiple FLV and F4V files to be as a single file, if you have this needs, just tick it.
3. Set advanced settings
Click “Settings” button, the following interface will pop up. You can change the parameters like screen size, bit rate, frame rate, sample rate, etc. on it to optimize the output quality or compress file size.
4. Convert
After all settings are done, you can press “Convert” button to start transferring, and then the following window will show you the conversion info in detail. According to the info you can manage your time and disk space properly.
Pavtube FLV Converter can definitely complete the conversion at a swift speed with excellent quality; also it adopts an advanced audio-video sync technology, so that audio and video match very well in the resulted files. Therefore you need not worry about these issues.

Convert to lower bitrate hangs on some songs

I recently had to restore an iPod classic. While syncing, I told it to convert all songs to lower bitrate (128 kbps). I've performed this operation before without mishap, but this time, some songs appear to take MUCH longer to convert (on the order of day for an individual song). At the moment, it has restarted a sync, and it's working on song 5 of 18000. Songs 1-4 went at a normal rate, but song 5 has been working for 2 hours, with my processor (2 core i5 w/ HT) working at 300% on the iTunes process.
If I remove the song in question (something titled "Intro"), iTunes proceeds along, and hangs on another song in a similar manner. If I uncheck the requirement to convert to lower bitrate, the sync proceeds normally and all of the songs make it onto the iPod.
Is this a problem with iTunes 11? Or should I be looking at an issue with my individual files? My library is composed of a variety of formats, from 128kbps iTMS files to ALAC CD-rips. If I can avoid it, I'd like to avoid converting the whole library down to 128 or 256kbps AAC and then dealing with duplicates. Any advice?
Thanks,
Dustin

I am experiencing a similar issue with a 5th generation ipod nano.

Export to SD card for car stereo - use lower bitrate?

Okay, so my fancy new car stereo has an SD card slot, and the stereo reads a file structure so I can have folders for each Artist, and in that a flofer for each album, with MP3 files inside. I can see tha ther easiest way to populate an SD card is to copy the artist folders directly from the itunes music folder in Finder.
But... all my MP3s in iTunes are ripped at 192kbs, and to fit more on an SD card I'd like to use smaller versions.
Can't work out a way to do this easily. I can create lower bitrate verions using "create new version" but there are then stored in the same folders so I get two copies of each song. Can anyone sugegst a way of exporting a whole batch of songs (several thousand) to a new folder at a reduced bitrate?
Or converting a batch?
Or suggest some other idea to create a reduced bitrate SD card without having to look at each MP3 file idividually (which all the solutions I've considered so far seem to need).

Still not quite achieving what I'm aiming at. I've found scripts to batch-convert an export, but the newly created files are then just 'loose' in folders and not nested as artists and albums. I've found other scripts to export with the file strucure intact. But not both.

How do I burn MP3 files to CD at a lower bitrate?

I'm a newbie to Mac and to iTunes, so pardon me if this is a frequently asked question. As a former user of Windows Media Player, I am used to being able to burn my MP3 files to CD at a lower bitrate (128) than what the MP3 files saved on my computer are (320). In WMP you tell it what bitrate you want the files encoded at, it then re-encodes them, burns them to CD and then deletes the re-encoded files from the hard drive.
Am I missing something in iTunes or is this not possible? It looks like I might be able to do each step of these steps manually, but I'm not quite sure how to save the converted files to a different folder than the originals. If this is not possible in iTunes, can someone recommend a program that will do this. Thanks!

You can easily burn them into artist folders onto the CD (which is not what you previously asked).
Create the playlist.
Sort on Album or Artist and then burn it.
The songs will be put into Albums or Artists.

Ca'nt ftp longer (i.e. 4 minutes) flv or f4v files (get error message "waiting for server") I

when I ftp(i.e. "put" or "upload) short flv or f4v files using dreamweaver cs4 the files upload easily and quickly. However, when I try to ftp ("put" or "upload" ) longer (i.e. 4 minutes or longer) flv or f4v files it goes through the ftp process (seeing it in background activity screen) but at the end I always get a message "waiting on server" and the longer files don't get onto hosting server. Is there a setting I need to change or other method I need to use). I have worked with my hosting support tech person but we could not solve this problem.

I'd suggest that you try using a dedicated FTP program like Filezilla or SmartFTP.
http://filezilla-project.org/
Those programs give you much more feedback on what's happening as you attempt to upload files, including error messages, etc.
There is really no difference between uploading large files and small files, the process on the server is exactly the same..UNLESS there are limits to file size or video duration set by your host. So dispite the fact that you have worked with your host support, I'd still say that the problem is server side or being limited by your Internet service provider... unless the video files you are attempting to upload are corrupted.
You didn't say if any portion of the larger video files were uploaded...and FTP program will show you whether or not ANY of the file was uploaded and at what point it stopped. You also didn't mention how large the video files where.... sort of where the "tipping point" is in file size (video duration of course is no measure of file size).
Just to reassure you, the file size of a video file will have no bearing on your ability to FTP unless your host or ISP is limiting you in some way.
I regularly Live stream events and also record them. An 8 hr event will produce roughly 1.5GB of compressed video. I use SmartFTP, with a reputable host and can upload the entire set of 1.5GB of video files (each about 50MB) over a 1000kbps upload connection without problem. Recently during a movie production project, we uploaded a number of single video file which each where over 1GB a piece.
So there is really no problem uploading video files unless there are restriction on you account from the host or the ISP.
Best wishes,
