Years ago, I created a SWF application that enabled users to perform online video chat. It used simple SMTFP publish/play method to stream video. Now a few years passed and i am trying to create a backward compatible SWF application.
My problem status:
New version fails to play the streams that are published from the old swf. It
connects to server and to the publisher, but it cannot play and gives
the NetStream.Play.Failed error.
New version plays the streams that are published from its own version.
Online players like in this
guide can play my new version, but they are unable to play
streams from my old version.
I tried it with different SDKs (3.6, 4.1, 4.6) and they all fail to play the old swf streams.
I searched the web for the error and documents don't clear anything and they are just saying that it is a general error. There is question in SO that could be related, but it has no answers.
Does anyone know the reason? or any suggestions?
Are you sure that the same publication names are used in both applications? It is possible that you publish a stream with name "test1" for example and the player try to play the stream with name "test2".
Otherwise if you think that the names are correct you can try with MonaServer, it is our own open source server. It supports RTMFP, RTMP[E], HTTP and Websocket (also RTSP for testing only). Install it on your computer/server and check the log to see what's going on.
I found the problem. It seems like the flash player has changed RTMFP protocol in 11.1 version. There is not much documentation about it and as far as i can understand, I should either upgrade all the flash players or I should upgrade all of the old applications to flex 4 sdk.

I have read a question similar to this one, but years ago. I just want to know if there is now an option or some code to put in my Unity app to run Skype from HoloLens.
I have tried putting the Skype uri by code, but it only works on my PC, not on my HoloLens. It just exit my App and I have to open Skype manually, so it is not the thing I really want.
Anyone knows what to do?
You cannot open up or run Skype from within your own app. It works on your Desktop because that Skype is the full release version. The Skype app that is on the HoloLens is essentially just a beta version and doesn't contain all the features and the Skype URI would be one of the features that it doesn't have.
The only workaround there currently is, is to invoke Cortana to do it for you since you can do that through scripting and it basically is what you described as what you don't want to do.
Sorry, currently it is still not possible.
I developed an app that'll stream a rtmp video. Before I used VitamioBundle-master. I upload my app in play store it shows some warning message for upgrading my app that has to use vitamio latest version. I download it from the link shown in that alert message. Now I develop the app using vitamio 5.0.2 downloaded from the link https://www.vitamio.org/en/Download/. Once I upload the app play store shows the same alert message
Security alert
Your app utilizes a version of Vitamio, a multimedia library used for playing various types of media files, containing a security vulnerability.
Please upgrade your app(s) as soon as possible and increment the version number of the upgraded APK. Beginning 14 March 2016, Google Play will block publishing of any new apps or updates that use pre-5.0 versions of Vitamio.
The vulnerability was addressed in Vitamio v5.0. The latest versions of Vitamio can be downloaded on the Vitamio website. You can confirm your Vitamio version by checking if the SDK includes libs/armeabi-v7a/libvinit.so or libs/armeabi/libvinit.so. If either file is present, the SDK needs to be upgraded. For help upgrading, see the Vitamio support documentation. If you’re using a 3rd party library that bundles Vitamio, please notify the 3rd party and work with them to address this.
To confirm you’ve upgraded correctly, submit the updated version to the Developer Console and check back after five hours. If the app hasn’t been correctly upgraded, we will display a warning.
The vulnerability is due to the Vitamio SDK containing world-writable code. For more information about the vulnerability, please see this NowSecure blog post. For other technical questions, you can post to Stack Overflow and use the tags “android-security” and “vitamio.”
While these specific issues may not affect every app that uses Vitamio, it’s best to stay up to date on all security patches. Apps with vulnerabilities that expose users to risk of compromise may be considered in violation of our Malicious Behavior policy and section 4.4 of the Developer Distribution Agreement.
Apps must also comply with the Developer Distribution Agreement and Developer Program Policies. If you feel we have sent this warning in error, contact our policy support team through the Google Play Developer Help Center.
I gone through several solutions mentioned in different tutorial but not yet get a clear idea. Can anyone tell me the step by step procedure for updating my vitamio sdk version, or else is there any other lib for streaming rtmp video in my Android app?
Unfortunately, Vitamio 5.0.2 added back the old libvinit.so file, so it gets flagged as an old version of Vitamio. You can just delete libvinit.so and it should work.
Before converting Flash into iPhone app, I still need to understand some questions.
1) Is the converted app able to read XML code from the website like RSS or custom script?
2) 3rd party API are not allowed to be download but assets like Images, sounds or reading data from MySQL db is allow?
3) Anyone port from Flex 4 yet?
1) Yes. Almost all of the regular Flex and AIR APIs still work.
2) Yes. You can download assets just not load and run them.
3) You can package a Flex 4 app for iOS but performance and usability may not be great right now. The engineering team working on fixing that.

I'm creating a Qt Symbian application and need to connect to internet. In some way I need to let the user choose a connection when the app starts. I could use Qt Mobility to get it working but when Nokia approves I wan't do publish my application on Ovi Store. As the Qt Mobility is not included in Qt 4.6 it might be a problem to publish my app later. So for this reason I'm thinking of using native APIs instead.
The idea is to use: qt_SetDefaultIap() to set the connection on start. I have been looking at this to actually understand what it is doing. If I have two connections that the app could use, one with WIFI and one through mobile internet, which one will qt_SetDefaultIap() choose? And can I in some way with native api make the user choose a connection on start up? (qt_SetDefaultIap seems to just set a default connection on its own, without user choice)
Thanks!
Qt 4.7 is now released, and although not all of the Mobility APIs have made it into the core, QNetworkSession has.
Mrbiggerm: it looks like you've found the sym_iap_util.h file that's included in the QFtp example code in the Qt SDK. Rather than calling qt_SetDefaultIap(), try calling qt_OfferIapDialog(), and passing its return value to qt_SetDefaultIapName(). That should do what you're after. (Although this is a bit of a hack, it's often a preferred option as it presents a native S60 UI rather than making you implement your own list of access points.)
Do you expect to finish your program before Qt 4.7 release (I don't know the exact release date, but I'd estimate it will be around July), which AFAIK will contain Qt Mobility?
If the answer is no, don't worry about releasing issues, use custom build of QtMobility for development, wait for 4.7 and don't worry about releasing issues.
If the answer is yes, what stops you from deploying your program with custom QtMobility build? Internally it uses the same native API calls you want to use, not some super secret Nokia API, so there should be no problem with code validation (in fact, there will probably be less problems, since you won't have a chance to screw up code covered by QtMobility libraries).
I would like to do some japanese text to speech on my dedicated windows 2003 x64 server with .net framework, using c#
I found something on google, but requires to install a lot of files on the server... i don't like, for stability issues: there is another option, like a linked dll or something?
You can use Microsoft Speech SDK. It's a set of COM APIs containing TTS and SR engines. I'm not sure if it contains Japanese TTS though.
What you most likely want is the Microsoft Speech Server especially if your webite is going to encounter any decent load or volume.
From the site:
"A speech platform, MSS contains all
the server components for deploying
telephony (voice-only) and multimodal
(voice/visual) applications. MSS
combines Web technologies,
speech-processing services, and
telephony capabilities into a single
system. "
There is also a dedicated Microsft Speech community which will likely help you get started in this realm. Also, I'm not sure what the latest version is...2004 R2?
This article has a decent diagram outlining the various components. Looks like a good fit for integration with an ASP Web Application.
using SAPI in an ASP.NET website, is impossible: the sound will be reproduced on the server :S
It seems that there is the need of Microsoft Speech Server
...
Or not? With asp.net is possible to run a commandline exe on the server to save an mp3, then stream that mp3, right? (how to do that? i will try to figure it)
I will go this way, i let you know the result :)
edit: this is how i solved:
How to save text-to-speech as a wav with Microsoft SAPI?
I save the generated voice in a wav file, then i embed it on the page, playing it in a flash player
COOL!!
Use Microsoft Speech Library and see this article Text to Speech with the Microsoft Speech Library and SDK version 5.1 in CodeProject. Also see Giving Computers a Voice in Coding4Fun
The System.Speech.Synthesis namespace has been part of the framework since .NET 3.0. However, it has internal dependencies on the Speech SDK COM libraries (it chooses the correct version depending on the host OS), so I would recommend prototyping the work before you jump in.
The class you should probably look at first is System.Speech.Synthesis.SpeechSynthesizer (whitepaper and example code)
Warning: I have personally experienced issues using the speech APIs in an ASP.NET environment whereby the request that returned the audio data never returned. Despite heavy debugging I was never able to resolve the issue and the feature was dropped. I have had an unresolved support case with Microsoft for 12 months now.
