RTMP Store and Play 1.0

Hi guys,

after a longer time of coding I would like to share my new app.So with this app you can grab / store / edit / play / record / watch / debug and test play your RTMP streams and much more.In the app I use latest librtmp and it works similar as the rtmpdump commandline tool and you can use also almost all original rtmpdump commands (see synopsis).My main goal was it to build a tool to handle all streams at once in a GUI with a simple and quickly handling.I also added much extra features which should be helpfully to get more needed informations about streams if they don't play (special cases) or if you need to get stream datas manually.All necessary information about the app and features I wrote detailed into included text files and I also created four little videos how to use it and what to do in some special cases specially if you didn't know or worked with rtmpdump before.If yes then its of course a advantage for you.

I embedded two file into the app you do need to grab rtmp streams on fly running in your browser.Both files will created (if not present already) if you start the hook.The unhook function does restore original state back if processes are still present.The hook feature works similar as the RTMPDumpHelper tool and it does pipe the traffic to localhost so that rtmpsuck gets it without to record anything and just used to get the stream datas which you then can see in the app to work go on with them.You can use Firefox (flash hook),Chrome or InternetExplorer to use the hook function.The best choice would be Firefox and for Chrome not all sites are working (see video).

Embedded Files
-------------------------------------
- unpacked rtmpsuck.exe version (disabled record functions)
- ConnectHook.dll               (coded by me to hook processes)

System requirements
-------------------------------------
Windows x86 (32 bit)

- I coded the app in MASM (WinASM IDE) on Windows 7 and didn't test it on lower systems like XP now etc. 
- Installed VLC player
- Firefox or Chrome or Internet Explorer browser

Optional: SWF ID            (Check for running flash player / Chrome / IE / download for HMAC check)
          JPEXS Decompiler  (Find secureToken or custom command etc)

PS: Have fun with my app and maybe you will like to use it in the future so I tried my best (as good as possible for me) to create a simple and good alternative free app. :) Feedback or possible bugs reports etc are welcome of course.

Hi guys,

just wanna ask whether the app works so far for you?So someone told me that it failed with the play / record function on Windows 10 32 bit.I would like to know whether anyone else of you who is using Win 10 32 bit has same trouble or not.The person who told me about that problem is using a China language + VPN.Now I thought it could be have to do with that China language maybe.All in all the person gets 2 excetpion (I did send him a test version with exception logging),one for play and one for record.I tried to check that out and something is going wrong using CompareStringA API (called from lstrcpyA).Seems that its trying to compare with a value and not with a string.Also exception for record function is also strange so it dosent write in stack using REP MOVSB command.All in all strange so far.Problem is I cant debug that problems without having Win 10 and just wanna ask whether anyone of you who is using Win 10 32 bit could check that out to find more infos what the reason could be.Below some infos I build toghether so far....

....so if you like to check that out also if you just do use Win 10 32 bit only to make a quick test without to debug and send me results whether it work or not for you then you can use this streamlink....

-r rtmp://31.13.223.103:1935/359tv/codefashion.stream

...if you dont have any.Just add it and press play or also record to test both.

So for Win 7 32 bit I do use all is working without problems.Maybe problem is really Win 10 (any API not working right I do use maybe or protection stack issue or whatever).Maybe you can see more if you can debug that 2 issues out.

Thank you so far and till later
