Play RTMP in libvlc (video in QWidget)

[braders2]

Hi guys,
I write program (QT 5.1) which will be play RTMP in libvlc. I don't know how i can to do. I always used rtmpdump for example (rtmpdump -r rtmp://94.102.63.23:443/share/gc-h2kmq -f WIN 11,9,900,152 -p http://www.sharecast.to ). But how I can play this link in libvlc? Can u help me? I read about librtmp, but I dont know where I can download this library for Windows. Video from hard disk is normally played in QWidget.

Any idea?

Why are you asking here and not on some libvlc forum?

[braders2]

I asked but unanswered. Ok can u help with rtmpdump? I found source code http://pigeonsnest.co.uk/stuff/rtmp/rtmpdump/index.html but when i compile rtmpdump.cpp in QT 5.1 show me 131 problems for example "D:\Qt\Qt5.1.1\Tools\QtCreator\bin\nienazwany4\mai n.cpp:123: błąd:undefined reference to `RTMP_LIB::RTMPPacket::RTMPPacket()'" or "D:\Qt\Qt5.1.1\Tools\QtCreator\bin\nienazwany4\mai n.cpp:138: błąd:undefined reference to `Log(int, char const*, ...)'"
Can u help me compile rtmpdump.cpp ?

I suggest that you try to tell us what exactly you are trying to do as I think you are trying to pry open doors that are already open.

[braders2]

What you mean?

[wysota]

I mean tell us why you want to use rtmpdump.

I want use rtmpdump to playbacks stream in my program (exactly in QWidget). RTMPdump.exe is separate program. I run it from my program:

QProcess* process = new QProcess();
QString program = "rtmpdump -r rtmp://94.102.63.23:443/share/gc-h2kmq -f WIN 11,9,900,152  -p http://www.sharecast.to -o stream.flv";
process->setProcessChannelMode(QProcess::MergedChannels);
process->start(program);

QProcess* process = new QProcess();
QString program = "rtmpdump -r rtmp://94.102.63.23:443/share/gc-h2kmq -f WIN 11,9,900,152  -p http://www.sharecast.to -o stream.flv";
process->setProcessChannelMode(QProcess::MergedChannels);
process->start(program);

It works but rtmpdump.exe output directs the stream to file "stream.flv". I wanna use RTMPdump.exe output directs to my program, but i don't know Can I do that. My program is run when i open RTMPdump.exe by QProcess... How I can direct rtmpdump.exe output to running my program?
Maybe u know how compile rtmpdump.cpp then will be easier...

If you have a tool that doesn't do what you want then why use it? Wikipedia claims you should rather use librtmp (http://rtmpdump.mplayerhq.hu/librtmp.3.html)

Where Can I get librtmp which will be work and compile in QT 5.1? I had 3 version and none compile in QT :/

You don't compile it "in QT", you compile it like any other C library with your compiler.

Can u tell me where I can download correctly LIBRTMP and how compile it (MinGW)? And next how use compiled LIBRTMP in QT?

librtmp is part of rtmpdump. The archive has a README file which contains information how to build the package. This has nothing to do with Qt.

It is QT project use librtmp library made by Vladimir Lushpenko when I Debug and Build show me a lot of errors, I can't Build this project. Can u tell me step by step how Build this project?

1. Unzip archive
2. Open PRO file in Qt Creator
3. Build
4. Find the first error (not warning) message and think about it.
5. I guess your first error is related to OpenSSL (I have to guess you haven't told us). It is fairly obvious that librtmp requires OpenSSL headers and libraries to build.
6. Download and install OpenSSL for Windows: http://slproweb.com/products/Win32OpenSSL.html
7. Adapt the PRO file INCLUDEPATH and LIBS variables so the compiler can find the includes and libs respectively: Declaring Other Libraries
8. Go to step 3

Search here before you come back and ask about step 7.

Thank u very much for advice i builded this project
