librtmfp's Issues

Unable to bind [::], ipv6 will not work : I/O error (value=true) hello Unable to bind localhost, ipv4 will not work : I/O error (value=true)

what is this?

Failed to publish big i-frames

I'm trying to publish big_buck_bunny, to a RTMFP NetGroup, with FFmpeg+librtfmp. When FFmpeg encounters big i-frames, it fails to publish, resulting bad images in Flash players.

FFmpeg publish

./ffmpeg -re -i big_buck_bunny_720p_h264.mov -c:v libx264 -c:a aac -b:v 1000k --netgroup G:027f0201010103010c020e61011b00 -f flv rtmfp://<IPv6Address>:1935/live/test

Everything works well until a big i-frame occurs. Seems that librtmfp cannot transmit big user data chunk correctly, and fail to send big i-frames.

TestClient

ffmpeg -i big_buck_bunny_720p_h264.mov -c:v libx264 -c:a aac -b:v 1000k -f flv test.flv
./TestClient --p2pWrite --url=rtmfp://<IPv6Address>/live/test --netgroup=G:027f0201010103010c020e61011b00 --logFile=testPubli.log --mediaFile=test.flv

Using your Flash VideoPlayer: http://raspi.monaserver.ovh/MonaClients/VideoPlayer/

TestClient repeatedly outputs DEBUG Main.c[176] Buffer too short, increasing...
And finally, when it encounters the first big i-frame, TestClient exits, with following log.
Players can not even see the river's flow.

Do you hava sample for play rtmfp stream

Do you have a sample for play rtmfp stream?
when I exceute such script below:
TestClient --p2pWrite --url=rtmfp://127.0.0.1:1985/live/G001 --netgroup=G:027f0201010103010c050e47313030011b00 --logFile=testPublihFlvGroup.log --mediaFile=1.flv

then I input params in http://raspi.monaserver.ovh/MonaClients/VideoPlayer/
url = rtmfp://127.0.0.1:1985/test123
groupName=G001
netgroupid=G:027f0201010103010c050e47313030011b00
then start connect

the log show below, it seems work ok,but I can not display video.

Unable to build. librtmfp not found using pkg-config

When trying to build ffmpeg with librtmfp on a RaspberryPi 4 running Raspbian 10, configure gives me an error message telling me that librtmfp can not be found.
Manually checking the version using pkg-config returns a version number higher than the required version.

I simply followed the installation instructions. Is there anything I am missing?

Compile librtmfp as static on Linux

Hi there, is it possible to compile librtmfp.a? I tried to compile ffmpeg as static
but obviously it needs librtmfp compiled as static too.
Thanks!

why TestClient NO TIME CONTROL; Please tell me how to deal it.

differences between external librtmp and ffmpeg builtin librtmp, what about librtmfp?

I just discovered a defect on ffmpeg builtin librtmp, I opened a ticket at ffmpeg bug tracker for this matter.
Description:

builtin ffmpeg librtmp does not recognize sub applications int the URL path, for example
rtmp://host:port/app/stream is ok but rtmp://host:port/app/subapp/stream is not ok althought it's a perfectly valid rtmp URL. External librtmp follows the specis and accept as many as possible sub applications needed in the URL path.

What about librtmfp? is it following the specs or has the same behavior of the ffmpeg builtin librtmp?

Segmentation fault

I'm stressing the rtmfp server by librtmfp. the main codes is:

int main(int argc,char * argv[]){   
    int flag = 1;
  
    snprintf(url, sizeof(url), "%s", url_flv + 6); // url_flv is a address of a rtmfp server. 

    RTMFP_Init(&config, &groupConfig, 1); 
    config.pOnSocketError = onSocketError;
    config.pOnStatusEvent = onStatusEvent;
    config.isBlocking = groupConfig.isBlocking = 1;
    RTMFP_InterruptSetCallback(IsInterrupted, NULL);    

    unsigned int context_keep = 0;
    unsigned int context = 0;
    context_keep = RTMFP_Connect(url, &config);    
    if (context_keep != 0) {
        try_again:
            context = RTMFP_Connect(url, &config);    
            if (context != 0) {
                RTMFP_Close(context);
                goto try_again;
            } else {
                RTMFP_Close(context_keep);
                RTMFP_Terminate(); 
                return -1; 
            }   
    }   
    RTMFP_Close(context_keep);

    RTMFP_Terminate(); // To ensure that invoker is dead
    printf("End of the Program!\n");

    return 0;

The running result is:

ERROR: librtmfp not found using pkg-config

I'm trying to compline this project in the docker, but it failed on creating the configuration for the ffmpeg.

ERROR: librtmfp not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

My device only support ipv4,how to change ipv6 to ipv4

I change" hostAddress(IPAddress::IPv6) "to" hostAddress(IPAddress::IPv4) " and change " _id = ::socket(AF_INET6, type, 0);" to " _id = ::socket(AF_INET, type, 0);" but it is not OK.

Compile with openssl 3.0 or how to target a legacy openssl path

Hi Thomas,

Hope you're fine! I just realized that Fedora 37 does not have openssl 1.1.x anymore, only openssl 3.x.
giving me some doubt about rtmfp protocol which need I guess for ever the openssl 1.1.x right?
so I installled a legacy openssl 1.1.x let's say in /usr/local/openssl-1.1 folder but how to compile with this path?

thanks

https://github.com/rdp/ffmpeg-windows-build-helpers/blob/master/patches/rtmfp.static.cross.patch

you can ignore the stuff about mingw threading, that's just because I hadn't built the compiler with builtin threading.

In addition, it's pretty hard to build a static library in linux/OS X today too, FWIW. Thanks!

unable to cross compile on linux

Because linux is case sensitive, I get this failure:

sources/Base/IPAddress.cpp:22:10: fatal error: Iphlpapi.h: No such file or directory

(if I remove the capitalization it works fine). compiling on windows or OS X works OK though :)
