  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Ffmpeg c++ can't compile with libxh264

    10 septembre 2022, par Turgut

    I made a program that uses the source version of ffmpeg. I get the code from it's website and compile/configured it. The problem is I want to configure it with the libx264 flag so it looks like this :

    


    ./configure --enable-shared --enable-libx264 --enable-gpl


    


    Ffmpeg itself compiles with no errors, however when I try to compile my own code using make I get this error :

    (The error is a bit longer but I think this is ample for now.)

    


    The thing is, this code also runs on the cloud and compiles just fine without the --enable-libx264 flags. And inside the cloud, it works just fine even with the libx264 flag. But when I follow the exact same steps as the cloud and try to compile it locally, it gives this error.

    


    Here are the steps I have followed :

    


    First I removed ffmpeg (It was a bit messy) using sudo apt-get --purge autoremove ffmpeg then I made sure its deleted by searching find / -name ffmpeg and manually deleting my findings. Then, I ran apt-get install -y libx264-dev, followed by ./configure --enable-shared --enable-libx264 --enable-gpl inside the directory where I have downloaded the source files. Then ran make and make install where ffmpeg source files are. I ran ldconfig so it can detect shared libs (This is how it works on the cloud) and finally ran make on my own codes directory and got the error mentioned.

    


    Here is my CMakeFile :

    Like I said, it works on the cloud just the way it is and everything works without the --enable-libx264 flag.

    


    How can I fix this ? I'm on ubuntu 22+

    


  • Ffmpeg c++ can't compile with libxh264

    10 septembre 2022, par Turgut

    I made a program that uses the source version of ffmpeg. I get the code from it's website and compile/configured it. The problem is I want to configure it with the libx264 flag so it looks like this :

    


    ./configure --enable-shared --enable-libx264 --enable-gpl


    


    Ffmpeg itself compiles with no errors, however when I try to compile my own code using make I get this error :

    (The error is a bit longer but I think this is ample for now.)

    


    The thing is, this code also runs on the cloud and compiles just fine without the --enable-libx264 flags. And inside the cloud, it works just fine even with the libx264 flag. But when I follow the exact same steps as the cloud and try to compile it locally, it gives this error.

    


    Here are the steps I have followed :

    


    First I removed ffmpeg (It was a bit messy) using sudo apt-get --purge autoremove ffmpeg then I made sure its deleted by searching find / -name ffmpeg and manually deleting my findings. Then, I ran apt-get install -y libx264-dev, followed by ./configure --enable-shared --enable-libx264 --enable-gpl inside the directory where I have downloaded the source files. Then ran make and make install where ffmpeg source files are. I ran ldconfig so it can detect shared libs (This is how it works on the cloud) and finally ran make on my own codes directory and got the error mentioned.

    


    Here is my CMakeFile :

    Like I said, it works on the cloud just the way it is and everything works without the --enable-libx264 flag.

    


    How can I fix this ? I'm on ubuntu 22+

    


  • FFMPEG error with avformat_open_input returning -135

    28 avril 2015, par LawfulEvil

    I have a DLL one of my applications uses to receive video from RTSP cameras. Under the hood, the DLL uses FFMPEG libs from this release zip :

    ffmpeg-20141022-git-6dc99fd-win64-shared.7z

    We have a wide variety of cameras in house and most of them work just fine. However, on one particular Pelco Model Number : IXE20DN-OCP, I am unable to connect. I tested the camera and rtsp connection string on VLC and it connects to the camera just fine.

    I found the connection string here : http://www.ispyconnect.com/man.aspx?n=Pelco

    rtsp://IPADDRESS:554/1/stream1

    Oddly, even if I leave the port off of VLC, it connects, so I’m guessing its the default RTSP port or that VLC tries a variety of things based on your input.

    In any case, when I attempt to connect, I get an error from av_format_open_input. It returns a code of -135. When I looked in the error code list I didn’t see that listed. For good measure, I printed out all the errors in error.h just to see what their values were.

    Nothing even close to -135. I did find this error, sort of on stack overflow, here runtime error when linking ffmpeg libraries in qt creator where the author claims it is a DLL loading problem error. I’m not sure what led him to think that, but I followed the advice and used the dependency walker (http://www.dependencywalker.com/) to checkout what dependencies it thought my DLL needed. It listed a few, but they were already provided in my install package.

    To make sure it was picking them up, I manually removed them from the install and observed a radical change in program behavior(that being my DLL didn’t load and start to run at all).

    So, I’ve got a bit of init code :

    void FfmpegInitialize()
    
{
    
 av_lockmgr_register(&LockManagerCb);
    
 av_register_all();
    
 LOG_DEBUG0("av_register_all returned\n");
    
}

    Then I’ve got my main open connection routine ...

    int RTSPConnect(const char *URL, int width, int height, frameReceived callbackFunction)
    
{
    

    
    int errCode =0;
    
    if ((errCode = avformat_network_init()) != 0)
    
    {
    
        LOG_ERROR1("avformat_network_init returned error code %d\n", errCode);  
    
    }
    
    LOG_DEBUG0("avformat_network_init returned\n");
    
    //Allocate space and setup the the object to be used for storing all info needed for this connection
    
    fContextReadFrame = avformat_alloc_context(); // free'd in the Close method
    

    
    if (fContextReadFrame == 0)
    
    {
    
        LOG_ERROR1("Unable to set rtsp_transport options.   Error code = %d\n", errCode);
    
        return FFMPEG_OPTION_SET_FAILURE;
    
    }
    

    
    LOG_DEBUG1("avformat_alloc_context returned %p\n", fContextReadFrame);
    

    
    AVDictionary *opts = 0;
    
    if ((errCode = av_dict_set(&opts, "rtsp_transport", "tcp", 0)) < 0)
    
    {
    
        LOG_ERROR1("Unable to set rtsp_transport options.   Error code = %d\n", errCode);
    
        return FFMPEG_OPTION_SET_FAILURE;
    
    }
    
    LOG_DEBUG1("av_dict_set returned %d\n", errCode);
    

    
    //open rtsp
    
    DumpErrorCodes();
    
    if ((errCode = avformat_open_input(&fContextReadFrame, URL, NULL, &opts)) < 0)
    
    {
    
        LOG_ERROR2("Unable to open avFormat RF inputs.   URL = %s, and Error code = %d\n", URL, errCode);       
    
        LOG_ERROR2("Error Code %d = %s\n", errCode, errMsg(errCode));       
    
        // NOTE context is free'd on failure.
    
        return FFMPEG_FORMAT_OPEN_FAILURE;
    
    }
    
...

    To be sure I didn’t misunderstand the error code I printed the error message from ffmpeg but the error isn’t found and my canned error message is returned instead.

    My next step was going to be hooking up wireshark on my connection attempt and on the VLC connection attempt and trying to figure out what differences(if any) are causing the problem and what I can do to ffmpeg to make it work. As I said, I’ve got a dozen other cameras in house that use RTSP and they work with my DLL. Some utilize usernames/passwords/etc as well(so I know that isn’t the problem).

    Also, my run logs :

    FfmpegInitialize - av_register_all returned
    
Open - Open called.  Pointers valid, passing control.
    
Rtsp::RtspInterface::Open - Rtsp::RtspInterface::Open called

DumpErrorCodes - Error Code : AVERROR_HTTP_SERVER_ERROR = -1482175992
    
RTSPConnect - Unable to open avFormat RF inputs.   URL = rtsp://192.168.14.60:554/1/stream1, and Error code = -135
    
RTSPConnect - Error Code -135 = No Error Message Available

    I’m going to move forward with wireshark but would like to know the origin of the -135 error code from ffmpeg. When I look at the code if ’ret’ is getting set to -135, it must be happening as a result of the return code from a helper method and not directly in the avformat_open_input method.

    https://www.ffmpeg.org/doxygen/2.5/libavformat_2utils_8c_source.html#l00398

    After upgrading to the latest daily ffmpeg build, I get data on wireshark. Real Time Streaming Protocol :

    Request: SETUP rtsp://192.168.14.60/stream1/track1 RTSP/1.0\r\n
    
Method: SETUP
    
URL: rtsp://192.168.14.60/stream1/track1
    
Transport: RTP/AVP/TCP;unicast;interleaved=0-1
    
CSeq: 3\r\n
    
User-Agent: Lavf56.31.100\r\n
    
\r\n

    The response to that is the first ’error’ that I can detect in the initiation.

    Response: RTSP/1.0 461 Unsupported Transport\r\n
    
Status: 461
    
CSeq: 3\r\n
    
Date: Sun, Jan 04 1970 16:03:05 GMT\r\n
    
\r\n

    I’m going to guess that... it means the transport we selected was unsupported. I quick check of the code reveals I picked ’tcp’. Looking through the reply to the DESCRIBE command, it appears :

    Media Protocol: RTP/AVP

    Further, when SETUP is issued by ffmpeg, it specifies :

    Transport: RTP/AVP/TCP;unicast;interleaved=0-1

    I’m going to try, on failure here to pick another transport type and see how that works. Still don’t know where the -135 comes from.
