  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • YUY2 image ==>>sws_scale ==>>x264_encoder_encode doesn't work in Windows

    8 décembre 2011, par shiju sasi

    I have a multi media app in Windows using x264 built using MSYS-MingW and ffmpeg Windows binaries. This works for most of the cameras which capture data in RGB24 and RGB32 formats in most of the OSes. But when I tested the app on a Windows 7 (64 bit OS) Sony Vaio Laptop which has an integrated webcam capturing in YUY2 format, the x264_enoder_encode crashes. The sws_scale to convert the YUY2 data to YUV420 Planar any way works fine here too and returns proper stride values. Please check the relevant code fragments that I have attached below.

         x264_param_apply_profile(&m_param, "baseline");
    
       m_pEncoder = x264_encoder_open(&m_param);
    
       x264_encoder_parameters(m_pEncoder,&m_param);
    

    
       m_encoderConvertCtx = sws_getContext(g_iWidth, g_iHeight, PIX_FMT_YUYV422, SCALE_WIDTH, SCALE_HEIGHT, PIX_FMT_YUV420P, SWS_BICUBIC, NULL, NULL, NULL);
    

    
       x264_picture_t m_pic_in, m_pic_out;   //X264 picture variables to get the X264 encoded picture out.
    
       x264_picture_init(&m_pic_in);
    
 m_pic_in.i_type = X264_CSP_I420;
    

    
 x264_nal_t*  m_nals;
    

    

    
 srcstride = g_iWidth * 2;  //For YUYV422 Packed
    

    
 AVFrame* pictIn;
    
 AVFrame* pictOut;
    

    
 int iInBytes = avpicture_get_size(PIX_FMT_YUV420P, SCALE_WIDTH, SCALE_HEIGHT); 
    
 uint8_t* outbuffer = (uint8_t*)av_malloc(iInBytes); 
    
 pictOut = avcodec_alloc_frame(); 
    

    
 avpicture_fill((AVPicture*)pictOut, outbuffer, PIX_FMT_YUV420P, SCALE_WIDTH, SCALE_HEIGHT); 
    

    
 sws_scale(m_encoderConvertCtx, &in_buf, &srcstride, 0, g_iHeight, pictOut->data, pictOut->linesize); //Scale from YUYV422 Packed to YUV420 Plane
    

    

    
///Code after Scale begins
    

    
memcpy(m_pic_in.img.plane[0],pictOut->data[0],SCALE_WIDTH * SCALE_HEIGHT);
    
memcpy(m_pic_in.img.plane[1],pictOut->data[1],SCALE_WIDTH * SCALE_HEIGHT/4);
    
memcpy(m_pic_in.img.plane[2],pictOut->data[2],SCALE_WIDTH * SCALE_HEIGHT/4);
    
m_pic_in.img.plane[3] = 0; 
    

    
for(int iPlane = 0; iPlane < 3; iPlane++)
    
{
    
 m_pic_in.img.i_stride[iPlane] = pictOut->linesize[iPlane];
    
}
    
m_pic_in.img.i_stride[3] = 0;
    

    
int frame_size = x264_encoder_encode(m_pEncoder, &m_nals, &i_nals, &m_pic_in, &m_pic_out);

    Please help if possible, as this has been consuming a lot of time at my end. But I am not able to dig in to the library side for debugging. Any experienced hands are requested to assist.

  • FFMPEG permission in windows wamp

    15 octobre 2011, par shababhsiddique

    I am trying to build a video sharing site using drupal 6. One of the modules i am using is ffmpeg , it requires me to set a ffmpeg binary file location . I downloaded ffmpeg from here

    http://ffmpeg.arrozcru.org/autobuilds/ffmpeg/mingw32/static/

    I placed it on C :\ffmpeg\bin\ffmpeg.exe and gave this path with the slashes changed to /

    it got the encoders information .. but i cant test it. It shows a message like

    Fmpeg failed to create an output file. This could be due to permission problems or an error from the encoding settings.

    I found that i need permission. How do i set permission ? i am using wamp on windows. Please help urgent.

  • Multi bitrate live HLS with FFmpeg on Windows

    16 mai 2014, par Nioreh

    I am trying to encode a live stream into Apple HLS for iPhone on windows. I was looking at different options and wowza can do it, but doesn’t support CDN distribution of HLS as far as I can see. Plus it costs a lot of money.

    What I did find was this site : http://www.espend.de/artikel/iphone-ipad-ipod-http-streaming-segmenter-and-m3u8-windows.html

    I can now set up a single bitrate stream easily, but my goal is an adapive multi-bitrate live stream. Is it possible ? For VOD content it can easily be accomplished with creating the different qualities then linking to them in a new m3u8, but how would this be done in live ?

    I can of course set up three quality live streams and link to them in an m3u8, but how will I get them GOP-aligned in this case ?

    My initial thought was to have one ffmpeg instance create all qualities and re-stream those outputs to new ffmpeg-instances that just remux and pipe to the segmenter. But I would need some way of streaming locally between instances. Can that be done ?

    If anyone has a nice solution to this, or can link to other software capable of live HLS on windows, I would appreciate any input.

    Have a great day !
    Regards
    Carl
