Amélioration de la version de base

13 septembre 2013

Jolie sélection multiple
Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)
Menus personnalisés

14 novembre 2010, par kent1

MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)
Le plugin : Gestion de la mutualisation

2 mars 2010, par kent1

Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
Installation basique
On installe les fichiers de SPIP sur le serveur.
On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :
< ?php (...)

Gstreamer pipeline to scale down video before streaming

20 novembre 2014, par r3dsm0k3
Here is what Im trying to achieve.

Im streaming from a Logitech C920 camera on beaglebone black with gstreamer. I have to save a copy of the video saved locally while it is streaming. I have achieved that with tee.
Logitech camera gives h264 encoded video at a certain bitrate, mostly very high.

Im streaming from a moving car on 3G, and the network is not good enough to send the stream to nginx-rtmp server Im using to re-distribute thus gives strong artifacts in the result.

Im able to alter the bitrate of captured video using uvch264.
But then, the locally saved video also would have lower bitrate.

Is there anyway of capturing a higher bitrate 1080p video from the camera and sending a lower resolution, lower bitrate video the streaming server ?

Following is the pipeline I have currently.
```
gst-launch-1.0 -v -e uvch264src initial-bitrate=400000 average-bitrate=400000 iframe-period=3000  device=/dev/video0 name=src auto-start=true  src.vidsrc ! queue ! video/x-h264,width=1920,height=1080,framerate=30/1 ! h264parse ! flvmux streamable=true  name=flvmuxer ! queue ! tee name=t ! queue ! filesink location=/mnt/test.flv t. ! queue ! rtmpsink location=$SERVER/hls/$CAM1
```
I could also try sending the higher bitrate video to a udpsink instead of rtmpsink and with another gstreamer process parallely and takes the data using a udpsink and probably post process/ re-encode and send to rtmp server.

Im also limited by the processing speed BeagleBone has to do for encoding the videos. Currently Im trying for 1 camera and in the finished project I would like to have 2 cameras connected. Upload speed Im getting for the network is under 1Mbps.

How do I solve this with less load on the BeagleBone ? Im very open to a new architecture as well.

ffmpeg stream decoding - artefacts when not using ffplay

18 décembre 2018, par Lucker10

I stream a video capture via RTP using libx264. For now, I just stream to localhost.
For watching the stream, I use the ffmpeg library. When I set the GOP size greater than 1 (only I frames), I get artefacts on the receiver side . The strange thing is, when I use ffplay, the image is perfect . What am I doing wrong ?

Settings for encoding

output_codec_ctx->bit_rate = 5000000;

output_codec_ctx->width = 1920;

output_codec_ctx->height = 1080;

output_codec_ctx->time_base.den = 30; // frames per second

output_codec_ctx->time_base.num = 1;

output_codec_ctx->gop_size = 10; // gop size

output_codec_ctx->max_b_frames = 0; // B frames

output_codec_ctx->pix_fmt = AV_PIX_FMT_YUV420P; // output pixel format

output_codec_ctx->codec_type = AVMEDIA_TYPE_VIDEO;



av_opt_set(output_codec_ctx->priv_data, "preset", "ultrafast", 0);

av_opt_set(output_codec_ctx->priv_data, "tune", "zerolatency", 0);

Code for decoding

AVFormatContext *pFormatCtx;

AVCodecContext *input_codec_ctx;

AVCode *pCodec;

avdevice_register_all(); // for device

avformat_network_init();

pFormatCtx = avformat_alloc_context();

AVDictionary *options = nullptr;

av_dict_set(&amp;options, "protocol_whitelist", "file,udp,rtp", 0);

av_dict_set(&amp;options, "fflags", "nobuffer",0);



avformat_open_input(&amp;pFormatCtx, "rtp://127.0.0.1:49990", nullptr, &amp;options);



avformat_find_stream_info(pFormatCtx, nullptr);

for (uint i = 0; i &lt; pFormatCtx->nb_streams; i++)

 {

   if (pFormatCtx->streams[i]->codecpar->codec_type == AVMEDIA_TYPE_VIDEO)

   {

     videoStream = static_cast<int>(i);

     break;

   }



 }



av_read_play(pFormatCtx);    //play stream

pCodec = avcodec_find_decoder(pFormatCtx->streams[videoStream]->codecpar->codec_id);

AVCodecParameters *codec_param = pFormatCtx->streams[videoStream]->codecpar;

avcodec_parameters_to_context(input_codec_ctx, codec_param);

avcodec_open2(input_codec_ctx, pCodec, nullptr);



AVPacket packet;

AVPacket *pkt  = &amp;packet;

AVFrame *frame;

frame = av_frame_alloc();



av_init_packet(pkt);

pkt->data = nullptr;    // packet data will be allocated by the encoder

pkt->size = 0;



while(true){

    av_read_frame(pFormatCtx,pkt);

    avcodec_send_packet(input_codec_ctx,pkt);

    avcodec_receive_frame(input_codec_ctx,frame);

Mixed audio and video HLS

26 décembre 2018, par Andrey Pogorelov

There is video (without audio) and audio in a separate file. It is necessary to connect this video and audio to a stream and give it to the user in the form of an HLS stream or something else. Something like YouTube, there is video in 1080 quality - without audio mixed with audio track. Video and audio do not need to transcode, just mixed, so that the processor doesnt be used. Maybe you can do something like regular nginx tools ?
