Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -

how to make live streaming for multiple clients
19 septembre 2014, par Abdulrahman AlcharbajiI have new project to do and I need some help to know where to start.
I have more than 1000 DVR each with 4 channels, I need to be able to do live streaming for multiple clients, and clients could be android,iPhone or windows.
Now throw searching i tried to check ffserver and ffmpeg but i couldn’t find much references to guide me throw a solution for my problem.
NOTE : the DVRs streaming with h.264 encoding.So Please can anybody help me by guiding me for a start or some good references about this particular issue.
Many Thnaks

Codec not found while H.264 encoding using FFMPEG in iOS
12 juin 2013, par Sukhpal SinghI am trying to encode video in h.264 format using FFMpeg in iOS. Actually I am receiving sample buffer from iPhone Camera and then converting it AVFrame and further from AVFrame to H.264 video. But while h.264 encoding if I use :
codec = avcodec_find_encoder(CODEC_ID_MPEG1VIDEO);Then codec is found but if I use :
codec = avcodec_find_encoder(CODEC_ID_H264);Then codec is nil means codec not found. Full code is as below :
static void encode(AVFrame *picture)
{
AVCodec *codec;
AVCodecContext *c= NULL;
int i, out_size, size, outbuf_size;
uint8_t *outbuf, *picture_buf;
printf("Video encoding\n");
/* find the mpeg1 video encoder */
//avcodec_init() ; // Also tried this but giving warning and not worked
avcodec_register_all();
codec = avcodec_find_encoder(CODEC_ID_H264);
if (!codec) {
fprintf(stderr, "codec not found\n");
exit(1);
}
c= avcodec_alloc_context();
picture= avcodec_alloc_frame();
/* put sample parameters */
c->bit_rate = 400000;
/* resolution must be a multiple of two */
c->width = 352;
c->height = 288;
/* frames per second */
c->time_base= (AVRational){1,25};
c->gop_size = 10; /* emit one intra frame every ten frames */
c->max_b_frames=1;
c->pix_fmt = PIX_FMT_YUV420P;
/* open it */
if (avcodec_open(c, codec) < 0) {
fprintf(stderr, "could not open codec\n");
exit(1);
}
/* alloc image and output buffer */
outbuf_size = 100000;
outbuf = malloc(outbuf_size);
size = c->width * c->height;
picture_buf = malloc((size * 3) / 2); /* size for YUV 420 */
out_size = avcodec_encode_video(c, outbuf, outbuf_size, picture);
NSLog(@"NSdada===%@",[NSData dataWithBytes:(const void *)outbuf length:out_size]);
free(picture_buf);
free(outbuf);
avcodec_close(c);
av_free(c);
av_free(picture);
printf("\n");
