Amélioration de la version de base
13 September 2013Jolie 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 (...)

license should be the type of license
22 August 2015, by sgilroylicense should be the type of license
Follow convention to make it easier for automated license checking utilities to determine which license is used. The license property in bower.json should be the SPDX type of license, in this case "MIT", instead of the URL of the license file.
Closes #544.

FFmpeg: Jpeg file to AVFrame
24 October 2012, by darjaI need to join several jpg files into video using FFmpeg library. But I have a problem with reading this files. Here is a function which reads image file and makes AVFrame:
AVFrame* OpenImage(const char* imageFileName)
{
AVFormatContext *pFormatCtx;
if(av_open_input_file(&pFormatCtx, imageFileName, NULL, 0, NULL)!=0)
{
printf("Can't open image file '%s'\n", imageFileName);
return NULL;
}
dump_format(pFormatCtx, 0, imageFileName, false);
AVCodecContext *pCodecCtx;
pCodecCtx = pFormatCtx->streams[0]->codec;
pCodecCtx->width = W_VIDEO;
pCodecCtx->height = H_VIDEO;
pCodecCtx->pix_fmt = PIX_FMT_YUV420P;
// Find the decoder for the video stream
AVCodec *pCodec = avcodec_find_decoder(pCodecCtx->codec_id);
if (!pCodec)
{
printf("Codec not found\n");
return NULL;
}
// Open codec
if(avcodec_open(pCodecCtx, pCodec)<0)
{
printf("Could not open codec\n");
return NULL;
}
//
AVFrame *pFrame;
pFrame = avcodec_alloc_frame();
if (!pFrame)
{
printf("Can't allocate memory for AVFrame\n");
return NULL;
}
int frameFinished;
int numBytes;
// Determine required buffer size and allocate buffer
numBytes = avpicture_get_size(PIX_FMT_YUVJ420P, pCodecCtx->width, pCodecCtx->height);
uint8_t *buffer = (uint8_t *) av_malloc(numBytes * sizeof(uint8_t));
avpicture_fill((AVPicture *) pFrame, buffer, PIX_FMT_YUVJ420P, pCodecCtx->width, pCodecCtx->height);
// Read frame
AVPacket packet;
int framesNumber = 0;
while (av_read_frame(pFormatCtx, &packet) >= 0)
{
if(packet.stream_index != 0)
continue;
int ret = avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
if (ret > 0)
{
printf("Frame is decoded, size %d\n", ret);
pFrame->quality = 4;
return pFrame;
}
else
printf("Error [%d] while decoding frame: %s\n", ret, strerror(AVERROR(ret)));
}
}This causes no error but creates only black frame, no image. What is wrong?
