Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang 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. -

How to encode video using ffmpeg-java on Android from Bitmaps ?
15 décembre 2011, par gtcompscientistI am using
ffmpeg-java
compiled for Android to encode/decode video for my application.The problem that I've run into is that I am currently getting each frame as a
Bitmap
(just a plainandroid.graphics.Bitmap
) and I can't figure out how to stuff that into the encoder.Here is the code that I am using to instantiate all the ffmpeg libraries :
AVCodecLibrary cLibrary = AVCodecLibrary.INSTANCE;
cLibrary.avcodec_register_all();
cLibrary.avcodec_init();
AVFormatLibrary fLibrary = AVFormatLibrary.INSTANCE;
fLibrary.av_register_all();
//AVUtilLibrary uLibrary = AVUtilLibrary.INSTANCE;
//uLibrary.av_malloc();
AVCodec pCodec = cLibrary.avcodec_find_encoder(AVCodecLibrary.CODEC_ID_H263);
if (pCodec == null)
{
Logging.Log("Unable to find codec.");
return;
}
Logging.Log("Found codec.");
AVCodecContext codecCtx = cLibrary.avcodec_alloc_context();
codecCtx.bit_rate = 64000;
codecCtx.coded_width = VIDEO_WIDTH;
codecCtx.coded_height = VIDEO_HEIGHT;
codecCtx.time_base = new AVRational(1, VIDEO_FPS);
codecCtx.pix_fmt = AVCodecLibrary.PIX_FMT_YUV420P;
codecCtx.codec_id = AVCodecLibrary.CODEC_ID_H263;
//codecCtx.codec_type = AVMEDIA_TYPE_VIDEO;
if (cLibrary.avcodec_open(codecCtx, pCodec) < 0)
{
Logging.Log("Unable to open codec.");
return;
}
Logging.Log("Codec opened.");This is what I want to be able to execute next :
cLibrary.avcodec_encode_video(codecCtx, pPointer, pFrame.size(), pFrame);
But, as of now, I don't know how to put the Bitmap into the right piece or if I have that setup correctly.
A few notes about the code :
-VIDEO_WIDTH
= 352
-VIDEO_HEIGHT
= 288
-VIDEO_FPS
= 30 ;
- I'm unsure about howpPointer
andpFrame
are handled. -
Need to get audio video structure for automation ffmpeg or ffprobe
10 mai 2012, par Sapan DoshiI need to get video audio stream information in separate form.
I have tried ffprobe and mediainfo, but they give full information which needs to be parsed.
I think there could be option like, where I do not need to parse the full information and get required data.
$ffprobe -XXX
audio channels 8$ffprobe -YYY
video_resolution 512x288Can anybody help with this.

How the seek frame while playing video ?
16 mars 2012, par shermanI try do this :
void Java_ffvideo_company_com_NativeCalls_seekFrame(
JNIEnv *env, jobject this, jint time) {
if (avformat_seek_file(pFormatCtx, videoStream, 0,time,time, AVSEEK_FLAG_ANY) < 0)
__android_log_print(ANDROID_LOG_DEBUG, "ERROR SEEK->>>",
"av_seek_frame failed.");
avcodec_flush_buffers(pCodecCtx);
}But the application crashes. Without
avcodec_flush_buffers
video seeking not correctly. How I can resolve this isssue ?
