Diogene : création de masques spécifiques de formulaires d’édition de contenus
26 octobre 2010, parDiogene est un des plugins ? SPIP activé par défaut (extension) lors de l’initialisation de MediaSPIP.
A quoi sert ce plugin
Création de masques de formulaires
Le plugin Diogène permet de créer des masques de formulaires spécifiques par secteur sur les trois objets spécifiques SPIP que sont : les articles ; les rubriques ; les sites
Il permet ainsi de définir en fonction d’un secteur particulier, un masque de formulaire par objet, ajoutant ou enlevant ainsi des champs afin de rendre le formulaire (...) -
Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

Audio object type 3 is not supported
3 octobre 2013, par ArdoramorI am running into an issue with a custom-built ffmpeg. Basically, its a vanilla ffmpeg with x264 and fdk-aac libs enabled. I am feeding an SDP file through ffmpeg API and get the following error while passing the info to
avcodec_open2:Audio object type 3 is not supported
My SDP file :

I also see the error reported for not finding codec parameters for stream 1 :
Could not find codec parameters for stream 1 (Video : h264) : unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' optionsHowever, I think that is due to me not running an actual rtp at the moment of the test.
In any case, what may be the reason for getting audio object type 3 not supported exception ?

fdk-aac - 0.1.2
So it seems that the same .sdp file causes Audio object type 3 error with my build but not with static but I really do not see what causes it (granted I am not an expert with ffmpeg API and may simply miss important details).
Simplified code for opening .sdp file that doesn't include error checks and logic separation :
AVFormatContext *inputContext = NULL;
av_register_all();
avformat_network_init();
avformat_open_input(&inputContext, "test.sdp", NULL, NULL);
avformat_find_stream_info(inputContext, NULL);
int inAudioStreamIdx = av_find_best_stream(inputContext, AVMEDIA_TYPE_AUDIO, -1, -1, NULL, 0);
AVStream *st = inputContext->streams[inAudioStreamIdx];
AVCodecContext *dec_ctx = st->codec;
AVCodec *dec = avcodec_find_decoder(dec_ctx->codec_id);
avcodec_open2(dec_ctx, dec, NULL); // Fails here with Audio object type 3Am I opening the sdp input improperly ?

When using ffmpeg api, the encoded gif is output to the dynamically applied buffer
5 septembre 2023, par yangjinhui2936Purpose：I want to use ffmpeg to encode data from rbg8 to gif format.Currently can be encoded into file output.

Tried The content in the macro definition is the relevant solution I found online. Unfortunately, the data I got is in original rgb8 format, not in gif format.ffmpeg writes data to file and Data dumped from buffer
The data dumped from the buffer seems to have no gif header


My expected result I want to output the encoded gif directly to the buffer，but i don't know what to do.
