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. -
HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

CMSampleBuffer from Replay Kit after encoding to Mpeg-TS Video is normal, Audio is corrupted
18 avril 2019, par Sos AI am trying to stream AAC encoded audio data received as CMSampleBuffer. AudioConverterFillComplexBuffer returns 0 status code.
But after passing this data to my FFMPEG HLSWriter audio is not correctly saved (short truncated signals).
Below is the sample code.static OSStatus inInputDataProc(AudioConverterRef inAudioConverter,
UInt32 *ioNumberDataPackets,
AudioBufferList *ioData,
AudioStreamPacketDescription **outDataPacketDescription,
void *inUserData)
{
KFAACEncoder *encoder = (__bridge KFAACEncoder *)(inUserData);
UInt32 requestedPackets = *ioNumberDataPackets;
if(requestedPackets > encoder.cycledBuffer.size / 2)
{
//NSLog(@"PCM buffer isn't full enough!");
*ioNumberDataPackets = 0;
return -1;
}
static size_t staticBuffSize = 4096;
static void* staticBuff = nil;
if(!staticBuff)
{
staticBuff = malloc(staticBuffSize);
}
size_t outputBytesSize = requestedPackets * 2;
[encoder.cycledBuffer popToBuffer:staticBuff bytes: outputBytesSize];
ioData->mBuffers[0].mData = staticBuff;
ioData->mBuffers[0].mDataByteSize = (int)outputBytesSize;
*ioNumberDataPackets = ioData->mBuffers[0].mDataByteSize / 2;
return noErr;
