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. -

Why does avcodec_fill_audio_frame return -22 when only sample count is different ?
24 juillet 2017, par N0unMy problem is very fast to explain : I have to encode audio samples using FFmpeg (raw PCM to G.711 mu-law). This is the guilty part of my code (I put raw parameters in this example to be explicit) :
AVFrame* frame = av_frame_alloc();
frame->nb_samples = 8000;
frame->format = AV_SAMPLE_FMT_S16;
frame->channels = 1;
frame->channel_layout = AV_CH_LAYOUT_MONO;
frame->sample_rate = 8000;
frame->quality = 1;
int res = avcodec_fill_audio_frame(frame, 1, AV_SAMPLE_FMT_S16, /*my samples data*/, 16000, 0);
// If res >= 0, continue with avcodec_encode_audio2And it works :) ... Well, I mean...
When my input is 8000 audio samples (S16 format so 16000 bytes), it works. But when I have 6000 audio samples (still S16 format so 12000 bytes), it fails with a -22 (invalid parameters). Any idea ?
PRECISION : This sample count is not dynamically changing. I have sessions with data always composed by 8000 sample (and it works), and other sessions with data always composed by 6000 sample (and it fails). Sample count and data size are the only parameters that are not the same between these sessions.
EDIT : If I set or not the
frame_size
field inAVCodecContext
, it returns to 0 afteravcodec_open2
but the mu-law encoder selected has theAV_CODEC_CAP_VARIABLE_FRAME_SIZE
capability so it sounds normal. -
