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. -

ffmpeg audio and the iphone
17 juin 2019, par michellehas anyone been able to make ffmpeg work with audio queues, I get an error when I try to create the queue.
ret = avcodec_open(enc, codec);
if (ret < 0) {
NSLog(@"Error: Could not open video decoder: %d", ret);
av_close_input_file(avfContext);
return;
}
if (audio_index >= 0) {
AudioStreamBasicDescription
audioFormat;
audioFormat.mFormatID = -1;
audioFormat.mSampleRate =
avfContext->streams[audio_index]->codec->sample_rate;
audioFormat.mFormatFlags = 0;
switch (avfContext->streams[audio_index]->codec->codec_id)
{
case CODEC_ID_MP3:
audioFormat.mFormatID = kAudioFormatMPEGLayer3;
break;
case CODEC_ID_AAC:
audioFormat.mFormatID = kAudioFormatMPEG4AAC;
audioFormat.mFormatFlags = kMPEG4Object_AAC_Main;
break;
case CODEC_ID_AC3:
audioFormat.mFormatID = kAudioFormatAC3;
break;
default:
break;
}
if (audioFormat.mFormatID != -1) {
audioFormat.mBytesPerPacket = 0;
audioFormat.mFramesPerPacket =
avfContext->streams[audio_index]->codec->frame_size;
audioFormat.mBytesPerFrame = 0;
audioFormat.mChannelsPerFrame = avfContext->streams[audio_index]->codec->channels;
audioFormat.mBitsPerChannel = 0;
if (ret = AudioQueueNewOutput(&audioFormat, audioQueueOutputCallback, self, NULL, NULL, 0, &audioQueue)) {
NSLog(@"Error creating audio output queue: %d", ret);
}The issues only with the audio,
Video is perfect if only I can figure out how to get audio queues to work.

I though of remoteio but there is’nt much doc on that.
I will share the code for the complete class with anyone that helps me get it to work.
The idea is to have a single view controller that plays any streaming video passed to it, similar to ffplay on the iphone but without the sdl overhead.

Truly live streaming to Android/iPhone
4 juillet 2012, par TsaukpaetraI have spent quite a while (past week) trying this to little avail. However, what I want seems completely unheard of. So far, I have reviewed recommendations available through google, which include encoding a static file into multiple static files in different formats, creating a playlist that hosts static files in an m3u8 file (files which get added to the playlist as streaming continues).
I have also seen ideas involving rtmp, rtsp etc which are completely out of the question because of their incompatibility.
Ideally, I would have one webpage that would link to the stream (http://server/video.mp4) and/or show it in a webpage (via the video tag). With that in mind, the most likely format would be h264+aac in mp4 container.Unfortunately, (and probably because the file has no duration metadata) it does not work. I can use a desktop player (such as VLC) to open the stream and play it, but my iPhone and Android both give their respective "Can't be played" messages.
I don't think the problem is caused by the devices' ability to stream, for I have made a streaming shoutcast server work just fine (mp3 only).
Currently, the closest I have become is using the following setup on my win32 machine :
FFMPEG Command: : ffmpeg -f dshow -i video="Logitech Webcam 200":audio="Microphone (Webcam 200)" -b:v 180k -bt 240k -vcodec libx264 -tune zerolatency -profile:v baseline -preset ultrafast -r 10 -strict -2 -acodec aac -ac 2 -ar 48000 -ab 32k -f flv "udp ://127.0.0.1:1234"
VLC: : Stream from udp ://127.0.0.1:1234 to http:// :8080/video.mp4 (No Transcoding), basically just to convert the UDP stream into an http-accessible stream.
Any hints or suggestions would be warmly welcomed !
