Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

{OpenAL(+FFmpeg)} How to queue variable size buffer due to ogg format ?
11 février 2014, par user3293833(First of all, I may feel sorry about my poor English as it's not my native language.)
I use FFmpeg to decode some audio file and play it with OpenAL by "stream"(i.e."queue" and "unqueue" function of OpenAL).
When I use my program to play .ogg file, I find that it has a variable nb_samples.(due to ogg has variable bit rate ??) There are 128 B, 512 B and 1024 B of nb_samples. As a results, I must call alDeleteBuffers and alGenBuffers before I use alBufferSamplesSOFT(similar to alBufferData) because it would fail to call alBufferSamplesSOFT without recreate the buffer.
Notes : alBufferSamplesSOFT is provided by OpenAL Soft. You can just see it as alBufferData.Nevertheless, I think it's foolish and inefficient if I do this. Is there is some smart method ? I paste the part of code :
while (av_read_frame(...) == 0){
avcodec_decode_audio4(...);
swr_convert(...); // to convert PCM format from FLTP to FLT
alDeleteBuffers(1, theBuffers[?]);
alGenBuffers(1, theBuffers[?]);
alBufferSamplesSOFT(...); // put those data into OpenAL buffer
}if I don't do this, It would failed to update the OpenAL buffer. Is there any method to create a variable size buffer or a big size buffer ? Or is there any method to change the size of buffer ?
Thanks for you guys.
