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" (...) -

avcodec/dca_parser : Extend DTS core sync word and fix existing check
29 avril 2015, par foo86avcodec/dca_parser : Extend DTS core sync word and fix existing check
Check extended sync word for 16-bit LE and BE core streams to reduce
probability of alias sync detection. Previously sync word extension was
checked only for 14-bit streams (and this check did not properly work
across buffer boundary).Use 64-bit parser state to make extended sync word detection work across
buffer boundary.This is sufficient to make the sample in ticket #4492 parse
successfully.Signed-off-by : Michael Niedermayer <michaelni@gmx.at>

using ffmpeg implementation live video/audio
14 mars 2018, par geeeekI am going to implementation live video/audio service using ffmpeg.
I am using embedded board with camera, mic. Receiver is android phone.
as summary :
sender : embedded board.
receiver : android phone.I have an embedded board with a camera and a microphone. The camera’s data is raw h264 data, and the audio data is raw pcm data. I want to do live video communication with Android phone, but I do not know how.
I would like to mux two data with ffmpeg and send it, but I do not know if it is possible. Thank you for your advice.
I can not be sure because I have no experience about ffmpeg in live.
About above enviroment please suggest your best methods.

Convert Audio Files using FFMPEG in android
25 avril 2018, par Venkat MaddyI developing android application, Where I’ve asked to record the calls and convert them to WAVE(.wav) format and send to server.
I am able to successfully record and save the audio in my mobile. The recorded file mime type is 3gpp, now I want to convert this 3gpp file to wav. I tried using FFMPEG but unable to convert it. I am posting my code here, Any help would be grateful.
While Converting the recorded file from aac to wav, I’m getting below error
