Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

ffmpeg not creating audio file
13 février 2015, par DriesI’m trying to write raw s16le audio to an audio file using ffmpeg.
This is the command I’m using :ffmpeg -y -f s16le -acodec pcm_s16le -ar 44100 -ac 1 -i - -vn -ar 44100 -ac 1 OUTPUT_FILE.wav
After this command is handled I use stdin to put data in the encoder like this :
fwrite(samples_, sizeof(short int*), numSamples, audioffmpeg);
where
samples_
is ashort int*
with a number ofnumSamples
combined. At the moment I’m trying this per sample (sonumSamples
is 1).For some reason this isn’t creating a new file. Although, when I use a previously created file as input (so I don’t use stdin) it does create a new file.
FFmpeg doesn’t seem to be outputting so I can’t give that

ffmpeg connection reset by peer
8 mars 2015, par Quentin SpottiswoodeI have a problem when using ffmpeg :
quite often my clients will have slightly dodgy internet connections but they subscribe to a service which is designed to record a stream that they are hosting, and record it for hosting on something like a wordpress site.
ffmpeg is called by a python script. I would like, ideally, to know if ffmpeg will throw an exception or return a value that can be accessed by the python script and used as a variable to determine if there was a problem recording the audio.
at the moment python calls ffmpeg using :
os.system('ffmpeg -i [stream address] -t 1:00 -acodec copy ')
when I simulate a connection loss (turning off the NIC on the virtual machine) ffmpeg prints to the terminal

How to extract a video snippet from a video file that is being written in by ffmpeg in realtime
26 février 2015, par alex.bAt the moment i am recording a LIVE stream video from youtube with youtube-dl (https://github.com/rg3/youtube-dl)
The command i use for this :
youtube-dl --id -f 92 https://www.youtube.com/watch?v=VYlQJbsVs48
92 is a format code that i got after executing a command to get the formats, that gave me this list :

95 mp4 720p HLS
96 mp4 1080p HLS (best)This is creating a file called VYlQJbsVs48.mp4.part that gets bigger and bigger of course.
Is there a way to extract a video snippet from that live stream or form the part file ? Or maybe there is a better way of doing this ?
What i have noticed is that if i force quit iTerm2 while youtube-dl is running the .part file it creates wont contain any index information (something to do with an moov atom not being present in the mp4 file - which is the information about the number of frames and other things - metadata i think), so it makes me think i cannot extract from the file.
Maybe if there would be a way that youtube-dl can write the index information at all times or maybe another way that i can record the live stream and get video snippets while its recording.
I forgot to mention i am doing this on OSX Yosemite. I have FFMPEG installed with homebrew and youtoube-dl
I am more than happy to try stuff on UBUNTU if there is a solution.
Any help would be greatly appreciated.
Thank you.
