  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang 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.

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Audio is lost on transcoding from DTS to AAC

    18 octobre 2015, par cirko

    On a Synology drive, I’m trying to transcode audio in an .MKV file from DTS to AAC using the native ffmpeg encoder. But without any error message (at least I don’t recognize any here), the audio stream is just missing in the output files. I tried it on several different files, all with the same result, leading to the conclusion that either I’m unable to see the error or something’s wrong with FFMPEG. I used the standard FFMPEG package provided with OPKG.
    This is the output I usually get :

    CirkosDaten> ffmpeg -i encodertest.mkv -map 0 -c:v copy -c:s copy -c:a aac 
    
-strict experimental output.mkv

    When I additionally set the bitrate, the output says

    Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 
    
(output.mkv) has not been used for any stream. The most likely reason is 
    
either wrong type (e.g. a video option with no video streams) or that it is 
    
a private option of some encoder which was not actually used for any stream.

    This indicates that somehow the 5.1, 48kHz DTS stream isn’t considered as an input. Why ?

    EDIT : Is it possible that DTS decoding is turned off somewhere here ? I reckoned maybe that’s why I get no errors. But I didn’t see any obvious option for that in the output.

  • Remove Unwanted Rotation of video when merge audio With Video Using FFMPEG

    2 octobre 2015, par bhavesh kaila

    Actually I want to overwrite Audio Using Recorder Audio file into Recorded Video File.For That I am Using FFMPEG Library Project from this Link

    Issue :
    When I capture video in Portrait mode and then merge video with recorded audio merging is working fine but the problem is Video is rotate 90 Degree and then merging is work.I don’t Want to rotate video I want to do merge Only.

    if I capture video in Landscape Mode Then Merging audio is Working Fine.

    Below Currently FFMPEG Command is Used for merging Audio with Video File

    ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0 OutputFile.mp4

    And I Have Tried Using Below Commands also but it’s Not working

    ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 rotate=0 OutputFile.mp4

    And

    ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 translate=1 OutputFile.mp4

    And I have Trying othe possibility also but its not work for me.

    Any Help Would be Acceptable.

    Thanks In Advance

  • How to stop os.system() in Python ?

    30 septembre 2015, par 吴雨羲

    I want to stop the cmd command after 12 seconds. How to stop it ? My program doesn’t work.

    import multiprocessing
    
import os
    
import time
    

    

    
def process():
    
    os.system('ffmpeg -i rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp -c copy dump.mp4')
    

    

    
def stop():
    
    time.sleep(12)
    

    

    
if __name__ == '__main__':
    
    p = multiprocessing.Process(target=process, args=())
    
    s = multiprocessing.Process(target=stop, args=())
    
    p.start()
    
    s.start()
    
    s.join()
    
    p.terminate()

    I change my program follow Pedro’s suggusetion @Pedro Lobito ,but it still doesn`t work.

    import shlex
    

    
import subprocess
    
import time
    

    
command_line = 'ffmpeg -i rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp -c copy dump.mp4'
    

    
proc = subprocess.Popen(shlex.split(command_line), shell=True)
    
print '1' * 50
    
time.sleep(2)  # <-- sleep for 12''
    
print '2' * 50
    
proc.terminate()  # <-- terminate the process
    
print '3' * 50

    And the result in CMD is
