  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • How to Add a Watermark to Http live streaming HLS files

    1er novembre 2017, par Oli

    We have about 2000 movies that are streamed to HLS format. each movie is in a folder with one .m3u8 file and lots of .ts files. is there any way to add our Watermark.png to all these movies without re-encoding to .mp4 files using ffmpeg ?

  • cap.isOpened() : returns false in CentOS for Python 3 and OpenCV 3.1.0

    29 octobre 2017, par Mona Jalal

    So cap from opencv 3 doesn’t work in CentOS. I had no problem in OSX or Windows 7 which I tried initially.
    Here is the example code :

    import cv2
    
cap = cv2.VideoCapture('/home/grad3/jalal/PycharmProjects/hw4_cs58‌​5/Concession_LAN_8‌​‌​00‌​k.mp4',cv2.CAP_FFMPEG)
    

    
if not cap.isOpened():
    
    print('not opened')
    

    
while True:
    
    ret,frame = cap.read()
    

    
    if ret == False:
    
        print('frame empty')
    
        break
    
    cv2.imshow('frame', frame)
    
    if cv2.waitKey(1) == ord('q'):
    
        break

    And I get :

    /usr/local/anaconda3/bin/python /home/grad3/jalal/PycharmProjects/hw4_cs585/test.py
    
not opened
    
frame empty
    

    
Process finished with exit code 0

    I can open the video using ffplay vid_name and also here is the result of https://pastebin.com/YGk2DDCi here https://pastebin.com/HSyHSsEZ (ffmpeg codecs). How should I fix this ?

    I have opencv 3.1.0 and here’s some sys info.

  • Segmenting an audio stream or audio only file

    15 janvier 2013, par Luuk D. Jansen

    There is need for an audio only link for HTTP-live streaming. I now use the segmenter in FFMPEG for the video, and that works great. However, when giving an audio-file the segmenter does not seem to work, just creates one segment.

    The call to FFMPEG for the segmentation is :

    ffmpeg -i data/media/1/2/encoded.mp3 -y -c copy -flags global_header
    -map 0 -f segment -segment_time 10 -segment_list data/media/1/2/fileList.txt -segment_format libmp3lame
    data/media/1/2/segment_%05d.mp3

    I did put as the -segment_format 'libmp3lame' in, but it doesn't seem to make a difference.

    The first step is the encoding, this is the bedbug output :
