  • Convert TS-Stream to MKV with ffmpeg [on hold]

    17 septembre 2018, par night4awk

    I’m using ffmpeg 3.2.7 and I have a problem converting a ts-file lossless to mkv.
    The source file is a dumped IPTV-stream recorded with dumprtp (from dvbstream 0.5).

    ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

    The convertion is successful, but the output file is pixelated every few seconds.

    When I’m converting it with MKVToolnix everything looks fine.

    Does anyone has a solution for that problem ?
    Maybe some option to sync the stream correctly ?

    Here’s a sample output :

    # ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

  • 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.
