• Download encrypted TS files from video stream

  8 janvier 2021, par albertma789

  Following this post, I usually download transport stream (.ts) files by using the browser's developer console to find the URLs of the .ts files and then I use wget to download them. After that I use the ffmpeg -f concat method to combine them into an mp4 file.

  



  Recently I come across a site that streams videos and I used the same method to download all the .ts files. The site is here. After I downloaded all the individual .ts files, I use ffmprobe to check the file format but realized the .ts files cannot be understood by ffmpeg/ffmprobe. While the site uses http (not https) I thought the streams are not encrypted so I tried to open the .ts file in an hex editor but I don't know what format it is (but they don't look like zip/gz). My question is : are the transport steams encrypted ? If yes, is there a way to decrypt them ? If not ? Can anyone point me to the right direction such that I can make ffmpeg understand them ?

  



  An example transport stream (first & second) are here and here but the link might expire in a bit. In that case you will need to open the site in developer console to find the updated link to the .ts files.

  



  The site uses JW Player 8.0.0

def vidcapt():
    a = time.strftime("%H,%M,%S")
    cap = cv2.VideoCapture(0)
    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    out = cv2.VideoWriter(a+'.avi', fourcc, 24.0, (640,480))
    t1 = time.time()
    while(cap.isOpened()):
            ret, frame = cap.read() 
            if ret == True:
                    out.write(frame)
                    cv2.imshow('frame',frame)
                    t2 = time.time()
                    time_diff = t2-t1
                    if time_diff >= 5:
                            break
            else:
                    break
    cap.release()
    out.release()
    cv2.destroyAllWindows()

while True:
        vidcapt()


clip1 = VideoFileClip("11,05,42.avi")
clip2 = VideoFileClip("11,05,47.avi").subclip(50,60)
final_clip = concatenate_videoclips([clip1,clip2])
final_clip.write_videofile("merged.avi")
