proc = subprocess.Popen(command, stderr=subprocess.PIPE, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
out, err = proc.communicate()


print(err)

while True:
    ret, frame = cap.read()
    # _, buf = cv2.imencode('.jpg', frame)
    # img_byte = io.BytesIO(buf.tobytes())
    try: 
        proc.stdin.write(frame.tostring())
        print("SENDED")
    except IOError as e:
        print(e) 
        proc.stdin.close()

• Getting "Error while decoding stream #0:0 : Invalid data found when processing input" when using ffmpeg to convert tga to mp4

  22 juin 2020, par Calvin Godfrey

  I've used ffmpeg to convert a bunch of tga files into an mp4 just fine for a few weeks, but it broke for no apparent reason earlier today. I have a pastebin with -loglevel debug here, but the command I use is the same as the one that has worked before — ffmpeg -framerate 60 -i triangle%03d.tga output.mp4, and now it's broken.

  


  The tga files are manually created by a C program that I wrote, but I don't think it's a problem with the file header/format because it hasn't been a problem with ffmpeg before before and I can open the tga files fine with eog and a tga viewer on Windows. Just in case it matters, here's the start of a hexdump for one of the files :

  Would appreciate any help on fixing the ffmpeg (or alternative ways to convert tga to mp4).
