trying to make OpenCV 3.2.0 work with virtualenv
24 juillet 2017, par lollercoasterI’m on Ubuntu 16.04 with Python 2.7 and virtualenv & virtualenvwrapper.
By following this guide I managed to get the following script working with my system Python2.7 which has
cv2globally installed.I used this script to install it :
######################################
# INSTALL OPENCV ON UBUNTU OR DEBIAN #
######################################
# | THIS SCRIPT IS TESTED CORRECTLY ON |

# 4. EXECUTE SOME OPENCV EXAMPLES AND COMPILE A DEMONSTRATION
# To complete this step, please visit 'http://milq.github.io/install-opencv-ubuntu-debian'.The following script below works great with that system-wide installation :
import cv2
img = cv2.imread('some_img.jpg')Though this one doesn’t - even the system Python can’t read videos for some reason...
import cv2
video_capture = cv2.VideoCapture(0)
ret, frame = video_capture.read()
print ret # always Falsebut I want it to work with my virtualenv. So I recompiled OpenCV with :
cmake -D WITH_QT=ON \

</dynamic>Unfortunately, while this works and I can import
cv2in the shell, it cannot read video using the above script, probably due to incorrect compilation or linking offfmpeg? The confusing part is the system-wide installation of OpenCV works fine, even without ffmpeg installed !What am I doing wrong ? How can I get OpenCV working with a virtualenv ?
====
EDIT : Running the C++ video writing example has this result :
$ cd /home/me/code/myproject/OpenCV-3.2.0/build/bin
$ ./cpp-tutorial-video-write ../../samples/data/vtest.avi R Y
------------------------------------------------------------------------------
This program shows how to write video files.
You can extract the R or G or B color channel of the input video.
Usage:
./video-write [ R | G | B] [Y | N]

FFmpeg - Concatenating videos with different resolutions
7 août 2017, par JillI currently have an android app where the videos get combined using ffmpeg’s concat. That works fine. However, when I add text (using drawtext) to one of the videos, after combining the videos again, the combined video gets distorted. The video with the drawtext shows up fine, but then the videos without text switches orientation.
I think the problem roots from the fact that a vertical video on my android phone has the resolution of 1920x1080, however if I use that for the scale when executing drawtext, it becomes horizontal.
I think an example might help explain this better. Let’s say I have 2 vertically recorded videos, and I combine them with concat. The combined video shows up fine. Then if I add text to the 1st video using drawtext, the combined video will then show the first video (with text) at normal orientation (vertical). However, when it transitions to the next video, it first stalls for a couple seconds and then the 2nd video is shown at a horizontal orientation.
Also, I tried this also with having the aspect ratio as 1:1 so it wouldn’t matter, but the second video’s orientation still changed counter clockwise.
Thanks for the help, and happy to add more clarification if needed.
This is for adding the text :
ffmpeg -i input.mp4 -vf drawbox=y=ih-200:color=black@0.5:width=iw:height=200:t=max

ffmpeg how to encode first then use it for another output
10 août 2017, par mahdi ghI’m trying to capture screen with gdigrab and combine int with a sound and then send it on my decklink sdi device.
here is my code to capture :
ffmpeg -framerate 25 -thread_queue_size 512 -f gdigrab -i title="Play" -f dshow -i audio="CABLE Output (VB-Audio Virtual Cable)" -af aresample=resampler=soxr -ar 48000 -acodec pcm_s16le -ac 2 -c:v libx264 -qp 0 -preset ultrafast "output.avi"here is my code for output to ffmpeg :
ffmpeg -i output.avi -f decklink -pix_fmt uyvy422 "DeckLink SDI (2)"this way it works, but when I combine these two arguments to send the output to decklink card on the fly, ffmpeg stops working. here is the combination code :
ffmpeg -framerate 25 -thread_queue_size 512 -f gdigrab -i title="Play" -f dshow -i audio="CABLE Output (VB-Audio Virtual Cable)" -af aresample=resampler=soxr -ar 48000 -acodec pcm_s16le -ac 2 -f decklink -pix_fmt uyvy422 "DeckLink SDI (2)"I have tried so many different combinations but no luck. it works only if i store it on a file then use that file as input. Is there a way to tell ffmpeg to use the result of first command as input of second command ?
Thanks
