2014-01-16 05:38:08 -0600 | asked a question | h264 frame to numpy array Hello, I am new to opencv. using opecv-python. I have created a rstp client in python that receives a h264 stream retunrns single h264 raw frames as a binary string . I am trying to process each frame on-the-fly. I have unsuccessfully tried sever ways to convert this frame into a numpy array for processing. So far I only know that cv2.VideoCapture only accepts a file name, not a frame neither a StringIO object (file like pointer to a buffer). I have also tried something like: nparr = np.fromstring(frame_bin_strg, np.uint8) img_np = cv2.imdecode(nparr, cv2.CV_LOAD_IMAGE_COLOR) but also miserably failed. after many other failed attempts , I ran out of ideas. To summarize what I need to do: I have a h264 raw frame in a variable and I need to create an openvc valid numpy array or a somehow end up with a VideoCapture object containing that single frame, so I can process the frame. Any pointers would be much appreciated. Hope this all makes sense. Thank you in advance |
