The script that I use gets H. mp4 If filter parameters are used in Python script that recursively searches through a user-defined file path and converts all videos of user-specified file types to MP4 with H264 video and AAC audio using However, what comes next will be to decode the bytes into an actual frame image or numpy array (just i frame, p frame, or b frame themselves, not applying delta onto the i frames when it I'm decoding each RTP packet to see if it contains IDR NALU and when it does I pass NALUs (PPS, SPS, I-frame in the case) to decoding pipeline where I run NVIDIA Video Codec SDK Actually, what I'm wondering is if I can decode H264 packets (without RTP header) by avcodec_decode_video2(). The streaming is using raspivid with websocket. I can stream the frames after processing using socket connection. I need to use PyAV to decode H264 raw bytes from webscocket . ; The output format, in case of an MKV video container is format='matroska'. Initialize the lib with something like this: Code: Select all. js. You don't Hello, I want to use NVIDIA HW to get Multiple FHD RTSP streams and to encode processed streams using the same HW. The best thing for you to do is to use a command called ‘MP4Box’. opencv VideoCapture officially doesn't support h264/h265 codec.
