firewire capture card

We have to confirm that our mobile phone network is not a problem, we can refer to the following methods to solve the OH. The minimum number of passes through the FireWire 　 Minimum configuration Recommended configuration Cpu P4 1.5G P4 2.8 Memory 256

Wireshark cannot capture wireless network card data Solution The capture session cocould not be initiated (failed to set hardware filter to promiscuous mode) always appears ). Solution: wireshark-> capture-> interfaces-> options on your atheros-> capture packets in promisc

This section describes how to program TV cards in Linux. As mentioned at the beginning, video Linux driver, v4l for short. In fact, the video for Linux Two driver is now available. V4l2 solves some problems in v4l and improves hardware performance. However, v4l2 is still not integrated into the Linux kernel. To use v4l2, you only need to download the v4l2 patch. Unless otherwise specified, the content is only applicable to v4l devices. We all know that in Linux, in order to avoid the complexity

expressed as 8 bits. When the grayscale of the image has more precise requirements, it can be represented by 10-bit, 12-bit, etc. Color Image: Color image can be composed of RGB (YUV) 3 colors, according to its brightness level of different 8-8-8,10-10-10 and other formats. (3) Number of transmission channels when a high-resolution image is taken at a higher rate, a high output rate is generated, which generally requires simultaneous output of multiple signals, and the image

In fact, it has been a long time to explore the problem of network card packet capture. I found some basic things in the last few days. I will just repeat them here. Packet Capture first needs to know that the data transmitted through the NIC is actually through the underlying link layer (MAC). in Linux, the data traffic we obtain from the NIC is actually directl

The most recent project used the big Huan DHQP300 video capture card for video surveillance applications, using Java development, no way, and have to re-encapsulate vendors to provide the SDK, just at the beginning of the use of the image is directly displayed on the computer screen, so there will be a problem, Moving the window when the image will not move, obviously this is not possible, and then re-read
