than the USB camera, which is a more expensive reason for it.Then there is a question, why take a picture for 7 seconds?Increase the-v parameter to view debug information:raspistill -o image.jpg -rot 80 -vYou can see a line of information inside: Time Delay：5000 . Then look at the command document and find that the default-t parameter equals 5000, which will wait 5 seconds before taking the picture.Then increase the speed of the-t parameter set a little bit faster, it is true, but in the test f

stream.Shut downand finally the release.H264 and AAC data streamsAs mentioned in this paper, rtmp push audio and video streaming package form similar to the FLV format, it can be seen, to the FMS push H264 and AAC live stream, need to first send "AVC sequence header" and "AAC sequence Header", these two data contain important coding information, without them, the decoder will not be decoded.The AVC sequence header is the Avcdecoderconfigurationrecord structure in the standard document "iso-1449
The example in this article will be implemented by reading the PC webcam video data and sending it as a live stream with the RTMP protocol. Example contains the 1, the use of FFmpeg libavdevice 2. The basic flow of video decoding, encoding and pushing has a strong comprehensive. To use Libavdevice related functions, you first need to register the relevant components Avdevice_register_all (); Next we want to list the DShow devices available in the co

Abstract: The Android system is very special. The App needs to undergo simulated testing. Even so, there is still a solution-virtualization technology. Previous simulators, such as those provided by eclipse, were very slow, and the Simulator version was not the latest. Boot can be said to almost force you into a desperate situation, slow to death; load a program, wait for you to come back after the toilet to find that the load is not complete, no matt
The iOS Simulator is a helper tool that can be used when developing a program on the iOS platform under Mac. iOS Simulator is part of the Xcode, Xcode is Apple's own iOS development program that can be downloaded for free!

First, there may be many reasons for this problem, but in most cases it is caused by inconsistent SDK and ADT versions. At the beginning of Android development, ADT Bundle was directly downloaded from Android Developers. Its ADT version is 22.3. Later, the SDK automatically updated to 22.6, but the ADT was not updated, therefore, the above problems occur. Directly update the ADT to solve the problem. The ADT update method is as follows: Http://blog.csdn.net/shengxia0dubing/article/details/213342
The Android system defaults to only a one-way access to the PC via IP (10.0.2.2), and PC computers cannot access the Android emulator system directly via IP. A port redirection (redir) is required to enable communication between PC and Android emulator systems and the Android emulator. First, the Telnet client installation required for Port redirection: Windows: Install the Telnet client. If it is not installed, you can enable Telnet client functionality by locating the Telnet clien
