. In addition, it can return to the Initial state through the stop () method or reset () method. Released: release status (the term "Idle state Idle" in the official documentation). You can call the release () method in the Initial status to enter this status, all resources bound to the MediaRecorder object will be released. Error: indicates the Error status. When an Error occurs, it enters the Initial status through the reset () method. Tip: similar to MediaPlayer, when using MediaRecorder for

Example of headset plugging and audio channel switching for Android underlying development Example of headset plugging and audio channel switching for Android underlying development Because the headset is separated by the headset microphone, the incident should be reported separately. In the Android system layer, the earphone Jack is determined based on the value of/sys/class/switch/h2w/state (in the example of 4.4.4 _ r2, WiredAccessoryManager. java ). You only need to implement a "True or f

Workflow persistence stores certain State information of a workflow to persistent storage, such as SQL databases and files. Once saved to persistent storage, the workflow can be removed from the memory, load as needed. WF persistence service The WF runtime engine provides a series of underlying function libraries for executing and managing workflow lifecycles. The runtime engine architecture is highly scalable. For example, the runtime architecture can host any type of Windows process, rather th

, the video effect. Because what we get here is the data stream. So you need to use a class avasset to do local storage.See how we actually use this stuff:The following diagram depicts the basic processes used by avcapturesession.(1) Instantiate the Avcapturesession (orange part) to bind the input and output source to the avcapturesession.The input source is set to mic:avcapturedevice *mic = [avcapturedevicedefaultdevicewithmediatype:avmediatypeaudio

connecting to a Linux server is now generally a way to connect remotely using SSH. Recently installed a server, found that Telnet is very fast, ping everything is normal, but SSH connection is very slow. After the online information query, there are a few reasons:1, the server sshd will go to DNS to find the hostname of the client IP access, if the DNS is not available or no related records, it will consume a period of time.2, in authentication gssapi-with-m
