Lesson three the hardware operation example of recording The following is mainly about the hardware use and operation of recording: 1. Handling the recording environment, to ensure quiet and sound insulation (preferably to do the sound absorption processing, but the amateur conditions are not good, this is a bit difficult, I can not do, hehe). 2. Fixed the mic

Starting from anychat r4086, anychat supports audio synthesis and stereo recording and adds the recording mark constant: VaR brac_record_flags_stereo = 0x00000200; // Copy code The call code is: VaR flags = brac_record_flags_video + brac_record_flags_audio + brac_record_flags_mixaudio + brac_record_flags_mixvideo + brac_record_flags_

() Mediarecorder instance. To start audio capture, call MediaRecorder.start() . To stop audio capture, call MediaRecorder.stop() . When you do with the Mediarecorder instance, call on MediaRecorder.release() it. Calling is always recommended to free the MediaRecorder.release() resource immediately. Call release is always the recommended way to release resources immediately Example:record

Cause analysis of "S-for-machine assistant cannot be enabled during audio recording"The microphone and speaker are used when the S-machine assistant connects to the device. Therefore, when the microphone is in use or other peripheral devices (such as headphones or Bluetooth headsets) are connected, it cannot run.SolutionStops other applications from using microphones and speakers.Well, the above i

This article corresponds to the opening link of the previous "C ++ playing audio stream (PCM bare stream)". It describes how to use C ++ to implement the recording function. Similarly, you can directly create a win32 console program and copy the code to a file name to use it. You can also download the project you uploaded. This project was written in VS2013, if it is a lower version, it will be okay. Click

Added a frame image for Automatically Obtaining streaming media files and automatically generating images. The significance of this function is For example, if someone wants to see a movie, but does not want to take a long time to download the whole movie or clip. Therefore, the video is automatically captured.A picture is equivalent to a poster and an overview. Without a doubt, it takes much longer to download a picture than to download a movie clip! After seeing the "poster", the user de

REALPLAYER11 supports playback in a variety of online media videos, including flash, FLV format or MOV format, and so on, and can record video during playback. Also joined the online video's one-click Download function to the browser, support IE and Firefox, so you can download YouTube, MSN, Google video and so on online videos to the local hard drive to watch offline. RealPlayer11 can record any audio and video in playback to the Media Library. Can

Compared with mediarecorder, The audiorecord class is closer to the underlying layer and has fewer encapsulated methods. However, the audio recording program that implements an audiorecord is also very Simple. The sample code is as follows: It is a pity that there is a problem in this instance testing. During recording, there will be buffer over. Cache leakage t
