First, clarify several basic concepts about video. A video file is composed of video streams and audio streams. It is packaged together. This involves three formats: video format, audio format, and package file format. Common File packaging formats include. MP4,. Avi,. mov, And. 3GP. The packaging format is not equal to the video format. Therefore, you cannot know the audio and video formats. Common video formats include: H.264, MPEG-4 v

divided into messaging and standardMessaging is a MMS Message in 3GP format. The standard format is WMV.NOTE: If defaultfilename is not specified, whether videotypes is set to messaging or standard, the stored files are still in WMV format.If defaultfilename is not specified, the system automatically increments the file starting with 001. The image is taken as IMG *** and the video is ***.In the Registry's HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \

1) socket-based, suitable for simple video monitoring solutions. The server compresses the image, and the mobile phone uses the socket to read the data and decode the display. It is best to use Java for the network and ndk for decoding. 2) based on RTSP/RTP. Suitable for the adaptation of existing RTSP Streaming Media Servers. Android supports RTSP Streaming Media, but only supports RTP over UDP (there is also a saying that RTP over UDP is given priority, and RTP over TCP is attempted only afte

your peanut shell account to the "Dynamic DNS" of the router so that you can use a second-level domain name like lius1984.gicp.net.

(If there is audio data, it will be intertwined with the video data, but our goal is to encode the video stream in real time and do not need to process the audio, therefore, when initializing mediarecorder, I do not want mediarecorder. setaudiosource, so there is no audio data .) 3. Complete the capture. Mediarecorder should return to the file header to fill the file header. However, becaus

Now many friends of mobile phone support video to watch movies, but most mobile phones only support 3GP format, and if the software conversion, RM can not support the conversion to 3GP format, you must first convert to AVI or MPEG format to convert to 3GP files. Here, I'd like to show you how to convert RM format to AVI or MPEG. RM Conversion Wizard is a good v
