Skip the second chapter of the tool Topoedit introduction, direct media playback of the learning.Media play this chapter, introduced a file to play the example, think of the original learning DShow time, the beginning is also a file playback example, but that example is relatively simple, not much code, NND, and this demo completely blind, on a simple file playback on so much code, hey.The first thing about this chapter is that MF widely uses COM tech

and mobile terminals.Based on the decoding process in the FFMPEG open source code, this paper proposes a design scheme of the streaming media player on the mobile terminal based on the layered architecture. This design features differences in media stream processing when decoding different types of files at the underlying layer, and provides control functions fo

Analysis:
Check the code location. This exception occurs when the mediaprovider server responds to query_transaction, because the memory address that parcel points to is null.

The internal playback engine once called the Oncompletion.oncompletion () callback method, indicating that the MediaPlayer object entered the playbackcompleted state. 9.3) when in playbackcompleted state, you can call the start () method again to let the MediaPlayer object enter the started state again.

The following figure shows the system.Mediascannerpolicer will be in any action_boot_completed,Start when action_media_mounted or action_media_scanner_scan_file intent (intent) is sent. Because parsing the metadata of a media file may take a long time, mediascannerpolicer starts mediascannerservice.
Mediascannerservice calls a public class mediascanner to handle real work. Mediascannerreceiver maintains two types of scan directories: one is the intern

The second is a conversion matrix, which converts the magnetic field data to the actual gravity coordinate. Generally, it can be set to null by default.
The third is an array of 3, indicating that the data obtained from the accelerometer is in onSensorChanged.
The fourth is an array of 3, indicating that the data obtained from the magnetic sensor is in onSensorChanged.
Well, the basic logic is like this.

program is determined by an external event. It is characterized by the inclusion of an event loop that uses a callback mechanism to trigger the corresponding processing when an external event occurs. Two other common programming paradigms are (single-threaded) synchronization and multithreaded programming.8.
