This document is intended for all developers, testers, partners and other interested users using SDK, and requires the readers to have a certain Android programming experience.

Introduction

Baidu AI Cloud Player Android SDK(“SDK”) is the Android platform video player software development kit (SDK) introduced by Baidu AI Cloud to provide simple and convenient development interface to the developers and help them realize media play feature in the Android mobile devices. SDK provides simple and convenient media application development capacity.

• Local all-media format support Breaking the limit of the Android platform on video formats, it supports all mainstream media formats at present (mp4, avi, wmv, flv, mkv, mov, rmvb, etc.).

• Support wide streaming video formats

  Support the files of multiple formats for progressive and stream-like playback: HLS, RTMP, HTTP and Pseudo-Streaming. 

• Powerful Performance

  Low CPU/memory occupancy rate, fast video loading speed. 

• Low threshold and high flexibility to realize play feature

  Provide the calling interface greatly similar to the system player MediaPlayer class, which is easy for the developer to rapidly develop the media play application; provide the interface greatly similar to the system play control VideoView (this part is provided as the source code form, see BDCloudVideoView in demo for details); provide development examples simultaneously. 

• Optimize the live scenarios

  Provide a starter version  SDK dedicated specially to LVB scenarios, and  support  RTMP, HTTP+FLV, HLS  protocol and  H264  and AAC  code. 

• Copyright Protection

  Support the encryption mode of Baidu AI Cloud PlayerBinding and Token; support the offline download and playback of HLS encrypted videos. 

• Complete CPU architecture support

  Full support to armeabi, armeabi-v7a, arm64-v8a, x86, x86_64

Description of part feature

Multi-rate rapid switchover and seamless switchover

Quick switch：Restart the player internally when switching and seek the play position of the last code rate.

Advantages:

• Through precision Seek, the playing position of two code rates can be connected perfectly.
• Fast switchover speed.

Disadvantages:

• Obvious lags of the player.
• Only support HLS switch.

Seamless switching：Internally switch the data source in the player, internally seek to the next code rate position, you can just refresh the decoder.

Advantages:

• The two code-rate playback positions can be perfectly connected through buffer frame loss.
• Seamless switching, without obvious stutter
• Support full format switch.

Disadvantages:

• Relatively slow switchover, which is related to the cache size and video code rate set by the user. The greater the size of the cache is, the slower the switchover is. The smaller the buffering is, the faster the switchover will be, but there is probability to occur lags.
