技术背景
实际上,我们在2015年做Android平台RTSP、RTMP播放模块的时候,第一版就支持了多实例播放,因为SDK设计比较灵活,做个简单的player实例封装即可实现多实例播放(Android Unity的就有多路demo),所以官方一直没有正式demo,本次也是有个开发者提到,希望测试下我们多路播放的效果,自己又不想做封装,索性给做个版本。
技术实现
废话不多说,先上图:
我们针对的功能展示,主要是播放和录像这块,先说播放:
/*
* SmartPlayer.java
* Author: https://daniusdk.com
* Created by DaniuLive on 2015/09/26.
*/
class ButtonPlayback1Listener implements View.OnClickListener {
public void onClick(View v) {
if (stream_player_1_.is_playing()) {
Log.i(TAG, "Stop player1..");
boolean iRet = stream_player_1_.StopPlayer();
if (!iRet) {
Log.e(TAG, "Call StopPlayer failed..");
return;
}
stream_player_1_.try_release();
btn_playback1.setText("开始播放1");
SetViewVisibility(surface_view_1_);
} else {
Log.i(TAG, "Start playback stream1++");
int play_buffer = 0;
int is_using_tcp = 0;
if(!stream_player_1_.OpenPlayerHandle(playback_url_1_, play_buffer, is_using_tcp))
return;
stream_player_1_.SetView(surface_view_1_);
boolean is_mute = false;
boolean iPlaybackRet = stream_player_1_.StartPlayer(isHardwareDecoder, is_enable_hardware_render_mode, is_mute);
if (!iPlaybackRet) {
Log.e(TAG, "Call StartPlayer failed..");
return;
}
btn_playback1.setText("停止播放1");
}
}
}
对应的OpenPlayerHandle()实现如下:
/*
* LibPlayerWrapper.java.java
* Author: https://daniusdk.com
*/
public boolean OpenPlayerHandle(String playback_url, int play_buffer, int is_using_tcp) {
if (check_native_handle())
return true;
if(!isValidRtspOrRtmpUrl(playback_url))
return false;
long handle = lib_player_.SmartPlayerOpen(application_context());
if (0==handle) {
Log.e(TAG, "sdk open failed!");
return false;
}
lib_player_.SetSmartPlayerEventCallbackV2(handle, new EventHandleV2());
lib_player_.SmartPlayerSetBuffer(handle, play_buffer);
// set report download speed(默认2秒一次回调 用户可自行调整report间隔)
lib_player_.SmartPlayerSetReportDownloadSpeed(handle, 1, 4);
boolean isFastStartup = true;
lib_player_.SmartPlayerSetFastStartup(handle, isFastStartup ? 1 : 0);
//设置RTSP超时时间
int rtsp_timeout = 10;
lib_player_.SmartPlayerSetRTSPTimeout(handle, rtsp_timeout);
//设置RTSP TCP/UDP模式自动切换
int is_auto_switch_tcp_udp = 1;
lib_player_.SmartPlayerSetRTSPAutoSwitchTcpUdp(handle, is_auto_switch_tcp_udp);
lib_player_.SmartPlayerSaveImageFlag(handle, 1);
// It only used when playback RTSP stream..
lib_player_.SmartPlayerSetRTSPTcpMode(handle, is_using_tcp);
lib_player_.DisableEnhancedRTMP(handle, 0);
lib_player_.SmartPlayerSetUrl(handle, playback_url);
set(handle);
return true;
}
对应的开始播放、停止播放设计:
/*
* LibPlayerWrapper.java
* Author: https://daniusdk.com
*/
public boolean StartPlayer(boolean is_hardware_decoder, boolean is_enable_hardware_render_mode, boolean is_mute) {
if (is_playing()) {
Log.e(TAG, "already playing, native_handle:" + get());
return false;
}
SetPlayerParam(is_hardware_decoder, is_enable_hardware_render_mode, is_mute);
int ret = lib_player_.SmartPlayerStartPlay(get());
if (ret != OK) {
Log.e(TAG, "call StartPlay failed, native_handle:" + get() + ", ret:" + ret);
return false;
}
write_lock_.lock();
try {
this.is_playing_ = true;
} finally {
write_lock_.unlock();
}
Log.i(TAG, "call StartPlayer OK, native_handle:" + get());
return true;
}
public boolean StopPlayer() {
if (!check_native_handle())
return false;
if (!is_playing()) {
Log.w(TAG, "it's not playing, native_handle:" + get());
return false;
}
boolean is_need_call = false;
write_lock_.lock();
try {
if (this.is_playing_) {
this.is_playing_ = false;
is_need_call = true;
}
} finally {
write_lock_.unlock();
}
if (is_need_call)
lib_player_.SmartPlayerStopPlay(get());
return true;
}
录像设计:
/*
* SmartPlayer.java
* Author: https://daniusdk.com
*/
class ButtonRecorder1Listener implements View.OnClickListener {
public void onClick(View v) {
if (stream_player_1_.is_recording()) {
Log.i(TAG, "Stop recorder1..");
boolean iRet = stream_player_1_.StopRecorder();
if (!iRet) {
Log.e(TAG, "Call StopRecorder failed..");
return;
}
stream_player_1_.try_release();
btn_recorder1.setText("开始录像1");
} else {
Log.i(TAG, "Start recorder stream1++");
int play_buffer = 0;
int is_using_tcp = 0;
if(!stream_player_1_.OpenPlayerHandle(playback_url_1_, play_buffer, is_using_tcp))
return;
stream_player_1_.ConfigRecorderParam(recDir, 400, 1, 1, 1);
boolean iRecRet = stream_player_1_.StartRecorder();
if (!iRecRet) {
Log.e(TAG, "Call StartRecorder failed..");
return;
}
btn_recorder1.setText("停止录像1");
}
}
}
录像参数配置选项:
/*
* LibPlayerWrapper.java
* Author: https://daniusdk.com
*/
public boolean ConfigRecorderParam(String rec_dir, int file_max_size, int is_transcode_aac,
int is_record_video, int is_record_audio) {
if(!check_native_handle())
return false;
if (null == rec_dir || rec_dir.isEmpty())
return false;
int ret = lib_player_.SmartPlayerCreateFileDirectory(rec_dir);
if (ret != 0) {
Log.e(TAG, "Create record dir failed, path:" + rec_dir);
return false;
}
if (lib_player_.SmartPlayerSetRecorderDirectory(get(), rec_dir) != 0) {
Log.e(TAG, "Set record dir failed , path:" + rec_dir);
return false;
}
if (lib_player_.SmartPlayerSetRecorderFileMaxSize(get(),file_max_size) != 0) {
Log.e(TAG, "SmartPlayerSetRecorderFileMaxSize failed.");
return false;
}
lib_player_.SmartPlayerSetRecorderAudioTranscodeAAC(get(), is_transcode_aac);
// 更细粒度控制录像的, 一般情况无需调用
lib_player_.SmartPlayerSetRecorderVideo(get(), is_record_video);
lib_player_.SmartPlayerSetRecorderAudio(get(), is_record_audio);
return true;
}
开始录像、结束录像:
/*
* LibPlayerWrapper.java
* Author: https://daniusdk.com
*/
public boolean StartRecorder() {
if (is_recording()) {
Log.e(TAG, "already recording, native_handle:" + get());
return false;
}
int ret = lib_player_.SmartPlayerStartRecorder(get());
if (ret != OK) {
Log.e(TAG, "call SmartPlayerStartRecorder failed, native_handle:" + get() + ", ret:" + ret);
return false;
}
write_lock_.lock();
try {
this.is_recording_ = true;
} finally {
write_lock_.unlock();
}
Log.i(TAG, "call SmartPlayerStartRecorder OK, native_handle:" + get());
return true;
}
public boolean StopRecorder() {
if (!check_native_handle())
return false;
if (!is_recording()) {
Log.w(TAG, "it's not recording, native_handle:" + get());
return false;
}
boolean is_need_call = false;
write_lock_.lock();
try {
if (this.is_recording_) {
this.is_recording_ = false;
is_need_call = true;
}
} finally {
write_lock_.unlock();
}
if (is_need_call)
lib_player_.SmartPlayerStopRecorder(get());
return true;
}
