该场景下，开启音乐，录屏时选择录制设备音频时，导致了audioserver died；

■ 下一步

找为什么该场景会导致audioserver重启。

Hi all,

该音乐播放器通过MediaPlayer播放的音乐，发生异常的原因是在创建AudioTrack的时候AudioFormat不对，导致空指针。正确的format为0x1错误的format为0x100000.

04-16 01:36:28.725 9814 9877 D AF::TrackHandle: OpPlayAudio: not muting track:67 usage:0 for service UID 1041
04-16 01:36:28.725 9814 9877 W AudioFlinger: isTrackAllowed_l: invalid format: 0x1000000
04-16 01:36:28.725 9814 9877 E AF::Track: Track(67): no more tracks available

下一步:找到AudioFormat设置的位置，确定设置错误的原因。

Hi all,

由于音源数据解析出来后，符合compress offload的播放模式，当采用该播放模式的时候，audio_format会采用从音源里解析出来的audio_format 0x1000000u。而0x1000000u在安卓原生里没有定义，在录屏时会检查audio_format，匹配不上就会导致空指针，进而导致AudioServer die。

目前的解决方法：先把compress offload播放方式禁用，禁用之后，播放音乐和屏幕录制均正常。（禁用之后，理论上只会影响到功耗）
提交如下，正在编译验证：

next：提qcom case询问是否有更好的解决方式
