请教：Android播放RTSP的错误Error(100,0)
大家好，我需要在Android平台上实现RTSP的播放，使用MediaPlayer进行播放的时候，在很多款手机上都是能够正常播放的，但是在三星I9250上不能播放，错误是Error(100,0)，从日志上看，RTSP的DESCRIBE、SETUP、PLAY命令都成功了，但是这个时候系统发了一个SIGSEGV信号，把播放中断了。
请问如何解决该问题？谢谢！！！

[解决办法]
是类似assert异常,是这句引起的:CHECK_LT(trackIndex, mTracks.size());
根据你的打印,trackIndex和mTracks.size()都为1,所以tarckIndex<mTracks.size()
条件失败而异常
android2.3.4源码是这样的:
size_t trackIndex = 0;
while (trackIndex < mTracks.size()
&& !(val == mTracks.editItemAt(trackIndex).mURL)) {
++trackIndex;
}
CHECK_LT(trackIndex, mTracks.size());
可以源码几乎不可能性出现你出现的情况，不知道你用的 三星I9250系统版本是多少？
三星有没有修改过这里的源码
[解决办法]
4.0的源码：
size_t trackIndex = 0;
while (trackIndex < mTracks.size()
&& !(val == mTracks.editItemAt(trackIndex).mURL)) {
++trackIndex;
}
CHECK_LT(trackIndex, mTracks.size());
看打印trackIndex, mTracks.size()都为1,那就比较奇怪了，看这代码似乎是不可能的，
难道是多线程同步出问题了?
[解决办法]
直接原因是val == mTracks.editItemAt(trackIndex).mURL不相等，导致trackIndex == mTracks.size()了。
最终还是因为网站返回的rtp-info信息中的url是相对地址，所以与mTracks.editItemAt(trackIndex).mURL的绝对地址不相等。
修改下判断条件就可以了。
