这几天发了神经又想来搞Android了,实在不知道该做什么,所以就从播放器入手,着手开始把EasyPlayer的代码移植到Android下,到目前为止的确有这么一个版本出来了,但这个版本未做任何优化,无论是ffmpeg解码的汇编指令,也未使用NEON指令,解码后的播放都是由JNI callback到Java来实现的,因此其效率之差可想而知,不过,用老婆的手机(Sumsung 9001)播放QVGA的音视频还算流畅,这起码也算是点安慰,下一步将先把音视频播放部分搞一搞。
先把这个版本放上来。

Both ZTE T800 and HUAWEI TEx0 claim to have T.140 supported, but when I digging into these entities by running some tests between T800, TE40 and TE60, my current status is I’m not persuaded. Maybe only because I don’t know how to configure them to make T.140 enabled. Here is some T.140 related information, and my steps to analysis to the protocols of HUAWEI TEx0 and ZTE T800.

Hi,Jacky,I am confused about how to coomplie FFMPEG for Android, can you lend me a hand?
Hi Leslie,
There are so manny posts discribing how to compile FFMPEG for Android on the internet, I’m not sure what is the exact problem you are encounting with. Can you be more specific?
BTW: if you know Chinese, you can refer to an old post I wrote years earlier. http://bbs.rosoo.net/thread-9394-1-1.html
