FFmpeg的的Android Stagefright SIGSEGV错误（H264德code） [英] FFMpeg Android Stagefright SIGSEGV error (h264 decode)
问题描述
我需要去code H264 文件为 YUV 在Android 2.3+。据我了解，我需要与Stagefright沟通，因为它了唯一的出路，现在，关闭与访问的的OpenMAX IL 的实施之后。我已经使用FFmpeg的0.10（并试图0.9 / 0.9.1 ..）针对此问题，与NDK7编译它（也试过NDK6b具有相同的结果）：

所以，在进入下一个命令给我的错误与480P： 的ffmpeg -i /sdcard/Video/480p.mp4
停止（信号）的ffmpeg -i /sdcard/Video/480p.mp4

Android的开发者，有谁知道这个错误的手段，以及如何处理呢？ 我试图使DSP窗口更大，但没有运气。 像stagefright /sdcard/Video/480p.mp4命令工作正常。
P.S。此外，我发现，在一些较大的文件（720p）的Android的下一个答案：
[libstagefright_h264 @ 0xd479b0]德code失败：80000000
您启用libstagefright-H264在你的ffmpeg的配置标志，但没有启用它作为一个去codeR这样：
- 让德codeR = libstagefright_h264
I need to decode h264 file to YUV on Android 2.3+. As I understand I need to communicate with Stagefright, as it`s the only way now, after closing access with OpenMAX IL implementations. I have used FFmpeg 0.10 (and tried 0.9/0.9.1..) for this issue, compiled it with NDK7 (and also tried NDK6b with the same result):

So, entering next command give me error with 480p: ffmpeg -i /sdcard/Video/480p.mp4
Stopped (signal) ffmpeg -i /sdcard/Video/480p.mp4

Android-developers, does anybody know what this error means and how to deal with it? I tried to make DSP window bigger, but with no luck. Commands like "stagefright /sdcard/Video/480p.mp4" works fine.
P.S. Additionally I found that on some bigger files (720p) Android answers next:
[libstagefright_h264 @ 0xd479b0] Decode failed: 80000000
You enabled libstagefright-h264 in your ffmpeg configure flags but didn't enable it as a decoder as such:
--enable-decoder=libstagefright_h264
