FFMpeg Android Stagefright SIGSEGV 错误（h264 解码）

我需要在 Android 2.3+ 上将 h264 文件解码为 YUV。据我了解，我需要与 Stagefright 进行通信，因为在使用 OpenMAX IL 实现关闭访问权限后，这是现在唯一的方法。我已经使用 FFmpeg 0.10（并尝试了 0.9/0.9.1..）来解决此问题，并使用 NDK7 进行编译（并尝试了 NDK6b，得到了相同的结果）：

因此，输入下一个命令会出现 480p 错误： ffmpeg -i /sdcard/视频/480p.mp4

已停止（信号）ffmpeg -i /sdcard/Video/480p.mp4

Android开发人员，有谁知道这个错误意味着什么以及如何处理它？我尝试将 DSP 窗口变大，但没有成功。像“stagefright /sdcard/Video/480p.mp4”这样的命令工作正常。

PS 此外，我发现在一些更大的文件（720p）上，Android 的回答如下：

[libstagefright_h264 @ 0xd479b0]解码失败：80000000

原文

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:
