我有两个要尝试加载到VideoView
使用中的视频
videoView.setVideoURI(Uri.parse(url));
这两个视频分别为视频1和视频2,它们具有以下规格(使用提取ffmpeg -i
);实际上,它们是同一视频的两种不同编码:
影片1:

我知道Honeycomb附带了AAC支持,因此我用几种设备测试了这些视频。结果如下:
SGS II with custom 4.0.3 OS(Sensation ROM 3.4 with CF-Root kernel) - Video 1:OK - Video2:OK
SGS I with Samsung 2.3.3 OS - Video 1:error (1, -2147483648) - Video 2:OK
SGS I with custom 4.0.3 OS(ICS SGS TEAM ROM with Devil kernel) - Video 1:error (1, -2147483648) - Video 2:OK
Nexus One with original 2.3.6 OS - Video 1:See (1) below - Video 2:See (2) below
Emulator with 2.2 OS - Video 1:error (1, -2147483648) - Video 2:error (1, -2147483648)
Emulator with 4.0.3 OS - Video 1:error (1, -2147483648) - Video 2:error (1, -2147483648)
这两部影片都可以在PC的Google Chrome中正常播放。补充一点,在“确定”的情况下,视频和音频都可以正确播放。在错误(1,-2147483648)的情况下,所有设备(Nexus One除外)都会产生相同的日志:
