问题是一定的转换器（使用不同的设置），将创建一个没有我的三星Galaxy Android设备上运行的视频文件。在code这里是通用的，但我认为codeC已经是这样做的H.264视频转换的时候。然后我下载了大约5视频转换器和2人会真正发挥3GPP，我的设备可以播放。因此，如果任何人有这个问题，我会建议您尝试一堆视频转换器，具有不同的codeC /音频设置。我最终能找到一个在我的具体情况制定

The problem was the certain converters (with different settings) will create a video file that doesn't run on my Samsung Galaxy android device. the code here is generic, but i think the codec has to be something like H.264 when doing the video conversion. I then downloaded about 5 video converters and 2 of them will actually make a 3GPP that my device can play. so if anyone else has this problem, i would recommend trying a bunch of video converters, with different codec/audio settings. i was eventually able to find one that worked in my particular case
