转换H.264 AVI容器有关ffmpeg的MP4(convert h.264 avi contai

我想我的H.264 AVI容器转换成MP4容器的ffmpeg。 我发现这工作：

./ffmpeg -i myfile.avi -vcodec copy myfile.mp4

这将生成一个文件，我可以用HTML5视频播放器中播放，但对于传统浏览器我想使用Flash播放器（的Flowplayer）。 该文件不具有的Flowplayer玩，其实它会导致它崩溃。

但是，如果我使用：

这个伟大的工程。 但时间是完全不同的不提CPU周期。 第一个命令是在毫秒测量，而第二可能需要相当长的时间（〜5-40secs）。

有另一种方式我可以很快的AVI转换为MP4容器？ 理想的情况下通过重新多路复用，而不是再编码。

编辑

我使用这个，现在我觉得这是最快的重新编码。 但我又不想这样做。 我只是想重新混流的代码。

ffmpeg -loglevel quiet -i myfile.avi -vcodec libx264 -profile:v baseline -preset ultrafast myfile.mp4

Answer 1:

我不会做不同的比你已经做了。 我试图REMUX在OS X 10.7的有关ffmpeg-1.2的文件：

ffmpeg --info

我想你的命令，并明确

ffmpeg -i myfile.avi -vcodec copy -acodec copy out.mp4

但是，我总是得到以下错误：

所以我做了错误编号的快速调研，发现了pcm_s16le不兼容MP4。 看到这个关于ffmpeg的跟踪bug报告 。

这可能与两者你的命令的解释不同的结果 - 虽然它的奇怪的是，它并没有屈服在你的情况下，错误（旧的ffmpeg快照？）。

所以我猜这个解决方案可能/是从一开始就提供了不同的音频编解码器或音轨转换成不同的编解码器。 作为一个快速测试我的尝试：

ffmpeg -i myfile.avi -vcodec copy -acodec mp2 out.mp4

输出文件被立即写入磁盘 - 没有任何错误都产生。 不幸的是，我没有验证功能的Flash Player结果的可能性。
