使用Java搜索最佳视频压缩

[英]searching for best video compressing with java

原文 2015-09-22 23:44:11 3 1 java/ video/ compression/ snappy/ jcodec

I need to greatly reduce the filesize of a large set of jpg images created by a java program. 我需要大大减少由Java程序创建的大量jpg图像的文件大小。 I thought video should be best choice and in particular mp4. 我认为视频应该是最好的选择，尤其是mp4。 but, I don't know why the size of mp4 video with h.264 codec is bigger than the size of the image set in the only implementation I found, so I made my own archive format that is basically the imageset merged together in 1 file and compressed with Snappy , plus the info for split them again. 但是，我不知道为什么带有h.264编解码器的mp4视频的大小比我发现的唯一实现中的图像集大，所以我制作了自己的存档格式，基本上就是将图像集合并为1文件，并使用Snappy压缩，再加上重新分割的信息。 so the question are: 所以问题是：

Does anyone know a good compression video encoder for java? 有人知道Java的压缩视频编码器不错吗？
Does anyone know why in that implementation the file growth and avoid it? 有谁知道为什么在该实现中文件增长并避免它？
currently basing on test I found snappy is reducing size by 15-20%, i know that jpg is already a compressed format and miracles in further compressing can't be done but i'm trying, so if the previous 2 point fail, someone know how minimize the file size in other ways than video? 目前基于测试，我发现snappy正在将尺寸减小15-20％，我知道jpg已经是一种压缩格式，无法进行进一步压缩的奇迹，但是我正在尝试，因此，如果前2点失败，有人知道如何通过视频以外的其他方式最小化文件大小？

EDIT: the jpg single images are already greatly compressed so i don't need a jpg algorithm. 编辑：jpg单个图像已经被大大压缩，所以我不需要jpg算法。

Only have your program record an image if something in the camera changes. 仅当相机中的某些内容发生变化时，程序才记录图像。 This should be fairly easy to code, and will reduce the file size by a ton. 这应该相当容易编码，并且将使文件大小减少一吨。
