ffmpeg  命令引起的崩溃问题

会写程序的摄影师 2016-08-31 03:19:38
这是我的C代码，在大部分机型上没有什么问题，就是一个ffmpeg修改main方法在android上执行命令。
在乐视手机上会引起native的崩溃，下面是崩溃的log，感觉可能是跟fork进程的代码有什么问题，看有没有人愿意指点一下

用FFmpeg制作WebP动图
之前写过一篇文章，是教大家用FFmpeg制作GIF动画的。今天在讨论到项目中碰到的一个.apng动画素材引起的程序崩溃时，有位同学建议：我们为啥不用WebP来代替.apng？是啊，why not？ 网上搜到一篇文章。自己试了一下，发现强大的FFmpeg果然支持制作WebP动图，于是顺手做了些笔记。 先来试一下这条命令： ffmpeg -ss 25 -t 5 -i D:\Media\bear.wmv -vf scale=240:-1 -r 10 -lossless 1 -loop 0 -y D:\bea
ffmpeg与新合成程序效率对比测试
找到了合成的程序崩溃原因，是new了一个新的数组以后，没有及时的delete，当数据量增大以后，由于循环调用，引起了内存分配不足，从而程序崩溃。 解决方法：代码之前，用到内存拷贝时再new,拷贝完后紧接着delete,这样就解决了问题。 测试了三组视频， 这是周五测试的那次，有所补充和修改，其中Linux码率：200kb/s,  windows 码率4000kb/s, 结果如下：
