I tried using both ffmpeg and handbrake, but apparently swf is compressed and I can't convert them this way. ffmpeg -i input -c:v libx264 -preset ultrafast -qp 0 output.mkv HandBrakeCLI -i source -o destination I know I acn use a tool like xilisoft, but I've more than 3000 videos and would need to run this automatically. Is there a script/ algorithm that can help me automate this process? 回答1: Get gnash: git clone git://git.sv.gnu.org/gnash.git You'll need a bunch of

题意：给定n个数ai(n<=1e6,ai<=1e6)，定义 ，并且fac(l,r)为mul(l,r)的不同质因数的个数，求 思路：可以先用欧拉筛求出1e6以内的所有质数，然后对所有ai判断，如果ai不是质数就利用唯一分解定理计算其所有质因数。然后按照顺序依次计算每个质因子的贡献。假设n=5，对质因子2，依次记录它在数组出现的下标，如果它在2、4下标出现了，那么它的贡献即为所有包含2或4的区间个数，逆向计算，即所有区间个数-不包含2和4的区间个数，即 n(n+1)/2-m1(m1+1)/2-m2(m2+1)/2-m3(m3+1)/2，其中m1=2-1-0=1，m2=3-2=1，m3=5-4=1，即3块不包含2和4的子区间长度。 AC代码： #include<cstdio> #include<cstring> #include<queue> #include<vector> using namespace std; typedef long long LL; const int maxn=1e6+5; int n,a[maxn],cnt,vis[maxn],prime[maxn]; int pre[maxn],vis1[maxn]; LL ans,cs; void Eular(){ for(int i=2;i<maxn;++i){ if(!vis[i]) prime[cnt++]=i;
