合并ts文件
文件在手机中的存储:

├── task.info1) 根据猎豹浏览器中的download.db,使用sqlite3打开文件,查看对应文件在手机浏览器中的真实路径.
2) 通过手机插上U盘/移动硬盘,将文件拷贝到电脑
3) 根据index.m3u8.play中的ts片段文件,生成一个总的ts文件.
可以使用C/OC/python等,读取index.m3u8.play文件,生成类似下面的shell语句,即可合并为一个ts文件.
windows:
copy /b “1.ts”+“2.ts”+…+”n.ts” /y “combine.ts”mac:
cat 1.ts 2.ts > combine.ts相关程序代码:
//读文件
NSString *fullFilePath = @"/xxx/index.m3u8.play";
NSFileHandle *handle = [NSFileHandle fileHandleForReadingAtPath:fullFilePath ];
NSData *data3 = [handle readDataToEndOfFile];
NSString *temp = [[NSString alloc]initWithData:data3 encoding:NSUTF8StringEncoding];
NSArray *tempArray = [temp componentsSeparatedByString:@"\n"];
NSMutableArray *fileMArray = [NSMutableArray array];
for (NSInteger index = 0 ; index < tempArray.count; index++) {
NSString *fileContentLine = tempArray[index];
if ([fileContentLine hasSuffix:@".ts"]) {
[fileMArray addObject:fileContentLine];
}
}
NSString *fileNames = [fileMArray componentsJoinedByString:@" "];
//写入文件
NSString *toPath = @"/yyy/combineTSFile.sh";
NSFileHandle *handle2 = [NSFileHandle fileHandleForWritingAtPath:toPath];
NSLog(@"%s [LINE:%d] fileNames=%@", __func__, __LINE__,fileNames);
NSData *data = [fileNames dataUsingEncoding:NSUTF8StringEncoding];
[handle2 writeData:data];
[handle2 synchronizeFile];
[handle2 closeFile];
4) 将ts文件转换为mp4文件
ffmpeg -i combine.ts -acodec copy -vcodec copy -bsf aac_adtstoasc output.mp4
