视频末尾的关键帧丢失
请问一下作者，是什么原因导致视频后面几秒的帧会丢失，是因为按照张数分割导致最后几秒未达到分割的偏移量导致不再抽帧的缘故吗？试了好3-4分钟不等的视频，都是这样，视频比较短的话，张数比较多的情况下就比较正常
如果我按张数为2去生成，第一张是视频首帧，第二张是视频最后几秒的那帧。
运行环境：win11
emsdk安装正常，编译wasm也正常。
几个个问题请教
感谢大佬，在使用中发现以下几个个问题，还请解疑答惑，感觉
1、info传1的话会报错 [Log] RuntimeError: Division by zero (evaluating '(_captureByCount = Module["_captureByCount"] = Module["asm"]["captureByCount"]).apply(null, arguments)')
2、info传2的话，截取收尾各一张
3、上传23s视频截取10张，按照2s间隔截取的话发现结果中存在近似图（可能时间间隔问题）
4、onChange发现触发超过十次，同一毫秒打印多次
每次截图都会报错，能帮忙分析下这个错误有影响吗
canvas导出base64时可否自定义图片的宽高呢
超级酷的项目，我运行 bash ./script/build.sh 时报错：emcc: command not found
./src/capture.worker.ts 21.3 KiB [built] [code generated]
webpack 5.75.0 compiled successfully in 629 ms
./script/build_wasm.sh: line 16: emcc: command not found
