问题 I'm receiving audio via RTP, so I'm opening input from the SDP I generate. Media is coming from Port_sender , IP_sender . IP and port of the server for listening: IP_server , Port_server . Here is my SDP template.

Trouble using ffmpeg in c# how to correctly format string to upscale videos?

由 喜你入骨 提交于 2021-02-11 12:26:36
问题 So I am writing an app in c# to upscale videos to a certain resolution. It uses ffmpeg to do this. What happens is after selecting the video file, and clicking 1080p it creates the directory folder but does not actually write the upscaled video to it. I think I must have a string format issue: private void HD_Click(object sender, EventArgs e) { if (textBox1.Text == null) { MessageBox.Show("You've not selected your video file yet. Please do so before continuing, cheers."); } else { var

Python 批量下载B站视频并打包成软件

一、项目概述 1.项目背景 有一天，我突然想找点事做，想起一直想学但是没有学的C语言，就决定来学一下。可是怎么学呢？看书的话太无聊，报班学呢又快吃土了没钱，不如去B站看看？果然，关键字C语言搜索，出现了很多C语言的讲课视频： B站https://www.bilibili.com/是一个很神奇的地方，简直就是一个无所不有的宝库，几乎可以满足你一切的需求和视觉欲。不管你是想看 动画、番剧 ，还是 游戏、鬼畜 ，亦或 科技和各类教学视频 ，只要你能想到的，基本上都可以在B站找到。对于程序猿或即将成为程序猿的人来说，B站上的编程学习资源是学不完的，可是B站没有提供下载的功能，如果想保存下载在需要的时候看，那就是一个麻烦了。我也遇到了这个问题，于是研究怎么可以实现一键下载视频，最终用 Python 这门神奇的语言实现了。 2.环境配置 这次项目不需要太多的环境配置，最主要的是有 ffmpeg （一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序）并设置环境变量就可以了。ffmpeg主要是用于将下载下来的视频和音频进行合并形成完整的视频。 下载ffmpeg 可点击https://download.csdn.net/download/CUFEECR/12234789或进入官网http://ffmpeg.org/download.html进行下载，并解压到你想保存的目录。

问题 So, I want to create a Powershell or Batch file (whichever works best for the task), that I can paste in a folder and after executing it, will start to use FFmpeg to encode all videos The part that works (in .bat): for %%a in ("*.mkv") do( ffmpeg -i "%%a" -c:v libx265 -c:a copy -x265-params crf=25 "%%a [encoded].mkv" pause) This works, but in some folders, I already have [encoded] files. I'd like for the script to skip these files. I asked in reddit and received the following script: for %%a
