FFmpeg Sample Program Collection-git bulk Fetch script

A series of sample programs on FFmpeg were made, which consisted of the FFmpeg sample program collection, which included the following items:
Simplest ffmpeg player: The simplest ffmpeg-based video player
Simplest ffmpeg audio player: The simplest ffmpeg-based sound player
Simplest ffmpeg pic encoder: The simplest ffmpeg-based image encoder
Simplest ffmpeg Video encoder: The simplest ffmpeg-based codec
Simplest FFmpeg Audio encoder: The simplest ffmpeg based codec
Simplest ffmpeg streamer: The simplest ffmpeg-based ejector (push rtmp)
Simplest FFmpeg mem Handler: The simplest example of memory read and write based on FFmpeg
Simplest ffmpeg device: The simplest ffmpeg-based Avdevice example
Simplest ffmpeg format: The simplest example of a ffmpeg-based encapsulation format
Simplest FFmpeg video filter: The simplest ffmpeg-based Avfilter example (watermark overlay)
Simplest ffmpeg Swscale: The simplest example of ffmpeg-based Libswscale
To facilitate future code upgrades, the code for this project is uniformly uploaded to the git code hosting platform (Sourceforge,github, open source China), and several simple scripts have been made to get the code, as listed below:

Clone (simplest_ffmpeg_demos_git_clone_all.sh): Copy the code from the remote to the native (similar to the download).
Update (simplest_ffmpeg_demos_git_pull_all.sh): Update code from remote to native (similar to upgrade).
Reset (simplest_ffmpeg_demos_git_reset_all.sh): Fallback the native code to the previous version (similar to restore).
Archive (simplest_ffmpeg_demos_git_archive_all.sh): Archive The Native project code (for example, package as Zip).

Of these scripts:

"Github" Https://github.com/leixiaohua1020/leixiaohua1020.github.io/tree/master/batch

Cloning
The clone script can "download from one click" (Clone command) source code to this machine, and set up 3 remote warehouses of the local repository (remotes): Sourceforge,github and open source China.
The script has a originstr parameter that needs to be set. This parameter determines where to clone the source code, and has been tested to find that open source China is significantly faster than SourceForge and GitHub.

Update
The update script can update the source code of the local library to the latest version. As the FFmpeg API changes and bug fixes in some programs, the project's source code needs to be tweaked with the times. You can use the pull command to "upgrade" the source code of the local library to the latest version.
The simplest_ffmpeg_demos_git_pull_all.sh content is shown below.

Reset
The reset script is used to fallback the source code back to the previous version. The Reset command (reset) is used in two situations:
One situation is to change the code when changed to suddenly found that the code compiled, but it is difficult to revert to the original code can be compiled, this time you can use the Reset command;
Another scenario is when you change the code, and then use the Update command (pull) to prompt for an error, and then use the Reset command before using the Update command.

Archive
The archive script is used to package the local code base as a compressed package (*.zip,*.tar.gz). I personally feel that the biggest difference between the Git archive and the direct compression source folder is that the Git archive uses the ". Gitignore" file, ignoring some irrelevant files.
After the script runs, a folder named "Simplest_ffmpeg_demos_list_{Date}" is generated, and the archived file is saved in, and the file is named "simplest_ffmpeg_player_{Date}". Zip ".
