Optionally, use `apple.sh` to combine bundles created by these three scripts in a single bundle.
|
||||
|
||||
Please note that `FFmpegKit` project repository includes the source code of `FFmpegKit` only. `ios.sh`, `macos.sh` and
|
||||
`tvos.sh` need network connectivity and internet access to `github.com` in order to download the source code of
|
||||
`FFmpeg` and external libraries enabled.
|
||||
|
||||
#### 2.1 Prerequisites
|
||||
|
||||
`ios.sh`/`macos.sh`/`tvos.sh` requires the following packages and tools.
|
||||
|
||||
1. Use your package manager (brew, etc.) to install the following packages.
|
||||
|
||||
```
|
||||
autoconf automake libtool pkg-config curl cmake gcc gperf texinfo yasm nasm bison autogen git wget autopoint meson ninja

||||
```
|
||||
|
||||
2. `ios.sh`/`macos.sh`/`tvos.sh` needs network connectivity and internet access to `github.com` in order to download
|
||||
the source code of all libraries except `ffmpeg-kit`.
|
||||
|
||||
3. Install the tools necessary listed below in `2.1.x`.
|
||||
`ios.sh`, `macos.sh` and `tvos.sh` require the following tools and packages.
