How to use custom FFMPEG 6.1 code?

We have a forked version of FFMPEG 6.1 with a couple of custom filters and functionalities. We would like to use that version with KSPlayer and FFMPEGKit. Could you point to what steps do you recommend to take to have that FFMPEG version working in this stack? Thanks in advance.

怎么将lgpl分支删除了，现在默认gpl了吗

这样编译是不是可以支持KSplayer和MPV两套内核

/// build MPV
swift package --disable-sandbox BuildFFmpeg enable-libdav1d enable-openssl enable-libsrt enable-libfreetype enable-libfribidi enable-harfbuzz enable-libass enable-mpv platforms=ios

我想在播放器里面同时支持两套内核，特定情况下使用MPV播放器。这样编译是不是既提供了ksplayer的依赖支持，又引入了mpv。

Compilation fail because hogweed is missing.

Hi,

Trying to build FFmpeg or SMB with a clean homebrew installation, Xcode 15.1 on a M1 pro max cpu using:

swift package --disable-sandbox BuildFFmpeg enable-FFmpeg platforms=macos or swift package --disable-sandbox BuildFFmpeg enable-nettle enable-gnutls enable-libsmbclient platforms=macos

These 2 commands fail because of hogweed:

FFmpeg while configure:

Is it possible to receive and show UDP live stream using FFPlay in Swiftui?

Anyone met this error: Could not resolve host: github.com when executing git clone source code command

@kingslay , stupid question but, when building with swift package BuildFFmpeg I met this error:

I copied the commands and execute them in the terminal, it clones successfully.

Where does the build output go to?

Hi,

I'm building successfully, but my repo is unchanged after that. Where does the build output go to?

smb 协议还是无法使用吗？还是需要额外什么配置吗？

编译过程中报错

编译libsmbclient中途报这个错误，我用的是M1芯片的MacBook

Maybe change meson file

I don't know which version is correct but i'm using an improved version of meson file in my copy.

about libmpv

如何在不播放的情况下,获取视频的总时间长度? 目前貌似没有 api 可以获取?

您好,如何在不播放的情况下,获取视频的总时间长度? 目前貌似没有 api 可以获取?

Version

Hi;)
Can you please provide new lib version, 6.1.1?

ffmpeg升级到6.1后，部分直播无法播放

test url: http://live.aptvapp.com/test.php
降级之后可播放

这个php代理如果加上了： header('Content-Type: application/vnd.apple.mpegurl');
就可以播放了，在6.1之前没问题

请问如何为 xros 编译 libsrt 和 openssl？

我现在能为 xrosSimulator 成功编译 openssl，但是 xros 却始终搞不定，请问大神是如何编译的？感谢感谢

Can't Build

Hi,

It seems this repository change somehow, I can't find the previous issues we've discussed in. Anyway, I can't build. This is an M1 Pro Mac, Xcode 15.0:

➜  swift package --disable-sandbox BuildFFmpeg

error: Unknown subcommand or plugin name ‘BuildFFmpeg’
Usage: swift package <options> <subcommand>
  See 'package -help' for more information.

am I supposed to run this from the root folder? I think I tried all folders.

Compiling doesn't works (error while build libsrt)

Unable to submit app with FFmpeg

Hi,

It seems I'm having an issue submitting my app after updating to the latest build. Any idea?

 [Application Loader Error Output]: ERROR: [ContentDelivery.Uploader] Asset validation failed (90035) Invalid Signature. Code object is not signed at all. The file at path “PlayerX.app/Frameworks/libass.framework/Libass” is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/support/code-signing.

Broken compile on iOS

The following commit breaks compilation for iOS devices when using CocoaPods.

如何支持 nfs?

看到此库已经将编译 nfs 的脚本加进去了。但是不知道 ffmpeg 如何开启 nfs 的支持，就像 libsmbclient 的支持，ffmpeg 文档中并没有看到有 nfs 协议的支持。

为iOS编译失败

系统：macOS 14.0 23A344 arm64

main和mpv分支都试了，使用如下命令进行编译：

swift package --disable-sandbox BuildFFmpeg enable-libdav1d enable-openssl enable-libsrt enable-libfreetype enable-libfribidi enable-harfbuzz enable-libass enable-mpv platforms=ios

失败后查看 .Script/harfbuzz/ios/scratch/arm64.log日志出错信息：

请问是哪里操作有问题吗？

关于编译 FFmpeg 的问题请教

没有研究过这一块，所以有一些问题不明白。

FFmpeg 是一个开源的音视频处理工具集，它用 c 语言写的。

各个平台（Linux/Windows/macOS/tvOS/iOS等）需要编译其源码生成支持对应平台的二进制，以及头文件。这样在项目中就可以通过调用头文件中的函数定义来调用 FFmpeg 里的具体实现。

本项目 FFmpegKit 编写了BuildFFmpeg/main.swift 这个编译规则，它是编译 FFmpeg 的脚本。比如我创建一个 tvOS 平台的项目，项目中引入了 FFmpegKit 这个库，在 Xcode 编译项目的时候，会执行 BuildFFmpeg/main.swift 来进行编译，它会识别编译的平台，如果是 tvOS 则编译出 tvOS，如果是其他平台，则编译出其他平台的产物。

所以上面一段理解有问题吗？是在项目编译时候编译 FFmpeg 么？还是已经编译好了，不用在编译？

如果是在项目编译时候编译 FFmpeg，那使用 swift package manager 导入的 FFmpegKit，哪里的规则让 Xcode 编译项目时候先执行 BuildFFmpeg/main.swift 来进行编译？是 Package.swift 这里么？那如果是用 CocoaPods 导入的 FFmpeg，那对应的编译规则是在那里？我在 podspec 中没有找到。

[Suggestion] Change dependencies to git submodule

@karelrooted has a fork where all dependencies are all git submodules.
I've tried it and it really helps a lot because we can check all latest commits for each dependency and makes it easier to apply/create custom patch.

Another things to make this more generic is to auto apply patches from folders with lib name.

we add patch files to lib folder
the script finds all patch for that lib
sort them by name (so we can use patterns like 0001-patch_name.patch)
git reset and then apply them in order on builder init

swift run BuildFFmpegPlugin enable-libdav1d enable-openssl enable-libsrt

but now I see that it's not correct anymore. Would this be the updated command?

swift package BuildFFmpeg enable-libdav1d enable-openssl enable-libsrt

I am getting an error:

Failure!  Makefile wasn't produced.
Please read INSTALL.md and associated NOTES-* files.  You may also have to
look over your available compiler tool chain or change your configuration.
