cvlc 无法播放 rtsp（omxplayer 可以）
cvlc cannot play rtsp (omxplayer instead can)
收到大华语音串流link：可以用omxplayer，但是vlc 不能播放：
rtsp://user:pass@ipadd:554/cam/realmonitor/channel=1&subtype=1
这是 vlc 的输出：

主要问题是 omxplayer 已被弃用，但在加载 10 秒后播放效果很好。
有人可以让我明白为什么 vlc 根本没有吗？
Debian 中为 live555 提供支持的库在今年 2 月被删除，这影响了所有下游发行版，包括但不限于 RPi OS 和 Ubuntu:
https://askubuntu.com/a/1363113
2 个活动版本是 2020.01.19-1 和 2018.11.26-1.1，Live555 此后已将 GPL 许可证 header 添加到有问题的文件中，但 RFC 问题仍然存在。
现在您可能只想下载最新的 Live555 源代码并编译它……它不起作用。 VLC 引用的函数名称和结构发生了变化，因此 VLC 不会针对源代码进行编译。您需要获取旧版本，我专门使用了这个版本，它是 2020 年的调整快照，发生在 mod阻止 VLC 编译的通知之前：
https://github.com/rgaufman/live555
你想要的配置是./genMakefiles linux-with-shared-libraries，我不知道是否需要，但由于我的系统是x86-64位，所以我先在编译器选项中添加了-m64
编译安装后，我继续编译VLC，将根Live555文件夹放入VLC extras文件夹后添加'--enable-live555'和'--with-live555-tree=extras/live555-master'，但是VLC编译失败，结果Live555 的 make install 不会将所有需要的 header 文件复制到 VLC 所在的位置。它们作为 4 个子文件夹放入 /usr/local/include/，实际的库放入 /usr/local/lib/。添加正确的 CXX/CPP 标志将使它看起来像放置它们的位置，但是我将它们全部放在一个文件夹中并使用了 1 个标志。
我还必须 '--disable-mod' 解决我没有兴趣修复的依赖版本问题，因为我不使用 modplug 或任何 mod 文件。
50分钟后...VLC编译成功！然而，它期望 Live555 的库位于 /usr/lib/ 而不是 /usr/local/lib/，因为编译花费了很长时间，我很好地将库链接或复制到预期的文件夹中，然后VLC 在链接到新文件时与 RTSP 一起工作。或者，如果您需要加载相机源，您可以选择保留原始 VLC 和 运行 直接新文件。
我有同样的问题，vlc 不支持 rtsp。我找到了两个解决方案。
1 - 使用 snap 版本
sudo snap install vlc => rtsp 正在运行。
/snap/bin/vlc rtsp://...
2 - 重建 vlc。我用这个教程来帮助我：https://wiki.videolan.org/UnixCompile/
我在 ./configure 上遇到了一些问题，所以我安装了一些非强制性的包..但我不知道是哪一个..所以我列出了我在测试期间安装的所有包。
sudo apt-get build-dep vlc vlc-plugin-qt phonon4qt5-backend-vlc
sudo apt-get install libqscintilla2-qt5-dev libqt5charts5-dev qtdeclarative5-dev libqt5gstreamer-dev libqt5opengl5-dev phonon4qt5-backend-vlc libqt53dcore5 qtquickcontrols2-5-dev
git clone git://git.videolan.org/vlc.git
cd vlc
./bootstrap
cd contrib
mkdir native
cd native
../bootstrap
make (stop with error : protoc system version 3.12.4 and required version 3.1.0 do not match)
cd ../../
./configure --prefix=/usr/local --enable-merge-ffmpeg --enable-live555
make
现在我有了一个支持 rtsp 的 vlc。
收到大华语音串流link：可以用omxplayer，但是vlc 不能播放：
rtsp://user:pass@ipadd:554/cam/realmonitor/channel=1&subtype=1
这是 vlc 的输出：

主要问题是 omxplayer 已被弃用，但在加载 10 秒后播放效果很好。 有人可以让我明白为什么 vlc 根本没有吗？
Debian 中为 live555 提供支持的库在今年 2 月被删除，这影响了所有下游发行版，包括但不限于 RPi OS 和 Ubuntu:
https://askubuntu.com/a/1363113
2 个活动版本是 2020.01.19-1 和 2018.11.26-1.1，Live555 此后已将 GPL 许可证 header 添加到有问题的文件中，但 RFC 问题仍然存在。
现在您可能只想下载最新的 Live555 源代码并编译它……它不起作用。 VLC 引用的函数名称和结构发生了变化，因此 VLC 不会针对源代码进行编译。您需要获取旧版本，我专门使用了这个版本，它是 2020 年的调整快照，发生在 mod阻止 VLC 编译的通知之前：
https://github.com/rgaufman/live555
你想要的配置是./genMakefiles linux-with-shared-libraries，我不知道是否需要，但由于我的系统是x86-64位，所以我先在编译器选项中添加了-m64
编译安装后，我继续编译VLC，将根Live555文件夹放入VLC extras文件夹后添加'--enable-live555'和'--with-live555-tree=extras/live555-master'，但是VLC编译失败，结果Live555 的 make install 不会将所有需要的 header 文件复制到 VLC 所在的位置。它们作为 4 个子文件夹放入 /usr/local/include/，实际的库放入 /usr/local/lib/。添加正确的 CXX/CPP 标志将使它看起来像放置它们的位置，但是我将它们全部放在一个文件夹中并使用了 1 个标志。
我还必须 '--disable-mod' 解决我没有兴趣修复的依赖版本问题，因为我不使用 modplug 或任何 mod 文件。
50分钟后...VLC编译成功！然而，它期望 Live555 的库位于 /usr/lib/ 而不是 /usr/local/lib/，因为编译花费了很长时间，我很好地将库链接或复制到预期的文件夹中，然后VLC 在链接到新文件时与 RTSP 一起工作。或者，如果您需要加载相机源，您可以选择保留原始 VLC 和 运行 直接新文件。
我有同样的问题，vlc 不支持 rtsp。我找到了两个解决方案。
1 - 使用 snap 版本
sudo snap install vlc => rtsp 正在运行。
/snap/bin/vlc rtsp://...
2 - 重建 vlc。我用这个教程来帮助我：https://wiki.videolan.org/UnixCompile/ 我在 ./configure 上遇到了一些问题，所以我安装了一些非强制性的包..但我不知道是哪一个..所以我列出了我在测试期间安装的所有包。
sudo apt-get build-dep vlc vlc-plugin-qt phonon4qt5-backend-vlc
sudo apt-get install libqscintilla2-qt5-dev libqt5charts5-dev qtdeclarative5-dev libqt5gstreamer-dev libqt5opengl5-dev phonon4qt5-backend-vlc libqt53dcore5 qtquickcontrols2-5-dev
git clone git://git.videolan.org/vlc.git
cd vlc
./bootstrap
cd contrib
mkdir native
cd native
../bootstrap
make (stop with error : protoc system version 3.12.4 and required version 3.1.0 do not match)
cd ../../
./configure --prefix=/usr/local --enable-merge-ffmpeg --enable-live555
make
现在我有了一个支持 rtsp 的 vlc。
