cvlc 不能播放 rtsp（omxplayer 可以）

Posted 2023-04-14

【中文标题】cvlc 不能播放 rtsp（omxplayer 可以）

【英文标题】：cvlc cannot play rtsp (omxplayer instead can)

【发布时间】：2021-12-14 09:40:23

【问题描述】：

得到这个大华 vto 流链接：与 omxplayer 一起使用，但 vlc 无法播放：

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 秒后可以正常播放。 谁能让我理解为什么 vlc 根本没有？

【问题讨论】：

我似乎有完全相同的问题。你会碰巧在运行 KDE 5.22 吗？我也怀疑这个问题更适合超级用户

'--disable-live555' 我认为这就是它不工作的原因，我在另一个启用了该功能的系统上编译了 VLC，它会很好地查看我的 ip cams。这提供了 RTSP/RTP access_demux 模块

感谢您的建议。实际上，我使用的是 Raspberry Pi OS 和带有 xfce 的 Debian buster。我尝试使用 --disable-live555 从源代码 v4 进行编译，但实际上由于其他原因编译失败。无论如何，帮助说：“通过live555禁用RTSP输入。（默认启用）”。

我实际上对此有一个非常详细的答案，尽管我要等到深夜才能得到它。确实是live555问题

【参考方案1】：

所以发生的事情是 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

两个活动版本是 2020.01.19-1 和 2018.11.26-1.1，Live555 已将 GPL 许可标头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。您需要获得一个旧版本，我专门使用了这个，它是 2020 年的调整快照，在阻止 VLC 编译的修改之前：

https://github.com/rgaufman/live555

你要的配置是./genMakefiles linux-with-shared-libraries，我不知道是不是必须的，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Live555根文件夹放入VLC extras文件夹后添加'--enable-live555'和'--with-live555-tree=extras/live555-master'，但是VLC编译失败，原来Live555的make install没有将所需的所有头文件复制到 VLC 正在查找的位置。它们作为 4 个子文件夹被放入 /usr/local/include/，实际的库被放入 /usr/local/lib/。添加正确的 CXX/CPP 标志会显示它们的放置位置，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' 解决一个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/ 中，因为编译需要很长时间，我可以将库链接或复制到预期的文件夹中，然后链接到新文件时，VLC 可与 RTSP 一起使用。或者，如果您需要加载相机源，您可以选择保留原始 VLC 并直接运行新文件。

【参考方案2】：

我也有同样的问题，vlc 不支持 rtsp。我找到了两个解决方案。

1 - 使用快照版本 sudo snap install vlc => rtsp 正在工作。

/snap/bin/vlc rtsp://...

2 - 重建 vlc。我用这个 tuto 来帮助我：https://wiki.videolan.org/UnixCompile/ 我的 ./configure 有一些问题，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。
