libdvbtee
1.0.0
libdvbtee 是一个用于 MPEG2 传输流的流解析器和服务信息聚合器库。该库包括节目服务信息 (PSI) 解析器并支持各种网络流媒体方法，并且支持 linux-dvb 内核 API 以及 HDHomeRun 网络流媒体 API。
该库包含足够的功能来支持全功能电视中间件应用程序，包括通过 UDP、TCP、HTTP、DMA 和各种其他机制获取和传输数据的能力。
libdvbtee_server允许从 http 会话或命令行界面控制这些功能，并且可用于控制多个调谐器。
libdvbtee_parser是一个从 libdvbtee 源构建的库，供 node-dvbtee 使用。 libdvbtee_parser与libdvbtee托管在同一 git 开发存储库中，因此，它们共享同一个 README.md 文件。
dvbtee 可执行应用程序提供多种功能，包括：扫描、调谐、EPG 浏览、接收传入网络流、流出网络流、管理多个调谐器等等...
可以通过 telnet 或 http 访问服务器。默认端口号为64080 ，但这是可配置的。 server_example使用端口号62080 。
通过 http 访问服务器时，命令前面加上 /，参数前面加上 =。通过 telnet 访问服务器时，输入“command=argument”形式，然后按 Enter 键。

构建 libdvbtee 的推荐方法是使用build-auto.sh脚本：
./build-auto.sh
dvbtee/dvbtee < mpegfile.ts
libdvbtee 最初是使用 qmake 构建系统开发的，以实现轻松的多平台构建支持。 libdvbtee 仍然支持 qmake 系统，但由于各种原因现在使用 autotools 作为首选构建系统。
autoreconf --install
./configure
make
dvbtee/dvbtee < mpegfile.ts
如果出于某种奇怪的原因，您想使用旧版本的表/描述符解码器构建 libdvbtee，请指定 --enable-olddecoder 进行配置
autoreconf --install
./configure --enable-olddecoder
make
dvbtee/dvbtee < mpegfile.ts
如果您更喜欢使用 qmake 而不是 autotools，请使用以下命令：
qmake -r
make
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts
如果出于某种奇怪的原因，您想使用旧版本的表/描述符解码器构建 libdvbtee，请在 qmake 中指定 CONFIG+=olddecoder
qmake -r CONFIG+=olddecoder
make
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts
libdvbtee 依赖 libdvbpsi 进行 PSIP 解析。尽管 libdvbtee 将针对较旧的 libdvbpsi 版本进行构建，但需要更新的构建才能提供 libdvbtee 的所有最新功能，例如 ATSC 支持。
libdvbtee 的构建系统能够通过将 libdvbpsi 存储库的副本放置在 libdvbtee 源代码树的顶层来构建和链接最新版本的 libdvbpsi。
本 README 中没有提供分步说明，而是提供了 shell 脚本来获取最新的 libdvbpsi 源、配置构建系统并一起构建两个库。
对于使用 autotools 集成构建 libdvbtee 以及最新版本的 libdvbpsi（推荐）：
./build-auto.sh
dvbtee/dvbtee < mpegfile.ts
对于使用 qmake 集成构建 libdvbtee 以及最新版本的 libdvbpsi：
./build-qmake.sh
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts

要调谐到物理通道 33 的服务 ID 1 并将其流式传输到 udp 端口：
dvbtee -c33 -I1 -oudp://192.168.1.100:1234
要调整适配器 1 的第二个前端并将物理通道 44 的完整 TS 流式传输到 TCP 侦听器：
dvbtee -c44 -otcp://192.168.1.200:5555
要侦听 TCP 端口并流式传输到 UDP 端口：
dvbtee -itcp://5555 -oudp://192.168.1.100:1234
要解析捕获的文件并过滤掉 PSIP 数据，将 PAT/PMT 和 PES 流保存到文件中：
dvbtee -Finput.ts -O3 -ofile://output.ts
要解析 UDP 流 10 秒：
dvbtee -iudp://127.0.0.1:1234 -t10
要使用第一个连接的调谐器扫描服务：
dvbtee -s -a0
要使用针对速度和部分冗余进行优化的 5 个调谐器扫描 ClearQAM 服务：
dvbtee -A2 -T5 -s4
要使用 2 个针对速度和冗余进行优化的 HdHomeRun 调谐器扫描 ATSC 服务：
dvbtee -A1 -H -T2 -s3
要使用适配器 0 启动服务器：
dvbtee -a0 -S
要使用特定 HdHomeRun 设备的tuner1 启动服务器（例如：ABCDABCD）：
dvbtee -H ABCDABCD-1 -S
要扫描启用 JSON 输出的通道，请使用以下命令：
dvbtee -s -c13 -j
...应该生成类似于以下内容的输出：
