dvbtee 和 libdvbtee

介紹

libdvbtee 是一個用於 MPEG2 傳輸流的流解析器和服務資訊聚合器函式庫。該程式庫包括節目服務資訊 (PSI) 解析器並支援各種網路串流方法，並且支援 linux-dvb 核心 API 以及 HDHomeRun 網路串流 API。

該庫包含足夠的功能來支援全功能電視中間件應用程序，包括透過 UDP、TCP、HTTP、DMA 和各種其他機制獲取和傳輸資料的能力。

libdvbtee_server允許從 http 會話或命令列介面控制這些功能，並且可用於控制多個調諧器。

libdvbtee_parser是一個從 libdvbtee 來源建置libdvbtee函式庫，供 node- libdvbtee_parser使用。

dvbtee 可執行應用程式提供多種功能，包括：掃描、調諧、EPG 瀏覽、接收傳入網路串流、流出網路串流、管理多個調諧器等等...

可以透過 telnet 或 http 存取伺服器。預設連接埠號碼為64080 ，但這是可設定的。 server_example使用連接埠號碼62080 。

透過 http 存取伺服器時，命令前面加上 /，參數前面加上 =。透過 telnet 存取伺服器時，輸入「command=argument」形式，然後按 Enter 鍵。

如何建置/運行

建置 libdvbtee 的建議方法是使用build-auto.sh腳本：

 ./build-auto.sh
dvbtee/dvbtee < mpegfile.ts

其他建置方法

libdvbtee 最初是使用 qmake 建置系統開發的，以實現輕鬆的多平台建置支援。 libdvbtee 仍然支援 qmake 系統，但由於各種原因現在使用 autotools 作為首選建置系統。

 autoreconf --install
./configure
make
dvbtee/dvbtee < mpegfile.ts

如果出於某種奇怪的原因，您想要使用舊版本的表/描述符解碼器建立 libdvbtee，請指定 --enable-olddecoder 進行配置

 autoreconf --install
./configure --enable-olddecoder
make
dvbtee/dvbtee < mpegfile.ts

如果您喜歡使用 qmake 而不是 autotools，請使用以下命令：

 qmake -r
make
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts

如果出於某種奇怪的原因，您想要使用舊版本的表/描述符解碼器來建立 libdvbtee，請在 qmake 中指定 CONFIG+=olddecoder

 qmake -r CONFIG+=olddecoder
make
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts

libdvbtee 依賴 libdvbpsi 進行 PSIP 解析。儘管 libdvbtee 將針對較舊的 libdvbpsi 版本進行構建，但需要更新的構建才能提供 libdvbtee 的所有最新功能，例如 ATSC 支援。

libdvbtee 的建置系統能夠透過將 libdvbpsi 儲存庫的副本放置在 libdvbtee 原始碼樹的頂層來建置和連結最新版本的 libdvbpsi。

本 README 中沒有提供逐步說明，而是提供了 shell 腳本來取得最新的 libdvbpsi 來源、配置建置系統並一起建置兩個函式庫。

對於使用 autotools 整合建置 libdvbtee 以及最新版本的 libdvbpsi（推薦）：

 ./build-auto.sh
dvbtee/dvbtee < mpegfile.ts

對於使用 qmake 整合來建立 libdvbtee 以及最新版本的 libdvbpsi：

 ./build-qmake.sh
LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts

用法範例

若要調諧至實體通道 33 的服務 ID 1 並將其串流傳輸到 udp 連接埠：

  dvbtee -c33 -I1 -oudp://192.168.1.100:1234

若要調整適配器 1 的第二個前端並將實體通道 44 的完整 TS 串流傳輸到 TCP 偵聽器：

  dvbtee -c44 -otcp://192.168.1.200:5555

若要偵聽 TCP 連接埠並串流傳輸至 UDP 連接埠：

  dvbtee -itcp://5555 -oudp://192.168.1.100:1234

要解析捕獲的檔案並過濾掉 PSIP 數據，將 PAT/PMT 和 PES 流保存到檔案中：

  dvbtee -Finput.ts -O3 -ofile://output.ts

要解析 UDP 流 10 秒：

  dvbtee -iudp://127.0.0.1:1234 -t10

要使用第一個連接的調諧器掃描服務：

  dvbtee -s -a0

若要使用針對速度和部分冗餘進行最佳化的 5 個調諧器掃描 ClearQAM 服務：

  dvbtee -A2 -T5 -s4

要使用 2 個針對速度和冗餘進行最佳化的 HdHomeRun 調諧器掃描 ATSC 服務：

  dvbtee -A1 -H -T2 -s3

若要使用適配器 0 啟動伺服器：

  dvbtee -a0 -S

若要使用特定 HdHomeRun 裝置的tuner1 啟動伺服器（例如：ABCDABCD）：

  dvbtee -H ABCDABCD-1 -S

輸出範例：

若要掃描啟用 JSON 輸出的頻道，請使用下列命令：

  dvbtee -s -c13 -j

....應該會產生類似以下內容的輸出：
