libdvbtee_parser

## dvbtee & libdvbtee #### Introduction libdvbtee is a stream parser and service information aggregator library for MPEG2 transport streams. The library includes a program service information (PSI) parser and support for various network streaming methods and is aware of the linux-dvb kernel API as well as HDHomeRun network streaming APIs. The library contains enough functionality to power a full featured television middleware application, including the ability to acquire and stream data through UDP, TCP, HTTP, DMA and various other mechanisms. `libdvbtee_server` allows for these features to be controlled from an http session or command line interface, and can be used to control multiple tuners. `libdvbtee_parser` is a library built from [libdvbtee](https://github.com/mkrufky/libdvbtee) sources for use by [node-dvbtee](https://www.npmjs.com/package/dvbtee) `libdvbtee_parser` is hosted within the same git development repository as `libdvbtee` and as such, they share this same single README.md file. The dvbtee executable application provides a variety of features, including: scanning, tuning, EPG browsing, receive incoming network streams, stream out network streams, manage multiple tuners, and more... The server can be accessed either by telnet or http. The default port number is `64080`, but this is configurable. The `server_example` uses port number `62080`. When accessing the server via http, precede commands by / and arguments by =. When accessing the server via telnet, enter in the form 'command=argument' and press enter. Michael Ira Krufky mkrufky at linuxtv dot org #### How to build / run The recommended way to build libdvbtee is by using the `build-auto.sh` script: ``` ./build-auto.sh dvbtee/dvbtee < mpegfile.ts ``` #### Other build methods libdvbtee was originally developed using the qmake build system for easy multi-platform build support. libdvbtee still supports the qmake system, but now uses autotools as the preferred build system for various reasons. ``` autoreconf --install ./configure make dvbtee/dvbtee < mpegfile.ts ``` If, for some odd reason, you want to build libdvbtee using the old version of the table / descriptor decoder, specify --enable-olddecoder to configure ``` autoreconf --install ./configure --enable-olddecoder make dvbtee/dvbtee < mpegfile.ts ``` If you prefer to use qmake rather than autotools, use the following commands: ``` qmake -r make LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts ``` If, for some odd reason, you want to build libdvbtee using the old version of the table / descriptor decoder, specify CONFIG+=olddecoder to qmake ``` qmake -r CONFIG+=olddecoder make LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts ``` libdvbtee depends on libdvbpsi for PSIP parsing. Although libdvbtee will build against older libdvbpsi releases, a more recent build is required in order to provide all of libdvbtee's latest features, such as ATSC support. libdvbtee's build system is capable of building and linking against the latest version of libdvbpsi by placing a copy of the libdvbpsi repository in the top level of libdvbtee's source tree. Rather than giving step-by-step instructions in this README, shell scripts are provided that will fetch the latest libdvbpsi sources, configure the build system, and build both libraries together. For the integrated build of libdvbtee along with the latest version of libdvbpsi using autotools (recommended): ``` ./build-auto.sh dvbtee/dvbtee < mpegfile.ts ``` For the integrated build of libdvbtee along with the latest version of libdvbpsi using qmake: ``` ./build-qmake.sh LD_LIBRARY_PATH=libdvbtee:libdvbtee_server dvbtee/dvbtee < mpegfile.ts ``` #### Command line arguments ``` -a adapter id -A (1 for ATSC, 2 for ClearQAM) -b display bitrates & statistics -c channel to tune / comma (,) separated list of channels to scan / scan minimum channel -C channel to tune / comma (,) separated list of channels to scan / scan maximum channel -f frontend id -F filename to use as input -t timeout -T number of tuners (dvb adapters) allowed to use, 0 for all -s scan, optional arg when using multiple tuners: 1 for speed, 2 for redundancy, 3 for speed AND redundancy, 4 for optimized speed / partial redundancy -S server mode, optional arg 1 for command server, 2 for http stream server, 3 for both -i pull local/remote tcp/udp port for data -n bind to a specific network interface -I request a service and its associated PES streams by its service id -E enable EPG scan, optional arg to limit the number of EITs to parse -e enable ETT extended text tables (EPG descriptions, ATSC only) -o output filtered data, optional arg is a filename / URI, ie udp://127.0.0.1:1234 -O output options: (or-able) 1 = PAT/PMT, 2 = PES, 4 = PSIP, 8 = AUDIO, 16 = VIDEO -H use a HdHomeRun device, optional arg to specify the device string -j enable json output of decoded tables & descriptors -d debug level -q quiet most logging -h display additional help ``` #### Example Usage To tune to service id 1 of physical channel 33 and stream it to a udp port: ``` dvbtee -c33 -I1 -oudp://192.168.1.100:1234 ``` To tune the second frontend of adapter 1 and stream the full TS of physical channel 44 to a tcp listener: ``` dvbtee -c44 -otcp://192.168.1.200:5555 ``` To listen to a TCP port and stream to a UDP port: ``` dvbtee -itcp://5555 -oudp://192.168.1.100:1234 ``` To parse a captured file and filter out the PSIP data, saving the PAT/PMT and PES streams to a file: ``` dvbtee -Finput.ts -O3 -ofile://output.ts ``` To parse a UDP stream for ten seconds: ``` dvbtee -iudp://127.0.0.1:1234 -t10 ``` To scan for services using the first connected tuner: ``` dvbtee -s -a0 ``` To scan for ClearQAM services using 5 tuners optimized for speed and partial redundancy: ``` dvbtee -A2 -T5 -s4 ``` To scan for ATSC services using 2 HdHomeRun tuners optimized for speed and redundancy: ``` dvbtee -A1 -H -T2 -s3 ``` To start a server using adapter 0: ``` dvbtee -a0 -S ``` To start a server using tuner1 of a specific HdHomeRun device (ex: ABCDABCD): ``` dvbtee -H ABCDABCD-1 -S ``` #### Example output: To scan a channel with JSON output enabled, the following command: ``` dvbtee -s -c13 -j ``` ...should generate output similar to the following: ``` scan channel
