👑 DVBLAST(1) 👑 (User Commands)

okay so bestie, sit down, hydrate, because this is the manual page for DVBlast — yes, the dvblast you keep seeing in your process list — and it lives in the User Commands section of your man pages. It's a whole vibe and it's lowkey iconic, so let's get into it. 💅

✨ NAME ✨

yeah, that's a lot of flags. she's thorough. we respect that. 💖

🌸 DESCRIPTION 🌸

So DVBlast is a simple and powerful streaming application built on the linux-dvb API. What it does, step by step, is: it opens a DVB device, tunes it, places PID filters, configures a CAM module, and demultiplexes the packets out to several RTP outputs. That's the whole arc. main character energy fr. ✨

DVBlast is designed to be the core of a custom IRD or CID, based on a PC with Linux-supported DVB cards. iykyk.

🚨 okay so important vibe check: DVBlast does not do any kind of processing on the elementary streams — no transcoding, no remultiplexing, none of that. and it does not stream from plain files, only DVB devices. if that's what you were looking for… switch to VLC. no cap. 😭

💅 OPTIONS 💅

every single one, bestie. no skipping. let's go. 🫶

• -a, --adapter <adapter> — Address of the adapter. that's it, that's the whole thing.
• -A, --asi-adapter — Read packets from an ASI adapter (0-n). If support for Deltacast ASI cards is compiled in, prefix the adapter number with "deltacast:" to select a Deltacast input. Deltacast inputs are numbered as (100 * card number) + channel number. math but make it niche 💀
• -b, --bandwidth <bandwidth> — Frontend bandwidth.
• -B, --provider-name <name> — Service provider name to declare in the SDT. Wanna change the provider name per output? use the /srvprovider= output option in the config file. obsessed with the flexibility ngl.
• -c, --config-file <config file> — Use the given configuration file.
• -C, --dvb-compliance — Pass through or build the mandatory DVB tables.
• -d, --duplicate <dest IP:port> — Duplicate all received packets to a given destination.

• --multistream-id-pls-mode <ROOT|GOLD|COMBO> — Set PLS mode used in multistream-id calculation. Possible values are: ROOT GOLD and COMBO (default: ROOT). If this option is set multistream-id option is overwritten.
• --multistream-id-pls-code <0-262143> — Set PLS code used in multistream-id calculation. Possible values are in range 0..262143 (default: 0). If this option is set multistream-id option is overwritten.

okay that's the whole page, and we did not skip a single flag, not one. and like — this is DVBlast 2.2, from April 2012, and yes the manual page is literally called DVBLAST(1) because that's just how man pages do. slay. periodt. 💅✨
