ENUM DMX_OUTPUT(9)

✨ NAME ✨

enum dmx_output — the output for the demux 💖

okay so this little enum is literally the "where does the stream go" menu for the demux, and each constant picks a destination. let's get into it, bestie 🫶

🌸 SYNOPSIS 🌸

enum dmx_output {
    DMX_OUT_DECODER ,
    DMX_OUT_TAP ,
    DMX_OUT_TS_TAP ,
    DMX_OUT_TSDEMUX_TAP

};

💅 Constants

• DMX_OUT_DECODER — streaming directly to the decoder. no detours, no middlemen, straight to the decoder, slay ✨
• DMX_OUT_TAP — output going to a memory buffer (to be retrieved via the read command). delivers the stream output to the demux device on which the ioctl is called. so like, the buffer is yours to read back out, iykyk 🎀
• DMX_OUT_TS_TAP — output multiplexed into a new TS (to be retrieved by reading from the logical DVR device). routes output to the logical DVR device /dev/dvb/adapter?/dvr?, which delivers a TS multiplexed from all filters for which DMX_OUT_TS_TAP was specified. one DVR device, all your TS_TAP filters muxed together — iconic 👑
• DMX_OUT_TSDEMUX_TAP — like DMX_OUT_TS_TAP but retrieved from the DMX device. same vibe, different device to read from, periodt 💀
