ErsatzTV and ffmpeg bogs down the PC and makes it unusable.

[Gryphon324]

I'm running plex and ersatz on a dell Optiplex 7010 running win10. It's an i7 with 4 cores. I'm also running with 16GB of ram. When I play just one show from the DVR guide from the plex app on my roku, or even on plexweb, ersatz/plex just clocks for about 60-120 seconds before it either plays or aborts. I watch the CPU performance and it pegs out at 100% and ffmpeg constantly shows at 70%-95%. On the other hand, when I play the very same show through plex, the CPU utilization is down around 15% or lower. Is there some sort of setting I can use to keep ffmpeg from making the PC unusable for viewing media through ersatz?

Creating a continuous IPTV stream has significantly higher requirements/overhead than streaming a single VOD item to a matching client (Plex has its own clients, ETV has no client).

There are basically two options to reduce CPU use:

1. Use a GPU for hardware acceleration
2. Use HLS Direct streaming mode (see docs)

HLS Direct is 100% a hack, but one that works with some clients to use very little CPU. TiviMate on Android is the one that most people use.

I'm having this issue as well. Even using hls direct fires something in ffmpeg and bogs down the machine. 6 cores all pegged at 100%. I've tried using Intel qsv but get an error:

HLS process for channel 2.1 has terminated unsuccessfully with exit code 1: [AVHWDeviceContext @ 000001a389ddbc40] Failed to create Direct3D device Device creation failed: -1313558101.

Even using hls direct fires something in ffmpeg and bogs down the machine

Note that if you are using Plex as a client, it does not support HLS Direct so ErsatzTV will force the channel to use MPEG-TS streaming mode regardless of the channel configuration.

Try HLS Direct with a client like MPV or TiviMate.

@ellisd4 this issue should be fixed on the latest release - ETV now uses Direct3D 11 on Windows for QSV (d3d11va instead of dxva2) which should work better in headless environments.
