/************* VLC PLUGINS FOR THE MULTITHREADED VVC DECODER BASED ON VTM  ************/

See also the README.md files inside the following subfolders for build instructions.

./DecoderPluginVLC  VVC video decoder plugin making use of the VTM decoder lib

./TsDemuxPluginVLC  TS demux with a new es vvc stream format ID

/************* Installation and usage  ************/

Tested with VLC 3.0.9.2 and 3.0.12 64-bit versions (Windows)

1. Install VLC

- download VLC media player.

- unpack in (for example) C:\VLC

note: in order to use windows compiled binaries (which are 64-bits), the 64-bits version of VLC is required

2. Install plugin and decoder dlls

- copy decoder plugin and VTM decoder dll into plugin directory:

  ....VLC\plugins\codec\

- to play ts files, add the ts-demux plugin libvvctsdemux_plugin.dll to:

  ....VLC\plugins\demux\

3. Try to play a VVC binary file

It tries to follow frame rate from HRD information if coded, otherwise targets 50 Hz.

If playing a ts, it uses ts timestamps and find fps with consecutive timestamps.

Additional parameters control the behaviour of the decoder, and can be set either

from the command line of from the configuration dialog: go to Tools / Preferences,

select "show allow parameters" on the bottom-left, then look for Input/codecs /

Video codecs / vvcdec.
