The VideoLAN Forums

Hi all,

I have an external DMO decoder which is called let's say dmodecxxx.dll. I read somewhere that such codecs can be used in VLC. If anyone has any experience with this could you please post a sample of command which I can use to play the file with such an external decoder. Is there any specific folder where I should put that decoder.

Thanks,
t

If you haven't registered the codec to the system, you have to edit VLC code to get it working. If you have registered it, --codec dmo switch from command-line should work.

Look at modules/codec/dmo/ for the code of VLC.

i was wondering og using external codec on windows, thank you

How to compile VVC H266 MPEGi Versalite Video Coding decoder for Linux for VideoLan usage?
Full Version 1.0.1 is avaible as open source:
https://github.com/fraunhoferhhi/vvdec

There are even:
VLCReader.cpp
VLCReader.h

in:
tree/master/source/Lib/DecoderLib
https://github.com/fraunhoferhhi/vvdec/ ... DecoderLib

I have heard it can be compiled even for running on:
iPhone 12pro Soc ( Apple A14 SoC)

results:
FHD: 53fps (RA and LB)
UHD: 32fps (RA)

https://arxiv.org/abs/2103.03612




This plugin for VideoLan only runs Annex B byte order streams:
https://github.com/TencentCloud/O266player
(Tencent O266dec plugin is a plugin for VLC player that enables VLC to play H.266 Annex B bit streams)




From other external video codecs worth interesting is:
Free version of Mpeg5 part 1 = Essential Video Coding Baseline Profile patent Free.
https://github.com/revcx/revc
Version written in RUST.

Mind you provide a binary plugin which works with VLC 3.0.12 and a video sample for testing purposes ?
It would be nice

Compiling Code for Linux, Windows, or Mac OSx, or iPhone may not be that hard.

Much harder is compiling VideoLan
with this files:
There are even:
VLCReader.cpp
VLCReader.h

in:
tree/master/source/Lib/DecoderLib
https://github.com/fraunhoferhhi/vvdec/ ... DecoderLib

As I do not really know what to do with this,
And I have Knoppix hybrid 64bit 32bit core.
So is much more complicated for me, because I need Linux cross compiling.
(compiling both VideoLC player and VVC for 64bit)
However such things can be done on:
Windows & Wine.



There are already flags in CMakeLists.txt file for:
VVDEC_ENABLE_X86_SIMD
VVDEC_ENABLE_ARM_SIMD
APPLE
DEFINED CMAKE_OSX_ARCHITECTURES
CMAKE_OSX_ARCHITECTURES
CMAKE_HOST_SYSTEM_PROCESSOR

So I suppose VVC can be already compiled for OSx, iPhone,

Not many people remember that: VVC was called Future Video Coding (FVC)
and one of the objective / aims was that FVC would be Open Source.

Mind you provide a binary plugin which works with VLC 3.0.12 and a video sample for testing purposes ?
It would be nice

I suppose someone could publish some scripts how to do it on Knoppix.
Compilation is easy task that can be automated.
But These files: VLCReader.cpp , VLCReader.h
I suppose need to be compiled togather with videoLan.

What is more
I suppose, someone could compile it for Android and Linux Boxes enigma2 and other dvbS2 receivers.


According to German wiki in June 2021, and that is in 2-3 months there will be ready hardware decoding, and I suppose even coding.
(I suppose that it will be computer plans for it, then Chips could be made.
However chips manufacturers have 6months waiting list for production and shipping ! )

I doubt binaries can be published.
But I suppose, some software could be written, that all that process could be done with just One Button,
even by Complete Newbie!

Just like there are Flash Disk / pendrive installers when you can have live boot with Windows or Linux.

By the way, VVC will have 4 switchable patent pools, just like mpeg-5 have switchable 21 Tools.
So no single company can have hold on whole VVC.
