[FFmpeg-devel] Forgejo PR to add libomt OpenMediaTransport support

2025-10-18 Thread ffmpeg--- via ffmpeg-devel
Hi Folks

We are part of the group creating a new open source and free to use 
professional IP Video protocol called OMT (open media transport)
It's similar to NDI in many ways, but completely open source and royalty free.

We have have already completed implementation of this protocol into FFMPEG 8 
and have created a Pull Request via forgejo
https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20694

Perhaps a maintainer can take a look at this ?

---

The protocol is officially  launched and is already gaining lots of attention 
from companies in the broadcast industry. Already quite a few broadcast vendors 
have lready announced or released support, including Sienna VMix, Drastic, 
Garanin and others.

You can read about it here:
https://openmediatransport.org/
and 
https://github.com/openmediatransport/
The github includes the full source code of OMT and its underlying codec VMX, 
along with binaries, and links to free utilities leveraging OMT across the 3 
major platforms.

The video codec used in OMT is actually the same as the vmix codec which is 
already implemented in decoder-only form in FFMPEG.

We have have already completed implementation of this protocol into FFMPEG 8 
and have created a Pull Request via forgejo
https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20694

To build FFMPEG with OMT from the OMT patched FFmpeg source:

Download the OMT libraries and header folder from. 
https://github.com/openmediatransport/. 
or easier :
https://github.com/GalleryUK/OMTLibsAndHeaders
place the OMT folder with include and lib NEXT to the FFmpeg folder

Then Configure with : 

Linux:
./configure  --enable-libomt --extra-cflags="-I$(pwd)/../OMT/include" 
--extra-ldflags="-L$(pwd)/../OMT/lib -Wl,-rpath,\$ORIGIN/../OMT/lib"

Mac:
./configure  --enable-libomt --extra-cflags="-I$(pwd)/../OMT/include" 
--extra-ldflags="-L$(pwd)/../OMT/lib  -Wl,-rpath,@loader_path/../OMT/lib"


Please let me know if you have any questions

Best Regards

[FFmpeg-devel] Patches to add libomt OpenMediaTransport support to FFmpeg

2025-08-19 Thread ffmpeg--- via ffmpeg-devel
Hi Folks

We are part of the group creating a new open source and free to use 
professional IP Video protocol called OMT (open media transport)
It's similar to NDI in many ways, but completely open source and royalty free.

The protocol is now officially  launched and is already gaining lots of 
attention from companies in the broadcast industry.

You can read about it here:
https://openmediatransport.org/
and 
https://github.com/openmediatransport/
The github includes the full source code of OMT and its underlying codec VMX, 
along with binaries, and links to free utilities leveraging OMT across the 3 
major platforms.

The video codec used in OMT is actually the same as the vmix codec which is 
already implemented in decoder-only form in FFMPEG.

We have have already completed implementation of this protocol into FFMPEG 7 
and I enclose patches to add this to the current FFmpeg origin/master.


If the .eml patches dont make it through the email, here are links to them:
https://www.sienna-tv.com/omt/0001-Added-libomt-support-for-OpenMediaTransport.eml
https://www.sienna-tv.com/omt/0002-Patched-libomt-into-FFmpeg.eml


To build this also requires the pre-built omt libraries which are available at  
 
https://github.com/openmediatransport/libomtnet/releases
also, available from:
https://www.sienna-tv.com/omt/OMTlibs.zip

Finally We have published the entire source code for ffmpeg with libomt 
integrated at:
https://github.com/GalleryUK/FFmpeg-OMT

Please let me know if you have any questions

[FFmpeg-devel] [PATCH] WIP: fftools/opt_common: add separator line to show_filters output (PR #20547)

2025-09-18 Thread add-uos-ffmpeg via ffmpeg-devel
PR #20547 opened by add-uos-ffmpeg
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20547
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20547.patch

Add a separator line to show_filters() function output to maintain
consistent formatting with other show functions like show_codecs,
show_formats_devices, etc. This provides uniform formatting across
all command-line output functions for better readability and
parsing by external tools.
