[FFmpeg-devel] Forgejo PR to add libomt OpenMediaTransport support
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 Mark Gilbert ___ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
[FFmpeg-devel] Patches to add libomt OpenMediaTransport support to FFmpeg

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 Best Regards Mark Gilbert ___ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".

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