How can I add custom metadata to an MXF using FFMPEG ?
15 septembre 2021, par Zak44I am trying to add custom metadata to an MXF in FFMPEG. I can get the syntax to go through and then my metadata to be listed during the command output, but when I later run FFMPEG on the file to check the metadata is not there. Only the material_package_name will stick. Is this not possible with MXF ?


Command :


ffmpeg -i Test.mp4 -vf scale=1920:1080 -an -metadata project="TEST PROJECT" -metadata comment="Test Comment" -metadata artist="Test" -metadata material_package_name="TEST VID CLIP" -b:v 36M -f mxf_opatom "TEST_VID_CLIP.mxf"


Output from command :

swscale/graph : add new high-level scaler dispatch mechanism
10 octobre 2024, par Niklas Haasswscale/graph : add new high-level scaler dispatch mechanism
This interface has been designed from the ground up to serve as a new
framework for dispatching various scaling operations at a high level. This
will eventually replace the old ad-hoc system of using cascaded contexts,
as well as allowing us to plug in more dynamic scaling passes requiring
intermediate steps, such as colorspace conversions, etc.The starter implementation merely piggybacks off the existing sws_init() and
sws_scale(), functions, though it does bring the immediate improvement of
splitting up cascaded functions and pre/post conversion functions into
separate filter passes, which allows them to e.g. be executed in parallel
even when the main scaler is required to be single threaded. Additionally,
a dedicated (multi-threaded) noop memcpy pass substantially improves
throughput of that fast path.Follow-up commits will eventually expand this to move all of the scaling
decision logic into the graph init function, and also eliminate some of the
current special cases.Sponsored-by : Sovereign Tech Fund

Process vide files to take screen grabs in java spring boot
10 octobre 2023, par Haleema KhanI am using JavaCV library with ffmpeg bindings to process video files and taking screen grabs at specific frames.
Adding JavaCV library dependency to my spring project increases the size of my jar file from around 90Mb > 1+ Gb.
This is a big issue becuase my project is deployed on AWS elastic beanstalk that accepts a max size of 500 Mb for a jar file.


Need help to resolve this issue with the jar file or else any other alternate library that could do this.


What I tried : I have removed all accept the abosultely necessary dependencies in my project to reduce the jar size.
I have also tried to find alternate solutions but couldnt get anything.
