[FFmpeg-user] editing video stream with KLV metadata

Thu May 3 17:21:29 EEST 2018

Hello,

I have a videostream with klv metadata that I want to edit while keeping the metadata.
I'm wondering if it's possible with ffmpeg?

I tried several command lines, the two most relevant being the two below I believe.
However, in both cases I only get the video stream...

I also tried to retrieve the metadata in a file with
ffmpeg -ss 00:02:15.0 -i video_out_2018_05_01_14_11_53.ts -f ffmetadata testMetadata.txt
But that gives a file containing: ;FFMETADATA1 encoder=Lavf58.13.100
As if it was using data from the video stream and not the data stream.

Thanks for any help!
Claire
