Does ffmpeg supported KLV metadata?

Question

Is ffmpeg metadata, which is also described in: http://wiki.multimedia.cx/index.php?title=FFmpeg_Metadata also supported MISB standard UAV metadata 601.5 ? Is it same as KLV ?

Answer 1

I'm unsure if UAV metadata 601.5 is the same as KLV, but FFmpeg can demux KLV metadata since commit 69a042e from 28 Oct 2013:

• mpegts: demux synchronous SMPTE 336M Key-Length-Value (KLV) metadata

This fixes ticket #2579: Data stream from UAV video reported as "Unknown" type and without codec_id set, so you may find other relevant information there too.
