But -map 0 -movflags +faststart does not keep _all_ metadata
<lockywolf>
"Tagged date, xyz, com.android.version, com.android.video.temporal_layers_count" are lost
<lockywolf>
while I can understand why android-related tags may be not preserved, Tagged date and xyz are _very_ useful
<furq>
neither of those options have anything to do with metadata
<furq>
you probably want -map_metadata 0

furq: I have found 3 metadata-related issues on Trac

all seem to be about the same thing

ffmpeg seems to actually copy the metadata, but not in the way that most devices understand. at least Apple and Mediainfo don't

To precisely seek to a specific frame in an h264 video, does it need to compute all previous frames?
<Rammstein>
I have a source video that is 90 minutes long and I want just one minute out of it. When I try to re-encode the video with -ss 01:20:00 -to 01:21:00, it takes a long time before it even starts encoding. Is this normal?
<furq>
put those options before -i if you want it to actually seek
<furq>
assuming the input isn't mpegts or something with no seek index
<Rammstein>
Ah, okay. If it seeks this way, would there be any audio sync issues?
<furq>
hopefully not

Great. This works! So I've been doing this wrong for the last 10 years or longer and just thought of asking today.

got our stuff largely working directx11 so taking a quick look at dx12 video APIs. the only win seems to be decode can be done multiple threads which I don't need for playback & encode which we currently don't need has this thingy ID3D12VideoMotionEstimator which apparently you have an equivalent of already. dunno if it's useful as no experience in this area. fyi.

might be worth it for perhaps better management of reference frames. need to study it some more.
