3 years ago ffmpeg -v error -i videoOutput.mp4 -f null - 2>error.log
On original file this logs no errors, but on remuxed one I get:

BTW, thanks for the package :pray: I'll look into transcode.go, might get better idea
With ffmpeg I achieve this with: ffmpeg -i in.FORMAT -map_metadata -1 -c:v copy -c:a copy out.FORMAT It leaves width/height/bitrate etc and removes GPS location, which is what I want. Can I achieve the same using gmf?
I tried remuxing with the example, replaced CloseInput()/CloseOutput() with CloseInputAndRelease/CloseOutputAndRelease https://github.com/3d0c/gmf/blob/master/examples/remuxing.go
Which did the job of removing that metadata but created a file 2 mb smaller than original and seems to be corrupt, vlc can't play it properly, video is skippy and vlc shows errors: [h264 @ 0x7fe894004e80] get_buffer() failed [h264 @ 0x7fe894004e80] thread_get_buffer() failed [h264 @ 0x7fe894004e80] decode_slice_header error [h264 @ 0x7fe894004e80] no frame!
I'm trying to figure it out myself but if anyone could point me in the right direction it would be very helpful.
