Some #ffmpeg wizards her?
I want to re-encode a video on another computer.
ffmpeg -i video.mkv tells me:

Stream #0:0: Video: h264 (High), yuv420p(progressive), 1920x800 [SAR 1:1 DAR 12:5], 23.98 fps, 23.98 tbr, 1k tbn
Metadata:
title : x264 Video Stream
Stream #0:1(ger): Audio: dts (DTS-ES), 48000 Hz, 6.1, fltp, 1536 kb/s
Metadata:
title : German DTS-ES 6.1 WARNER Fix
Stream #0:2(eng): Audio: dts (DTS-ES), 48000 Hz, 6.1, fltp, 1536 kb/s
Metadata:
title : English DTS-ES 6.1
Stream #0:3(ger): Subtitle: ass
Metadata:
title : Forced-Subs
Stream #0:4: Attachment: ttf
Metadata:
filename : GDSC____.PFB
mimetype : application/x-font
Stream #0:5: Attachment: none
Metadata:
filename : GDSC____.PFM
mimetype : application/octet-stream

OK, I am only interested in the first three streams (0:0, 0:1 and 0:2).
I run:

❯ pv video.mkv | ssh othercomputer 'ffmpeg -f matroska -y -i pipe:0 -v warning -map 0:0 -map 0:1 -map 0:2 -c:a libopus -b:a 96k -c:v librav1e -qp 80 -speed 4 -tile-columns 2 -tile-rows 2 -f matroska -' > 1.mkv

And get:

[matroska,webm @ 0x55facbe5e900] Could not find codec parameters for stream 5 (Attachment: none): unknown codec

But why? I told ffmpeg to ignore all streams execpt the first three.

Die Tochter hatte am Gymnasium über mehrere Monate ein Theaterprojekt. Also sie haben sich mit einer Thaterpädagogin ein Stück selber geschrieben/erabeitet/gespielt. Tolle Sache!
Ein Tonstudio hat das aufgenommen und die Aufnahme zur Verfügung gestellt.
Ein mp4 in 4k, satte 33 Gigabyte.

Das kann man verbessern:

pv "White Cappucino.mp4" | ffmpeg -y -i pipe:0 -hide_banner -loglevel error -c:v libvpx-vp9 -crf 31 -b:v 0 -deadline best -preset veryslow -threads 12 'White Cappucino.webm'
