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.
