Description

I try to recode a ogg vorbis file to a different audio rate. I want to keep the metadata. The plan is to dump the metadata to a file and then include it again in the second step.

The used file:
http://alternativlos.cdn.as250.net/alternativlos-30.ogg

Contained metadata:


Input #0, ogg, from 'alternativlos-30.ogg':

Duration: 02:55:17.21, start: 0.000000, bitrate: 75 kb/s

Stream #0:0: Audio: vorbis, 48000 Hz, stereo, fltp, 80 kb/s

Command i tried to dump the metadata:
ffmpeg -i alternativlos-30.ogg -f ffmetadata metadata.txt

Now the file "metadata.txt" should contain the metadata information. But it is nearly empty. Just a header cot printed


cat metadata.txt
;FFMETADATA1


When i try the same thing on a mp3 file. it works.

Reproducible: Always

Steps to Reproduce:

  1. Download file http://alternativlos.cdn.as250.net/alternativlos-30.ogg
  2. ffmpeg -i alternativlos-30.ogg -f ffmetadata metadata.txt
  3. cat metadata.txt

Actual Results:
metadata.txt file contains
;FFMETADATA1

Expected Results:
metadata.txt file contains

In ogg vorbis the metadata is in the vorbis stream while ffmetadata has no streams.
You can copy stream metadata to global by using "-map_metadata 0:s"

I tried to use your suggestion, but i could not get it working. The closest thing i got

ffmpeg -i alternativlos-30.ogg -map 0:0 -map 0:1 -c:a:0 vorbis -b:a:0 128k -ar 44100 -c:v png -strict -2 test.ogg

Stream mapping:

Stream #0:0 -> #0:0 (vorbis -> vorbis)
Stream #0:1 -> #0:1 (png -> png)

Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted
Conversion failed!

You're trying to transcode cover art (jpg/png/etc), which is currently not supported by the ogg muxer (Only theora video is). Notice the "[ogg @ 0x659920] Unsupported codec id in stream 1" error.
Also, you should use the libvorbis encoder instead of the native vorbis one. See https://trac.ffmpeg.org/wiki/Encode/HighQualityAudio for tips.

Are you sure following command line doesn't work as intended?
ffmpeg -i alternativlos-30.ogg -map_metadata 0:s -f ffmetadata metadata.txt

Your provided command dumps the data to the metadata.txt file. Very nice! I just thought i should try it with conversion of the whole file.

Does this resolve the ticket or does some issue remain ?
