media-video/ffmpeg-1.2.6-r1 - ffmpeg fails to dump vorbis metadata

[schorsch_76]

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 the ffmetadata format.

Please see the gentoo bug tracker too.

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

[schorsch_76]

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 ?

[schorsch_76]

I guess this resolves this issue

[Michael Niedermayer]

ok, closing it then
