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 Metadata: ALBUM : Alternativlos ARTIST : Frank+Fefe COMMENT : Alternativlos 30 über SIGINT, Kryptographie und die NSA GENRE : Speech TITLE : Alternativlos, Folge 30 DATE : 2013 track : 30 METADATA_BLOCK_PICTURE: AAAAAwAAAAlpbWFnZS9wbmcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAfp6JUE5HDQoaCgAAAA1JSERSAAACCQAAAesQAgAAAJr0RfgAACAASURBVHgB7L1tkJXVuaevMzFUjYiipIqXKulORdpMRJsGTx1NYndrxWRGGgStMRIjiK9TdYII8Xw6kW4931RazKkxaBTRiJ4pRegmM5nkQHeTlKYqvClOTcD87SZVNlSNCgpOlfHD+afXz1SWZ7u393r ------------------ 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.
