750,ffmpeg looses OGG-theora metadata tags (like title author etc) on OGG->OGG,RyszardG,,"I can transcode one ogg to second with adding tags:

ffmpeg  -i recRLBM.ogv -metadata TITLE=""My title"" -metadata ARTIST=""Me"" output.ogv

Tags are correctly added (what can I see when I run any video player and open output.ogv). But when I run ffmpeg:

ffmpeg -i output.ogv something.ogv

I don't have these metadata informations displayed on the Input #0:
