You can do this with avconv (or ffmpeg, the syntax is identical). From the command line:
avconv -i input_file -c copy output.ogg
This will copy all the streams, no re-encoding is done. Alternatively, if you have separate video & audio
avconv -i input_video -i input_audio -c copy output.ogg
I'm not sure if the ogg container can contain raw video, you might need to use mkv or avi. Also, there's no reason to use actually raw video or audio (if that's what you really have) for archiving purposes; there are lossless codecs, which will reduce your filesize without losing any quality.
avconv -i input_video -i input_audio -c:a flac -c:v huffyuv output.mkv
You can also use lossless h.264 with
avconv -i input_video -i input_audio -c:a flac -c:v libx264 -crf 0 -preset ultrafast output.mkv
Or 'visually lossless' h.264 with
avconv -i input_video -i input_audio -c:a flac -c:v libx264 -crf 18 -preset ultrafast output.mkv
The x264 presets are: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower and veryslow; the slower presets give smaller filesizes, at the expense of longer encoding time.
