In general, you can forget about fast rewind--it is prohibitively hard
to do with temporally compressed codecs.  And presumably you'll either
have to open the files yourself, or use some third-party API for
working with container formats.  (for example, if you're saving h264
to an mp4 container, you could use mp4v2 or ffmpeg)

You could also save raw h264 to disk (raw bytestream), but there
typically isn't timing information present, so it is unsuitable for
playback applications.

For H264 and G711, your best bet is an AVI container.  G711 is not a
standard part of the MP4 container format, AFAIK.  I'm not sure about
newer containers like matroska.
