whats new in bttvgrab 0.15.0
----------------------------
- really much - I think I have missed something
- X display - select the apropriate color mode for your display, use
the -m flag of bttvconvert to set the playback speed
- conversion - now any file format supported for reading can be
converted to any of the output formats (including mpeg)
- new input/output module - in/output is modularized, other output
methods will follow soon (e.g., FTP), file names are specified
as URLs (but FTP and HTTP are not yet supported)
- networking - bttvgrab or bttvconvert can operate as a grab server,
currently with a limit of 1 connection, bttvconvert can read its
input files from such a server
- webcam changes: webcam mode is enabled by specifying a webcam: URL
(like "-f webcam:/tmp/bttvgrab/"), the webcam script was enhanced
as well
- better NTSC support: specify -N NTSC on the bttvconvert commandline
to get 30fps mpegs
- many bugfixes, Makefile/configuration issues, and more
- many new bugs, I bet ;-)
