Subject: Added new feature to enable videos to be recompressed.
X-Git-Url: http://git.pippins.net/embedvideo/static/%27%20.%20%24this-%3Ephpgw_js_url%20.%20%27/jscalendar/%3C?a=commitdiff_plain;h=9990cf64d87333417ab72d6e106fa53df6ad2943;p=videoscripts%2F.git

Added new feature to enable videos to be recompressed.
Changed behavior of script to put single videos into mkv file too.
