VDR Plugin 'streamdev' Revision History
|
||||
---------------------------------------
|
||||
|
||||
2010-07-20: Version 0.5.0a
|
||||
|
||||
- set externremux.sh executable in distribution archive
|
||||
- externremux quality value should be wlan54, not wlan45
|
||||
|
||||
2010-07-19: Version 0.5.0
|
||||
|
||||
- using SIGINT in externremux to kill mencoder works better than SIGTERM;
|
||||
especially x264 still needs a SIGKILL sometimes
|
||||
- added --remove-destination to cp commands installing plugins
|
||||
- fixed "plugin doesn't honor APIVERSION" (reported by carel@vdrportal)
|
||||
- updated Italian translation (thanks to Diego Pierotto)
|
||||
- config option "client may suspend" hidden if not applicable
|
||||
- updated and enhanced README
|
||||
- separated language resources of client and server
|
||||
- restructured build process
|
||||
- added support for HTTP method HEAD
|
||||
- rewrite of externremux.sh, including support for various URL parameters,
|
||||
logging and improved shutdown
|
||||
- start externremux script in a separate process group
|
||||
- changed HTTP URL path for externremux from EXTERN to EXT (suggested by
|
||||
Rolf Ahrenberg)
|
||||
- HTTP headers now have to be emitted by externremux script
|
||||
- pass channel related information and URL parameters to externremux script
|
||||
through environment
|
||||
- implement CGI like interface for externremux script
|
||||
- dropped "Synchronize EPG" feature. Please use epgsync-plugin instead
|
||||
(available from http://vdr.schmirler.de)
|
||||
- proper tsplay-0.2 patch detection. tsplay-0.1 is no longer recognized

# externremux.sh - sample remux script using mencoder for remuxing.
|

#
|
||||
# Install this script as VDRCONFDIR/plugins/streamdev-server/externremux.sh
|
||||
#
|
||||
# The parameter QUALITY selects the default remux parameters. Adjust
|
||||
# to your needs and point your web browser to http://servername:3000/ext/
|
||||
# To select different remux parameters on the fly, insert a semicolon
|
||||
# followed by the name and value of the requested parameter, e.g:
|
||||
# e.g. http://servername:3000/ext;QUALITY=WLAN11;VBR=512/
|
||||
# The following parameters are recognized:
|
||||
#
|
||||
# PROG actual remux program
|
||||
# VC video codec
|
||||
# VBR video bitrate (kbit)
|
||||
# VOPTS custom video options
|

# WIDTH scale video to width
|

# AC audio codec
