He there,
I have a vu+duo2 and i am looking for a transcoding plugin with more options than the original one. For example i would like to change the output to be in RTMP format and not to be limited to only 720p transcoding.
Any help will be very appreciated!
Thanks!

Transcoding software and plugin are developed by Vu+ directly. Ask them via www.vuplus.com your needs.

You mean, that third party transcoding plugin is not possible to be made?
I doubt!

You can doubt anything but the reality is that Vu+ known the Transcoding software parth and their options because the Vu+ Dev Team develops directly that part (kernel, driver and Enigma2 parts).

I'm not sure about the RTMP format but I've made a couple of changes / enhancements in the transcoding setup plugin to get more out of the Vu+ Duo2 transcoder.
I've attached the file if you are interested.
Changes:
- I've changed 576p to 720x576 (to be treated as a custom resolution so parameters like 'refreshrate', 'width', 'height' can take effect)
- I've added resolution 960x540 (which is 1920x1080 / 2, great if you need to stream HD over 3G with limited bandwidth)
- Set "refreshrate" from "framerate" (this is used by all custom resolutions, not for 480p, 576p, 720p)
- Renamed "gopframe" to "gopframeb" (I think this is a typo in the original VU+ plugin, it allow us to set the essential number of B-frames in the h.264 transcoder)

If you compare with the original plugin you have on your box (/usr/lib/enigma2/python/Plugins/SystemPlugins/TransCodingSetup/plugin.py) you'll see the differences.

For reference, these are my transcoder settings:

Thats great! Thanks, i will take a look.
But is there anyone who can enlight me, does the transcoding chip inside the VU+duo2 support RTMP format output?

Hi, thank you for the mod.

Just one thing you only have one choice of codec in your file:

if fileExists( getProcPath(encoder, "videocodec") ):
choice = TconfigSelection(encoder, default = "h264", choices = [ ("h264", _("h264")) ] )
setAttr("videocodec", encoder, choice)

Will it support the others that you mention: mpeg2 mpeg4p2 ?

if fileExists( getProcPath(encoder, "videocodec") ):
choice = TconfigSelection(encoder, default = "h264", choices = [ ("h264", _("h264")) , ("mpeg2", _("mpeg2")) , ("mpeg4p2", _("mpeg4p2")) ] )
setAttr("videocodec", encoder, choice)

I did try this and although you get a selection on the Plugin when you goto the webif interfce and click on the transcodeder Icon I only get Audio.

I am trying to get MPEG2 as my WD TV Live will play this format.

Useful info :)

UPDATE: My WDTV Live now plays the file when set to Mpeg2 - but VLC or windows media player doesn't play these :)

I guess I will have to tweak the settings to get the best output.

Thanks again :)

The plugin is maintained by the VU+ team, I only made a few changes to it.
By now this version of the plugin is probably outdated so you should use the latest version that comes with your image instead.
