[SOLVED] Transcode to 720p

Hey everyone,
I'm using UMS 6.5.2 since one month and it is wonderful
But I have one problem with it:
I only stream to my tablet which has a native resolution of 720p so I would like to transcode the videos to this resolution. In the resolution settings I tried to set the width and height in the MEncoder plugin and set it as primary plugin but this does not work. I also tried to add
Code: Select all
OverrideFFmpegVideoFilter = scale=1280:720
to the renderer file but this also does not change the resolution. Any ideas why? I do not exactly know if FFmpeg or MEncoder is used for my stream. I'm using VLC on my Tablet which is recognized as VLC for Desktop from UMS. Most files I'm streaming are: wmv, mp4 and mkv files. Would be great if you can help me with this.
Greetings,
Cilenco

Hi,
Information taken from your
DefaultRenderer.conf file:
# The maximum width and height supported by the renderer. 0 means unlimited.
# Both must be 0, or both must be higher than 0.
# Defaults: 1920 and 1080
MaxVideoWidth =
MaxVideoHeight =
Just add these 2 lines in your renderer configuration file:
Code: Select all
MaxVideoWidth = 1280
MaxVideoHeight = 720

Thank you for this but it also does not work.
For "debuging" I tried with 1024x768 (4:3) as resolution but the video is played as 16:9
EDIT: I found out with OverrideFFmpegVideoFilter = scale=1024:768 it works for some (but not all) videos

You should remove your settings and add the following lines into your renderer configuration file:
Code: Select all
MaxVideoWidth = 1280
MaxVideoHeight = 720
KeepAspectRatio = true
KeepAspectRatioTranscoding = true
Are you using a Samsung Note tablet ? Which model ?

With remove your settings you mean my added lines from my renderer.conf?

Yes.
I asked you that because the Samsung Galaxy Note 10.1 that i checked have a resolution of 2560 x 1600 Pixels, so i was wondering...
EDIT: The 2014 model that i just checked have a resolution of 2560 x 1600.

Yes you are right don't know why I thought so... Sorry for this convenience.
But my WIFI connection is not the best so anyway it would be great to downscale the videos.
I think the lines did it
I tested with the VLC player on my computer and from the codec information I get that the resolution of the stream is now 1280x720.
If this helps to reduce buffering while watching can only tell the time. Or is there something else I could reduce (Bitrate or something like this) to get a better experience?
Already, thank you very much for your help.

You are welcome
Please, add [SOLVED] in front of the title of you first post, as i did in my post now.
Set your resolution to 720 will also use much more CPU power, so the final choice is your.
Maybe you should try something like this:
Code: Select all
CustomFFmpegOptions = -async 1 -fflags +genpts -c:a libmp3lame -ac 2 -b:v 35000k -bufsize 35000k -f matroska
