How to *absolutely* not transcode

[acki]

Hi all,

I have an android tv box receiver that can handle pretty much all audio/video formats, but still can't get UMS to stop transcoding every now and then.

This is my custom renderer:

Code: Select all

SeekByTime = true
TranscodeAudio = false
TranscodeVideo = false
MuxDTSToMpeg = false
#MaxVideoBitrateMbps = 50
#TranscodedVideoFileSize = -1
StreamExtensions = asf,wmv,avi,divx,mp4,m4v,mov,3gp,3g2,mkv,ts,trp,tp,mts,m2ts,vob,mpg,mpeg,mp3,jpg,jpeg,jpe,jps,mpo
AutoExifRotate = true

Everytime time I add a video feed to WEB.conf and try to watch it, UMS starts transcoding no matter what

Suggestions?

Thanks.

Same problem!
Is it possible to disable transcoding or change settings/bitrate for web streaming (for links located in WEB.conf)?
Pls help!

Just found the solution!

Just add this

Code: Select all

CustomFFmpegOptions = -c copy

to "Yourrenderer.conf" ( in my case /ums/renderers/Sony-PlayStation3.conf ) and Transcode by FFmpeg web .
Thus ffmpeg just receives stream and sends it as is without transcoding!
Now I can watch HD IPTV on my PS3!!!
Hope this will help!

Thx for the tip. I'm also one of the supporters for "non video transcoding at all" movement and I'll surely try it
Thanks!

If you will create correct renderer.conf file where you will correctly define supported files, UMS week stop transcode files.
In your case you incorrectly used some properties like TranscodeVideo or TranscodeAudio which are not definitely booleans.

Looking to avoid transcoding web.conf videostreams as well if codecs supported. What will be the proper container format for rtsp or http streams to enter into the renderer config as f: value?
TIA, Wolf

It doesn't matter if the media is streamed with http or similar, the container is still the format of the media and has nothing to do with the transport.

Regarding using CustomFFmpegOptions to skip transcoding it's really not a good solution. I should be easy enough to make a renderer configuration that streams all, if mediainfo = false, StreamExtensions should be effective. I don't remember if * is supported, but it's worth a try (StreamExtensions = *).

In any case, the proper solution is to create a renderer profile with mediainfo = true and the proper "supported" lines. Video's will external subtitles will be still be transcoded though, since there's no way in the DLNA standard to supply external subtitle files as far as I know. Removing the subtitle files will solve that.

External subs are supported in DLNA and also UMS supports it. If required, check defaultrenderer.conf file as every other renderer supports different ways how external subs must be sent to renderer (like some Samsung models).

Ok, I didn't know. How come I've read several places that videos with external subtitles will always be transcoded then? Is it simply because so few renderers support this, or is it some other reason?

Many renderers support soft subtitles, they travel as a separate stream along video and audio, the renderer takes care of presenting them onscreen or not, and may allow the user choose the font, color, format and even adjust sync timing.
