Re: rtranscode 4.0 - Current state of development

Unfortunately those patches never made it into the upstream gstreamer development and with gstreamer-omx-1.10 software scaling has to be used and this is heavy work for the CPU, especially for HD streams, and limits what can be done. Transcoding will never be as effective on Stretch as it was on Je...

Re: Tutorial: Compile VLC with HW acceleration - Stretch, RPi 2/3

With the GPU running a 500MHz omxplayer can play up to 1080p60. This doesn't work with with VLC. But all of my 1080i50 recorded (or live) TV streams work well with VLC.

Hello, I have a problem. Today I've got my brand new RPi3 and Samsung Evo Plus 64GB microSD card. After installing a fresh Raspbian Stretch on the SD Card I came to that topic and followed all the steps. So far so good.

Re: Convert movie audio on the fly

Thank you for your answer gkreidl :) Yep, RPi will be connected with HDMI to the TV and I want to stream the video from my NAS (with USB connected to the Router) Is that also possible with omxplayer? Yes. By default omxplayer converts audio to 2 channel PCM. You can also activate passthrough, to se...

Re: Convert movie audio on the fly

I assume you want to play the video using the RPi. omxplayer will convert audio on the fly, if your TV doesn't support a format.

rtranscode 4.0 - Current state of development

rtranscode 4.0 will run on both Jessie and Stretch (and even on Wheezy, I suppose), but there is a huge difference. gstreamer-omx-1.0 for the RPI included a lot of patches (30!), which did not only fix bugs but implemented scaling the decoded image using the GPU (Patches 1, 11 and 14). Unfortunately...

Re: GStreamer and omx encoding from live source.. a naive problem

Problem solved. I let it run for about 90 minutes and memory usage didn't grow any more.

Thank you, 6by9!

An updated package for testing is available from gstreamer1.0-omx-rpi_1.10.5-2+rpi+patches_armhf.deb

Nginx is good for reverse proxy. I don't thing lighttpd can do that.
Of course it can: https://redmine.lighttpd.net/projects/1 ... s_ModProxy

I'm using it for almost a decade now.

Re: Alternatives to omxplayer

It can't work. Simple mathematics: Multiply width x height x fps x 32 (RGBA to bits) and compare that with the 100 MBit ethernet bandwidth.

If your projector can take it (different frame rates and video resolutions), you an use omxplayer with the '-r' option.

Re: Possible to downgrade back to Jessie 8 ?

No, downgrading is not possible. You have to start with a new OS on SD card. But that's really simple: Download the image zip file (don't unzip it). Get Etcher. Insert the SD card. Start Etcher, select the image file, select the SD card and run it. Etcher does a bit by bit comparison after flashing ...
