Re: Linux - Recommendations for GPU to transcode and stream

Thank you for the response, you give me hope! I will also consider the notes at http://www.remlab.net/op/vlc-vdpau.shtml. I will plug the NVidia GT 640 card back into the test server and work on building VLC 2.2 and libav 10. I am assuming the 1-click installation of the OpenSuse 13.1 nVidia driver ...

Re: Linux - Recommendations for GPU to transcode and stream

I've installed an AMD/ATI 7730 GPU in the same OpenSuse 13.1 based Dell Poweredge 1950 server and installed the AMD proprietary driver. I can't see that VLC is taking advantage of the GPU during the transcoding. What am I missing? Would I have better results by testing a VLC 2.2 build?

Re: Linux - Recommendations for GPU to transcode and stream

On the test server, the nVidia-settings utility shows GPU usage. If I use VLC to display a stream the usage goes up to 10%, good. If I ask VLC to transcode the stream, the nVidia GPU usage never changes from zero percent usage, not so good. Are there settings to get VLC to use the GPU for decode whe...

Re: Linux - Recommendations for GPU to transcode and stream

Is there a way to confirm from the CLI debug output that hardware decoding is actually being used? I have a test platform: a Dell Poweredge 1950 rack server with a Xeon L5240 @ 3.00GHz with a PCIe x8 to x16 adapter into which is inserted an an nVidia GT 640. I intend to test other GPUs to compare. T...

Re: Linux - Recommendations for GPU to transcode and stream

Thank you for the response. The Xeon x5450 does not support Quick Sync Video. I am running Debian Squeeze on the i7-3770k machines, and had tried to get the nVidia hardware enabled on it but had trouble. I will give a more modern Debian release a try, both on the x5450 and the i7-3770k. I also have ...

Linux - Recommendations for GPU to transcode and stream

I've had fairly good luck using Debian Linux, VLC, x264 and a i7-3770k to groom and stream some satellite video feeds. One machine is processing two mpeg2 HD channels to mpeg4 in real time. That system is documented in earlier postings on this forum. I'd like to use an older Xeon x5450 multicore ser...

Grooming satellite video streams for recording on an Amino 5

I want to share my experience with using VLC/x264 as a "video transrater" and look for some help tuning its performance. As I'm using the word, a transrater is a box that adjusts the bandwidth of a video stream. APPLICATION : distributing satellite network HD video streams to a group of Am...

Re: VLC Set top Box

Amino 130/125 can be tuned to a mpeg2 udp transport stream. If VLC is streaming content to the multicast 239.0.0.2:1234; pointing the web browser to igmp://239.0.0.2:1234 will issue an igmp join and tune the STB to the stream.You can see that watching a wireshark packet capture. If you get an accoun...
