Great update.
Seems like the item rulers are still affected by project time offsets though. I would assume there is no use case for this, the item time ruler should always start at zero...right?

Will this eventually also include hardware video decoding (vlc)?

Is there a fix in sight for the Melodyne ARA2 issue where edits are lost when performing an undo in Reaper (as opposed to an undo in Melodyne)?

Has this been mentioned in any of the "dev" versions ? If not there is no chance to see it in an "rc".

The VLC Player itself features hardware decoding. But Reaper doesn’t seem to make use of it, when VLC is used as video decoder.

It means it is using the GPU for playback not the CPU, which results in significantly less CPU usage. It's also exactly what the GPU is designed for so it is much more efficient than the CPU for video.

+1 This would be great. Currently I'm experiencing glitches with video playback using VLC and FFMPEG. It seems that about every 3-5 seconds the video playback gets stuck on one frame then continues. The playhead also has the same problem. I believe this is due to the video being processed by the CPU instead the GPU. WHen playing the same video in VLC stand alone playback is smooth.

What exactly do you think the GPU can do. I am not an expert for this at all, but I doubt that the GPU is able to do MPEG decoding, (What it can do is font rendering and ray tracing, but this does not help with Video.)

Yes the GPU can do decoding/encoding of video... https://developer.nvidia.com/nvidia-video-codec-sdk

Yes and the strange part is, that Reaper doesn’t take advantage, although VLC supports it.

It's not really strange, VLC isn't really designed to be loaded by other applications, the way we use it for decoding is by (primarily) loading its copy of libav...

If you don't know much about it, do your homework and then comment about whether it may or may not be useful.

Hint 1: It would be extremely useful.

Hint 2: Yes, GPUs can decode MPEG along with several other formats

What about FFMPEG? That should be able to support it, yes?

Not sure what legwork the calling application has to do in order to enable it.

Thanks Justin for the insights, some of us were wondering why this didn’t work.

@Justin, not sure if you want to invest time for it (would however be highly appreciated by a bunch of users!).
But here’s a link that might give you some info for ffmpeg:

Justin thank you for taking a look into this. I think we really would benefit from having some aspects of Reaper run on the GPU.

I realize this may be a difficulty process to develope a video engine that works in this way so I totally understand if this needs to wait until after Reaper v6 is out. In all fairness I would much rather see envelopes in the MIDI editor fully worked out in v6 before graphics acceleration.

Here is what I'm experiencing on the video side:

There does not seem to be anything with in the Reaper preferences that stops the glitches I'm experiencing on multiple test rigs. It also doesn't seem to matter what brand GPU the rig is using. Video playback is stuttered in both VLC and FFMPEG. Quicktime codec playback seems to be unsuable, it stutters so much that I can't write music in sync with the video. VLC seems to be the most stable but it still stutters about every 4-5 seconds.

Is there anything us users can do to help test a dev version of Reaper that allows the video to be playback on the GPU instead of the CPU? Is there any open source access that can be extended to us scripters. If so perhapse we can help with heavy lifting that's likely required to develope such an engine.

Thanks again for all the hard work with the most recent updates. You guys are the real deal and we are lucky to have you.

(I did not say that this would not be useful or desirable...)

I do know that the "GPU" Processor on a video "card" can do jut about anything, because it in fact is a "processor", and as it does have special features there are things (like calculating bitcoins) it can do especially well. But OTOH to make use of this you need to do software for that exact GPU your hardware features, and this of course is not what a "general purpose" software such as Reaper can be expected to feature. Regarding a video codec, this needs to be done in an appropriate driver software. If there is such a driver that adheres to the standard video codec format Reaper uses, it should be usable by Reaper (but this does not seem to have been discussed here but the discussion was on "Reaper using hardware", which in it's literal sense is not viable, useful or desirable... ).

I am happy to have learned by Dragon and you that there in fact are video codec algorithms to be run on the GPU and by Justin, why Reaper can't make use of that yet.

-Michael

As long as we all keep learning. Otherwise, we're screwed

Sorry if I came across as overly harsh.
