Big thanks to you fellas, Popcornmix and fernetmenta.
This might just well be the snowflake that starts the avalanche
Id love to help out, but its well beyond my coding ability.
Maybe look at how mpvplayer implemented their playback? https://github.com/mpv-player/mpv

I am about to move audio sync from player to audio engine (http://forum.kodi.tv/showthread.php?tid=237842) . After this has been completed the controlled system will be much easier to handle. Measuring the error after the resampler removes the need for a derivative term for the controller (which we don't have at the moment)

From David Pogue's review of the new TiVo Bolt:
Quote:You can now play back shows at 1.3 times their actual speed, too, without affecting the pitch of the audio. (You hit the Play and then Select buttons on the remote to turn this Quick Mode on or off.)The anti-speed-up faction on this thread makes the feature sound like it would be used by only a super-narrow niche of Kodi users, but one of the most popular consumer video companies in the world felt it was important enough to add to their new flagship product... and it got nothing but praise from the pre-eminent consumer product reviewer of our time.
1.3X is a good choice. It gets you through a 60-minute show in 46 minutes without turning the TV characters into chipmunks. The musical tempos are a little faster, and there’s a certain overcaffeinated quality to people who already talk fast. But for sports, awards shows, and Kubrick movies, it’s fantastic.

Apples and oranges. TiVo can easily do this because they have a single codec and video format to support for their recordings. No one has said that it would be a bad thing to add to anything, so of course it will only have praise. It was easy for TiVo to include it, so they did. If it was as hard for them as it was for us, and they were unpaid volunteers, they would tell you the same thing.

Mythtv supports it in all codecs it supports afaik. And has done for years. But yeah their playback code is different (but still based on ffmpeg) so apparently the code is not easily portable to kodi.
I for one would welcome our new speedup overlords.

My point was not about the relative ease or difficulty of implementing this feature in Kodi versus TiVo. It was about the utility of such a feature. Haters imply that adding a speed-up feature to Kodi would be a complete waste of time, but the TiVo product managers sure didn't think so, and neither did Pogue, who described the experience as "fantastic."

I do think it is a waste of time. 3D support is also a waste of time, in my opinion. Yes, we're allowed to have options. Don't get all pissy about it. Not a single negative opinion has any impact on if these features get implemented or not. You can try to convince people otherwise all you want, but it will not have any impact on if a feature is added or not.
By the way, also in my opinion, David Pogue's articles and reviews have been shit for the last 10 years, and TiVo is a failed company that is barely hanging on.
Why are you even bringing this up now that there is a developer interested in the feature, and working on it? Be happy that the feature is coming, and stop caring about what other people think.

I'm new to Kodi and was looking for this exact feature.
Little odd that this isn't an option as it is common in most media players likes vlc, gom, etc...
Hopefully this can be implemented in the near future.

I am very excited for this feature! I watch/ listen between 2x-3x to most talking head videos, audiobooks, and podcasts.
Swift is an app that I use for up to x3 playback
Video Speed Controller is a Chrome plug in for html5 videos goes up to x4
Kaltura is built on open source code, I'm still looking into it, but thought this may be helpful for the developers?

If I could code I'd be right there with you guys.
Cheers!

Funny, AVPlayer in iOS does this perfectly. Even audio is presented in a nice way. I'm seriously impressed. Dial in your desired rate, and it does the magic with zero fuss.

avplayer and avplayerhd are perfect examples on IOS, and ive been using it for years. Shame though they havn't ported the software to android or ms store.
i think the support for this feature is growing within the kodi community, and hopefully with the devs like popcornmix and fernetmenta the feature will be implemented in a version or two!.
Would love an update on it though guys, to see how its been tracking over the last couple months.
Cheers

I have this working quite nicely on my VideoPlayer branch. Means VideoPlayer can go up to 1.5 of normal speed with audio. I have not done the UI part.
RE: Speed up playback watching video (include 1.1x to 1.5x ffwd rate with audio)? - popcornmix - 2015-10-10
I've taken FenerMenta's update and added a GUI setting. It's in latest Milhouse build for Pi.
I believe it is also in Milhouse's latest x86 OpenELEC build.
Use settings/video/playback and change "Accelerated playback speed" from disabled to one of 110%, 120%, 130%, 140%, 150%.
Now when playing a video the first fastforward step will play with sped up audio.

I will use use ffmpeg's atempo filter in the next iteration to avoid chipmunk voices.

@FernetMenta - thank you for this.
