VideoHelp Forum. Remember Me? Download free trial! Results 1 to 5 of 5. I'm hoping someone here can help me out. I was gone on vacation for about a week and upon returning home it seems the video acceleration on Youtube stopped working on my computer, most likely through some combination of updates that went through while I was away.
Prior to this videos had been playing very smoothly and I would watch youtube videos at p 60fps without issue on Firefox. Now when attempting to do the same thing it drops almost every frame and the performance tab in task manager shows my GPU not being utilized and my CPU maxed out.
I've looked at DXVA stats during playback as well which confirm the data presented by task manager. The same video plays back fine in the microsoft Edge browser.
Hardware video acceleration
I've attempted to use the hify plugin with Firefox but have not had any luck. Does anyone know if there was a recent Firefox or Windows update that may have thrown a wrench in my youtube video decoding, and more importantly how I might be able to fix it? Any thoughts would be greatly appreciated. Thank you. Which GPU? Which Firefox version?
Make a screenshot. GPU is listed on system specs under my username. Here are my stats for nerds screenshots.

Well it looks like Firefox did an update yesterday that fixed things. Thank you for offering up some suggestions. Replies: 66 Last Post: 5th Sep My youtube video look too bright!

The company grants free usage of its own related patents based on reciprocity, i. Mozilla added VP9 support to Firefox in March In an updated version of the WebM format was published, featuring support for VP9 together with Opus audio. In Marchthe MPEG Licensing Administration dropped an announced assertion of disputed patent claims against VP8 and its successors after the United States Department of Justice started to investigate whether it was acting to unfairly stifle competition.
Throughout, Google has worked with hardware vendors to get VP9 support into silicon. In April Google released a significant update to its libvpx library, with version 1. VP9 support was added to Microsoft's web browser Edge. In MarchIttiam announced the completion of a project to enhance the encoding speed of libvpx. VP9 is customized for video resolutions greater than p such as UHD and also enables lossless compression.
The VP9 format supports the following color spaces : Rec.
An early comparison that took varying encoding speed into account showed x to narrowly beat libvpx at the very highest quality slowest encoding whereas libvpx was superior at any other encoding speed, by SSIM. Another decoder comparison indicated 10—40 percent higher CPU load than H. VP9 offers the following 14 levels: . VP9 is a traditional block-based transform coding format.
The bitstream format is relatively simple compared to formats that offer similar bitrate efficiency like HEVC. VP9 has many design improvements compared to VP8.

This is especially useful with high-resolution video. In order to enable some parallel processing of frames, video frames can be split along coding unit boundaries into up to four rows of to pixels wide evenly spaced tiles with each tile column coded independently.
This is mandatory for video resolutions in excess of pixels. A tile header contains the tile size in bytes so decoders can skip ahead and decode each tile row in a separate thread. Subunits are coded in raster scan order: left to right, top to bottom. Starting from each key frame, decoders keep 8 frames buffered to be used as reference frames or to be shown later.The comparison evaluated the slowest encoding speeds available for each encoder.

Some of these are known to have fixed function hardware, but this list also incorporates GPU or DSP based implementations — software implementations on non-CPU hardware. The latter category also serve the purpose of offloading the CPU, but power efficiency is not as good as the fixed function hardware more comparable to well optimized SIMD aware software.

VP9 has many design improvements compared to VP8. This is especially useful with high-resolution video. Also the prediction of motion vectors was improved. In order to enable some parallel processing of frames, video frames can be split along coding unit boundaries into up to four rows of to pixels wide evenly spaced tiles with each tile column coded independently.
This is mandatory for video resolutions in excess of pixels. A tile header contains the tile size in bytes so decoders can skip ahead and decode each tile row in a separate thread. Subunits are coded in raster scan order: left to right, top to bottom. Starting from each key frame, decoders keep 8 frames buffered to be used as reference frames or to be shown later. Transmitted frames signal which buffer to overwrite and can optionally be decoded into one of the buffers without being shown.
The encoder can send a minimal frame that just triggers one of the buffers to be displayed "skip frame". Each inter frame can reference up to three of the buffered frames for temporal prediction. Up to two of those reference frames can be used in each coding block to calculate a sample data prediction, using spatially displaced motion compensation content from a reference frame or an average of content from two reference frames "compound prediction mode".
The ideally small remaining difference delta encoding from the computed prediction to the actual image content is transformed using a DCT or ADST for edge blocks and quantized. Something like a b-frame can be coded while preserving the original frame order in the bitstream using a structure named superframes.
Hidden alternate reference frames can be packed together with an ordinary inter frame and a skip frame that triggers display of previous hidden altref content from its reference frame buffer right after the accompanying p-frame.

Please ask a new question if you need help. Worth trying without Themes and Extensions enabled, though. Sorry that you haven't received an answer yet. Way beyond my expertise, but I do recommend that you check for updates for your graphics drivers and see if new drivers provide a resolution of your issues.
If the CPU is working so hard, hardware acceleration is most likely off. The whole point of it is to offload video to the GPU, which is more suited for handling the load.

Restart Firefox. If going through the UI doesn't solve it, you might need to Refresh your Firefox settings - this has helped many people who upgraded to Windows 10, dragging along incompatible settings in their Firefox data. I can see I'll keep that in mind about suggesting the bit build, as it seems to solve some issues people are having with Firefox could use hardware based decoding for MP4 if your graphics display this supports, but will have to use software decoding for VP9.

Firefox may have the same problem, too. When YouTube used Flash, it used the H. Videos with this codec usually have the. This is a de facto industry-wide standard beyond just web browsers. While Apple and Microsoft only support H.
Google acquired the VP8 codec and built it into Chrome, and Firefox followed suit. Google is now pushing the next-generation VP9 codec, which is now also built into Chrome and Firefox.
Files using this codec usually have the. While H. The underlying technologies are covered by a wide variety of patents. Cisco is effectively paying the licensing fees and providing a free plug-in for Firefox users. Firefox automatically downloads this plug-in and uses it to enable H.
At the beginning ofGoogle announced it would be removing H. Mozilla was likely holding on for Google to follow through on its promise, but Google never could — instead, Mozilla relented and added H. This means playback takes less CPU time, which means less battery power is wasted and less heat is generated. Really, all modern pieces of hardware support H. This includes all types of smartphones, tablets, PCs, Macs, and even Chromebooks.
When a web browser — yes, even Chrome — plays H. Even Adobe Flash supported hardware acceleration of H. But there is no hardware out there that will accelerate VP8 and VP9 videos. But, more than five years later, no devices ever arrived with hardware-accelerated VP8 decoding. That just encourages Mac users to use Safari instead. On devices with particularly slow CPUs, videos may even stutter instead of playing back smoothly.
To get more efficient playback, you could just switch to Safari, Microsoft Edge, or Internet Explorer.

The important thing to look for is to the right of each of these items. Some might read Software only. Hardware acceleration disabledbut that's fine. If all or most of your values are set to disabled then you should read on to find out how to turn hardware acceleration on. If you see that the "Use hardware acceleration when available" option is already enabled but your GPU settings show that acceleration is unavailable, follow the next step.
If they still show up as being disabled, it could signal a problem with your graphics card or the drivers for your graphics card. Update the drivers on your computer to resolve these problems. Turning off hardware acceleration in Chrome is as easy as repeating the above steps for turning it on, but removing the option instead of enabling it. See whether hardware acceleration works better on or off.
The site is provided by Mozilla who are the people behind the Firefox web browser, but the tests work equally well in Chrome. The page provides a number of links which will show how well your browser performs. For example, a very simple demo is provided by this animated blobbut there are further examples including these draggable videos and this 3D Rubik's Cube.
Also, try watching high-definition videos on YouTube and make sure the video is crystal clear. Hardware acceleration can't help with buffering. However, you might find that other features of Chrome perform far better than before. Browsers Chrome Safari Firefox Microsoft. Tweet Share Email.
