No video hardware acceleration on my Lenovo Tab 2 A10-70 tablet?


Recommended Posts

I have a Lenovo Tab 2 A10-70F running Android 5.0.1.

 

I am trying to play x265 videos from the internal storage.

 

MX Player shows "HW decoder not supported" and "HW+ decoder not supported."

 

VLC shows "Hardware acceleration error, switching to software decoding."

 

KMPlayer shows "An error occurred with hardware acceleration."

 

Software decoding in all of the above apps is too slow, the quality/frame rate un-watchable.

There is a pretty big difference between "no hardware acceleration" and "no hardware acceleration for x.265" to my knowledge.  I can't say if it'll help, but you might want to try an older format.

While I don't know the definite answer, could it be down to the CPU? I did a bit of research and it turns out that it is not really well equipped for 4K video, as it doesn't seem to have encoding/decoding support for anything greater than 1080p, nor does it support API's such as OpenGL.

I believe the Mediatek MT8165 SoC inside your tablet doesn't support hardware deciding of x265 content.

 

x265 is still up and coming and is not really supported by a lot of hardware at the moment.

It uses a Mali T760 from what I saw, but I couldn't find any info about what video decoding that does.  http://www.arm.com/products/multimedia/mali-gpu/high-performance/mali-t760.php

Some claim it uses a PowerVR chipset with a lower power proc, but my device does not seem to.

You're right :) I wonder if there's a way to get good performance via. the CPU?

x265 is an open source free software and library for encoding video using the High Efficiency Video Coding (HEVC/H.265) standard.

 

It doesn't mean 4k video.

To be frank, good performance and Mediatek dont usually work together. Part of the problem is Mediatek doesnt release the kernel source, not even to OEMs, and sources that are available are in strange formats and you have to jump through hoops to get them.

 

You could try rooting it, so that you can use a program to change the governor to more of a performance mode.

 

Have you tried other video files? It is possible your device does support encoding via HW, but in this case the issue might have to do with which x265 profile the video was encoded with.

 

I also read that, the chipset manufacturer needs to support HEVC, until then HW and HW+ decoding wont work with x265. I have no idea if Mediatek supports this on your model. I would try using handbrake to convert your file from x265 to x264 and see if it works better.

    • You've tried DuckDuckGo and Brave Search, now get serious with SearXNG by Paul Hill Over the last decade, it has become quite trendy to dump Google Search in favor of privacy-preserving alternatives such as DuckDuckGo, Startpage, and Brave Search. These search engines have done a very good job at highlighting dodgy practices by Google, such as adjusting search results based on what it thinks you’ll like (filter bubble) and stalking you around the web to advertise to you. While these search engines are good starting points when compared to non-private services like Google, there are still quite a few issues with them. For example, both DuckDuckGo and Brave Search require running non-free JavaScript in your web browser, which is comparable to running proprietary software on your computer, meaning you can be sure about what it’s actually doing in the background. Another issue is that these search engines are hosted on the respective companies’ servers, and you are using a service that you don’t control. Finally, DuckDuckGo, while offering privacy features, relies heavily on Microsoft’s infrastructure for its results and, in the past, has permitted Microsoft tracking scripts. If you are looking for a more private search solution than DuckDuckGo, Brave Search, and Startpage, then I recommend taking a look at SearXNG. It is a privacy-respecting metasearch engine that can be used via different public instances, which is useful for mobile users, or you can install it on your computer or server and run it locally with maximum control. Unlike Google, Bing, or Brave Search, which crawl the web and have their own search indexes, SearXNG is a metasearch engine, meaning it taps other search engines, stripping your identifying data, such as IP address, user agent, and cookies, in the process. Your search query is sent to the other search engines you enable before aggregating the results. SearXNG has deployment flexibility. If you are a casual user or a mobile user and don’t want to run SearXNG locally, you can use a public instance that is hosted by someone else. The main problem with this is that you are putting trust in the maintainer of the instance regarding stuff like logs that they may keep; good hosts should have a privacy policy explaining their policies. If you are trying to use SearXNG, you can also install the software on your device and then head to 127.0.0.1:8080 in your browser and search from there. While you don’t have to worry about a third-party admin like the public instances, search engines could ultimately block your IP address if they frown on you pulling in their search results locally. If you want to run it locally, it’s a good idea to use proxies or VPNs to hide your actual IP. You don’t have to worry about this with a public instance, as search engines never see your IP address. The main privacy benefit of using SearXNG is that it isolates your identity from the underlying engines that it’s capable of searching, such as Google and Bing. These search engines will only see requests coming from a generic server, so they can’t profile you and create a bubble filter that influences what results you see. This also ensures that your search engine doesn’t turn into an echo chamber that prevents you from reading alternative points of view. As a free software project, you are allowed to inspect SearXNG to make sure there are no negative features bundled inside. This sets it apart from the privacy search engines mentioned earlier because you can’t check their source code. As a meta search engine, you are not restricted to getting results from one source. Due to the fact that it scrapes content from other websites, your SearXNG instance will periodically get blocked from different providers, so it’s good to select a range of sources as a backup. While enabling all of the services will give you great results, this can make searching slower. I am personally happy with slower searches for the best results, but you can always check which providers are slowing down your search from the search results page and disable them to speed things up. If you want decent results quickly, enable the main search providers such as Google, Brave, DuckDuckGo, Qwant, Bing, and Yahoo. This way, you get wide coverage without the latency. On the Engines tab in Preferences, do note that there are different tabs, such as General, Images, and Videos, with their own providers that can be toggled and are not covered by "Enable all" while on the General tab, so be sure to dig into each. Just a note, if you want to enable everything, press "Enable all" in one tab, then hit save at the bottom of the page, then do the next tab, and so on. If you press "Enable all", then do that in each tab, and then save, nothing will stick. When I had just some of the search engines enabled, I searched “define nefarious” and results came back with the definition of “define” - obviously that was a sucky result. However, when I had everything enabled, it found dictionary pages for the word “nefarious” and even had an inline definition on the sidebar, which is quite nice too - that was delivered by WolframAlpha for anyone wondering! Probably the worst thing about this meta search engine is that the engines you select are saved with a cookie, so you must enable them on every new device you use SearXNG on, including if you decide to go into incognito mode with your web browser. Honestly, I would say this is the most annoying aspect, and perhaps if your browser lets you choose a separate private browsing search engine, then it would be best to use DuckDuckGo for this portion of your browsing. Another weakness of SearXNG is the random blocking of it by search providers. When you are on the results page, expand the “Response time” box, and it will show things like “Suspended: too many requests” or “access denied”. This is why it is good to enable several providers so that there is always a fallback to get results from. I won’t pretend SearXNG will be for everyone, however, if you enable all of the providers and put up with the slower response time, the results can be really amazing. Even if you don’t want to use it as your daily driver, keeping a bookmark handy that links to it is a good idea if you ever feel like doing a deep dive into a niche topic where other search engines are just failing to bring up any good result, due to the amount of sources it looks on. If you’re interested in radical user control over the software you use, installing SearXNG locally can also be a good idea, but be prepared to be temporarily blocked from sites if you trigger bot sensors without a VPN. Personally, I’ve opted to use a public instance, rather than install it myself. If you want to use it via a public instance, head over to searx.space to find a provider. Let us know in the comments if you have used SearXNG or its predecessor, Searx. What do you think about the quality of the results?
    • Dear Neowin, If it is not too much trouble, can you start using the new-ish designations for Insider Preview? "Experimental" is different than "former Dev" as it can apply to different models, eg 26H1 or 26H2 etc, right? No need to seed confusion IMHO. And, please "finally" update your graphics. OK?
    • Did you see their FAQ, its quite good. Have a look in the Advanced section. https://delta.chat/en/help
    • Just install Linux Mint that is a real blessing and many times cheaper because you can continue using your old Windows computer/laptop with the latest Linux updates.
    • Interesting share -- however it does not make sense: Email messages get stored somewhere, so how is Delta Chat "based on email" and decentralized without actually storing anything? By Web3 standard practices, the various Relays would require dedicated storage to make messages available to the recipients (like a large series of message queue channels, akin to racks of traditional post office boxes)... and Contacts must be two-way confirmed in order for encryption keys to be exchanged (ostensibly every key-pair is uniquely bound between sender and recipient) and the Relays would preserve the public keys in order to facilitate message carriage... or every device stores all sorts of keys and contact info. All of this to say, decentralized messaging is like running Bluesky nodes except instead of discovering/browsing public feeds by various posters (at the given node) these Delta Chats would be relaying encrypted messages (via Relays) that only trusted recipients would have the appropriate decryption key (their own private key) to read it. But this doesn't solve the "it's like email" sales pitch. The only way it's like email is that there's encrypted binary stuff being transported from your app into the federated ether of Delta Chat Relays for others to decrypt (hopefully only the intended recipient)... but outside of this federated relays framework, it is absolutely nothing like email.
