TV Out via 3.5mm Audio

I know it has been asked before over here, but i would like to discuss it again:
Could it be somehow possible to activate TV-Out over the 3.5mm audio connector on the defy?
The Samsung Captivate (aka Galaxy S) has it and the devs managed to support it in their CM7 version for the captivate. Perhaps we could use some of those "drivers"?
It would be just to cool to use the defy with a bluetooth keyboard (apple wireless keyboard working flawlessly btw) and a nice big screen for browsing and writing documents...
Btw the cable looks like this.

i dont think its matter of drivers, if the headphones jack is not wired to give tv output, then it wont be physically possible without a hardware mod... just my opinion, i could be wrong tho...

Indeed. If it's not meant to output video then it's not meant to. End of story ^^

Did anybody proof that its not wired?
At least it can give audio over 3 pins (stereo+mic) - that means all contacts needed are wired. COuld the tv-signal perhaps be "disguised" as audio signal?

Do you really think that motorola would put a video-output capable 3,5mm jack in the phone, and not use it as a feature?? Things aren't free in this world. If there was one, they would have said so, simply because...they could sell more Defys thanks to it.
Putting a really awesome feature in a phone and not saying nothing about it? Come on... xD
In addition our phone isn't event meant for tv-out, forget about having it flowing out of wierd places like an audio jack x)

Do you really think motorola wouldn`t open the bootloader even if they could? They could have sold a few defys more with an open bootloader....
You might have noticed that im not that convinced by your argument.

No **** man. Moto also advertised a gpu less omap 3610. When in all actuality we have omap 3630. Why would they do that? I think this deserves more looking into

I think if it would be possible, chances are that a kernel tweak would be needed to activate it and thus it would not be possible with a locked bootloader.
But still, i think it could be worth it to take a look in the Captivates librarys regarding tv-out.

Motorola wouldn't have significantly more sales if the bootloader was unlocked: over 80% of consumers don't even know what a locked/unlocked bootoader is

Can the hdmi / vga tv out be sent via USB?

Please dont be naif, you know how much motorola lies about the defy!, i did a search about the defy hardware, the chip as you know is an omap3630 with sgx530 and IVA 2 +, this chip is capable of transmit audio and video, see the pic:
b.imagehost.org/0148/tiomap.jpg
So the probem is software related, maybe its too complicated due to the locked bootloader but i think its totally posible, its just a matter to find some device that uses the same chip, like the Droid x or milestone 2...

not really... we all know the chip is capable, but if it is not physically utilized, no amount of software tweaking will make it possible... i dont think they would have bothered to connect the 3.5mm audio jack with video out if they are not going to use it...
but u r asking the right question... think outside the box, if its even remotely possible, i would like to have this feature

Following your argument i would conclude that it MUST be possile to route a video signal through the headphone jack. Of course you would need a software wrapper which codes the video signal and puts it out as a sound. If you would do that as an app, this might be awfully slow. But i cant see a reason for this to be impossile as the headphone jack IS wired to the sound output and apps ARE capale of using that sound output.
I would really like to use an app like that as a workaround, as long as its fast enough for simple rowsing.
Edit: I just searched the marked for "Image to sound" apps and came across "Spectral" which takes an image, converrts it into a sound spectrum and plazs it. It should not e too hard to change the conversion to conformwith the component video standard.
This would still onlz convert one image and i dout it would be possible to use this with screenshots in realtime but it would be a good step towards video out on the defy.

Dude in fact, it is very hard/impossible. One thing is "transform" a digital image in a digital audio. In that case you dont need to make sense, just convert one block of image into one "la" ou "do" and you are good to go.
We have a limited range of frequencies that we can hear and software/hardware generally take advantage of that. Transport analogic video(that may take a broad range of frequencies) trought analogic audio hardware may be impossible for near anything apart form really simple scenes

High-Quality Audio Recording

I have a question for the developers (im not one):
Though the KF doesnt have a built-in mic, it supports an external one for audio recording. Ive been using Android devices for a little over two years, and have tried a number of audio recoring apps on them.
There are a number of stereo microphones available (from Belkin, Tascam, Blue, etc) that allow high-quality stereo recording on ipods and iphones. There are a number of apps available for recording on Android, but the quality of the recordings is not great. Why is that? Is there something inherent in the Android platform that does not permit hi quality recording?
Sent from my Kindle Fire using Tapatalk

This link might enlighten you a bit. Along with extremely poor audio-latency it would seem that audio recording is also problematic. Strange to find this in an audio device such as a phone eh?

Thanks; I actually used to use the Rehearsal Assistant app. I posed this same question to the developer of J4T, which is a very cool Android multitrack recording app, and I just got his response:
"One reason might be that the best recording quality that is supported by most Android phones is mono, 16-bit pcm, with samplerate 44100. So to make sure a recording app runs on most most android phones, the developer should probably use those numbers and not go any higher.
But it also means it's possible to have android phones that can record at much higher quality, and maybe they are out there. But that capacity may go unused, because the apps are developed for the 'average' phone.
Perhaps on other platforms the 'average phones' have higher bitrates and samplerates.
There are actually 2 ways to do audio recording on Android, but I'm not familiar with the other way (where you can record to AAC or AMR format). Perhaps the quality using those codecs is better than PCM, I don't know.
Please don't take this as a definite answer - this is just a guess from my perspective, maybe a manufacturer (or the Android team) would give a different answer."
I've been using a Belkin Tundtalk stereo microphone with a 3rd-generation ipod nano to make reharsal recordings of my rock band; the quality is actually very good. It records in wav format, stereo, 16-bit pcm, with samplerate 44100. So, outside of the fact that Android records in mono, not stereo, the potential for decent quality is there. The lousy quality must have a lot to do with the cheesy microphones used in the Android phones. If I could find a decent quality mic that would work with my Android phone (or with the Fire), I imagine it would make a big difference.

Yeah, from what I know about Android audio going the other way, the audio-latency issues, Google really managed to screw up on a bunch of levels. The audio app market on the iPhone is pretty big and they just haven't stepped up to the plate for developers from what I can see. I see a few apps coming out like AudioSketch that claim to have custom low-latency audio drivers, but that one isn't available for the Kindle Fire so I really can't say. But, sorry, I am digressing. I'd be curious as to see what results you get from your experiences.

This man doesn't now a thing about sound encoding. PCM is uncompressed audio format so it have smallest use of CPU and it has best quality. Only problem is that is space-hungry in comparison with other codec's.
In audio, whole system is good as the weakest thing in it. You need good MIC, you need good MIC input, you need good audio driver and you need good recording app. If one link in this chain is inadequate resulting sound quality is on level of that poor part.

Hey, just a thought but you might be able to turn your question into a free Kindle Fire if you were so inclined.

Now that you've brought it to my attention, I AM so inclined! That's for letting me know.

I posted my question there, and after about an hour it was Closed as "not constructive" lol.
As I said, I'm not a developer. Even before I posted the question here I googled the subject and haven't been able to come up with a definitive answer as to why this is so. I would think there would be a huge market for after-market microphones for people to use on their Android phones (as there is for iphone and ipod). If I was an iphone fanboy, this would be my first argument against Android - crappy audio recording!

DTS Sound Enhancement - How useful?

The honor 8 Pro has got DTS Sound Enhancement. It is available when you watch a video (and I believe listen to audio). But it seems to only be a simple "on/ off" thingy. Nothing much to customise.
Just wondering how useful is this then, to the consumer?
honor can market and put the DTS branding, but is it really useful?
And you guys did notice this option/ feature, right?

Maybe they should give something OTA an equaliser or surround sound enhancer in future because in the past I tried these effects from the store ,in my older devices , didn't worked accordingly

If only they could improve the sound through the earphone jack, it would be good.

DAC on phone

Hi, first, sorry for my english, it's almost certain that I will mistake some words.
I've read different info about the presence of a internal DAC on the phone, for example poweramp don't see anything for the hi fi option, but on google many people talk about a internal dac for a hi fi quality.
So, is it present or not?

The phone has a 3.5mm jack, so it has to have an internal DAC.

No there is no hifi dac on this phone.

The P2 has a Snapdragon 625 processor, the following is listed on their advanced spec sheet.
Qualcomm Aqstic™
+ Crystal clear VoLTE w/ Ultra HD
Voice (EVS)
+ High fidelity music playback
24bit/192kHz
+ Dolby 5.1 support
Built-in Qualcomm Aqustic central audio processor with Lenovo configured Texas Instrument TAS2555 SMART amplifier, providing the ability to play audio files up to 192 kHz / 24-bit. Sources here, here and here.
Looks pretty good on paper, but the DAC really isn't that good.

widevine. L1

So I've been asking this question on almost all the new phones' forums recently because it's never mentioned in any of the spec websites or the manufacturers website. None of the YouTube tech channels check it either except for one which he also forgets to do for some of the phones.
The question is.... Is this phone Widevine L1 certified?
Anybody who already bought the phone can check through downloading an app via playstore. App name is 'drm info'.
Screenshot would be appreciated for anybody who are looking for this particular feature in the next phone they're gonna buy. Thanks in advance guys.

I'm 99.9% sure if will only have level 3, no other Xiaomi phone has anything different. However, I'd also really like to know for sure as this might decide whether I get this phone or not.

confirmed only L3 as shown in this video review

The china rom has L3 because it doesnt need it, global rom it has L1, just wait

I have the official global ROM (9.6.6.0, phone arrived in an English box with English instructions) - L3 only. Sorry.

Isnt this just a software limitation?
Would it not be possible to just replace som .so and .lib files and manually make L1 work?

As stated by XDA themselves on the Pocophone:
Fixing this problem via an OTA update won’t be possible, most likely. There have been some devices that received updates that bring Widevine L1 certification, but those devices already had the required device-unique secret key in the TrustZone. It’s unclear if this is the case on the Pocophone F1. If Xiaomi chooses to address this issue, they’ll either have to offer a service like OnePlus did or roll out an update that enables L1 support on the software side. Keep in mind that G

Ah so its a chip that runs side-by-side that you cannot access from the main cpu.
Almost like Intel AME with the ME running Minix.
Either a virtual machine running on the soc or a physical chip that communicates back and forth to the soc.
If the kernel image is virtual placed somewhere in the phone there might be a challenge finding this and modify it but keeping the original signature so the phone will boot..and of course it needs to be decrypted.
If its placed on a separate chip its a whole other story. Only way to access and write to that chip is to connect to it with test points or either solder cables to it or desolder the chip reprogram it and solder it back on.
Info: https://source.android.com/security/trusty/
This is for Qualcomm. So its a separate chip inside the soc..seems to have no way to access it from outside

For anyone considering whether to buy or not buy the phone based on this piece of information:
Yes, it only has Widevine Security Level L3, but in my personal opinion, even though it's capable of streaming Netflix or Prime Video content in "only" SD quality, that doesn't look bad at all! I'd consider it to be fully on a par with DVD quality, even in view of the device's display size. It's definitely nothing like a blocky low quality Youtube video or something.
In fact, 'til considering to buy this phone I never realized that something called a "Widevine level" even existed or there were phones not having the "best"/"highest" one; so when I tried to compare with the display quality of my recent Huawei Mate 8, I just then realized that it also(!) "only" got L3 and I nether even noticed the supposedly "low" quality.
So, by all means, if this phone matches all or most of the other criteria you might have and you're no snobby screen density or HD video quality connoisseur, who even spots imaginary pixels on a Full HD display 'cause it's not 4K, 8K, nK... HDR and whatnot, please don't miss out on a perfectly good phone (especially regarding the seeming lack of alternatives in the ranks of real(!) phablets)!

Well... 480p is DVD quality... So you are spot on with that.
The real issue is that we are in the age of 1080p+ and 4k BlueRays.

Yeah, that's right, I just wanted to add this to the discussion, because reading about this issue, I somehow got the impression, that the quality would be much worse than it actually is and I wanted to help others to put this in perspective accordingly.
I guess many of us also still have large collections of DVDs or even still buy new ones and don't consider the quality to be particularly "bad", although - of course - one could always do better. So I don't think they'll consider the streaming quality offered by this device to be particularly bad, either (4K or better isn't an option here anyway, regardless of Widevine level ).
So, to get this straight: Streaming quality on this device in SD quality is much like the difference between a Blu-ray and DVD - not like a DVD vs. an old-timey blocky/blurry YouTube flash video. If you can live with that and see no other downsides, you likely won't regret your purchase, otherwise: rethink! That's all I wanted to say.

I'm not a big HD Nazi so I'll probably not mind much but I do watch 1080p copies if they are available simply because why not. I won't be crying wolf over this, especially because I'm fairly sure a custom ROM will rectify this issue further down the road, but it is something I don't understand given how much media the populace consumes at a regular basis now-a-days. Especially on a device who's main feature is a big screen.

We should talk about this issue. Because nowadays android phone's screen gets bigger and bigger.
My mi max 3 has 6.9 inch screen. And I know Honor 8x max has 7.2 inch screen.
And newer device and flagship goes 6+ inch screen. And there have so many 8.4 inch or 9 inch screen android tablet.
Why people pay for the big screen? People wanted to see TV screen-ish quality, right?
That means video playback should increase it, too. Doesn't it?

To be absolutely honest I bought it for YouTube, manga & comic reading and it's absolutely phenomenal battery.
Netflix and the likes are just the cherry on top... Besides, you can install a patched Netflix APK that skips the widevine checks and feeds you the 1080p streams anyway... Even if your device doesn't have L1.

Oh, thanks for the tips, MrColdbird.

This stuff no longer works and there is no workaround for a higher quality than 540p on L3 phone. Already tried lot of these apps :/ movies get ultrahd content icon, but that's it. It won't go higher than 540p, you can check that on test patterns.

If you can tell the difference between DVD and HD on a 7" screen ~350 ppi then you are not watching whatever you are watching... You are looking for those imperfections... Enjoy the content and don't look deliberately for things you might not see... It's a under $300 device after all...
