I'm having problems with sound during video playback in Coreplayer. It loses the sound, pausing and unpausing video helps sometimes. as far as I know most Trinity users have problems with video in Coreplayer due to unfixed bug related to ATI Imageon, but interesting point is that I have no problems with video, only with sound. What it might be? Flashed with latest russian ROM.
found the thread where the same problem was discussed http://forum.xda-developers.com/showthread.php?t=318532
interesting, why does Coreplayer react to touchscreen action this way?
One picture is worth a thousand words
Recorded with Tapemachine. Same conditions, same audio source, same settings... The only difference is hardware autogain control enabled on first sample, and disabled on the second one
How to disable it during video recording? No idea yet
that's a good improvement,maybe supercurio knows how to do it.that would be awesome for a good video recordings.
At least we now know the problem. Very good work.
Hmm i am really waithing for this fix. recording is HD is quite cool and good quality but its useless because the sound always go's bad because its recorded to loud.
New info:
AudioHardwareInterface: AudioHardwareBase::setParamenters(downgain=0)
That's how Tapemachine switch off hardware auto-gain
And auto-gain off seems only to work with mic set to front (AudioSource: VOICE_RECOGNITION)
Thanks to aLogcat app

hohoho. Now we just need someone with the knowledge to do that. Thanks rafalense for find out this
Don't forget that it needs those settings to be optimised for audio calls. Most likely, with theses settings, while in call, the audio will catch more of the surrounding than the vocal itself.`
So the best way for this to works would be to make an apps that does the command then goes dormant. Then you can record whatever and, when done, disable and close the dormant app (kinda like TrackerBooster)
BTW, don't forget that you're recording with a crappy built in microphone from a smartphone. I'll try to do the same with an external microphone to see.
I own both the Galaxy S and the Samsung Wave s8500.... And, i gotta say, that the Wave has MUCH better sound when recording video at 720p + Its much better synced with the actual video... Maybe you could look at the Wave and how i manages sound? It has the Bada OS (unfortunately)
Hi !
That's something I'll fix soon using hardware auto-gain.
For now I'm working on a jitter issue and the gain is the next one in the TODO list
As the jitter one is quite difficult I cannot give ETA yet

Thanks a lot, supercurio, without you, our galaxy wouldn't be as good as it is.
any updates on this item yet? this would make recording video's so much better.
Try this kernel, mic gain issue seems to be solved, plus other sound improvements:

Also, follow Supercurio. Headphone & FM Radio improvements already done, currently busy with mic:

I'm busy moddifying stock camera, in order to increase samplerate and bitrate. Updates to come
Great efforts by the members of xda, REALLY.
The idiots at Sam**** should have sorted this out though.

video bitrate is already quite high but higher audio bitrate might be a good improvement
Hardware is able to record @48000 and around 256Kbps, but video and audio are out-of-sync
My guess, something coded wrong in the driver, so lets see if voodoo sound new kernel fixes it, and then we will record hd video with hd audio as well
A did a test for you minutes ago, check audio info:

why do you think this fixes it.. from my readings that kernel does not muck with video recording rates or microphone gain...
Hardcores K12L?
Check yourself. I did, and mic distortion is reduced considerably

I would recommend trying 44100Hz.

Also possible:
16000 - 22050 - 24000 - 32000 - 44100 - 48000 tested
How can you get the camera app to record at 44.1KHz?
Edit: Got it. Weird though, even though it's 44.1KHz, the cutoff frequency is 12.0KHz instead of 22.050KHz. Not much improvement over 8KHz cutoff, but better than nothing.
I have my Verizon S5 currently sitting on 4.4.4 NK7. I've noticed no matter what video recording app I use, whether it be Snapchat or the native camera app, that audio on video playback always seems a bit distorted if the video was captured in a loud environment. Yet I see friends with other newer android phones and iPhones that have recorded footage the same venues (concerts) where their audio is much more tolerable. Has anyone else experienced this? I've been holding off on updating to lollipop, but if that is a known fix I might go that route.
For example, even recording a video on my car with the audio at a normal volume results in distorted audio quality.
Lollipop won't change anything, cause that's a big problem to not fix immediately. Are you possibly covering a mic when recording? Are phone calls clear? I'm not sure how to fix your problem, I'm just throwing out ideas. A search didn't bring up anything.
Apparently it's a common problem within the Samsung phones:

Was hoping there was a software option to adjust the gain level it records at.

I saw the xda thread but wasn't sure if it was the same. Someone said disable the noise reduction option, and that should fix it.
I'm not sure if the system update or one of the recent camera updates is the culprit here, but quite a few (but far from all) of the videos taken with Motorola's stock camera end up out of sync. There is a quite significant (up to a second) delay between audio and video, both when playing it back on the device itself as well as when playing it anywhere else.
So not the playback, but the creation of these 1080p videos is somehow bugged. There also is little rhyme or reason why these specific videos are out of sync although it appears to possibly happen more with low light video recordings.

I've noticed this too. For me, this happens mostly when the battery is low. I have heard that big cores get shut off below a certain percentage, so perhaps this has something to do with it.
I've personally noticed the quality of the video capture is choppy. The 1080p 30 fps capture lags when moving objects are on the screen. For example, I shot a video of some quick hand movements (no jokes about male body parts here, please!) and the camera did not replicate them in real time. I would estimate a 200-400 MS delay in rendering.
Anyone have any thoughts?
I started experiencing that large video playing on YouTube lags the sound, especially when a video is long. The sounds go way ahead from the video. It looks like the phone lacks the ram or performance but it has a decent tech specification, should be an issue, especially when I play a video on a low resolution. Has anyone else experienced the same issue?
I have a similar issue with video playback. However, it is not only with youtube, it is with all videos. Even those on google photos, etc. The playback timer doesn't start, but the video starts with no sound, then the playback timer starts with the sound and the video freezes until the sound catches up with the video. The issue disappears with a restart and only started happening recently. Very odd.
Made an account for this lul... Anyways it seems like I fixed the issue on my phone, I disabled the mobile manager, let me know if that works for you. Good luck
I had to update youtube
