I read the post on the FireTV and how to fix stuttering but none of those solutions helped me. As a final try I disabled libstagefright only under hardware acceleration and it plays fine now.
(goto System->Settings->Video->Acceleration>disable Libstagefright)

I posted this a while back as the stuttering came as a result of switching to software decoding which by default i believe has libstagefright disabled. But with the default settings of hardware decoding and libstagefright enabled I experienced no stuttering just a somewhat reduced picture quality. Which xbmc are you using or are you using spmc?

When I tried libstagefright on and medicacodec off it stuttered, when I tried libstagefright off and medicacodec on it played fine. This was on both XBMC Gotham and TVMC. Picture quality seemed to stay the same no matter if they were enabled or not, same for software decoding. All gave stutters except for what I posted above.
It could have something to do with what TV one is using... Fire stick is decoding and TV is decoding causing stuttering.

strange, with lib. off i get stuttering, bad. but my contrast is better. that's with hardware enabled.
the stuttering makes it un watchable, but not liking my contrast muted.

More testing, installed spec 13.3.3 I think, the latest. Seems the effects of the two hardware checkbooks are reversed. Results are the same, better contrast, but not smooth. Interesting that the builds are flip flopped with the settings like that. That could add to the confusion for Sure.
Have you tried using SPMC? Every version of Xbmc gave me stuttering on my generic RK3188 tv box except this one. No stuttering at all. I have this installed on all my devices including my AFTV. Might be worth a shot.
I'm a little late to this thread and not really tech savy but I just got a fire stick with kodi and I am having the same issues with the sound skipping. I have tried changing the libstagefright/medicacodec on\off and still can't get it to work. Can you tell me more about the SPMC? How do I get it? What is it?

I've set my Coreplayer up as per the posts elsewhere in the Athena threads and the video quality is almost perfect now.
I'm using 320x240, DivX 6, 500-700KBps constant bitrate files.
Stereo MP3 audio. 96kbps or 128kbps.
After 10 mins of playback the audio slowly starts to lose sync (it plays fine on my PC).
Has anyone got any ideas what I need to do to stop the audio from losing sync?
Any help greatly appreciated.
hi
when you say "outof sync", does this mean that the audio is fine but the video is not "in time"? if yes, that's exactly what i was going to ask in the forum =) but i'll be trying the parameters you set. i've been meaning to ask the "optimized" setting for this application.
cheers

Yep, that's exactly it. It starts off fine, then ever so slowly the video gets ahead of the audio.
I've 'fiddled' with just about every setting I can think of within Coreplayer but have yet to find a solution.

ive already asked this question. with no replys. ive tried every setting and format possible. still loses sync. it doesnt matter if its from the sd card micro drive or streaming. it still loses sync. ive even tryed disabling the auto scaler and running tcpmp over clocked. still loses sync. im a a loss. if you find a solution let me know.
I guess we need to wait for the next version of Coreplayer which will (hopefully) be released on the 18th of June. It supposedly fixes some of the ATI issues.
I am so sick to death of this subject!! Not mad at you guys, but at ATI/AMD. This has been an ongoing issue since September last year when the TyTN was released with the ATI Imageon chip, and due to no input or support from ATI/AMD, Corecodec cannot fix this issue as it's to to with the Imageon hardware.
Bottom line is find the settings that work best for you. For me, I find TCPMP v0.72RC more stable and versatile than CorePlayer v1.04. Also set Video driver as Imageon (NOT Imageon decoder!) this yields best performance and visual quality 'during' playback.
If you're using DVD-Rips use the above setting, but if your playing/stretching QVGA 320x240 on your Athena, then Rawframebuffer mode is even more stable in the GUI, but lacks the ooomph of the Imageon driver, which to some extent might well eradicate your lipsync issues.
One more test folks. Play your video whilst your Athena is pluggen in to mains power. See if the lipsync is still out. If it is make manual adjustments in the A/V offset in TCPMP under Advanced.

How cam that you can use it.
I'v tried 0.72 version as well as 0.81 and both give me the "crash.txt" error while starting TCPMP.
Oh, you are using CorePlayer not TCPMP, right?
im using coreplayer the latest version becuase tmcp as you said keeps on crashing, (for me too).
With a hard reset playing even a video in windows media player still gives a audio lag. Its so bad, now i don't care about quility just let me have a video with audio i don't care how bad the video looks like.
Does anyone have any solution? ive tried all kinds of "video output" settings and it still gives audio lag (even raw framebuffer)
FINALLY! ah found it after lots of searching of google and forums and sites...
its -400ms and its perfect thought the whole video..
(Note: the best method that i use to see if its in sync is to watch a lecture and then watch their mouth real careful and you'll see that -400ms gives the best results )

What is this -400Ms?
-400ms is -400 milliseconds as in time. The minus sign means "start playing the video 400 milliseconds ahead of the audio. Its perfect for core player put all the settings on max just take acceleration and dithering off. And it plays a DVD rip perfectly no conversion very sweet on its 5 inch screen
If you don't know put the -400 in the settings next to "manual A/V offset +/-" and just type in "-0.400"

I am confused, because on the other thread, you mentioned it did not work.
it does for like 5-10 minutes then audio gets our of sync

Coreplayer plays flv files, yes. There's no need to separately install additional component. It benchmarks better than TCPMP in my test.
Hi,
I'm a new nook owner, but I'm not new to Android (I've had a Galaxy S for some time now). I just received my 'new' nook which came with CM7.10 (CWK74) on it and it's working fine except for hardware acceleration for video playback. I've tried a couple of HW accelerated players (Dice & BS Player), but neither of them seem to be able to play anything back using HW mode, only SW. I've tried a number of different files, both HD & SD, no difference.
Interestingly, Dice seems to at least try to play in HW mode, (the HW indicator shows when you initially try to play a file) but then immediately falls back to SW mode.
Anyone got any suggestions as to what might be going on here?
The videos are most likely not encoded properly for the nook... either the frames are too large or they aren't in h.264

So are you saying that in order for hardware decoding to be available, the videos must be encoded in a certain format? My Samsung Galaxy S plays the same videos in Dice with HW decoding without any issues (I know it's different hardware, but the principal's the same; I have not re-encoded the files for my Samsung and they play fine).
it seems from my experience anyway playing larger files or hd type that arent in h.264 lag some

So is your player in HW decode mode?
atm im using an ICS version and not CM7 so I cant tell you for sure and I dont really remember if it was or not. Head hurting so cant think atm sorry.
I've never had much luck with DSP video acceleration of H.264 on the NC with the various video players. But YouTube and Netflix do work mostly fine and they use DSP playback.
The problem is that the drivers and kernel for the Nook Color are a bit of a homebrew collage and there are problems. The devs do the best that they can with what B&N provides and with what can be scraped together from other devices.
Hi. I'm currently running MIUI 2.1.20 (see link below)
http://forums.miui.us/showthread.php?13388-MIUI-us-Kindle-Fire-rom-Updated-2-1-20-0xD34D
One problem for me is that I can play streaming videos from the Net and user-uploaded videos in Facebook, but when they play, the video is all choppy, like how a TV is out of tune with like diagonal lines running through it, so it's pretty much un-viewable. The audio plays fine, and the video plays, just can't really make it out at all. So, this happens when I try to watch videos from web-sites that aren't in YouTube & Netflix (those work fine).
Was wondering if there has been any development regarding a fix for this issue in this build of MIUI?
If not, does anyone know if the 2.2.3 ICS build of MIUI addresses this issue? (see link below) It's not listed as a known issue, but I don't want to assume it's fixed before flashing to it.

I use MX video player for all my videos. You can set it to SW decode and its pretty good about playing all videos without lag.

Right now, the lack of hardware acceleration in the multiple ports of ICS for the Fire prevents HD video playback, and often leaves SD video pretty laggy or choppy. Also, with no native support for Adobe Flash when streaming video, that can degrade the quality as well, if not playing whatsoever. The devs are working to get this resolved, but as it's a really complicated process, it still may be awhile before it's resolved.
Hello
I have just received my Nexus and one of the first things I tested on it was the video playback on the AMOLED Screen. One Strange thing I noticed is that while playing any video in MX player (or any player for that matter), if the decoder is the default HW decoder, there is a backlight bleed like in LCD screens and the video doesn't run on an all black background which is really annoying. If I switch the decoder to SW, then its all black like it should be on AMOLED screens.
Though this is not a huge annoyance, but I'm just wondering why is it so ? Has anyone else experienced the same. I'm attaching two screenshots which show the difference.
This is interesting, looking forward to answers

Yea its been posted many times already, basically the hardware decoding on video is set to 16-235 on the rgb instead of 0-255, so using the hw encoder it doesn't get to true black.
Custom kernels have already fixed it, it's been posted on the bug tracker for Google too
Sent from my Nexus 6P using Tapatalk
If you bring first screenshot into Photoshop and sample colors HW decoder follows digital video standard which has RGB values crammed 16-235. It is set this way so older external displays don't choke on the signal.
It's a bug that Google know about, the custom kernels fix it just now but Google will fix it in later Roms.
Google is in the Rainforest working on eliminating the bugs...
Nexus owners are beta testers remember?
Thanks for your replies guys, found a thread on Google Product Fourms. This seems to be a known problem with the new security updates. I had updated my device as well as soon as I had received it, hope Google fixes it soon. For now, SW decoder is the way to go for local media files, though it struggles to play 4K video with SW decoder.

Funny how a security update can glitch something like this. I guess they're pushing more changes than just security in these updates.
The same software issue on 5x BTW, hoping it gets fixed soon.
Videos in some apps look horrible if not the native resolution. Mixer or Twitch shows the problem very clearly. 160p show each individual pixel very sharply. 1080p is the only resolution that looks clear.
issuetracker [.] google [.] com/issues/124593215 This seems to be the same issue. Something to do with the Skia Renderer using nearest neighbor scaling instead of bilinear/bicubic.
github [.] com/google/ExoPlayer/issues/6244 According to this link, apps using TextureView in ExoPlayer do this on 9.0 and newer on some devices.
Using adb shell setprop debug.hwui.renderer opengl doesn't seem to do anything.
Does anyone else have this problem or a solution?

That's the problem on online video because the Wi-Fi is slower.
You can try Kodi or YouTube to test the resolution.

It has nothing to do with the internet speed, it is the way the video/image is scaled to the screen. The second link has a side by side comparison, but certain apps are using nearest neighbor scaling which makes videos look like there is no anti-aliasing, although its even worse than that.
You can compare identical streams in identical resolution with the xtra twitch app(proper scaling) and the official twitch app(bad scaling).
