[Q] video playback issues with latest OTA - EVO 4G Q&A, Help & Troubleshooting

Got 2.2 from the latest OTA and have been encountering some video issues. Just wondering if anyone else has them, and if there are fixes.
The major issue I have is videos lag and stutter. With 2.1, 720p videos recorded from the rear camera worked flawlessly. Now, those videos have short stuttering pauses every second. It makes it very hard to watch. 480p videos do not exhibit this problem.
Is it because the data is not being streamed off the SD card quick enough? Some evidence to that is that the thumbnails in the Gallery take noticeably longer to show up.
In 2.1, when I long press on a video in Gallery and select Details, it would show resolution and framerate. This info is not present in the current Gallery. Is there a fix for that?
I'm particularly interested in framerate, because in 2.1, I noticed that videos would be recorded at low fps when the lighting was dark. (some vids I have even dropped to 10 fps!) Perhaps HTC couldn't fix the low fps recording problem and instead just swept it under the run by not displaying the framerate info at all.
Videos played through Rockplayer worked fine in 2.1. Now, the audio is just loud static. Is this related to the codec change in 2.2?
When I come across a .3gp video file with Astro, clicking on it will come up with a "3gp file type missing" message. A workaround of longpress-> open will open it, though.

KS20 Video Recording/Saving Problem

Alright. When I use my KS20's camera for video recording, it seems to work relatively alright, storing on internal storage and using 3gp format @ "super fine" quality. The recording looks fine as I watch it actually record (the camera screen seems to be fluid as I pan around/following what I'm recording). BUT HOWEVER. When I go to -watch- the recorded video on my phone itself (tcmp and wmp) OR on my XP home PC, the video is choppy. The video automatically saves to internal memory...but gets a huge problem when I try and play it (records smooth, and plays back really horribly).
Every 4-7 seconds there is missed/stuttering frames which makes the video very irritating to watch.
This just generally loses the quality of the video due to the slow playback due to these frame issues.
If ANYONE can assist me with this, I would be eternally grateful. I've been trying to figure this out for a long time, and I hope someone can help me.
I will be watching this thread for any answers, and will reply with any further information.
Thank you!

cant play any video on stock gallery, help!

actually i hv suffered from this problem for a long time
it says "sorry, this video cannot be played" in any sense rom if i play any video on it. even those recorded by using camcorder. but i can play them by clicking the thumbnail on the camcorder (on the bottom left of the camcorder after recording)
but still, i can view videos by using other apps
pls help thx
More people got this issue. I had it once, and I think I know the solution.
I had a lot of videos on my HOX. Some of them could'nt be played since I don't have the right codecs/decoders on HOX(example mkv files). Weird thing was they show up in gallery, but every video I played stoped after max 10 seconds of playing (even those that were working before).
After that I deleted the video's which can't play due missing the right codecs. After deleting them I tried again, and suddenly all movies work again.
Don't know if this is the right solution, but it worked for me. And an other work-around is to use a other media player. MX Player does a solid good job.

Juddery ? I'm assuming you mean jittery or stuttering.

i had some lag with 720P and had to reboot the phone it worked good fore a few mins then did it again. i havent tried 1080p but i assume it would do the same since its even more higher def.
ZERO stuttering or pausing on the current CyanogenMod 10.1 build. Just tested it with YouTube.
Can not comment on stock software as I never tried it.

[Q] Video recording at around 15fps instead of 30 on any Non-Touchwiz roms.

This has happened with every Non-Touchwiz based roms I have flashed.
Currently using this rom: http://forum.xda-developers.com/showthread.php?t=1989907
Is there any fix for this? I'm heading away on a trip in a few weeks and I'd rather not have flash Touchwiz just to record video at 30. I've always been a fan of stock android but this is the one bug I cannot stand. I've searched on here for weeks but never found my exact problem, hence this thread.
This happens in every camera app I can find, the image preview in both photo and video mode appears to stutter and lag. Obviously in the photo mode it doesn't matter, but the video maintains this lag and low fps into the video recording. It may even appear to be lower than 15, but I haven't measured this. The front camera appears to be unaffected however.
Regardless of the video/audio codec and resolution combination I use the problem still persists.
There's also a bug where instead of stereo audio, there is only audio in the right side. But that doesn't bother me as long as there is a fix for the fps issue.
Thanks.

Streaming video issue

Hello. So when watching live streams through an app called Twitch, I encounter massive screen tearing. If I set the video quality to any quality other than auto, I get what looks like a vertical sync bug, where the video doesn't line up with itself properly. I attached a screenshot for clarity. Even when I keep the video quality set to auto, the video will freak out and glitch every 30 seconds or so. I can always hear the audio smoothly, and the frames are still being updated within the fragmented video pieces I receive. Note that streaming video on any other app (Opera, YouTube) works perfectly fine, regardless of what resolution I set the videos to. I am running the final Beanstalk KitKat 4.4.4 release, and haven't had problems with Twitch videos on Lollipop, but Lollipop's instability encouraged me to roll back to KK. I've tried forcing GPU acceleration and disabling HW overlays to no avail. Any help would be greatly appreciated! Thanks!
