Video Recording -- DO NOT PRESS "BACK" instead of "STOP"

So yesterday I was recording my friend's graduation, and I was using my Epic. I never had a problem with recording before, and I had taken several videos earlier in the day. Finally after she walks across the stage and sits back down, I'm ready to stop recording. But somebody said something to me and I got distracted and instead of pressing the Stop or Pause buttons on the screen, I pressed the Back button below the screen. Oh well, no problem, I thought. Surely it would still save the video. NOPE!
The video was not in the gallery and I could not find a temporary file anywhere with the right size and timestamp using the file manager. The temporary cached file had to be on the SD card somewhere, because there was not enough RAM or internal flash memory in the phone to store the recording. So I pulled the battery to prevent any further writes to the SD card so I could do some more forensics when I got home.
At home, I found the deleted file on the SD card using TestDisk. It was named temp_video and was in the folder /DCIM/Camera. The timestamp was right, and the file size was 48mb. Sure enough, the headers showed it was a 3gpp encoded video in an mp4 container, just like the rest of the videos recorded on the phone. But no player would play it and no video fixer program would fix it. Apparently the phone has to write a very critical header to END of the file (guess that makes it a footer) when it finishes recording. The MP4 container is extremely sensitive to any missing data and the entire video is basically unrecoverable if the footer data is not written. I did try hacking up the file with a hex editor and copying headers from a good file. I learned all about MP4 file structure but I could still never get anything useful out of it.
So I learned a couple of lessons from this little incident. In conclusion:
Don't EVER EVER EVER press Back instead of Stop when recording a video. The software will helpfully delete the video you have been recording.
Mp4 files are trash. Why do they have to be so ridiculously sensitive to missing data? (put the critical headers at the BEGINNING of the file, for %^&'s sake!!) Why can't the phone record in any other format? I might run out of battery suddenly, or an app might crash, and the same thing would happen.
I believe the app that does the actual recording on the Epic is called CoolIris. I'm not sure if this app is specific to Samsung phones, or if all Android phones use it. I will be looking for alternatives now that can record .mpg or .avi or anything else.

Thanks for the very informative post. Only recently did I have a generic recording failure issue from different conditions, but this will be a good one to remember also. Really the camera app should have some kind of failsafe dialogue box to help prevent this issue at the very least.

Thanks for the heads up I don't use the recording feature regularly, but definitely will avoid this. Sorry your couldn't recover your friend's graduation :*(

I did do some recordings in 1280x720 yesterday. The first couple of videos worked OK, but when I tried to do a longer recording it would go about 10 seconds and then a message would pop up saying "The recording failed". Maybe the write speed to the SD card is too slow and can't keep up?

It's OK, my wife was sitting beside me recording with her EVO 3D. Unfortunately it was blurry because the lens cover on her otterbox was smudged, and she was not holding it very steadily. I know I had a great video and I was mad at myself the rest of the day b/c I lost it. I guess we will end up paying the professional photographer for the "official" stuff anyway..

I'm trying to figure out if thats a rom issue or if it happens on stock as well.

I use to have the recording failed message all the damn time on stock ec05, since moving to srf 1.2 no issues recording. I'm running clean kernel at stock speed /voltage.

Stock eg22. It has happened from time to time since the eclair days. Tried reformatting sd card. I think the one that comes with the phone just sucks.

Problem with google search and playing videos
Hi! I want to report bug with google search app (GoogleQuickSearchBox.apk) on enabled tablet ui. I'm on m5 v2 build with latest camera + youtube fix with LCD Density set up to 128. When i press it, it fc. It doesn't work at all. And second bug, when i record video witch Camrecorder, i can't play it from gallery. First time when i press play button it shows error, i press ok, and when i press second time play, it runs, but only sound - video is full of artifacts. By the way, this rom is exelent! It runs perfectly! And I'm sorry for my bad english.

it is a known issue with the video as we dont have full hardware decoding so the workaround is mx player arm v7 codecs and set the encoding to software as for the search bar first time i hear about it i will try it out now

Hi this thread is a great Idea. I actually have a couple of questions
if I use youtube and camera fix from the third post, Youtube app will work properly and panorama mode in camera will work but I won't be able to record videos more than 30 secs right?
also what resolution does the video camera record in? and can I change it?
thanx in advance

Thanx I applied it and testing it right now
there's no way yet the camera can record in HD right?

Its a hardware limitation the highest we can record is 800x480 and the devs are working on it

Huge Issue:
Sometimes (after a while of usage) my apps are not starting when i press their icons. The app drawer isnt working aswell then. The Icon just glows up, but nothing happens. I cant get into settings aswell. After this happens, my screen gets a SOD if i turn it off and want to wake up my device. Only solution for that: Pull out the battery or if there is no SOD yet, reboot the device.
This problem does NOT belong to the launcher, since i have tested apex, nova and trebuchet.
This problem does NOT belong to a specific a2sd script, since i have tested Link2sd and darktremor script.
This problem does NOT belong to a bad flash or sth like that, since i have made 3 installs from scratch for now (task29) and always had the same issue after a while.
My config:
Bootloader: Tested with clk and magldr
CWM: latest
ROM: [04-05-12][ROM] Unofficial AOKP for HD2 [Milestone 5 v2][HWA][4.0.4][tytung_HWA_r1]
Kernel: tytung_hwa_r1
This issue seems to be more rare since i have only heard of a few others having these issues.
Regards

The video recording crashes then it will show blank white when the recording reaches EXACTLY at 10 minutes making the whole recording corrupted.
Is there any fix in this issue? Or recommend other ROM...

Well, you can tweak media profiles, but with lgCamera you can change various settings right in the app. I remember having white screen and error, while I was on PrimeHD 6.0 and using h.264 encoder. But the white screen was there right from the begining of recording. So it is not a general cm7 bug, with h.263 there wasn't an error, there is maybe some problem with your phone. Try lgCamera with h.263 and see what happens.
If there is still the error, try fullwipe. BTW, what kernel are you on?
Oh, and what about sd card? 10 minutes is quite a lot, maybe it is running out of capacity?

The SD card is pretty slow, in my opinion, but it is strange, that the error appears after 10 minutes...dunno. I recorded a longer video, cca 12 minutes, there were few glitches and sync problems, but no white screen. I have class 6 card.
Try to revert to stock rom, stock kernel...I can't figure out, how to help you anymore, sorry

i suggest PetrukDroid v3....install rom then flash Gapps-PetrukDroid set up your account and then flash another gapps cuz with PetrukDroid gapps video recording will be LAGGY...

Video Recording Issues

I've noticed an issue lately and I'm not sure what is causing it....
But when I go to start recording video, I press the Record button and it doesn't record right away... it takes anywhere from 3-5 seconds before the 00:00 timer starts moving up and actually recording. Does anyone know what could be causing this delay in recording? I have tons of free space on the memory card(that it's set to record to) and can't think of anything that would be causing this. Thoughts?

Open camera and go into settings and make sure timer is off. If it is off all you can really do is go into settings/apps and clear all the camera settings to default and reboot.

Yeah timer is off. It's not similar to a timer issue as much as it is like an "accessing hard drive, please wait" sort of issue. The screen lags before starting and when it finally unlags, it starts recording. I've rebooted numerous times, no help.

I believe all those settings came with MM camera software lol. Aside from clearing the apps settings and data I'm not really sure what the deal is, factory reset would probably take care of it but nobody really wants to do that unless they really have to.

You might try unmounting the SD card, then remounting it. If it started after the nougat update it could be a squirly setting...
Maybe reformat it also?

Google Camera problems.

Hi everyone,
I hope this is the right section for this kind of questions.
Anyway, I'd like to know if someone can help me.
I'm absolutely not able of getting Google Camera to work.
I tried different version, I think the problem is caused by the fact that our phone has a SD801...
But I have no idea how to solve it.
Camera just crash as soon as I open it.
Thanks to everyone!
Lorenzo Benevento.

Not just coz soc is sd801
It is arm based
Google camera is nowadays built for arm64 architecture

And which version would work?
If there is one obviously!

I tried but I can't downgrade. How come? It shows "corrupted package".

I downgraded to 2.7.010, It works and connect to camera but I'm unable of taking videos!
It start recording but when I tap on the stop icon it freezes and the only thing that I can do is to reboot the phone. Or close the app (but camera would be busy, so no tourch for example or no other photos until the next reboot).
