Code for generic Appro_avi_save.c... may be able to see how disk space is checked?
statfs64 is called in the Itronics version which per linux doc returns the number of free blocks. Doing a "df" on the card shows that it's using 1k blocks... so we're looking for about 51,200 blocks (50 MB / 1024k). Anyway, I think the solution is here...

Actually... I think the key is in the orange numbers in the bottom left hand corner of the pic.
So, if we assume that R3 holds the "free blocks (space)" then all we would need to do is change #0xFC00 to a larger number.
Currently, 64,512 blocks is equal to about 66 MB. Hence the higher bitrate mod file producing 70+ MB files is causing the program to run out of space.
Will try to increase the number tonight and see what happens.
Code:
CMP R3, #0xFC00 ; R3 - #0xFC00 (= dec 64512)
BCS loc_D244 ; goto loc_D244 if R3 >= #0xFC00So, if we assume that R3 holds the "free blocks (space)" then all we would need to do is change #0xFC00 to a larger number.

So after over a week of no problems, I got the SD error again today. The last time it happened, I just power cycled the camera and I was good for the rest of the drive. This time, however, the error persisted. It would start up, begin recording, and then start beeping about a minute in. Also, the SD card presents itself to the computer as having 0 bytes free; when it's been "full" other times this week it always still showed 40-60MB free.
Anyhoo, I've deleted about five minutes worth of video off of it and I'll see how it does on the drive home tonight

It was bound to happen unfortunately... I'm still taking a peek at the code, etc. Working in assembly is a pain.
The BlackVue is so much easier to hack!

All right. I give up... there's no easy way to fix this... I scoured the disassembled code and there's no simple disk space check routine... sorry guys.

The only thing I think I can do is do a regular and 12 Mbps video comparison and try and shame ITB to release new code...

I still feel like there's something else going on to cause the error though. I forgot to mention that when I got the error again the other day, it was with my new 32GB card. After freeing up 5 minutes worth of space it's been fine, even after recording another 3 hours of video onto the card. It kind of seems like it has trouble freeing up space the first time, but it's okay after that. Makes zero sense to me.
Is it not randomised based on the fact that if it finishes a 1 minute segment and finds it has less than 30meg free, it WILL still remove old clips? It's only when it has between 30meg and 80meg (roughly) and 'forgets' to free data that there is a problem?
