Android - What is mediarecorder's maximum maxfilesize?

Question

Android - What is the maximum file size that setMaxFileSize can be set to in respect to Androids mediarecorder? I know it's somewhere between 4147483650 and 5147483650. Why is there a limit in the first place?

I'm recording on to a SDCARD, detecting the size of the cards space before we run.

"ERROR/AuthorDriver(31): setParameter(max-filesize = 7270309850) failed with result -5" "ERROR/AuthorDriver(31): Ln 903 handleSetParameters("max-filesize=7270309850") error" "ERROR/AndroidRuntime(409): java.lang.RuntimeException: setMaxFileSize failed."

Answer 1

OK, I know know that the maximum, after trial and error with a little reasoning is:- 4294967295 (4 Gb).

Does anyone know a way around this limit?

Answer 2

Why is there a limit in the first place?

SD cards use the msdos (FAT16) filesystem, which has a file size limit. This is not an Android limitation, but a limitation of SD cards in general.

Answer 3

I'm working on an android recorder as well.

use StatFs and pass the path of the external storage directory to the constructor and you can call functions such as getAvailableBlocks() and getBlockSize() on the StatFs object.

So that way you know how much more space is available on the SD card.
