The table below describes the media format support built into the Android platform. Note that any given mobile device may provide support for additional formats or file types not listed in the table.
Note: Media codecs that are not guaranteed to be available on all Android platform versions are accordingly noted in parentheses—for example "(Android 3.0+)".
Table 1. Core media format and codec support.

| FLAC | • (Android 3.1+) | Mono/Stereo (no multichannel). Sample rates up to 48 kHz (but up to 44.1 kHz is recommended on devices with 44.1 kHz output, as the 48 to 44.1 kHz downsampler does not include a low-pass filter). 16-bit recommended; no dither applied for 24-bit. | FLAC (.flac) only | ||

Ugyanakkor a MediaRecorder.VideoEncoder dokumentaciojaban azt irjak, hogy API Level 3 ota tudja. Ezt is idemasolom:
A tapasztalatom pedig az volt, hogy 2.2.1-es Firmware-nel ha ezt allitottam be akkor siman mukodott (valoszinuleg fallback-elt h.263-ra), de 2.3.3-as Firmwaren probalva IOException-t dobott a MediaRecorder.prepare(). A 2.2.1-es egy Samsung Galaxy S GT-I9003-ason volt, a 2.3.3-as pedig egy GT-I9000-esen.
