STR. on emulator-jb, git gecko ver:85b8bb0ff931e 1. get media stream from fake getUserMedia 2. record the media stream 3. got onerror callback log: I/OMXClient( 535): Using client-side OMX mux.

SoftAVCEncoder does not support encoding video resolution > CIF (352x288) (See http://androidxref.com/4.3_r2.1/xref/frameworks/av/media/libstagefright/codecs/avc/enc/SoftAVCEncoder.cpp#60). Need to use different AVC/H.264 encoder configuration if running on emulator.

Incorrectly set QA Contact field in previous editing.

Use Android system properties API to check if we're running on emulator and adjust parameters accordingly.

Return error rather than assert/crash when input size too large. (Thanks to feedback from :CJKu and :rlin)

Another suggestion is instead of return NS_ERROR_INVALID_ARG here, you may if (aWidth > 352 || aHeight > 288) { mMayFailedBecauseOfResolutionToBig = true; } After getting an unknown error callback from MediaCodec, in error callback function, write this log: CODEC_ERROR("SoftAVCEncoder doesn't support resolution larger than CIF");

Update commit message & carry r+ from roc.
