Comment (by quinkblack):

 The device is an emulator. I think there is no real hardware
 decoder/encoder on the emulator, only software implementation. FFmpeg
 mediacodec wrapper via JNI skip software decoders explicitly, so decoder
 doesn't work.

 You can try the NDK implementation, put an '-ndk_codec 1' before -i

 {{{
 -ndk_codec 1 -c:v h264_mediacodec -i
 }}}

 I guess it will work. It's only for test. There's no sense to use
 MediaCodec software decoder, since FFmpeg's software decoder do better,
 that's


 {{{
 ffmpeg -i test.mp4 -c:v h264_mediacodec out.mp4
 }}}


 Should work. There is no real mediacodec hardware encoder neither. The
 software implementition has YUV420P support, so -pix_fmt nv12 is
 unnecessary.
