 Replying to [comment:3 quinkblack]:

 -ndk_codec 1 -pix_fmt nv12` works, which means decoding to buffer and feed
 it to encoder, rather than decoding to surface.

 1.I tried with `-pxfmt nv12`, and got the same gibberish result
 2.Got the error `Error while opening decoder for input stream` when trying
 to decoding to buffer

 I have attached the console log for both of them
 (`console_output_nv12.log` and `console_output_decoding_to_buffer.log`)
