I am porting Stagefright to Linux Desktop
So far get to the point when files is opened, sniffed, extractor and codec
are created.
However got stuck at point where Decoding should happen, it seems it is not
executing and stream is not there:
04-20 09:29:34.658 20080 20080 E MediaCodec: getBufferAndFormat - not
executing
04-20 09:29:34.658 20080 20080 W SimpleDecodingSource: [] could not get
input buffer #0
Any ideas what I miss.
On Emulator is should work, since it has all the services, so I am
wondering what I messed up, by modify the code or need to add.
Maybe somebody can hint me?
On Emulator:
130|generic_x86_64:/data/local/tmp # ./stagefright
sample-mp4-file.mp4
thumbnailTime: 52066666 us (52.07 secs)
AVC video profile 77 and level 13
$
avg. 0.00 fps
avg. time to decode one buffer -nan usecs
decoded a total of 0 frame(s).
