avdec_h264 Error Messages

[Brian Panneton]

These keep coming up as well and I can't seem to catch the errors within
code.

0:00:12.830815243  4277      0x35e9cf0 ERROR                  libav :0::
get_buffer() failed (-1 2 (nil))
0:00:12.830839083  4277      0x35e9cf0 ERROR                  libav :0::
decode_slice_header error
0:00:12.830853090  4277      0x35e9cf0 ERROR                  libav :0::
mmco: unref short failure

I noticed that when these errors come up my processing seems to hang. If
these are not critical errors that it might be due to something else within
my pipeline.

Thanks,
Brian
