  avcodec/osq: avoid undefined negation
  
  Fixes: negation of -2147483648 cannot be represented in type 'int32_t' (aka 'int'); cast to an unsigned type to negate this value to itself

  avcodec/hw_base_encode: log the readable error message on failure
  
  Currently, if there is a hardware encode failure, the numeric
  error code will be printed making it somewhat hard to get to
  the root cause of the issue. Print the readable message generated
  by av_err2str() instead.
