2016-08-02Revert "Don't use expressions with side effects in macro parameters"Martin Storsjö
This reverts commit 25bacd0a0c32ae682e6f411b1ac9020aeaabca72. Since 230b1c070, the bytewise AV_W*() macros only expand their argument once, so revert to the more readable version of these. Signed-off-by: Martin Storsjö <martin@martin.st>
2016-07-31Don't use expressions with side effects in macro parametersMartin Storsjö
AV_WB32 can be implemented as a macro that expands its parameters multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the compiler doesn't support GCC attributes); make sure not to read multiple times from the source in this case. Signed-off-by: Martin Storsjö <martin@martin.st>

Header does not contain the number of channels, but rather the encoder version, so rename the variable, and read the additional byte.
