* | lavu/opt: add AV_OPT_TYPE_CHANNEL_LAYOUT and handler functionsStefano Sabatini2013-10-173-3/+78
| | | | | | | | | | The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify channel layouts using the format accepted by av_get_channel_layout().
* | lavu/channel_layout: change av_get_channel_layout() behavior at the next bumpStefano Sabatini2013-10-174-3/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new syntax is preferred since it allows backward syntax compatibility with libswr when switching to the new option handling code with AV_OPT_TYPE_CHANNEL_LAYOUT. With the new parser the string: 1234 is interpreted as a channel layout mask, rather than as a number of channels, and thus it's compatible with the current way to set a channel layout as an integer (e.g. for the icl and ocl options) making use of integer option values. ff_get_channel_layout() with compat=0 will be used in the AV_OPT_TYPE_CHANNEL handler code. The user is encouraged to switch to the new forward compatible syntax, which requires to put a trailing "c" when specifying a layout as a number of channels.

| * x86inc: remove misaligned cpu flagHenrik Gramner2013-10-071-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

| * x86inc: activate REP_RET automaticallyLoren Merritt2013-10-071-5/+31
| | | | | | | | | | | | | | | | | | | | | | | | Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition. REP_RET is still needed manually when it's a branch target, but that's much rarer. The implementation involves lots of spurious labels, but that's OK because we strip them.
