* avutil: reintroduce lls1 as the 52 ABI needs itMichael Niedermayer2013-11-174-1/+240
| | | | | | | | | | | | | | | | | | | | | | lls1 taken from ff130d7 This is incompatible with libavcodec version 55.18.100 to 55.43.100 except 55.39.101 This incompatibility is caused by these libavcodec versions depending on a libavutil 52 which is ABI incompatible with the previous ABI 52 you can avoid this incompatibility by upgrading your libavcodec so it does no longer depend on the invalid ABI See: 502ab21af0ca68f76d6112722c46d2f35c004053 See: cc6714bb16b1f0716ba43701d47273dbe9657b8b See: 41578f70cf8aec8e7565fba1ca7e07f3dc46c3d2 See: Ticket3136 Tested-by: marillat Signed-off-by: Michael Niedermayer <michaelni@gmx.at> (cherry picked from commit b382d09d29be90e0947295a70cdcbaa60b9030b8) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | 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.
