* qatar/master: (25 commits) Replace custom DEBUG preprocessor trickery by the standard one. vorbis: Remove non-compiling debug statement. vorbis: Remove pointless DEBUG #ifdef around debug output macros. cook: Remove non-compiling debug output. Remove pointless #ifdefs around function declarations in a header. Replace #ifdef + av_log() combinations by av_dlog(). Replace custom debug output functions by av_dlog(). cook: Remove unused debug functions. Remove stray extra arguments from av_dlog() invocations. targa: fix big-endian build v4l2: remove one forgotten use of AVFormatParameters.pix_fmt. vfwcap: add a framerate private option. v4l2: add a framerate private option. libdc1394: add a framerate private option. fbdev: add a framerate private option. bktr: add a framerate private option. oma: check avio_read() return value nutdec: remove unused variable Remove unused variables swscale: allocate larger buffer to handle altivec overreads. ...
