Merge remote-tracking branch 'qatar/master'
* qatar/master: (25 commits) rtpenc: Add support for G726 audio rtpdec: Interpret the different G726 names as bits_per_coded_sample rtpenc: Change rtp_send_samples to handle sample sizes other than even bytes rtpenc: Cast a rescaling parameter to int64_t h264: cap max has_b_frames at MAX_DELAYED_PIC_COUNT - 1. ARM: fix indentation in ff_dsputil_init_neon() ARM: NEON put/avg_pixels8/16 cosmetics ARM: add remaining NEON avg_pixels8/16 functions ARM: clean up NEON put/avg_pixels macros fate: split acodec-pcm into individual tests swscale: #include "libavutil/mathematics.h" pmpdec: don't use deprecated av_set_pts_info. rv34: align temporary block of "dct" coefs Add PlayStation Portable PMP format demuxer proto: Realign struct initializers proto: Use .priv_data_size to allocate the private context mmsh: Properly clean up if the second ffurl_alloc failed rtmp: Clean up properly if the handshake failed md5proto: Remove the get_file_handle function applehttpproto: Use the close function if the open function fails ...
