Merge commit 'cbcd497f384f0f8ef3f76f85b29b644b900d6b9f'
* commit 'cbcd497f384f0f8ef3f76f85b29b644b900d6b9f':
adxdec: use planar sample format
adpcmdec: use planar sample format for adpcm_thp
adpcmdec: use planar sample format for adpcm_ea_xas
adpcmdec: use planar sample format for adpcm_ea_r1/r2/r3
adpcmdec: use planar sample format for adpcm_xa
adpcmdec: use planar sample format for adpcm_ima_ws for vqa version 3
adpcmdec: use planar sample format for adpcm_4xm
adpcmdec: use planar sample format for adpcm_ima_wav
adpcmdec: use planar sample format for adpcm_ima_qt
pcmdec: use planar sample format for pcm_lxf
mace: use planar sample format
atrac1: use planar sample format
build: non-x86: Only compile mpegvideo optimizations when necessary
rtpdec_mpeg4: au_headers is a single array, simple av_free is enough
avcodec: free extended_data instead address of it
fate: Add tests of the ff_make_absolute_url function
url: Handle relative urls starting with two slashes
url: Handle relative urls being just a new query string
url: Don't treat slashes in query parameters as directory separators
