Merge commit '1470ce21cec5ee26e106e2a884c26bbf84e5aaea'
* commit '1470ce21cec5ee26e106e2a884c26bbf84e5aaea':
Bump libavcodec and libavformat minor versions for G.723.1 decoder and demuxer
G.723.1 demuxer and decoder
Add a shift parameter to celp_lp_synthesis_filter()
libopenjpeg: K&R formatting cosmetics
yadif: use emms_c() instead of inline assembly for emms invocations.
ac3: don't use different names for option tables in the template file.
lavfi: use const for AVFilterPad declarations in all filters.
adpcm: don't duplicate identical AVSampleFmt array for each encoder.
configure: cosmetics: Group test dependencies together
configure: add more passthrough flags in tms470 filter
configure: move flag filtering functions out of if/else blocks
Conflicts:
