examples/Makefile: disable -O2 optimizations There is no much point in optimizing example code, and the -O2 flag is annoying when debugging. 2013-06-26 14:13:58 +00:00			`CFLAGS += -Wall -g`
examples/Makefile: give priority to pkg-config flags In case CFLAGS/LDLIBS are already defined and conflicting with the pkg-config flags, give priority to the latter since they are used to detect compilation flags. This should fix for example the case where there are many different instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say -I/bar/include. 2012-08-24 14:49:04 +00:00			`CFLAGS := $(shell pkg-config --cflags $(FFMPEG_LIBS)) $(CFLAGS)`

examples: rename avcodec.c to decoding_encoding.c Restore the old name, which was more meaningful and consistent with the names of the other examples. 2014-04-01 09:12:51 +00:00			`decoding_encoding \`
doc/examples: rename demuxing to demuxing_decoding. That example shows how the decoding process works, not only the demuxing. 2013-11-04 11:35:17 +00:00			`demuxing_decoding \`
avcodec: export motion vectors in frame side data on demand The reasoning behind this addition is that various third party applications are interested in getting some motion information out of a video "for free" when it is available. It was considered to export other information as well (such as the intra information about the block, or the quantization) but the structure might have ended up into a half full-generic, half full of codec specific cruft. If more information is necessary, it should either be added in the "flags" field of the AVMotionVector structure, or in another side-data. This commit also includes an example exporting them in a CSV stream. 2014-07-16 14:42:42 +00:00			`extract_mvs \`
