1 FFmpeg currently uses a custom build system, this text attempts to document
2 some of its obscure features and options.
7 Disable the default terse mode, the full command issued by make and its
8 output will be shown on the screen.
11 Destination directory for the install targets, useful to prepare packages
12 or install FFmpeg in cross-environments.
17 Default target, builds all the libraries and the executables.
20 Run the fate test suite, note you must have installed it
23 Will list all fate/regression test targets
26 Install headers, libraries and programs.
28 libavformat/output-example
29 Build the libavformat basic example.
31 libavcodec/api-example
32 Build the libavcodec basic example.
34 libswscale/swscale-test
35 Build the swscale self-test (useful also as example).
38 Useful standard make commands:
40 Touch all files that otherwise would be build, this is useful to reduce
41 unneeded rebuilding when changing headers, but note you must force rebuilds
42 of files that actually need it by hand then.
45 rebuild with multiple jobs at the same time. Faster on multi processor systems
48 continue build in case of errors, this is useful for the regression tests
49 sometimes but note it will still not run all reg tests.
