codec_names.h is automatically generated, its absence from the source tarball is normal. Can you post your failing build log? More specifically, from a clean configured tree (make distclean; ./configure), the full output of the following command:

make V=1 libavcodec/utils.o

Also, please try to reproduce with current git head.

Tnx for a quick answer.

I can't to give you output of

make V=1 libavcodec/utils.o

since I build ffmpeg together with all andoroid sources. By this reason I made a some tricks in build scripts.

Seems my tricks don't use

Let's close it as not a bug.

Status: newopen

If you tweaked the build system for the 0.8 series, then indeed you will probably need to adapt it to the new features of 0.9, including codec_names.h. The part concerning codec_names.h is at the end of libavcodec/Makefile. Basically, it amounts to:

cc -E libavcodec/avcodec.h | libabvcodec/ config.h libavcodec/codec_names.h

but of course with the bunch of compiler flags.

Feel free to reopen the bug if it happens that the original build system fails.

Tnx a lot, I found a Makefile that does it.

Resolution: invalid
Status: openclosed

I believe I have seen this broken script before, allow me to repeat that it is not a good idea to use it.

If you believe FFmpeg's build system is missing features, please report it as a new enhancement ticket.
