libavdevice-dev \
libswscale-dev
+With libav/ffmpeg version previous than 0.9 this patch is needed:
+http://git.ao2.it/libam7xxx.git/blob_plain/refs/heads/debian:/debian/patches/0001-Revert-am7xxx-play-switch-to-avcodec_encode_video2.patch
+
The library and the example programs can be compiled following these steps:
$ git clone git://git.ao2.it/libam7xxx.git
$ cmake -D CMAKE_C_COMPILER=cgcc ../
$ make
+And for a pre-release check with a different compiler, which never hurts:
+
+ $ mkdir build
+ $ cd build
+ $ cmake -D CMAKE_C_COMPILER=clang -D CMAKE_BUILD_TYPE=debug -D STRICT_COMPILATION_CHECKS=ON ../
+ $ make
+
