Question

I have tried to compile ffmpeg with the new flascc compiler with the following parameters ( I set only h263 ability as a test):

PATH=/cygdrive/c/download/flascc/sdk/usr/bin:$PATH ./configure --enable-static 
--disable-shared --extra-libs=-static --extra-cflags=--static --disable-doc  --disable-ffplay 
--disable-ffprobe --disable-ffserver --disable-avdevice   --disable-avfilter   
--disable-pthreads  --disable-everything --enable-muxer=flv 
--enable-encoder=flv --enable-encoder=h263 --disable-mmx --disable-shared   
--prefix=bin/  --disable-protocols --disable-network --disable-optimizations --disable-debug 
--disable-asm --disable-stripping 
--prefix=/cygdrive/c/download/flascc/sdk/usr

Then I tried to make as follows:

PATH=/cygdrive/c/download/flascc/sdk/usr/bin:$PATH make

PATH=/cygdrive/c/download/flascc/sdk/usr/bin:$PATH make install

*.a files have been created in the subdirectories, like: libavcodec.a. But how can I create an .swf/.swc from the *.a files?

Thanks!

In the docs it says you can produce SWFs with -emit-swf

To generate a SWF, the executable format suitable for use in the Flash
Runtime, you pass the -emit-swf argument to GCC:

gcc -emit-swf hello.c -o hello.swf

and SWCs with -emit-swc

-emit-swc= Emits a SWC that can be linked into a Flash Builder project or distributed for others to link into their own projects. You must
specify the namespace that you want to use to replace the default
com.adobe.flascc namespace, this lets you link multiple
FlasCC-generated SWCs into a single project.

Note that you’ll need to write some kind of shim layer api for your AS3 code, or you can automate it with SWIG.
