Mlt on Win32

Using SDL:

VM@VM-PC MSYS ~/mltBuild/mlt/build
$ gcc test.c -lmlt -L/c/msys32/home/VM/mltBuild/mlt/build/lib && ./a.exe
start
Creating consumer 003B67E0
Creating producer 002ED260
Connecting 002ED260 to 003B67E0
Starting consumer 003B67E0
Wait for consumer
Wait more for consumer...
Wait more for consumer...
(... forever. SDL window is spawned but is unresponsive, using 1 full cpu core)

// Let's say maybe it is a problem with SDL on windows. Using avformat. Pointing to valid file and valid writable directory.

mlt_consumer consumer = mlt_factory_consumer(NULL, "avformat", "C:\\msys32\\home\\VM\\mltBuild\\mlt\\build\\OUT.mp4");
mlt_producer producer = mlt_factory_producer(NULL, "avformat", "C:\\msys32\\home\\VM\\mltBuild\\mlt\\build\\test.mp4");

$ gcc test.c -lmlt -L/c/msys32/home/VM/mltBuild/mlt/build/lib && ./a.exe
