[Mlt-devel] thumbnail creating hint

[Maksym V. <ve...@m1...>]

Hi,

i have a problem creating thumbnail from videofile.

*melt* command line works fine:

/usr/local/mltframework.org/mlt/bin/melt -profile dv_pal R0009178.mpg 
in=100 out=100 -consumer avformat:R0009178.png s=128x72 vcodec=png f=image2

but program code sample do not work properly:

#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
#include <string.h>
#include <errno.h>
#include <framework/mlt.h>
int main(int argc, char** argv)
{
     mlt_consumer consumer;
     mlt_producer producer;
     mlt_profile profile;
     mlt_properties c_props, p_props;

     if(3 != argc)
         return 1;
     mlt_factory_init(NULL);
     profile = mlt_profile_init("dv_pal");
     producer = mlt_factory_producer(profile, NULL, argv[1]);
     consumer = mlt_factory_consumer(profile, "avformat", argv[2]);
     c_props = mlt_consumer_properties(consumer);
     p_props = mlt_producer_properties(producer);
     mlt_properties_set_int(p_props, "in", 100);
     mlt_properties_set_int(p_props, "out", 100);
     mlt_properties_set(c_props, "s", "96x72");
     mlt_properties_set(c_props, "vcodec", "png");
     mlt_properties_set(c_props, "f", "image2");
     mlt_consumer_connect(consumer, mlt_producer_service(producer));
     mlt_consumer_start(consumer);
     while(!mlt_consumer_is_stopped(consumer)) usleep(40);
     mlt_consumer_stop(consumer);
     mlt_consumer_close(consumer);
     mlt_producer_close(producer);
     mlt_profile_close(profile);
     return 0;
};

it output always first frame, so setting in/out does not help... any hint?
