Hello,
can anybody suggest a solution to avoid memory leak on linux using
following code ?
while(bRunning) {
m_mltRepo = mlt_factory_init( NULL );
m_mltProfile = mlt_profile_init( m_strProfile.c_str() );
m_mltProducer = mlt_factory_producer( m_mltProfile, m_strProducer.c_str(),
pClipCurrent->path().c_str());
m_mltConsumer = mlt_factory_consumer(m_mltProfile, m_strConsumer.c_str(),
chArg);
mlt_properties mltPropertiesConsumer =
MLT_SERVICE_PROPERTIES(MLT_CONSUMER_SERVICE(m_mltConsumer));
mlt_properties_set_int( mltPropertiesConsumer, "buffer", m_iBufferSize );
mlt_properties_set_int( mltPropertiesConsumer, "prefill", m_iPrefillSize);
mlt_properties_set_int( mltPropertiesConsumer, "terminate_on_pause", 1 );
mlt_consumer_connect( m_mltConsumer, MLT_PRODUCER_SERVICE( m_mltProducer )
);
mlt_consumer_start(m_mltConsumer);
//wait while playing
Sleep(....)
mlt_consumer_stop( m_mltConsumer );
mlt_consumer_close( m_mltConsumer );
mlt_producer_close( m_mltProducer );
mlt_profile_close(m_mltProfile);
mlt_factory_close();
}
Without terminate_on_pause I cannot detect end of current clip if I have
for example 20sec buffer, because
mlt_producer_get_playtime(m_mltProducer); stops after buffer is filled, but
it has not been shown fully.. Maybe there is better solution to this?
But the main problem is that after mlt_factory_close does not clear out
memory on linux. If I use mlt_pool_purge() it cleans out memory, but
virtual memory still grows fast. The problem can be detected if you run
5-10 large video clips one by one. Does anyone has ideas about what is
wrong with this code?
If I do not close consumer it makes decklink consumer to lag & twich after
some while, but if I reset it every time then it is working fine, except
memory leak of mlt.
