- To convert an avi file to rmvb using mencoder try:
mencoder "src.avi" -o "dest.rmvb" -ovc lavc -lavcopts vcodec=mpeg4 -oac mp3lame
If real player fails to play generated file, then play it using mplayer. - To cut an avi file (5 seconds is the total length to cut), use following command:
mencoder -ss 00:10:10 -endpos 00:05:00 -ovc copy -oac copy "src.avi" -o "dest.avi"
Performance Tuning of Kafka is critical when your cluster grow in size. Below are few points to consider to improve Kafka performance: Consumer group ID : Never use same exact consumer group ID for dozens of machines consuming from different topics. All of those commits will end up on the same exact partition of __consumer_offsets , hence the same broker, and this might in turn cause performance problems. Choose the consumer group ID to group_id+topic_name . Skewed : A broker is skewed if its number of partitions is greater that the average of partitions per broker on the given topic. Example: 2 brokers share 4 partitions, if one of them has 3 partitions, it is skewed (3 > 2). Try to make sure that none of the brokers is skewed. Spread : Brokers spread is the percentage of brokers in the cluster that has partitions for the given topic. Example: 3 brokers share a topic that has 2 partitions, so 66% of the brokers have partitions for this topic. Try to achieve 100% broker spread...
