filtering video with other thread than videothread #160

Open debosvi opened 10 years ago

debosvi commented 10 years ago

Hi wangbin,

Today I used to register some video filters and it works well. I have unfortunately one filter that takes very long time (close to my frame rate) to process and can't be delayed in another thread due to your actual implementation..

How can I do to set filtering process asynchronously to video thread before sending to output?? In the best way we can have video thread and filters performing in 2 different thread!!

best regards,

now you can't do it. I have to change the code to support filter thread.
