We believe that we are running out of video RAM in a Linux based system that we are working on. We are seeing video & graphic drivers segment faulting with allocation related errors. Are they any tools or techniques that we can use to determine how much video ram is free at any given point in time? Either an external application or so...
Hi, I'm converting MP4 videos to FLV using ffmpeg-php on my CentOS server (without intervention from flvtool2 because it's not installed). The FLV videos are created, but no player is capable of retrieving the video duration, this creates serious issues when trying to seek the video. I'm using the player created by Moyea's Flash Video M...

They deal with modifying a video stream while it's playing, and I remained pleasantly impressed by the accuracy and smoothness of this technique. Out of all these presentations, I considered one of them quite fascinating in terms of text ...
Is there a way of constructing a IAMTimeline object by loading a video file directly? I know how to build a filter graph, insert and remove filters, reconnect pins etc., but I need to use some functionality exposed by the IAMTimeline interface.
