video-processing

I am using ffmpeg.exe to convert video files to flv format . For that purpose i use a windows service to run the conversion process in background . While trying to convert large files (i experienced it when the file size is >14MB) through windows service it gets stuck at the line which starts the process (ie, process.start(); ). But when i tried to execute ffmpeg.exe directly from command prompt it worked with out any problems. My code in windows service is as follows: private Thread WorkerThread; protected override void OnStart(string[] args) { WorkerThread = new Thread(new ThreadStart

I'm trying to modify the motion detection part of FFMPEG. What I want to do is to extend the search space, so that whenever the macroblock hit the right most edge of the frame, I need it to still move the block towards the left-most as if they are connected (in my example videos, the right edge is actually a continue of the left edge). Can someone help me to point where exactly I can modify it within FFMPEG source code or x265, or x264? I took H265 as an example from here . It has a motion.cpp file which nicely specifies the possible block sizes as below. But I can't find the specific loop
