and the ouput is: Video I/O:įrom what I understand from this log FFMPEG is installed and detected by OpenCV after which I compile the jar with the command make -j10 and it runs successfully with no single error but even after all this OpenCv does not play video files, but it does work with the WebCam.I am really lost and very new to OpenCV in Linux so please if there is anyone who knows what could be the problem help me sort it. I pass the data to OpenCV with the subprocess module. Searching for an alternative as OpenCV would not provide timestamps for live camera stream (on Windows), which are required in. Meaning FFMPEG was not installed but when compiling the Jar I configure CMAKE like cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local. Im Kind of late, But Ive created this powerful VidGear Python Library automates the process of pipelining OpenCV frames into FFmpeg on any platform. Im using FFMPEG to read the file or stream as OpenCV does not retain the klvdata.
I have manage to compile the Jar but having issues playing a video, I get the error Unable to stop the stream: Inappropriate ioctl for device from what I understand it is something to do with Video I/O when I call the method Core.getBuildInformation() it gives me the following output: Video I/O: Video Transcoding YouTube-Style with ffmpeg posted by Jonathan Lathigee.
#Ffmpeg python linux image2pipe to opencv windows#
I have been using OpenCV on Windows for a year now and recently transitioned to Linux, Life has not been easy, from loading an already existing Jar file to compiling my own.
