Hi guys, I'm working on a project that uses FFMPEG to fetch still images from a live RTSP video stream and save them to disk. I am using the assemblies aformat/codec-55.dll and the development headers and libs for compilation from ffmpeg-20131120-git-e502783-win64-dev. The whole project is compiled using Managed C++ (Cpp/cli) .NET 4.0 for 64-bit.
I have spent some time creating a simple demo, which all seems to work well with the exception of all the images that are saved are plain black. I have pointed my example to an inline video stream of Big Buck Bunny: rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov - But the images are always black. Opening the image shows nulls so I think somewhere the video frames aren't being decoded correctly, or I am doing something silly to wipe out the frame data..? I have tried various things and followed various examples, though lot of the tutorials out there are using deprecated method calls. I hate to paste giant blobs of source code, but it's probably the best way; I really need to get this working soon and would be eternally grateful to anyone who can provide some assistance! Here is the example code: http://pastebin.com/ziYcWaYX Many thanks in advance for your time. Kind regards, -Tom
