I though the issue might be related to the step where the c++ examples append an endcode set of bytes to the file but that hasn't fixed it.Īny guidance on what steps I'm missing to turn the output into a 'valid' video would be greatly appreciated. I have build and run the Example project and can see the same issues with the video it produces from the Bunny video it first decodes then encodes to H264. It's like VLC is lagging at the start for some reason

it plays back weird, as if the first few seconds are all the same frame then starts playing what appears to be some of the frames I'd expect.

VLC is unable to detect the video length or show current time.

it only plays in VLC, is there another AVPixelFormat I should be using for the destinationPixelFormat so that anything can play?.

I've changed H264VideoStreamEncoder a little based on ffmpeg's own c++ examples because they had a few things it seemed the C# example was missing but that hasn't made any difference. It produces a file I'm calling outputFileName.h264 just fine, no errors, colors are correct but the video plays back strangely. I capture a bunch of frames into textures and feed them into Encoder.EncodeImagesToH264.

I've taken the FFmpegHelper, VideoFrameConverter, H264VideoStreamEncoder classes straight from the, rolled my own FFmpegBinariesHelper class and Size struct and mangled the EncodeImagesToH264 from Program.cs to look like the below code snippets.
