Research direction
Start by reproducing the behavior in the sample C# and C++ applications with an H.264 video and the force options enabled, then compare it with FFplay using the same FFmpeg versions. Check memory growth, startup delay, and pauses while varying buffertime; done means playback starts promptly and continues without recurring pauses.

Description
Do:
- Used the sample C# and C++ applications
- Play a H.264 video with the force option(s) set to true
See:
- Memory starts to climb (similar to #97, I guess) and it takes a few seconds for the video to start playing
- At this point the memory starts going down
- After a few seconds (the buffer time?) the video stops playing and the memory goes up again
- This continues to happen throughout the videos I tested
Remarks:
- A MOV video with a different codec (but which as a result also uses the uncompressedsampleprovider) doesn't have this behavior
- FFPlay of the same version plays the video without problems
- Tested with ffmpeg 3.3.3-1 and 3.4
- Changing the buffertime has an impact in the delay of the pauses, but they still occur
