An alternative would be on the server side, dumping each frame out as an image, and then just stepping through the video via images rather than trying to get a video player to work frame by frame.
Here's an ffmpeg command line to dump frames out of a video, to get you started:
If you wanted to get fancy, you could try using a video player for playing the video, and then when you stop and want to step by frames, replace it with a frame-by-frame view implemented using images. This would take a bit more work to convert video times to frame numbers when you pause the video, but may give you what you need.

另一种选择是在服务器端，将每个帧转储为图像，然后通过图像逐步浏览视频，而不是尝试让视频播放器逐帧工作。
下面是一个用于从视频中转储帧的
ffmpeg命令行，以帮助您入门：如果你想变得更奇特，你可以尝试使用视频播放器来播放视频，然后当你停下来并想要逐帧播放时，将其替换为使用图像实现的逐帧视图。当您暂停视频时，这需要更多的工作才能将视频时间转换为帧数，但可能会满足您的需要。
