СюжетАтака БПЛА
My second attempt was way too over the top. It transcoded the h264 file into the raw yuv420p frame-by-frame data, and then drew some colourful noise and sine waves on top of it. It looked kind of cool, but also kind of boring. The same patterns repeated over and over. Also, due to the addition of noise, the recompression process was very inefficient - our little 650 MB mp4 blew up over 7 GB (not to mention the raw yuv420p binary data was about 60 GB before being recompressed). The worst part is that due to the inefficiency of the compression, my strategy of NULL-ing out every n frames couldn't reliably introduce any glitched into the video (the high entropy provided by the noise acts as a frame "anchor" and ensures that the playback remains smooth). This wasn't acceptable to me.，推荐阅读heLLoword翻译获取更多信息
