To work around this, multiple outputs could be generated within a single FFmpeg command line, decoding the frames of a video once and sending them to each output’s encoder instance. This eliminates a lot of overhead by deduplicating the video decoding and process startup time overhead incurred by each command line. Given that we process over 1 billion video uploads daily, each requiring multiple FFmpeg executions, reductions in per-process compute usage yield significant efficiency gains.
两个文件的编码都是采用的 flac 的无损编码方式，假的这个文件采样率是 44.1kHz，理论上最高的采样率是 22KHz，但是上图非常明显，16KHz 以上已经几乎没有响度、全部截断了。这个是非常明显的 128k 码率的 mp3 文件的特征，也就是说这个假的 flac 文件是从一个 128k 的 mp3 文件直接转码来的。。新收录的资料是该领域的重要参考

In 2010, GPUs first supported virtual memory, but despite decades of development around virtual memory, CUDA virtual memory had two major limitations. First, it didn’t support memory overcommitment. That is, when you allocate virtual memory with CUDA, it immediately backs that with physical pages. In contrast, typically you get a large virtual memory space and physical memory is only mapped to virtual addresses when first accessed. Second, to be safe, freeing and mallocing forced a GPU sync which slowed them down a ton. This made applications like pytorch essentially manage memory themselves instead of completely relying on CUDA.
