Can HLS take advantage of any GPUs for the transcoding?<br>
</blockquote>
<br></div>
Not at present, no. Nearly all existing GPU transcoding tools are proprietary, and only amount to rather modest performance and quality compared to x264 and a decent CPU. I haven't been paying close attention, but I'm not aware of any production-ready open source GPU encoding projects. The only other options are things like Elegato's encoder dongle, which does not have Linux drivers, and **** Intel's QuickSync, which similarly does not have publicly available Linux drivers *****.</blockquote>
