Can I use GPU to accelerate/handle multiple streams to use muxer converting from SRT to HLS?

Question

Hi,

I have multiple devices publishing to mediamtx server hosted on a VM in GCP in SRT/RTMP and I am consuming HLS for browser. As there are multiple streams being trans-coded, to optimize it Can I use a GPU or hardware acceleration to achieve it?

Hello, if the only conversion you are performing is remuxing from SRT/RTMP to HLS, then you don't need to accelerate the operation since it requires a minimal amount of CPU. The bottleneck is usually the network bandwidth, not the CPU.

Hardware acceleration can help only if you are using FFmpeg or GStreamer to re-encode the stream, i.e. switching codec or recompressing it. In this case, you can use the enable hardware-accelerated FFmpeg / GStreamer encoders (for instance h264_nvenc for FFmpeg and nvh264enc for GStreamer), there are several guides available online.
