ADALM-PLUTO with F5OEO firmware "FIRM2201RC" (beta-for-the-brave).FFMPEG 4.2.2 Windows 64-bit Static (the shared libs version will work too).OBS Studio 24.0.3 (64 bit) at Windows 10. This solution works fine for me with SR125, a 384x306 image size with 12 FPS and 12kHz mono audio and i would say the quality is some kind of "crispy clear" compared to the same conditions encoded with H.264. But it doesn't and OBS doesn't show a "libx265" selection in the dropdown (like the "libx264").Ī inquiry at the OBS forum wasn't succesfull, those guys live in their "4K-Twtich-Youtube" world and claimed, that H.265 software encoding will not work because of the CPU load (although i explained the background and that i want to use very low bitrates).Īnyway, until my HDMI/H.265 encoder arrives from China, i searched and found a solution to create a H.265 encoded stream for the Pluto with software encoding. My expectation was, that in case of no HW support this encoder uses software encoding through "libx265" which FFMPEG should support. Now that i saw what H.265 can do, I tried to get the "nvenc_hevc" encoder working in OBS, but it seems, that this set needs hardware support, which my NVIDIA GT650M can't offer. Because of my limitations of RF power (about 20W) and dish size (about 73cm) I am bound to lower DATV bitrates (<=125kBit/s), but it works so far to send moving images via QO-100. The last weeks I played around with OBS, H.264 encoding and streaming via RTMP to my Pluto.
