Ffmpeg h265 encoding12/17/2023 ![]() ![]() Or is there a trick to get the integrated ffmpeg encode recordings in H.I decided to run some tests using my GoPro time lapse program to see how much compression I’d get versus how much extra time for encoding.įirst I had to read up on the settings for using h.265 in FFmpeg. It would be really great to have libx265 selectable at the recording encoders of OBS. The H.264 works fine, but the H.265 saves a lot of precious bandwidth. The bandwidth of the DATV transponder is only 8MHz and the transmit power of a ground station is only some ten watts into a dish, so the transmissions are made with bitrates of 2MBit/s down to 33kBit/s.Įspecially for the lower bitrates over the air, the stream bitrates have to be very efficient. I know, that the generic ffmpeg (latest version) works fine with "-vcodec libx265", because i worked around this issue by recording via UDP to a local instance of a generic ffmpeg to transcode from H.264 to H.265.īackground for that is, that a lot of radio amateurs use OBS to generate video streams to send them as "Digital Amateur Television" DVBS2 coded to the new geostationary satellite QO-100. Why isn't there the choice for libx265 in OBS? Is the OBS integrated ffmpeg not prepared/compiled for that? It seems, this encoder needs hardware support to work, but my GT650M can't do that, so i expect OBS/ffmpeg to use the software encoder libx265 instead.
