Box 1:AX (Opticum) 4K HD51How to transcode H.264 video to H.265 Using ffmpeg on OpenATV?
Good day!
I install ffmpeg and want to use it to transcode my h264 video files to h265 format. I took the command asffmpeg -i input.mp4 -c:v libx265 -preset medium -x265-params crf=28 -c:a aac -strict experimental -b:a 128k output.mp4
Is it even possible? How to transcode H.264 video to H.265 Using ffmpeg on OpenATV?

Box 1:Vu+ Zero 4KBox 2:Vu+ Solo SE V2Box 3:Formuer F4-TURBOYes... because in your ffmpeg, on your OpenATV... there is no H.265 software codec. You can check it by the command-line:
Code:ffmpeg -codecs | grep -E "264|265" # ..or.. : ffmpeg -formats | grep -E "264|265"

Box 1:hd51Box 2:vuduo4kseBox 3:und noch 20-30 andereThe hd51 has no h265 encoder. So whole process is done in software. If you want to convert a 1-2 hour movie I guess it will take days!
hd51, vuduo4se,....

Box 1:Vu+ Zero 4KBox 2:Vu+ Solo SE V2Box 3:Formuer F4-TURBOAs @betacentauri writes, there is no hardware support for H.265 in your device. Unfortunately the mipsel/arm processors are not suitable for rendering or transcoding in real time, as there is no hardware en/decoder. It would take a very long time. Use a desktop PC for this purpose.
Of course, the HEVC software support library/module could be added (libx265), but it will be very inefficient. Obviously, this is done by compiling ffmpeg with the support of libx265 for your chipset and your Enigma2. Some smartphones have a higher computing power (better chipset) than set top boxes ;-).Geändert von s3n0 (14.04.2019 um 09:51 Uhr)
