So what I did to judge about the video quality was comparing two videos side by side with mpv. That said I’m by no means a video encoding expert and my main focus just was to keep the same “visual” quality when converting from the MPEG-2 streams in H.264 to H.265 and reduce the size of the original recording by about 50%+. Without expecting to much I played around a bit and the outcome was surprisingly good - and with way less power needed! So I knew that my AMD RX 5700XT GPU supports H.265 hardware encoding. This works quite well but uses quite some power. First I used my CPU AMD 3900X for this task. And of course it should be fast and maybe even power efficient. I was wondering how to shrink these kind of videos without lowering the “visual” quality too much. This is quite a lot if you want to archive your videos.
So for an hour of video it could take easily around 6 GByte on disk. Most public TV channels (via satellite) in Germany that I’m interested in are using MPEG-2 streams with H.264 encoding with a bitrate of about 10000-16000 kb/s. Here is a prebuilt image to get you started: įor the source code use the github links in the first link.I’m using VDR for TV recording. Of course, you don't need to use Kodi to use ffmpeg, but since this is open source, you could start with it because many decoding solutions for all the codecs have been figured out + all the audio decoding and bitstreaming is in there too. This is a problem because you get a frame drop every 42 seconds = 42. So far freescale haven't provided linux kernel to make a sync rate of 23.98 - only 24fps is available. I have still to find a working 1080p 23.976 fps (which is an industry standard Blu Ray encode rate). This is to be expected - even a quad core intel i5 haswell has stuttering.
HEVC/H265 - decodes but not watchable because too much frame stuttering. Needed a different solution: Deinterlacing feature Even the single core im圆 with GC800 can play with higher than BluRay encoding quality.ġ080i interlaced at 50/60fps. The latest ffmpeg with h265 support is included in Kodi software, which you can just image onto micro SD card: Using FFmpeg, can the i.MX6 decode and play an incoming 1080p60 stream (HEVC/H.265/H.264/MPEG2)?
