4

So basically I couldn't find an answer to this directly. But can a Pi 4 blu ray play blu ray rips(from my own blu rays) without issues? With the pi 3 and older, it was too much. Is the pi 4 powerful enough?

Thanks in advance,

Bunsen

    Try it, you won't break anything.

    Depends on what player you use. omxplayer is capable of playing 1080p with no significant CPU usage. But RPi 4 is not supported yet.

It will be enough, but the performance will depend on the codec used:

  • HEVC, H.265 and H.264 are supported in hardware, so those will offer the best performance with a compatible video player such as VLC.

  • Older formats such as MPEG-2 are decoded in software, which is fine in most cases. Videos with high bitrates (such as Blu-ray) will result in significant CPU load though.

Early Blu-ray disks use MPEG-2 codec natively, so the playback of such raw BD rips (.M2TS files) on the RPi 4 will rely on a software codec. More recent Blu-ray (.M2TS) and AVCHD rips (.MTS files, DVDs for Blu-ray players) use H.264 and will be decoded in hardware on an RPi 4.

If your rips are transcoded (so you have made .AVI/.MKV/.MP4 files instead of .MTS/.M2TS), the original codec is not important. Be sure to pick one of the hardware-supported codecs when transcoding.

Note that if you need post-processing during playback (e.g. playing a 3D Blu-ray as 2D on a regular screen), hardware decoding will not work regardless of the codec (at least in VLC). Playing a full HD 3D H.264 stream in 2D with software decoding is about as much as an RPi 4 can handle, that is, the playback is not always smooth and there is some frame drop.

    "Blu-ray disks use MPEG-2 codec natively" - this is not quite correct. Only very early Blu-Ray releases used. Most blu-rays use H264. Furthermore, your assumption that .m2ts always contains MPEG-2 is incorrect; it can contain H264 streams too (and in fact, in my experience this is the most common format). en.wikipedia.org/wiki/Blu-ray en.wikipedia.org/wiki/.m2ts

Of course Pi4 can play a bluRip file. But you have to notice 2 things: 1. Do not keep open other processes while playing videos 2. Use a good HDMI cable and a good power source

  • You mean play it fine, or play it like it does on pi 3?

  • I tried some videos on pi4. AVI formatted files doesn't work very well. But MKV format is ffine. MP4 too Nov 1, 2019 at 13:05
  • Those are blu ray rips? I have a pi2 and a pi3 as media centre, and both do not like blu rays, the rest of the files are not a problem.

It is very good question, on rpi 1-2-3 i use special license keys to unlock hardware ecoding MPEG-2 and VC-1. But on rpi4 hardware decoding of MPEG-2 and VC-1 not supported. http://www.raspberrypi.com/mpeg-2-license-key/ http://www.raspberrypi.com/vc-1-license-key/

  • Since the poster specifically stated they have a Pi 4, why post an answer which applies to anything but Pi 4? Jan 9, 2020 at 9:49
