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. – Dougie Oct 25 '19 at 10:15

    Depends on what player you use. omxplayer is capable of playing 1080p with no significant CPU usage. But RPi 4 is not supported yet. – kwasmich Oct 25 '19 at 10:36

    @Dougie, I can't try it if I do not have it yet ;) others thanks – Dr_Bunsen Nov 1 '19 at 11:40

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.

Blu-ray disks use MPEG-2 codec natively, so the playback of raw BD rips (.M2TS files) on the RPi 4 will rely on a software codec. AVCHD rips (.MTS files), which are 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.

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? – Dmitry Grigoryev Jan 9 at 9:49

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? – Dr_Bunsen Nov 1 '19 at 11:41
  • I tried some videos on pi4. AVI formatted files doesn't work very well. But MKV format is ffine. MP4 too – Sohan Arafat Nov 1 '19 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. – Dr_Bunsen Nov 5 '19 at 15:37
