    Interestingly I am getting about equal 1080p playback performance with local videos on my X5000/020 under AmigaOS 4.1 FE with Emotion video player and the composite comp_yuv2 output with a Radeon R9-270X and under Linux using a Radeon FireMV 2260 pciex1 in a pciex1 slot with hardware assisted video playback. I am able to playback 1080p avi and mp4 videos with frame skip enabled . 1080p mkv's are a problem for both OS'es .
    720P playback is better with the same setup under Linux. Youtube videos can be streamed ok.

    Cool.

    At least we know the 64 bit hardware will perform reasonably well.
    1080p mkv performance seems to vary from file to file on a G5, but again 720p is consistently good.

    As on the A1222, its fair to say that a T10XX cpu based solution might have had issues with higher resolutions as well (although it would have some edge).

    And to be a complete trouble maker, even without UVD, even limited to a single thread, a Power 9 cpu ought to be able to handle 1080 mkv files.

    Hardware is where it's at for decoding video, I'm afraid. Throwing your CPU at them is a losing battle.

    I've got an old media player based on a 300 MHz MIPS CPU and 90 kB of RAM, which plays 1080p videos of almost any codec, bitrate or container with its Sigma decoder chip. MKV Blueray rips? No problem, as long as the bitrate isn't insane or they don't use some weird codec like Hi10P.

    The RaspberryPi can play almost all the same 1080p just fine, assuming the I/O bottleneck doesn't get in the way. The Pi 3 can handle 60 mbit bitrate 1080p video no problem. Again, due to hardware support built into the Broadcom SoC.

    Same with an old Android box with an Allwinner A10 Chinese ARM ripoff I own: single core, 1 MHz, plays 1080p fine, even across a LAN; the Mali GPU does the hard work, or at least I think it's a Mali.

    Software only, an i5 or even a slow i7 might struggle to play the same videos without hardware support. It's becoming ludicrous, because any graphics card or APU within the last decade should be able to play 1080p, and here we are with people running out and buying the best spec Radeons supported, that they'll never use even the basic hw codec support on.

    Basically, yeah, that about sums it up.
    Without full documentation of the decoding hardware we have to rely on porting an existing solution, or use the cpu.

    The Pi has one of the few fully documented gpus used on an ARM cpu.
    Android and proprietary Linux drivers on other systems rely on code provided by the hardware manufacturers.

    Same with Windows and MacOS.

    Even with the hardware UVD support on PowerPC under Linux there appears to be a problems with 1080p decoding . At least on the X5000/020 . I was not seeing any better performance with a Radeon HD6570 in the pciex16 slot as the FireMV 2260 in a pciex1 slot. Issue could be in hardware or software.

    Under AmigOS 4.1 the higher end cards give a boost with video playback with the composite comp_yuv2 output. Also the Polaris cards have a much better composite performance for larger rectangle sized manipulations(Have not tested video playback on the X5000/020). A couple of 5% increases in performance such as the Radeon HD 3.x driver and a video card that has a better composite performance makes a big enough difference to be able to play 720P video well without altivec on the X5000/20.

    Edit: I am also getting decent performance with 1080p MP4 videos .

    That was an interesting 5 minutes read through the last few posts. As an end user the thought wouldn't even pop into my head that there might be a debate about how well a £1700+ computer (X5000) could play video in 4K, let alone 720p or 1080p. Frankly, I wouldn't expect there to be an issue on the cheaper A1222 either, although maybe not 4k. Fortunately I don't have any 4k screens but that won't be the situation forever. Windows is already a major pain when it comes to mixed scaling so it had occurred to me to get a 4k monitor. Of course that alone doesn't mean I need to play video at that resolution of course!

    I was going to pull the trigger on a Tabor the minute they were available because I've always wanted an OS4 system but am not prepared to shell out for the X5000. This thread has certainly made me question that.

    Unless you plan to use any Amigaoid powerpc system and OS as your only system then you should not use the video playback yardstick as the only criteria. I enjoy my Sam460ex + AmigaOS as well.

    Video playback would be seen as this machines weakness.
    I watch a lot of videos on this machine.
    I just re encode them to a smaller xvid avi format at high bit rate using a PC and transfer them to the Sam460ex via FTP. Quality of the playback with these is excellent.
    About 6 Minutes to convert a 45 minute video and can do 5 videos at a time.
    The default playback quality using emotion video player on the Sam460ex is much nicer than on the basic PC setup.

    I am starting to experiment with complete videos 40+ minutes rather than just short clips.
    Seem to be able to play back 1080p mp4 without frame skip enabled in Emotion video player.
    Will verify and report back .

    You mean the higher-resolution video on the PC looks worse than the lower-resolution video (re-encoded from the higher-resolution one) on the Sam460? How does this make sense?

    Not trying to rain on your parade, but I'm sure you recall our tests and discussions on AW.
    You refer to mp4, but that's just a container.
    Mplayer verbose readout for codec shows mpeg-4 in your posts. That's the codec.
    That is a lower stress codec inside the mp4 container.
    Since the majority of all 1080p are encoded with codec h264, I still think for practical purposes you should do your testing with -that- codec.

    Don't worry about rain. as long as I can have Tanks in my parade too .

    My MP4's codec = VIDEO: [MP4V] 1920x1074 24bpp 23.976 fps 1991.8 kbps (243.1 kbyte/s)
    Can play these .This CODEC is Handbrakes default conversion settings .

    Original mkv = VIDEO: [H264] 1920x1074 0bpp 23.976 fps 0.0 kbps ( 0.0 kbyte/s)
    Cant decode fast enough. So blocky video and periodic stuttering audio .

    Hmm, I'm not sure the codec is really what is making the difference here. A video bitrate of 2000 kbps is quite low for a 1080p. I have quite a few that are 8000 kpbs - size anything from 4 to 8 GB. 2000 kbps tends to be more common for 720p (although YouTube 1080p tends to be around 2000 kpbs, to be fair).

    Anyway, it looks like you're able to play the converted file because you're literally processing a quarter of the data than the original file. Have you looked at keeping the bitrate and reducing the resolution to 720p? It might look just as good yet put less strain on your graphics bus.

    That bitrate should be much more like the original mkv file quality, I think. (It's hard to say as I don't know the original, as it was listed as 0 kbps. I've seen that before though. It's apparently difficult to get encoding tools to show bitrate of an MKV file).

    Does it play alright?

    Edit: Yes it does. I just can't read. Must indeed be the codec.

    In comment #82, you wrote that it's not better with your HD6570.
