• This version adds a lot of Dolby Vision related improvements, as well as some other improvements. • New feature: Dolby Vision decoding and output is now supported also when playing all other popular file formats: • MKV P7 FEL single-track (dual-layer) • MP4 P7 FEL single-track (dual-layer) • TS P7 MEL/FEL single-track (dual-layer) • TS P4 MEL/FEL single-track (dual-layer) • MP4 P7 FEL dual-track • MP4 P7 MEL dual-track • Dune HD media players now have the widest support for Dolby Vision file formats among all existing media players (all popular formats supported by any other media player are supported, and no other media player supports as many formats). The list of supported Dolby Vision file formats now includes: • Blu-ray disc images: • BDMV (Menu mode) P7 MEL/FEL • BDMV (Lite mode) P7 MEL/FEL • BD ISO (Menu mode) P7 MEL/FEL • BD ISO (Lite mode) P7 MEL/FEL • M2TS files: • M2TS P5 • M2TS P7 MEL/FEL dual-track • M2TS P8 • TS files: • TS P4 MEL/FEL single-track (dual-layer) • TS P5 • TS P7 MEL/FEL single-track (dual-layer) • TS P8 • MKV files: • MKV P4 MEL/FEL single-track (dual-layer) • MKV P5 • MKV P7 MEL/FEL single-track (dual-layer) • MKV P8 • MP4 files (this also includes MOV files): • MP4 P4 MEL/FEL single-track (dual-layer) • MP4 P5 • MP4 P7 MEL/FEL single-track (dual-layer) • MP4 P7 MEL/FEL dual-track • MP4 P8 (this includes support for iPhone Dolby Vision MOV P8.4 files) • NOTE: In all cases, Dolby Vision extended information from the file is used and output to TV, i.e. it is a real playback of Dolby Vision video. • New feature: Dune HD Dolby Vision Purifier engine. It optimizes and remuxes Dolby Vision video on-the-fly to make it as compatible with Realtek RTD1619 media processor as possible (completely preserving all the details of the original video streams). This helps to ensure stable playback and prevent playback problems (such as stuttering, hangups, A/V desync) caused by encoding issues in specific files and incompatibilities between these files and Realtek media processor. As the result, Dune HD media players have the most stable Dolby Vision playback among all RTD1619-based media players. It is especially useful when playing not the 100% exact images of Blu-ray discs, but various manually created and remuxed files, which are often created using non-professional tools and often have muxing errors and problems. • Improvement: Fixed various problems with playback of various Dolby Vision files (with the help of the new Dune HD Dolby Vision Purifier engine). • Improvement: HDMI CEC functionality rewrote to fix various problems (it was not working in many cases). HDMI CEC settings extended. Now you can control the media player by TV remote, configure if the media player should be switched on/off when the TV is switched on/off, and configure if the TV should be switched on/off when the player is switched on/off. • Improvement: Built-in HDD format function extended to more properly support huge (12TB+) HDDs. • Improvement: Built-in HDD format function improved to ensure better compatibility of the formatted HDDs with various operating systems. • Improvement: Improved compatibility with NTFS and HFS+ HDDs formatted by various other devices and operating systems. • Improvement: Optimized the read-write performance of NTFS and HFS+ HDDs. • Improvement: Various small improvements and fixes in "HDMI Input" application. • Improvement: After settings reset, the initial setup screen shows a hint describing how to pair the Bluetooth remote. • Max Vision 4K: Small internal optimizations in the handling of Hi-Fi audio output. • Bugfix: Jumping between chapters in Blu-ray menu could work wrongly in some cases. • Bugfix: When playing files with DTS HD MA audio tracks, A/V desync could happen in some cases. • Bugfix: When playing MKV files with ASS/SSA subtitles, playback crash could happen in some cases. • Bugfix: Adjustment of picture brightness/contrast/saturation/hue did not work properly during Dolby Vision playback. • Bugfix: Playback of DASH video streams by the internal player could wrongly handle some errors in the stream in some cases. • SDK: New feature: the dune_param parameter "engine:3" can be used to force the use of Hi-Fi internal audio player. • Minor other fixes and improvements.
• This version adds various Dolby Vision related improvements. • New feature: Dolby Vision decoding and output is now supported also when playing separate M2TS P7 (MEL and FEL) files. NOTE: Dolby Vision extended information from the second video track is used and output to TV, i.e. it is a real playback of Dolby Vision video (as previously already supported for BDMV folders and BD ISO files). • New feature: You can now force Dolby Vision output (in both LLDV and STD DV modes) even if the media player believes that the connected TV does not support Dolby Vision. To do so, just set "Setup / Video / HDR and Dolby Vision settings / Dolby Vision output mode" to "LLDV" or "STD DV" (instead of "Auto"). This feature can also be potentially used instead of EDID-editing function in "HDFury" devices for output of LLDV Dolby Vision to projectors, i.e. it can allow you avoid to need to buy the "HDFury" device. • Bugfix: When outputting Dolby Vision, HDMI disconnect/reconnect or TV on/off could be handled in a wrong way. • Bugfix: When outputting Dolby Vision, screen burn prevention function (screensaver) could be handled in a wrong way. • Bugfix: Dolby Vision output did not work in some cases for some Panasonic TV models (which support both Dolby Vision and HDR10+). • Bugfix: When playing Dolby Vision, playback hangup could happen after some time in some cases. • Bugfix: BD-J program on some Dolby Vision Blu-ray discs (such as "Dolby UHD Blu-Ray Demo Disc") could not properly detect that the player supports Dolby Vision. • Bugfix: Some incorrectly manually converted images of Dolby Vision Blu-ray discs could be played incorrectly. NOTE: To ensure that you get the proper Dolby Vision picture, it is recommended to play the exact (1:1) copies of original discs; manually converted (muxed) disc images may contain muxing errors which may cause Dolby Vision to not work properly. • Minor other fixes and improvements.
• The first firmware version recommended for this model. • In comparison with the initial "r15" firmware version, which was preinstalled at the factory, this version adds the following. • Dolby Vision decoding and output when playing the following types of content: • Blu-ray disc images: • BDMV folder played in Full Menu mode, P7 MEL and FEL. • BDMV folder played in Lite mode, P7 MEL and FEL. • BD ISO played in Full Menu mode, P7 MEL and FEL. • BD ISO played in Lite mode, P7 MEL and FEL. • Files: • MKV P5. • MKV P7 MEL single-track. • MKV P8. • MP4 P5. • MP4 P7 MEL single-track. • M2TS P8. • NOTE: Dolby Vision support for other file variations is planned to be improved in further firmware updates (priorities: M2TS, MKV, MP4). • NOTE: In all these cases, Dolby Vision extended information from the original video stream is used and output to TV, i.e. it is a real playback of Dolby Vision video, and not just a conversion of the HDR10 base layer to Dolby Vision via VS10 engine. • "Setup / Video / HDR and Dolby Vision" menu with the following settings: • "HDR processing mode": • Determines how the media player processes SDR, HDR and Dolby Vision content. • "Auto": choose the preferred output format automatically based on the played content (output SDR for SDR video, HDR for HDR video, DV for DV video). • "HDR always": always output HDR (convert SDR to HDR). • "SDR always": always output SDR (convert HDR/DV to SDR). • "SDR BT.2020 for BT.2020 video": output SDR BT.2020 when playing BT.2020 video. • "HLG always": always output HLG HDR (convert SDR to HDR). • "Dolby VS10 engine always": always use VS10. • "Dolby VS10 engine for video": use VS10 when playing SDR video. • "Dolby VS10 engine for HDR video": use VS10 when playing HDR video. • "Dolby VS10 engine for DV video": use VS10 when playing DV video. • "Dolby VS10 engine for SDR, HDR video": use VS10 when playing SDR or HDR video. • "Dolby VS10 engine for SDR, DV video": use VS10 when playing SDR or DV video. • "Dolby VS10 engine for HDR, DV video": use VS10 when playing HDR or DV video. • "Dolby VS10 engine for SDR, HDR, DV video": use VS10 when playing any video (but not in the main menu). • Default is "Auto". • NOTE: VS10 may be useful even when playing non-DV content and when outputting to non-DV TV, because of the following reasons: • VS10 improves picture quality and minimizes the effect of "posterization" ("banding") due to more advanced 12-bit video processing. • VS10 improves the quality of SDR to HDR and HDR to SDR conversion. • "Dolby Vision output mode": • "Auto": choose LLDV or STD DV automatically based on TV capabilities and preferences. • "LLDV": prefer to use LLDV. (Dolby Vision processing is led by the player.) • "STD DV": prefer to use STD DV. (Dolby Vision processing is led by the TV.) • Default is "Auto". • "Dolby Vision 4Kp50/60": • Choose "Disabled" if your A/V equipment supports DV only up to 4Kp30 (e.g. some old TV models did not support DV 4Kp60). • Default is "Enabled". • Max Vision 4K: Support for Hi-Fi audio output. • Max Vision 4K: OLED display: showing extended information about the currently played file: filename, playback time, graphical timeline. • Max Vision 4K: OLED display: control mode, which makes it possible to use the OLED display to control the player when the TV is switched off. • To enable the control mode: press INFO remote button for 2 seconds. • To disable the control mode: press INFO remote button for 2 seconds again. • In the control mode, the OLED display works as follows: • When no file is played: • Instead of showing the clock, the OLED display shows the browser of the player menu. • You can browse the player menu using remote buttons UP, DOWN, ENTER, RETURN. This way, you can so almost everything you can do via "Dune Control" mobile app, in particular, browse arbitrary folders and files. • When a file is played: • You still see the same extended information about the currently played file, but you additionally can conveniently rewind the playback using LEFT/RIGHT and UP/DOWN buttons of the remote. • The control mode is indicated in the top right corner of th OLED display by "*" character. • Max Vision 4K: OLED display: do not display seconds in clock by default. (If needed, can be enabled in "Setup / Misc / Display".) • Max Vision 4K: OLED display: show AM/PM when 12h clock format is used. • New feature: The fan speed can be adjusted via "Setup / Misc / Power managment / Fan" setting. Default is "Auto". • Improved compatibility with some Blu-ray disc images when using full menu mode. • Bufix: when playing some Blu-ray disc images in full menu mode, subtitles could be wrongly activated by default when not needed. • Bugfix: when playing video files, the initial audio track could be wrongly chosen in some cases. • Minor other fixes and improvements. • NOTE: This firmware is based on a different Realtek 1619 SDK version (not the same as used in "r15" firmware versions, so it may have a different set of issues and limitations in comparison with "r15" firmware versions). • NOTE: In comparison with the previous firmware version 210202_1854_r17, this firmware version fixes the following problems: severe video stuttering and A/V desync occuring in some cases, Dolby Vision not working for BD ISO images in Lite mode, missing Google Play / ATV, total hangup of the player (with the need to do a factory reset via the Recovery menu). • NOTE: If you previouslly installed the 210202_1854_r17 firmware version, it is recommended to do a factory reset ("Setup / General / Reset Settings") before updating to this version, to reduce the risk of encountering "total hangup of the player" problem and the need to do factory reset via the Recovery menu.
The first firmware update provided for Pro Vision 4K Solo and Max Vision 4K models. This version has critical problems, it should not be used. The next version 210214_0333_r17 is recommended instead.
