Description:
MintVID is a multi-codec video player for accelerated 68k Amigas, from
68030-class ECS/AGA systems through 68040/060 machines to PiStorm/Emu68.
It supports native chipset and RTG output, local files, HTTP/HTTPS, HLS,
IPTV and public YouTube playback.
WHAT'S NEW IN 1.1.1
- Adds native WMV1 / Windows Media Video 7 decoding for AVI files.
- Adds native WMV2 / Windows Media Video 8 decoding for AVI files, including
MSPEL, adaptive block transforms and in-loop deblocking used by normal
WMV2 I/P streams.
- WMV1 and WMV2 are regression-tested against ffmpeg on the host and on a
big-endian m68k target under QEMU.
- Fixes the remaining live-HLS ESC/Stop shutdown regression seen as a
"MintVID HLS fetch" #80000004 worker failure on A1200/WinUAE testing.
HLS now uses the proven 1.0.0 single-next-segment compressed lookahead
policy while keeping the 1.1.0 hard worker join and AmiSSL lifecycle fixes.
- The shared About requester now describes the wider local/streaming codec
support and calls out WMV7/WMV8 alongside MPEG and H.264 playback.
MintVID 1.1.1 is a small stability/codec follow-up to 1.1.0. The TurboGT,
Kalms C2P, RTG direct-write, YouTube, RAM-aware queueing and other 1.1.0
improvements remain present.
See CHANGELOG.txt in the release archive, or CHANGELOG.md in the source tree,
for the detailed list.
Codec support does not imply real-time playback on every CPU. Practical
performance depends on processor speed, codec complexity, resolution,
bitrate and display mode. Lightweight older codecs are the natural fit
for classic accelerators; modern H.264 streaming is primarily aimed at
PiStorm/Emu68-class systems.
WHO THIS IS FOR
MintVID is aimed at accelerated Amiga hardware whose owner wants a broad
video player with local-file, network, YouTube and IPTV support. On classic
68030/040/060 accelerators, the supported online formats should not be read as
a promise of smooth H.264 streaming; those features are also useful for
compatibility testing and experimentation. PiStorm/Emu68-class systems are
the main target for practical H.264 YouTube/IPTV use.
MintVID uses the same feature set across its 68030, 68040 and 68060 builds.
There is no separate AGA, RTG or PiStorm feature edition; display mode and
practical playback performance depend on the hardware underneath it.
- 68030-class ECS/AGA systems - best suited to lightweight codecs and
modest frame sizes. Cinepak is the natural starting point; heavier
formats may decode correctly without being practical in real time.
- 68040/060 systems - older codecs such as Cinepak, MJPEG, MPEG-1/2,
MPEG-4 Part 2 and WMV7/8 become more practical at modest resolutions,
especially with RTG. H.264/AVC remains far too demanding for normal
real-time YouTube/IPTV viewing on classic CPUs. On a tested 68060 using
AGA, lowest-resolution YouTube/IPTV H.264 playback has been around 7 fps
at best. Treat H.264 streaming on classic 040/060 hardware as a
compatibility or demonstration path rather than smooth video playback.
- PiStorm/Emu68 - use the MintVID040 build. This is the build targeted for
the Emu68/PiStorm environment. H.264/AVC (Baseline through High Profile,
CABAC and B-frames) becomes much more practical here. On the tested
Pi3-based PiStorm 600, low-resolution H.264 streams below roughly 200p
have played well. Faster PiStorm hardware should provide more headroom,
but exact results depend on the stream and configuration.
- Vampire/Apollo 68080 - not yet validated by the MintVID project, so no
optimised build is officially recommended yet. Do not assume the 68060
build is the correct choice solely from the CPU name; feedback from real
Vampire hardware is welcome.
WHAT IT PLAYS
- Containers: AVI, QuickTime MOV/MP4, Matroska/MKV, MPEG-TS/M2TS, raw
MPEG-1 program streams, raw MJPEG/MPEG-4 Visual streams, and direct
HTTP(S)/HLS URLs (including live IPTV playlists and YouTube).
- Video codecs: Cinepak, Microsoft Video 1, Microsoft RLE8, uncompressed
UYVY422, H.263 baseline, Motion-JPEG, MPEG-1, MPEG-2 (with B-frames),
MPEG-4 Part 2 (ISO ASP and Microsoft MP42/DIV2), Windows Media Video 7
(WMV1), Windows Media Video 8 (WMV2), and H.264/AVC Baseline/Main/High
Profile.
- Audio to Paula: PCM, MP2, MP3, AAC-LC (raw/ADTS/LATM), and fixed-point
AC-3 (stereo downmix). MP3/AAC decoding reuses the proven MintAMP/Helix
code.
- Two complete GUI sets over the same player: ReAction (V44) and plain
GadTools/Intuition (V37) for a standard AmigaOS 3.0 install, each with
matching file, IPTV-directory and YouTube-search browser windows.
WMV compatibility notes: WMV1's low-bitrate spatial intra/inter prediction
mode is not implemented and is rejected rather than approximated. WMV2's
IntraX8 (J-frame) mode is likewise not supported. Normal tested WMV1/WMV2
AVI I/P streams use the native decoders.
MintVID's core decoders are regression-tested against ffmpeg using the
project's test fixtures where applicable. The portable core is also
cross-built and exercised on a big-endian m68k target under QEMU to catch
endianness and alignment problems that a little-endian x86 host build can
miss - see the project page for details.
DEFAULTS AND H.264 SPEED MODES
Kalms is the default C2P choice for AGA/HAM playback. If the selected geometry
or BitMap layout cannot use its CPU-matched converter, MintVID automatically
falls back to the established graphics.library path. RTG ignores C2P choices.
TurboGT is the default H.264 mode. Auto currently selects the same policy.
- Quality: full filtering, no deliberate frame skipping.
- Balanced: reduces work only on non-reference pictures; often close to
Quality on streams with few B-frames.
- Fast: cheaper filtering on non-key pictures, but keeps every frame.
- Turbo: Fast policy plus B-frame skipping; preserves the P-frame chain.
- Turbo+: skips both P- and B-frames. This is a last-resort keyframe/
slideshow mode, not the normal fastest setting.
- TurboGT: skips B-frames, retains P-frames, and applies maximum degradation
to every decoded picture. It is the recommended aggressive PiStorm/Emu68
setting and the default from the 1.1.x line.
WHAT IT IS NOT
MintVID uses a modular decoder architecture, so its supported format list can
grow without tying the player to one fixed codec. It is not a video editor or
encoder: use ffmpeg or similar on a modern machine to prepare source material,
then play the result on the Amiga. Timeline seeking (cursor left/right,
10 seconds at a time, landing on the nearest keyframe) works for local
QuickTime MOV/MP4 files; AVI, MKV, and network/live sources don't have a
keyframe index yet, so cursor-right stays a fast-forward toggle there instead.
Cursor up/down adjust Paula's volume, and once playback starts, the
controller's Info: field - and, on RTG (CGX/P96), the video window's own title
bar - mirrors a live H:MM:SS/M:SS playhead so you can see where a seek actually
landed.
INSTALLATION
Choose the MintVID030, MintVID040 or MintVID060 drawer for a normal 68030,
68040 or 68060 system respectively. PiStorm/Emu68 users should use
MintVID040. Vampire/Apollo 68080 has not yet been validated, so there is no
official optimised-build recommendation for it yet. Copy the chosen drawer to
your Amiga and keep its contents together.
Run MintVID on systems with ReAction V44, or MintVID-GT for the plain
GadTools/Intuition interface used by a standard AmigaOS 3.0 installation.
IPTV and YouTube browsing are reachable from the controller's menus.
Everything else in the drawer (mrplay, iptvgui, ytgui, the GadTools -GT set,
mr_decode) is a support binary loaded on demand. Nothing in the release drawer
is intended to be split up or copied out on its own.
