EVO Player v0.2.0

Subtitles, and the interface for choosing them.

New

• Subtitle track picker. DOWN during playback lists every track in the
  file with the number of cues it declares, the active one marked, and the
  film still playing behind it. It replaces cycling, which reopened the file
  on every step - on a disc rip with thirty-four tracks that meant thirty-odd
  reopens to reach the one you wanted.
• Track names are built from the language code, not the container's title.
  The font atlas has no accents or parentheses, so a track really titled
  Español (España) would draw as a row of holes; fifty language codes map
  to ASCII names, and same-language tracks are numbered rather than shown as
  duplicate rows.

Fixed

• Subtitles appeared to be broken and were not. A release group ships a
  vanity track tagged English, flagged default, holding two cues whose first
  lands thirty-seven minutes in. Selection picked it on metadata alone and
  then correctly displayed nothing for a whole episode. mkvmerge records
  NUMBER_OF_FRAMES per track, so the cue count is readable before a packet
  is demuxed, and it now outranks every other signal: a track with fewer than
  ten cues loses even when it is English and flagged default. Tracks that
  lose this way are still offered in the picker, dimmed and marked
  SIGNS ONLY, because the count can itself be wrong.
• The marquee scrolled at whatever speed the render loop happened to be
  running. It advanced a fixed number of pixels per frame, and the loop
  runs anywhere from 36fps with a preview decoding to 60fps on a settled
  list, so one filename scrolled at two visibly different rates. It measures
  milliseconds now and travels 180px/s regardless.
• The marquee also stepped a glyph at a time, because the offset was
  computed in pixels and then applied by dropping whole characters. The
  sub-character remainder is applied as a negative x, with the glyph
  overhanging each end clipped by keeping and restoring the strips either
  side. Checked on the host: no ink outside the box across 376 phases,
  largest step 3px against a 17px advance.
• EXTRA_CFLAGS never reached the compiler when building from Windows.
  The re-exec into the dev container forwarded PS5_HOST and PS5_PORT and
  dropped everything else, so a -D switch produced a successful build, a
  clean install, and a binary without it. Forwarded now, and the build greps
  its own compile line and fails if a requested flag did not land.

Known gaps

• Cue counts come from mkvmerge's statistics tags. Containers written by
  other tools do not carry them; those tracks are ranked on metadata as
  before and show no count in the picker.
• Switching tracks reopens the file and seeks back, so it costs the same
  pause as a seek. Cues are collected as packets stream past, so a track
  selected mid-film has no cues from earlier in it.

Install

1. Jailbreak the console (12.70) and start ps5-payload-elfldr.
2. Deploy ps5-payload-websrv.
3. Extract the homebrew zip to a USB stick as /homebrew/EVOPlayer/,
   or copy it to /data/homebrew/EVOPlayer/ over FTP.
4. Launch it from http://<ps5>:8080/index.html.

EVOPlayer-*.elf is the bare payload. Note that sending it with
elfldr alone runs it headless — it needs the homebrew launcher to
get a display plane. See the README.

Requirements

• PS5 on firmware 12.70, jailbroken (re-run after every reboot)
• A USB stick for media

Verification

Built reproducibly in CI from the pinned toolchain (clang 18.1.3,
PS5 Payload SDK v0.42, FFmpeg 7.0.1). CI has no console, so these
binaries are not hardware-tested. Checksums in SHA256SUMS.txt.
