Avidemux Waveform + Markers 2.8.2

Community release of Avidemux 2.8.2 focused on fast copy-mode editing with visible cached audio waveforms and imported timeline markers.

Added

• Progressive background audio waveform generation.
• Combined/master, separate-track and separate-channel waveform views.
• Waveform seeking with playhead and A/B selection overlay.
• Cached waveform peaks and multi-track background indexing.
• Premiere / XMEML XML, CSV and JSON timeline marker import.
• Imported marker lines and labels on the seek bar and waveform.
• Previous / next imported marker controls with Alt+Left / Alt+Right.

Fixed and validated

• Fixed a Windows waveform-worker GUI deadlock caused by progress UI from a background demuxer.
• Fixed imported-marker navigation when marker timestamps don't match an exact decoded frame PTS.
• 29.97 fps marker regression passed at 15 / 45 / 75 / 105 / 150 seconds in both directions with no seek-error modal.
• Windows portable dependency scan and multi-track smoke launch passed.
• macOS packaging now targets macOS 14+ on Apple Silicon.
• macOS bundle passes strict deep code-signature verification and DMG checksum verification.
• The final macOS DMG is smoke-tested by mounting it and launching the packaged app through macOS LaunchServices, matching Finder-style launch behavior.
