Codename One Adds Video Encoding, PCM Mixing, and Auto-Caption APIs

Codename One, the open-source cross-platform Java/Kotlin app framework, has released three new APIs that together enable apps to build and export media files programmatically. The VideoIO subsystem (PR #5315) allows developers to encode app-rendered frames and audio into standard video files and decode existing clips back into raw RGBA frames and PCM audio. A companion AudioMixer (PR #5317) provides sample-accurate mixing of multiple float PCM tracks on a single timeline, with output compatible with both WAV files and video writers. The updated Whisper transcription API (PR #5319) now returns timed text segments and can export subtitle files in SRT and VTT formats automatically. These additions are supported across iOS, Android, desktop, and web targets, with TV, Watch, and Car platforms excluded from VideoIO support.
