ffplayout v2.2.1

This maintenance release improves playout synchronization and FFmpeg log handling.

Fixed

• Fixed excessive Matroska recording warnings caused by source files with audio and video tracks of significantly different lengths.
• Missing audio is now padded with silence while video continues, instead of being appended in bulk at the end of the file.
• When video ends before audio, the last video frame is repeated to keep both streams synchronized.
• Audio-only sources now receive interleaved black video frames.
• Final timeline alignment remains in place to correct small A/V duration differences and preserve continuous timestamps across playlist items.
• Added tolerance for codec priming and partial final audio frames.

Improved

• FFmpeg log deduplication now detects repeating messages within a six-line window, including alternating patterns such as A, B, A, B.
• Added dedicated fingerprints for recurring Matroska warnings whose memory addresses or negative PTS values change between messages.
• Repeated FFmpeg messages are summarized periodically instead of filling the log file.
• Deduplication remains limited to FFmpeg output and does not affect regular application logs.

Tests

• Added coverage for short audio and video tracks, audio-only media, interleaved padding, alternating log messages, deduplication window limits, and Matroska warning fingerprints.
