Giới thiệu về chuyển đổi ALAC sang FLV
ALAC stores lossless audio in Apple's M4A container. FLV (Flash Video) is Adobe's legacy streaming container, supporting MP3 and AAC audio. Flash Player reached end-of-life in December 2020.
Converting ALAC to FLV leverages lossless source quality for optimal Flash format output. Since ALAC decodes to perfect PCM, the AAC/MP3 encoding in FLV benefits from the best possible source material.
Tại sao nên chuyển đổi ALAC sang FLV?
Legacy RTMP streaming servers and Flash-based platforms require FLV input. Converting ALAC to FLV enables lossless Apple recordings to enter Flash streaming pipelines.
The lossless ALAC source ensures the best possible AAC or MP3 quality within FLV — a single lossy step from perfect PCM.

Cách hoạt động
FFmpeg decodes ALAC to perfect PCM and encodes to AAC or MP3 within FLV. The lossless decode means only one lossy step — producing optimal FLV audio quality. FLV metadata is stored in the onMetaData script tag.
Chất lượng & hiệu suất
AAC at 128-256 kbps from ALAC produces excellent quality — single-generation lossy encode from perfect source. Better than converting from any other lossy format.
