Detailed Description

RAII owner of one audio stream's codec and resampler state.

Encapsulates all audio-stream-specific FFmpeg objects:

AVCodecContext for the selected audio stream
SwrContext for sample-format conversion and optional resampling
Cached audio parameters: sample_rate, channel count, total_frames

Does NOT own AVFormatContext — that belongs to FFmpegDemuxContext. Packet reading is always delegated to the demuxer's format_context; this context only decodes and converts packets it receives.

Destruction order (enforced in destructor): swr_context → codec_context The associated FFmpegDemuxContext must outlive this object.
