运行前提：

proposed；不是上游逐字完整示例；本机所需输入解码器、pcm_s16le编码器与WAV muxer均待检查。
只使用授权音频与新输出路径；旧投稿Linux测试不作为本profile实测。

使用步骤：

先核对本机构建支持输入解码、pcm_s16le与WAV输出；未具备则不执行。
参数组合候选：ffmpeg -n -i INPUT -map 0:a:0 -vn -ac 1 -ar 16000 -c:a pcm_s16le OUTPUT.wav
待执行后检查输出编码、采样率16000、单声道、时长/音频可听与源对应。

输入约定: 单个授权且构建可解码的含音轨媒体；不承诺所有输入格式。
输出约定: 候选单声道16kHz、16位PCM WAV；本页没有pcm_s16le字面证明，输出与编码支持均未实测。
成功检查: 待适配：检查流属性和解码播放、时长/截断/削波；不把预处理当语音识别效果。
失败与回退: 无音轨/编码器/muxer或解码失败则停止，保留原始文件与错误，不下载执行未知代码。

ffmpeg [global_options] {[input_file_options] -i input_url} ... {[output_file_options] output_url} ... 2 Description# TOC ffmpeg is a universal media converter. It can read a wide variety of inputs - including live grabbing/recording devices - filter, and transcode them into a plethora of output formats. ffmpeg reads from an arbitrary number of inputs (which can be regular files, pipes, network streams, grabbing devices, etc.), specified by the -i option, and writes to an arbitrary number of outputs, which are specified by a plain output url. Anything found on the command line which cannot be interpreted as an option is considered to be an output url.

-ar[:stream_specifier] freq (input/output,per-stream) Set the audio sampling frequency. For output streams it is set by default to the frequency of the corresponding input stream. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. -aq q (output) Set the audio quality (codec-specific, VBR). This is an alias for -q:a. -ac[:stream_specifier] channels (input/output,per-stream) Set the number of audio channels. For output streams it is set by default to the number of input audio channels. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options.

运行前提：

Existing authorized installation with exact binary SHA
Input is actual JPEG1200x800/RGB with SHA e2923b1662fdf1b3c577d19f4a6b1ee57f6b41a6f4b45c44b2ebc9e3d2e8b97c
Partial query gaps about cost/region/retention do not become verified; no installation or upload

使用步骤：

Read actual byte signature and input SHA; preserve original
ffmpeg -nostdin -hide_banner -loglevel error -n -protocol_whitelist file -i INPUT -vf scale=945:630:flags=lanczos,format=rgb24,pad=1200:630:127:0:white,setsar=1 -frames:v 1 -c:v png -compression_level 9 -threads 1 OUTPUT
Decode actual output fully, check1200x630, media,307200B/756000pixel cap, full-frame/padding/no-upscale; on failure retain evidence and stop

输入约定: Exact owned source e2923b1662fdf1b3c577d19f4a6b1ee57f6b41a6f4b45c44b2ebc9e3d2e8b97c; source99659B JPEG even though png filename; no general input substitution
输出约定: png1200x630 contain white; 578285B observed; exceeds307200B. No broader size guarantee.
成功检查: Pillow full decode/pixel access and FFprobe; compare whole source and padding. Exit0 alone is insufficient. No ICC/EXIF/alpha generalization.
失败与回退: Return unknown/conflict, keep original and failure. PNG budget conflict must not be retried automatically or constraints weakened.

命令退出码为0
输出可被独立Python wave解析
44.1kHz双声道输入转换为16kHz单声道
输出为16位PCM，时长保持1秒

未验证范围

未验证语音识别或准确率提升
未验证全部格式与编解码器
未验证降噪和主观听感

这是有条件的提交者观察。HTTP、安装、执行、输出核对和用户验收分别判断；不计算总体成功率或商业收入。
