问题描述
下面的代码是我用来请求转录的。
import io
from google.cloud import speech_v1p1beta1 as speech
def transcribe_file(speech_file):
"""Transcribe the given audio file."""
client = speech.SpeechClient()
encoding = speech.RecognitionConfig.AudioEncoding.FLAC
if os.path.splitext(speech_file)[1] == ".wav":
encoding = speech.RecognitionConfig.AudioEncoding.LINEAR16
with io.open(speech_file,"rb") as audio_file:
content = audio_file.read()
audio = speech.RecognitionAudio(content=content)
config = speech.RecognitionConfig(
encoding=speech.RecognitionConfig.AudioEncoding.FLAC,sample_rate_hertz=32000,language_code="ja-JP",max_alternatives=3,enable_word_time_offsets=True,enable_automatic_punctuation=True,enable_word_confidence=True,)
response = client.recognize(config=config,audio=audio)
#print(speech_file,"Recognition Done")
return response
正如我在标题中所写的，响应的结果对于某些文件有空列表，而对于某些文件则没有。 它们具有相同的采样率和编解码器（32000，FLAC）
以下是每种情况之一的 ffprobe -i "AUdioFILE" -show_streams 结果。
如何获得非空结果？
编辑：
Result of ffprobe show stream show format
Something not captured in one screen
遗憾的是，re-mux 不起作用。
我使用了 ffmpeg-git-20210225
ffbrobe 损坏的结果
./ffprobe -show_streams -show_format broken.flac
