Problems with Python's azure.cognitiveservices.speech when installing together with FFmpeg in a Linux web app
15 mai 2024, par Kakobo kakoboI need some help.
I'm building an web app that takes any audio format, converts into a .wav file and then passes it to 'azure.cognitiveservices.speech' for transcription.I'm building the web app via a container Dockerfile as I need to install ffmpeg to be able to convert non ".wav" audio files to ".wav" (as azure speech services only process wav files). For some odd reason, the 'speechsdk' class of 'azure.cognitiveservices.speech' fails to work when I install ffmpeg in the web app. The class works perfectly fine when I install it without ffpmeg or when i build and run the container in my machine.


I have placed debug print statements in the code. I can see the class initiating, for some reason it does not buffer in the same when when running it locally in my machine. The routine simply stops without any reason.


Has anybody experienced a similar issue with azure.cognitiveservices.speech conflicting with ffmpeg ?


Here's my Dockerfile :


# Use an official Python runtime as a parent imageFROM python:3.11-slim

#Version RunRUN echo "Version Run 1..."

Install ffmpeg

RUN apt-get update && apt-get install -y ffmpeg && # Ensure ffmpeg is executablechmod a+rx /usr/bin/ffmpeg && # Clean up the apt cache by removing /var/lib/apt/lists saves spaceapt-get clean && rm -rf /var/lib/apt/lists/*

//Set the working directory in the container

WORKDIR /app

//Copy the current directory contents into the container at /app

COPY . /app

//Install any needed packages specified in requirements.txt

RUN pip install --no-cache-dir -r requirements.txt

//Make port 80 available to the world outside this container

EXPOSE 8000

//Define environment variable

ENV NAME World

//Run main.py when the container launches

CMD ["streamlit", "run", "main.py", "--server.port", "8000", "--server.address", "0.0.0.0"]`and here's my python code:



def transcribe_audio_continuous_old(temp_dir, audio_file, language):
 speech_key = azure_speech_key
 service_region = azure_speech_region

 time.sleep(5)
 print(f"DEBUG TIME BEFORE speechconfig")

 ran = generate_random_string(length=5)
 temp_file = f"transcript_key_{ran}.txt"
 output_text_file = os.path.join(temp_dir, temp_file)
 speech_recognition_language = set_language_to_speech_code(language)
 
 speech_config = speechsdk.SpeechConfig(subscription=speech_key, region=service_region)
 speech_config.speech_recognition_language = speech_recognition_language
 audio_input = speechsdk.AudioConfig(filename=os.path.join(temp_dir, audio_file))
 
 speech_recognizer = speechsdk.SpeechRecognizer(speech_config=speech_config, audio_config=audio_input, language=speech_recognition_language)
 done = False
 transcript_contents = ""

 time.sleep(5)
 print(f"DEBUG TIME AFTER speechconfig")
 print(f"DEBUG FIle about to be passed {audio_file}")

 try:
 with open(output_text_file, "w", encoding=encoding) as file:
 def recognized_callback(evt):
 print("Start continuous recognition callback.")
 print(f"Recognized: {evt.result.text}")
 file.write(evt.result.text + "\n")
 nonlocal transcript_contents
 transcript_contents += evt.result.text + "\n"

 def stop_cb(evt):
 print("Stopping continuous recognition callback.")
 print(f"Event type: {evt}")
 speech_recognizer.stop_continuous_recognition()
 nonlocal done
 done = True
 
 def canceled_cb(evt):
 print(f"Recognition canceled: {evt.reason}")
 if evt.reason == speechsdk.CancellationReason.Error:
 print(f"Cancellation error: {evt.error_details}")
 nonlocal done
 done = True

 speech_recognizer.recognized.connect(recognized_callback)
 speech_recognizer.session_stopped.connect(stop_cb)
 speech_recognizer.canceled.connect(canceled_cb)

 speech_recognizer.start_continuous_recognition()
 while not done:
 time.sleep(1)
 print("DEBUG LOOPING TRANSCRIPT")

 except Exception as e:
 print(f"An error occurred: {e}")

 print("DEBUG DONE TRANSCRIPT")

 return temp_file, transcript_contents



The transcript this callback works fine locally, or when installed without ffmpeg in the linux web app. Not sure why it conflicts with ffmpeg when installed via container dockerfile. The code section that fails can me found on note #NOTE DEBUG"

ffmpeg concatenation with -filter_complex
16 octobre 2018, par IgniterI’ve seen several similar questions but none of them actually helped in my case.
Getting this error while trying to join 1 audio and 4 video files of different nature and resolutions.ffmpeg -i 0.mp3 -i 1.mp4 -i 2.mkv -i 3.mkv -i 4.webm \
-filter_complex [0:a:0][1:v:0][2:v:0][3:v:0][4:v:0]concat=n=5:v=1:a=1[outv][outa] \
-map "[outv]" -map "[outa]" output.mp4All this gives the following error :
Stream specifier ':a:0' in filtergraph description [0:a:0][1:v:0][2:v:0][3:v:0][4:v:0]concat=n=5:v=1:a=1[outv][outa] matches no streams.
Straight concatenation
-i "concat:0.mp3|1.mp4..."
also doesn’t work as expected due to different resolutions and video formats. All methods syntax was taken from official documentation but there should be something that I’ve missed here.Full output log :

Trouble with CoCCA Registry
7 octobre 2012, par Multimedia Mike — GeneralI’ve been rather despondent all week. People who see me daily could readily identify this fact. Unfortunately, the exact reason was difficult to adequately explain. The problems that nerds deal with…
When A Domain Expires
As a few people noticed, the multimedia.cx domain and all of it’s subdomains didn’t work this last week. The problem started on Monday, October 1. Whose fault ? Well, fundamentally, I neglected to renew the domain name in time. However, I prefer to place the blame on the .cx domain registrar, CoCCA Registry. You see, they have never developed the technology to email a domain holder with a notice that their domain is about to expire or has already expired.This domain is the only one I have ever held so I don’t have a lot of experience in this matter. I wondered if I was crazy for thinking it would be normal for a registrar to send an email or 2 with status updates about your domain. I get the impression from speaking with others that this is indeed normal. I have 3 different email addresses listed under my account at the registrar– 2 at multimedia.cx and a backup gmail account. I checked spam folders after this incident. Then I remembered that I have never received any email notifications from them (although password reset emails show up, so that part thankfully works). Also, their support emails are black holes.
So, I guess the moral is : be wary of dealing with CoCCA Registry. However, they seem to be the only way to register domains under a wide variety of uncommon country codes.
By Friday, the domain appeared to have been reinstated, even through the status was officially listed as “renewal-pending” according to the web-based management console. Eventually, as cached DNS results started to time out throughout the day, I started seeing subdomains come back. I excitedly used the ‘dig’ command to count down the seconds until gamemusic.multimedia.cx was accessible on the network I was on (the number after the domain name is the time-to-live or ‘TTL’ value) :
$ dig +nocmd gamemusic.multimedia.cx +noall +answer gamemusic.multimedia.cx. 3 IN A 174.143.152.251 $ dig +nocmd gamemusic.multimedia.cx +noall +answer gamemusic.multimedia.cx. 2 IN A 174.143.152.251 $ dig +nocmd gamemusic.multimedia.cx +noall +answer gamemusic.multimedia.cx. 1 IN A 174.143.152.251 $ dig +nocmd gamemusic.multimedia.cx +noall +answer gamemusic.multimedia.cx. 12962 IN A 207.45.186.114
Finally, today (Saturday), I received a receipt confirming that the domain has been renewed.
8 Years Old
Incidentally, happy eighth birthday to multimedia.cx. It was September, 2004 when I decided to branch out from a simple ISP-based web presence.People often ask why I went with the .cx TLD. When I decided I wanted a proper domain name 8 years ago, I found that multimedia.X was already taken for just about every TLD value of X. .cx was a notable exception and was distinctive enough (speaking of .X, though, I see that multimedia.xxx is still up for grabs as of this writing ; I imagine that would come with a whole other set of problems).
It’s funny that tech nerds often rail against outsourcing too much — email, storage, computing power, web hosting — all to some type of cloud provider under the premise that it could easily be taken away. But this episode teaches me that even having your own domain name is no guarantee of a solid online presence.
Meanwhile, I have taken proactive steps to avert this same situation from arising again :
Barring a lack of automated emails from the registrar, I hope a Google Calendar reminder set up a month ahead of expiration will do the trick.
