AWS Lambda Docker image with librosa and ffmpeg
4 août 2022, par loretoparisiI'm using this
Dockerfileto build an image for AWS Lambda havinglibrosaandffmpegwithpython3.7:

ARG FUNCTION_DIR="/function"
FROM python:3.7.4-slim-buster as build-image

# librosa and ffmpeg dependencies
RUN apt-get update && apt-get install -y \
 software-properties-common \
 libsndfile1-dev \
 ffmpeg

# Install aws-lambda-cpp build dependencies
RUN apt-get update && \
 apt-get install -y \
 g++ \
 make \
 cmake \
 unzip \
 libcurl4-openssl-dev

# Include global arg in this stage of the build
ARG FUNCTION_DIR
# Create function directory
RUN mkdir -p ${FUNCTION_DIR}

# Copy function code
COPY app.py ${FUNCTION_DIR}

# Install the runtime interface client
RUN pip install \
 --target ${FUNCTION_DIR} \
 awslambdaric

# Multi-stage build: grab a fresh copy of the base image
FROM python:3.7.4-slim-buster

# Include global arg in this stage of the build
ARG FUNCTION_DIR
# Set working directory to function root directory
WORKDIR ${FUNCTION_DIR}

# Copy in the build image dependencies
COPY --from=build-image ${FUNCTION_DIR} ${FUNCTION_DIR}

EXPOSE 8080
ENTRYPOINT [ "/usr/local/bin/python", "-m", "awslambdaric" ]
CMD [ "app.handler" ]


The build works ok, but I cannot run the image :


docker run -e AWS_LAMBDA_RUNTIME_API=localhost:9000 --rm -it -p 9000:8080 lambda:latest
Executing 'app.handler' in function directory '/function'
[ERROR] [1628271126733] LAMBDA_RUNTIME Failed to get next invocation. No Response from endpoint
Traceback (most recent call last):

 File "/function/awslambdaric/bootstrap.py", line 399, in run
 event_request = lambda_runtime_client.wait_next_invocation()
 File "/function/awslambdaric/lambda_runtime_client.py", line 76, in wait_next_invocation
 response_body, headers = runtime_client.next()
RuntimeError: Failed to get next
</module>

I therefore tried this simplified
Dockerfilethat is based on the AWS EC2 CentOS with package manageryum:

FROM public.ecr.aws/lambda/python:3.8

# libsndfile
RUN curl -o libsndfile-1.0.28-alt1.x86_64.rpm http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic//libsndfile-1.0.28-alt1.x86_64.rpm 
RUN curl -o libsndfile-devel-1.0.28-alt1.x86_64.rpm http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic//libsndfile-devel-1.0.28-alt1.x86_64.rpm
#ffmpeg
RUN curl -o ffmpeg-4.4-alt5.x86_64.rpm http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic//ffmpeg-4.4-alt5.x86_64.rpm 

RUN yum localinstall \
 libsndfile-devel-1.0.28-alt1.x86_64.rpm \
 fmpeg-4.4-alt5.x86_64.rpm

# Create function directory
WORKDIR /app

# Copy function code
COPY app.py .

COPY requirements.txt .
RUN pip install -r requirements.txt

EXPOSE 8080
# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD ["/app/app.handler"]


In this case, the image builds and run and I can invoke the handler :


docker run --rm -it -p 9000:8080 lambda:latest
INFO[0000] exec '/var/runtime/bootstrap' (cwd=/app, handler=) 
curl -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{}'


but I
librosacomplains about thelibsndfile1installation :

During handling of the above exception, another exception occurred:

The strange thing in this case (
yumandrmp) is that the installation seems to work fine :

Playing a music on speaker,record it with ffmpeg and save as
music.mp3in current directory.

device_speaker="alsa_output.pci-0000_09_00.6.analog-stereo.monitor"
ffmpeg -f pulse -i $device_speaker music.mp3


I turn off the speaker and play the music on my headphone,how can record it with ffmpeg ?

cannot hear audio after saving RTSP stream as ts or avi or mp4 files using ffmpeg command
28 mai 2022, par ewangI am still new to ffmpeg and trying to save RTSP stream from the IP camera (Meraki MV2) via RTSP link (rtsp ://192.168.0.80:9000/live) to local laptop (Windows 10) as ts file, or avi or mp4 files, but none of them can hear sound. In Meraki MV2 camera dashboard audio is enabled
meraki dashboard audio enabled screenshot


And below is the ffmpeg command i used :


ffmpeg -use_wallclock_as_timestamps 1 -rtsp_transport tcp -i rtsp://192.168.0.80:9000/live -f mpegts -b 400k -r 25 -vcodec libx264 -s 640x480 -aspect 4:3 -bufsize 6000k -acodec aac -ab 56k -ac 2 -ar 22050 -bf 0 -level 30 -y record_a_v.ts


In below part of the result log, noticed Steam mapping has a #0:1 -> #0:0 and #0:0 -> #0:1, is it supposed to be crossed or not really ?
