英文:
MoviePY error when running in Docker Container using Amazon Elastic Container Service
问题
I'm developing a script that generates a video with the information provided by the user using Moviepy. The application runs in a docker container.
In my test environment (locally) the application usually runs generating the videos as expected. However, when I deploy to the Amazon Elastic Container Instance environment, the application renders the following error:
/tmp/334.mp31boi_q7b: Invalid data found when processing inputHere are the file infos returned by ffmpeg:ffmpeg version 4.2.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2019 the FFmpeg developersbuilt with gcc 8 (Debian 8.3.0-6)libpostproc 55. 5.100 / 55. 5.100libswresample 3. 5.100 / 3. 5.100libswscale 5. 5.100 / 5. 5.100libavfilter 7. 57.100 / 7. 57.100libavdevice 58. 8.100 / 58. 8.100libavformat 58. 29.100 / 58. 29.100libavcodec 58. 54.100 / 58. 54.100libavutil 56. 31.100 / 56. 31.100configuration:--enable-gpl--enable-version3--enable-static--disable-debug--disable-ffplay--disable-indev=sndio--disable-outdev=sndio--cc=gcc--enable-fontconfig--enable-frei0r--enable-gnutls--enable-gmp--enable-libgme--enable-gray--enable-libaom--enable-libfribidi--enable-libass--enable-libvmaf--enable-libfreetype--enable-libmp3lame--enable-libopencore-amrnb--enable-libopencore-amrwb--enable-libopenjpeg--enable-librubberband--enable-libsoxr--enable-libspeex--enable-libsrt--enable-libvorbis--enable-libopus--enable-libtheora--enable-libvidstab--enable-libvo-amrwbenc--enable-libvpx--enable-libwebp--enable-libx264--enable-libx265--enable-libxml2--enable-libdav1d--enable-libxvid--enable-libzvbi--enable-libzimgOSError: MoviePy error: failed to read the duration of file /tmp/334.mp31boi_q7b.
To retrieve files sent by the user, I use tempfile.NamedTemporaryFile and manipulate them in memory. I make some slices in the audio to synchronize with images (as if they were slides) and to concatenate them I use the following:
audio_concat = concatenate_audioclips(audio_clips)
and at the end, I generate the video as follows:
with tempfile.NamedTemporaryFile(prefix=video_path, suffix='', delete=False) as data:video.write_videofile(data.name, fps=24, codec="libx264", ffmpeg_params=['-f', 'mp4'], threads=multiprocessing.cpu_count())
As said, everything works fine in the container locally, but the same does not happen in ECS.
Does anyone have any idea what I might be doing wrong?

在经过大量代码调试后，我已经找到了问题所在。我使用了一个异步服务来生成用于视频的音频。偶尔，音频生成过程会变得更长，由于我的疏忽，在使用音频之前未能进行验证。
因此，在我的情况下，会出现错误 OSError: MoviePy error: failed to read the duration of file /tmp/334.mp31boi_q7b. ，这是因为音频文件为空。就是这样！
在本地运行音频时，生成过程中的延迟非常小，这就是为什么本地没有出现问题的原因。

after extensive code debugging, I have identified the issue. I utilize an asynchronous service that generates audio to be used in the video. Occasionally, the audio generation process took longer, and due to my oversight, I failed to verify before utilizing the audio.
Therefore, the error OSError: MoviePy error: failed to read the duration of file /tmp/334.mp31boi_q7b. occurs (in my case) because the audio file was empty. That's it!
When running the audio locally, the latency in the generation process was minimal, which is why no issues occurred locally.
