write_videofile does not add audio

[cristidomsa]

I encounter a problem on Amazon Linux.

I have a code which generates composite videos. On ubuntu 18.04 is working file, on Amazon Linux the audio is not embedded in the video. The temporary audio file contains the proper audio.
I've tried to specify the codecs or not, it's not working.

CODE:

write_videofile(self.v3_name,
                                            write_logfile=True,
                                            threads=8,
                                            preset='ultrafast',
                                            temp_audiofile='temp-audio.mp3',
                                            rewrite_audio=True,
                                            audio=True,
                                            remove_temp=False)

Here are the logs:

I faced this issue as well on a project I'm currently working on and it seems like many people are facing this issue as well. For some people, by changing the audio encoding that did the trick and fixed the issue (such as #820). However, changing the audio encoding didn't work for me, the only solution I found for this issue is one mentioned in #876 was to remove the -an from the ffmpeg_writer.py file in
\site-packages\moviepy-1.0.1-py3.7.egg\moviepy\video\io

After I removed the -an from there it all worked like a charm.

[thenewguy]

Try specifying as audio='temp-audio.mp3' and removing the temp_audiofile option.

See my test here: /~https://github.com/Zulko/moviepy/pull/1037/files#diff-488857f543e242a02c35d5b0b73668eaR208

Please let me know if that fixes your problem. If not, please output the ffmpeg command line generated so I can write a test to cover your case

To get the command logged to your console (until it is merged) you can pip install /~https://github.com/thenewguy/moviepy/archive/log-ffmpeg-command.zip#egg=moviepy

@THConer if possible, please review my test cases. If they do not cover your case, please let me know the difference so I can update them.

hello,the example is working，but how can i subclip the audio clip?

[UAEpro]

I have no audio also. This is the command
Moviepy - Using FFMPEG command:
/home/XXX/anaconda3/envs/snap2/lib/python3.7/site-packages/imageio_ffmpeg/binaries/ffmpeg-linux64-v4.1 -y -loglevel error -f rawvideo -vcodec rawvideo -s 360x712 -pix_fmt rgb24 -r 30.00 -i - -an -vcodec libx264 -preset ultrafast -pix_fmt yuv420p y.72827.mp4

before it was writing the audio and then writing the video, now it's writing the video directly

------------------------------------------- edit ----------------------------------------
i Know this is strange the code was working fine before
the old code was (which suddnly it has no sound)

    with VideoFileClip(os.path.join(dir_name, file),audio=True).rotate(rotateVal) as i:
        clips.append(i)

the new edited code which has sound

    clips.append(VideoFileClip(os.path.join(dir_name, file),audio=True).rotate(rotateVal))

[tburrows13]

Should be fixed in #968. Feel free to reopen if not.

[zhanwenchen]

@tburrows13 It's not fixed:

/~https://github.com/Zulko/moviepy/blob/master/moviepy/video/io/ffmpeg_writer.py#L117

[gorlang]

This applies to moviepy Version: 2.1.1

Problem: No audio in final video after adding a mp3 sound file.

Seems to be a problem in line 123 in ffmpeg_writer.py:

if audiofile is not None:
cmd.extend(["-i", audiofile, "-acodec", "copy"])

Behaviour: -acodec is hard coded to "copy".

That works fine if the input file is m4a-format (mandatory in a mp4 video), but not if the input is mp3 or other, the mp3 file is copied into the video, but there is no sound when played.

Temporary workaround: Replace "copy" with "aac" in the code line 123 and it will work for mp3 audio files.

Cause: The audio_codec param passed in VideoClip.write_videofile() isn't used down the pipeline in ffmpeg_writer.py so there's no way to change the codec, which is needed if the input audio isn't m4a.

Hope that helps!
