• ffmpeg remote url not working in lambda function

  9 septembre 2024, par Komal

  I have created lambda function to trim video.

  


  I run this command :

  


  /opt/bin/ffmpeg -protocol_whitelist file,http,https,tcp,tls -i 'https://source-bucket.s3.amazonaws.com/1.mp4' -ss 5 -t 10 -loglevel 48 -y -avoid_negative_ts 1 -acodec copy /tmp/output.mp4


  


  It gives following output :

  So, its not going beyond this : 'Opening 'https://source-bucket.s3.amazonaws.com/1.mp4' ; for reading\n'

  


  And after this, it immediately gets out. Need suggestions, where its going wrong. Same command working fine on local computer.

  


  I tried cloudfront and signed url as well, as mentioned in this post : How to read remote video on Amazon S3 using ffmpeg. But it doesnt work with url. Only working when downloaded into tmp folder.

  


  Following is the final log, which you can see is no timeout. It actually finish function execution within 2-3 seconds. I have timeout set for 15 mins to the function which is maximum :

• Multiple trims to a video using ffmpeg generating video with shorter duration than expected [closed]

  9 septembre 2024, par Gerardo

  I have an application that given a video it trims multiple parts of that video using ffmpeg. Each part is cropped, scaled and then concatenated to generate a single video.

  


  To share an example, I have a video of 1 minute and 44 seconds of duration and 60 fps. My goal is to trim 3 parts of the video :

  


  

  • First one between seconds 0 to 44.666

  


  • Second one between seconds 44.666 to 74.349

  


  • Third one between seconds 74.349 to 103.985

  


  


  The ffmpeg command I use to achieve that is the following one :

  


  ffmpeg -y -hide_banner -i bg_720_1280.png -i error.mp4 -filter_complex "
[1:v]trim=0.0:44.666,setpts=PTS-STARTPTS,crop=405.0:720.0:437.5:0.0,scale=-2:1280.0[crop_1_0_v];
[1:a]atrim=0.0:44.666,volume=1.0,asetpts=PTS-STARTPTS[crop_1_0_a];
[0:v][crop_1_0_v]overlay=enable='between(t,0,44.666)':x=0.0:y=0.0[crop_1_0_v];
[1:v]trim=44.666:74.349,setpts=PTS-STARTPTS,crop=405.0:720.0:437.5:0.0,scale=-2:1280.0[crop_2_0_v];
[1:a]atrim=44.666:74.349,volume=1.0,asetpts=PTS-STARTPTS[crop_2_0_a];
[0:v][crop_2_0_v]overlay=enable='between(t,0,29.683)':x=0.0:y=0.0[crop_2_0_v];
[1:v]trim=74.349:103.985,setpts=PTS-STARTPTS,crop=405.0:720.0:437.5:0.0,scale=-2:1280.0[crop_3_0_v];
[1:a]atrim=74.349:103.985,volume=1.0,asetpts=PTS-STARTPTS[crop_3_0_a];
[0:v][crop_3_0_v]overlay=enable='between(t,0,29.636)':x=0.0:y=0.0[crop_3_0_v];
[crop_1_0_a][crop_2_0_a][crop_3_0_a]concat=n=3:v=0:a=1[a];
[crop_1_0_v][crop_2_0_v][crop_3_0_v]concat=n=3:v=1:a=0[outv];
[a]amix=1:duration=longest[outa]" -map "[outv]" -map "[outa]" -vcodec libx264 -acodec aac -sws_flags lanczos -pix_fmt yuv420p -crf 17 -preset superfast -r 60 test.mp4


  


  Running this command it generates a video of 11 seconds of duration and I'm unable to understand it. What is wrong with the command ? Also I'm open to recommendations of the ffmpeg command in case you find another way more efficient or performant.

  


  I'm using the following FFMPEG version :

  But I got the same issue with static ffmpeg builds

  


  The file bg_720_1280.png is just a transparent image of resolution 720x1280. I think I could achieve the same by using nullsrc filter with that resolution instead of using this background image.

  


• The problem with pydub.AudioSegment.from_file (ffmpeg)

  7 septembre 2024, par akkoolda

  I'm trying to make a normal voice recording discord. When I try to convert an Audio Data object, an error occurs. I've already tried everything I can, I can't solve the problem.

  


  Here is the code, the error occurs in the seg variable :

  


  async def once_done(sink: discord.sinks.MP3Sink, channel: discord.TextChannel, *args):
        words_list = []
        audio_segs: list[pydub.AudioSegment] = []
        longest = pydub.AudioSegment.empty()
        files: list[discord.File] = []

        for user_id, audio in sink.audio_data.items():
            try:
                payload: FileSource = {
                    "buffer": audio.file.read(),
                    "mimetype": "audio/mp3"  # Указываем тип аудиофайла
            }

                #audio.on_format("mp3")
                seg = pydub.AudioSegment.from_file(audio.file, format="mp3")

Solving the error, how else can you normally record user audio


  


  How can I fix this, or maybe there are some other options ?
