The problem with pydub.AudioSegment.from_file (ffmpeg)
7 septembre 2024, par akkooldaI'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")



The error itself

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



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

Multiple trims to a video using ffmpeg generating video with shorter duration than expected [closed]
9 septembre 2024, par GerardoI 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];

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 usingnullsrc
filter with that resolution instead of using this background image.
