• Extracting Frames form Video in Android [closed]

  2 juillet 2024, par Muhammad Bilal

  I want to extract frames from video and want to change the frames at that point where i extracted the frames.

  


  I have scene apps like Video Status Maker(https://play.google.com/store/apps/details?id=com.krishna.videostatusmaker), Vidify (https://play.google.com/store/apps/details?id=com.beautifullyrical.videomaker). These apps are using template videos. In my view there is a json file behind the video which exactly tells where the frames should be replaced in the video. I checked out the FFmpeg. It is giving me the frames but as i said there must be file which tells where the frames should be replaced. If anyone Knows how this can be done then please guide me. Thanks

  


• Android - Lightweight solution for image video watermarking

  1er décembre 2015, par mtwain

  How to add image on video not using ffmpeg but using some another approach ? What more lightweight solutions exists for simple putting image on video ?

  I know few apps with this functionality that have very small size. What approach do they use ?

• 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")


  


  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 ?
