• FFmpeg get frame rate

  22 septembre 2021, par zhin dins

  I have several images and I am reproducing them in 78.7ms, I am creating like the 80s video effect. But, I am unable to find the correct ms, and this images with the original videos are unsync.

  


  I dumped the video to images using this command => ffmpeg -i *.mp4 the80effect/img-%d.jpg And now, I have 48622 frames. The video FPS is 24

  


  So, 48622/24 = 2025 +- I cannot use 2025ms since those images will load very slow. And the and the approximate value is 78.7ms per frame/image

  


  How can I find the correct value ? The video duration in seconds is 2026. I have tried all math to find this but I'm failing. How many images (one frame) per msCould you help me ? Thank you.

  


• voiceclient.play(discord.FFmpegPCMAudio) doesn't play any audio

  23 septembre 2021, par mm3239

  I'm trying to create a private music bot. It joined voice channel, but no sound came out and queue didn't worked. My play function is like this :

  


  async def play_music(self):
    if len(self.music_queue) > 0:
        self.is_playing = True

        index = self.music_queue[0][0]['index']

        #connecting to voice channel
        if not self.vc.is_connected():
            self.vc = await self.music_queue[0][1].connect()
        else:
            await self.vc.move_to(self.music_queue[0][1])

        self.music_queue.pop(0)

        self.vc.play(discord.FFmpegPCMAudio(self.music_files[index], **self.FFMPEG_OPTIONS), after=lambda e: self.play_next())


  


  When I execute the file, it should work like this :

  


  Me: /play abc.mp3
Bot: Song added to queue.
*abc song plays in voice channel*
Me: /play def.mp3
Bot: Song added to queue.
Me: /play ghi.mp3
Bot: Song added to queue.

Me: /queue
Bot: def.mp3
     ghi.mp3


  


  However, in reality, Discord :

  


  Me: /play abc.mp3
Bot: Song added to queue.
*silence*
Me: /play def.mp3
Bot: Song added to queue.
Me: /play ghi.mp3
Bot: Song added to queue.

Me: /queue
Bot: No music in queue.


  


  Console :

  


  music found!&#xA;[[{&#x27;index&#x27;: 2, &#x27;title&#x27;: &#x27;abc.mp3&#x27;}, <voicechannel>]]&#xA;music found!&#xA;[[{&#x27;index&#x27;: 0, &#x27;title&#x27;: &#x27;def.mp3&#x27;}, <voicechannel>]]&#xA;&#xA;music found!&#xA;[[{&#x27;index&#x27;: 1, &#x27;title&#x27;: &#x27;ghi.mp3&#x27;}, <voicechannel> position=5 bitrate=64000 user_limit=10 category_id=790202432072187909>]]&#xA;</voicechannel></voicechannel></voicechannel>

  


  I can see something's wrong(abc and def prints shorter message in console, middle part of message is skipped), but as you can see, it doesn't raise any error or exception. Could anyone please help me correct my code ? I'm completely stuck, and it would be really appreciated if someone could tell me what the problem is.

  


• FFMpeg with PHP-7.0 on Ubuntu

  25 octobre 2018, par Gabriel Bueno Lemes da Silva

  I have a NGINX server with PHP-7.0 and I would like to install the ffmpeg-php extension. I’ve been trying for a few days now and in many ways.

  The method that worked so far was compiling ffmpeg (https://ffmpeg.org/releases/ffmpeg-4.0.2.tar.bz2) manually, but when trying to compile ffmpeg-php (https: // sourceforge. net / projects / ffmpeg-php / files / ffmpeg-php / 0.6.0 / ffmpeg-php-0.6.0.tbz2 / download) I am encountering the following error message :
