• UIImage setImage crash

  13 juin 2014, par Arton

  I implemented a video player with ffmpeg. Each frame is decoded successfully and can be saved to a valid jpg file and can be show in UIImageView when running in emulator. However, the memory is unbounded growing when I run my app in emulator. Moreover, the app will crash after excuting p_diaplayNextFrame 2 times when running on device. If I comment self.imageView.image = frame;, memory is not leaked and app is not crashed in emulator or on device.

  -(void)p_displayNextFrame
  
  {
  
      ZCVFrameSec *frameSec = [video getNextVideoFrameSec];
  
      UIImage *frame = [frameSec toUIImage];
  
      static int fi = 0;
  
  
  
      NSAssert( [NSThread isMainThread], @"Fatal error: must be main thread" );
  
      NSString *fileName = [Utilities documentsPath:[NSString stringWithFormat:@"image%06d.jpg",fi++]];
  
      NSLog(@"p_displayNextFrame write image file: %@",fileName);
  
  
  
      // frame is saved successfully as jpg, I can view it
  
      [UIImageJPEGRepresentation(frame, 0.7) writeToFile:fileName atomically:YES];
  
  
  
      // leak(but not crash) in emulator, crash on device
  
      self.imageView.image = frame;
  
  
  
      double delayInSeconds = 0.05;//1/30.0;
  
      dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
  
      dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

• How do I make my discord bot play music by using youtubedl's search function instead of url ? (Python)

  28 septembre 2021, par PypypieYum

  I want it to search for the video and play it, how can i change the following code to achieve that ? Every time I use the ytsearch function in ytdl, I notice that it only searches for the first word of the title and download it, however, it causes error later on and do nothing.

  


  @commands.command()
    async def play(self, ctx, url):
        if ctx.author.voice is None:
            await ctx.send("You are not in a voice channel!")
        voice_channel = ctx.author.voice.channel
        if ctx.voice_client is None:
            await voice_channel.connect()
        else:
            await ctx.voice_client.move_to(voice_channel)

        ctx.voice_client.stop()
        FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
        YDL_OPTIONS = {'format':"bestaudio", 'default_search':"ytsearch"}
        vc = ctx.voice_client

        with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
            info = ydl.extract_info(url, download=False)
            if 'entries' in info:
              url2 = info["entries"][0]["formats"][0]
            elif 'formats' in info:
              url2 = info["formats"][0]['url']
            source = await discord.FFmpegOpusAudio.from_probe(url2, **FFMPEG_OPTIONS)
            vc.play(source)


  


  And this is the error message :

  


  Ignoring exception in command play:

    self.pid = _posixsubprocess.fork_exec(
TypeError: expected str, bytes or os.PathLike object, not dict

The above exception was the direct cause of the following exception:

    raise CommandInvokeError(exc) from exc

  Issue is that the program needs to be restarted every X minutes so that the list of media will update on it’s own. However, upon a restart, ffmpeg goes crazy and starts to spam a batch window under it’s name repeatedly over and over again without stopping. The only way out of it is to restart my computer.

  I’ve tried to use PM2, Forever, Supervisor. Nodemon afaik won’t auto restart.
