• ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]

  14 novembre 2024, par danielRICADO

  using ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8

  


  std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
                         " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
                         " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
                         " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
                         ts_file_pattern + " -f hls " + m3u8_file;


  


  I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available

  


  bool is_h264_v4l2m2m_available() {
    std::string result = exec_command("ffmpeg -encoders 2>&1");
    return result.find("h264_v4l2m2m") != std::string::npos;
}


  


  if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.

  


  other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

• 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:
Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/core.py", line 85, in wrapped

    self.pid = _posixsubprocess.fork_exec(

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

  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.
