• Saving H.264 RTP stream without re-encoding ?

  13 avril 2012, par Gene Vincent

  My C++ application receives a H.264 RTP video stream.

  Right now it decodes the stream, saves it into a YUV file and later I use ffmpeg to re-ecode the file into something suitable to watch on a Windows PC (eg. Mpeg4 AVI).

  Shouldn't it be possible to save the H.264 stream into a AVI (or similar) container without having to decode and re-encode it ? That would require some H.264 decoder on the PC to watch, but it should be much more efficient.

  How could that be done ? Are there any libraries supporting that ?

• I'm having an issue with my discord bot playing audio from a youtube url

  19 avril 2022, par Alex Graeca

  sync def hog():
channel = bot.get_channel(964971002289356893)
url = 'https://www.youtube.com/watch?v=GyRmkAfpCOM'
await asyncio.sleep(1)
voice_channel = bot.get_channel(int(964971002289356893))
vc = await voice_channel.connect()
#vc.play(discord.FFmpegPCMAudio('C:/Users/alexa/Downloads/hogrider.mp3'))
vc.play(discord.FFmpegPCMAudio(source='https://www.youtube.com/watch?v=GyRmkAfpCOM', executable='ffmpeg.exe'))
while vc.is_playing():
    await asyncio.sleep(5)
await vc.disconnect()


  


  It works fine with the audio file from my laptop, but I want to play it from a youtube link.
It gives me an error :
https://www.youtube.com/watch?v=GyRmkAfpCOM : Invalid data found when processing input

  


  Thank you in advance

  Cela vient du fait que $flux[’args’][’date’] du pipeline optimiser_base_disparus est valeur qui est déjà passé par sql_quote(). (cf. fonction `optimiser_base_disparus` du code, qui contient la ligne (`$mydate = sql_quote(date("Y-m-d H:i:s", time() - $attente)) ;`)

  Or la plupart des plugin(-dist) qui utilise ce paramètre $flux[’args’][’date’] pour construire leur requete passe en sql_quote. Du couip double sql_quote.

  La question que je me pose : faut-il corriger les plugins(-dist) ou le core ?
