Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Discord FFMPEG audio wont play from yt-dlp
19 mars 2023, par user21236822My question is this : Why isn't my bot playing audio ?


I want the bot to join, play audio from queue, then disconnect without downloading an mp3 file.


I tried using youtube-dl, but I switched to the yt-dlp library after getting errors I couldn't fix.
I am running on Windows 10 locally. All my libraries are up to date.


Here are my ydl_opts and FFMPEG_OPTS :


ydl_opts = {
 'format': 'bestaudio/best',
 'postprocessors': [{
 'key': 'FFmpegExtractAudio',
 'preferredcodec': 'mp3',
 'preferredquality': '192',
 }],
}

FFMPEG_OPTIONS = {
 'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
 'options': '-vn'
} 


Here is where I believe the problem is.


async def play():
 print("Play Called")
 musicPlay()
 # Get message object from initial request
 message = ytLinkQue.get()
 print(f"Message object recieved: {message}")
 voiceChannel = message.author.voice.channel
 vc = await voiceChannel.connect()
 songsPlayed = 0
 
 while not ytLinkQue.empty():
 # Get current song
 currentSong = ytLinkQue.get()[0]
 print(f"Current song: {currentSong}")

 # Get song from Youtube
 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
 # song = ydl.download(currentSong)
 info = ydl.extract_info(currentSong, download=False)
 song = info['formats'][0]['url']

 # Play Song
 vc.play(discord.FFmpegPCMAudio(song, **FFMPEG_OPTIONS), after=lambda e: print('Song done'))

 # Wait until the song has finished playing
 while vc.is_playing():
 print("playing rn")
 await asyncio.sleep(1)
 
 await vc.disconnect()
 musicStop()


When play() is called, here is the output in terminal with my annotations as **** text **** :


>python main.py

On Discord's end, the bot successfully connects then disconnects after 2 second.


Note : I've only included code I think is relevant. Please let me know if I should add anything else to the post, otherwise, here is the github for the project. Code is in main.py.

Thank you in advance !


I've applied the advice from these posts but it still will not play audio :

Rotating gyro data in gopro footage with ffpmeg
2 juillet 2023, par FPV ShenanigansI believe orientation of gyro data in some of my gopro clips is wrong. Reelsteady runs stabilization ok but it results in even worse than initial video shaky effect. I have filmed with gopro in 90 degree with orientation locked .


Is it possible to amend metadata if ffmpeg to fix this ?


the below is an example clip


Metadata :
major_brand : isom
minor_version : 512
compatible_brands : isomiso2mp41
encoder : Lavf60.10.100
Duration : 00:04:30.22, start : 0.000000, bitrate : 119132 kb/s
Stream #0:00x1 : Video : hevc (Main 10) (hvc1 / 0x31637668), yuv420p10le(pc, bt709), 3840x3360 [SAR 1:1 DAR 8:7], 118934 kb/s, 59.94 fps, 59.94 tbr, 60k tbn (default)
Metadata :
handler_name : GoPro H.265
vendor_id : [0][0][0][0]
encoder : GoPro H.265 encoder
timecode : 13:27:43:05
Side data :
displaymatrix : rotation of -90.00 degrees
Stream #0:10x2 : Audio : aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 189 kb/s (default)
Metadata :
handler_name : GoPro AAC
vendor_id : [0][0][0][0]
Stream #0:20x3 : Data : none (tmcd / 0x64636D74)
Metadata :
handler_name : GoPro H.265
timecode : 13:27:43:05


tried this


ffmpeg.exe -i "F :\2023 THE ONLY COPY\Chasing surfers\GX010223.MP4" -c copy -metadata:s:v rotate=90 "F :\2023 THE ONLY COPY\Chasing surfers\GX010223_test.mp4"


but reelsteady can't read metadata from a new video

Using aler9/rtsp-simple-server, able to stream HLS from file but not from ffmpeg's stdin
11 avril 2023, par PowercoderUPD : hehe, it actially works, but in chrome, not mozilla


I want to display programmatically generated stream on a webpage in real time. For this I have rtsp-simple-server with RTSP and HLS enabled. I managed to publish a stream from file with command
ffmpeg -re -stream_loop -1 -i file.mp4 -vcodec libx264 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystreamand see it at http://localhost:8888/mystream.

But when I'm trying to do the same with python from the ffmpeg's stdin, I'm getting infinitely loading video instead of stream and browser console says "Uncaught (in promise) DOMException : The fetching process for the media resource was aborted by the user agent at the user's request". Here is my code :


import random
import shlex
import subprocess
import time

import numpy as np


def main():
 width = 1024
 height = 720
 framerate = 1
 frame_duration = 1 / framerate
 cmd = shlex.split(
 f'ffmpeg'
 f' -y'
 f' -f rawvideo'
 f' -vcodec rawvideo'
 f' -s {width}x{height}'
 f' -pix_fmt bgr24'
 f' -r {framerate}'
 f' -i -'
 f' -r {framerate}'
 f' -force_key_frames expr:eq(mod(n,3),0)'
 f' -vcodec libx264'
 f' -crf 18'
 f' -preset ultrafast'
 f' -tune zerolatency'
 f' -f rtsp'
 f' -rtsp_transport tcp'
 f' rtsp://localhost:8554/mystream'
 )
 ffmpeg_process = subprocess.Popen(cmd, stdin=subprocess.PIPE)
 try:
 while True:
 image = np.full(
 (height, width, 3),
 (
 random.randint(0, 255),
 random.randint(0, 255),
 random.randint(0, 255),
 ),
 dtype=np.uint8,
 )
 ffmpeg_process.stdin.write(image.tobytes())
 time.sleep(frame_duration)
 finally:
 ffmpeg_process.stdin.close()
 ffmpeg_process.wait()


if __name__ == '__main__':
 main()



In the server's logs seems like no bad messages instead of single 404 status (is it just about favicon, right ?)
