Anomalie #3299 : Génération d’urls en boucle avec noms d’objets longs
16 octobre 2014, par Guillaume FahrnerJe pense que c’est plus un soucis d’implémentation qu’autre chose. J’ai réglé mon problème de la manière suivante :
1) implémenter le pipeline objet_compte_enfants pour l’objet concerné, dans mon cas
/** * Compte intégrant les challenge dans le nombre d’objet d’une rubrique */ function ctf_alltheday_objet_compte_enfants($flux)
if ($flux[’args’][’objet’] == ’rubrique’)
$flux[’data’][’machines_virtuelles’] = sql_countsel(
’spip_machines_virtuelles’,
array(
’id_rubrique = ’.intval($flux[’args’][’id_objet’])
)
) ;
return $flux ;
2) ajouter la configuration adéquate a la configuration des URLs choisi, dans mon cas :
$GLOBALS[’url_arbo_parents’]=array(’challenge’=>array(’id_rubrique’,’rubrique’)) ;
$GLOBALS[’url_arbo_types’]=array_merge($GLOBALS[’url_arbo_types’], array(’challenge’=>’’, ’solution’=>’’)) ;Une fois la "configuration" mise en place correctement : plus aucun soucis ,-)

FFmpeg error while converting from MP4 to MP3 in Python
4 février 2024, par Jack142When I try to convert videos from a YouTube playlist, it gives me an error :




File "C :\Users\fonti\AppData\Local\Programs\Python\Python310\lib\site-packages\ffmpy.py", line 106, in run
raise FFRuntimeError(self.cmd, self.process.returncode, out[0], out[1])
ffmpy.FFRuntimeError :
C:/ffmpeg/bin/ffmpeg.exe -i "Nightcore - To Be Human // lyrics.mp4" "Nightcore - To Be Human // lyrics.mp3"exited with status 1



The code I'm using :


from pytube import Playlist
import ffmpy
from ffmpy import FFmpeg

playlistLink = input("Introduz o link da Playlist: ")
playlist = Playlist(playlistLink) 

diretório = 'E'
while diretório != 'M' and diretório != 'V':
 diretório = input("Vais baixar música ou vídeos? (M/V)")
 if diretório == 'M':
 downloadDirectory = "C:/Users/fonti/Documents/Projetos Python/Youtube/Músicas"
 elif diretório == 'V':
 downloadDirectory = "C:/Users/fonti/Documents/Projetos Python/Youtube/Vídeos"

print("Número total de vídeos a baixar: ", len(playlist.video_urls)) 

print("\n\n Links dos vídeos:\n")

for url in playlist.video_urls:
 print(url) 

def MP3():
 for video in playlist.videos:

 audio = video.streams.get_audio_only()
 
 audio.download(downloadDirectory)

 videoTitle = video.title
 
 new_filename = videoTitle + '.mp3'
 default_filename = videoTitle + '.mp4'
 
 print(default_filename+'\n\n'+new_filename)

 ff = ffmpy.FFmpeg(
 executable = 'C:/ffmpeg/bin/ffmpeg.exe',
 inputs={default_filename : None},
 outputs={new_filename : None}
 )
 ff.run()


def MP4():
 for video in playlist.videos:
 print('Downloading : {} with url : {}'.format(video.title, video.watch_url))
 video.streams.\
 filter(type='video', progressive=True, file_extension='mp4').\
 order_by('resolution').\
 desc().\
 first().\
 download(downloadDirectory)

escolha = 'E'
while escolha != 'V' and escolha != 'A':
 escolha = input("Queres formato de vídeo ou áudio (V/A)? ")
 if escolha == 'V':
 MP4()
 elif escolha == 'A':
 MP3()
 else:
 print("Escolha inválida")


If I try to download the videos from the playlist, it works fine. But when I try to download the audios, it gives me the error.

ffmpeg -master_pl_name grabbing the correct codec
10 juin 2020, par user1503606I am using the following ffmpeg command to generate my hls playlist with the FFmpeg option -master_pl_name set.



ffmpeg -i becky.mov \
-i becky.mov \
-i becky.mov \
-i becky.mov \
-s:v:0 1920x1080 -c:v:0 libx264 -b:v:0 4000k \
-s:v:1 1280x720 -c:v:1 libx264 -b:v:1 2000k \
-s:v:2 854x480 -c:v:2 libx264 -b:v:2 1000k \
-s:v:3 640x360 -c:v:3 libx264 -b:v:3 600k \
-c:a:0 copy \
-map 0:a -map 0:v -map 1:v -map 2:v -map 3:v \
-var_stream_map "a:0,agroup:audio v:0,agroup:audio v:1,agroup:audio v:2,agroup:audio v:3,agroup:audio" \
-threads 0 -f hls -movflags frag_keyframe -hls_flags single_file+independent_segments \
-hls_segment_type fmp4 -hls_list_size 0 -hls_time 10 -hls_allow_cache 1 \
-master_pl_name master.m3u8 -y burnt/demo2/list_%v/master.m3u8



This is fine and will give me a master.m3u8 file that looks like this.



#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=1047200,RESOLUTION=640x272,CODECS="avc1.4d4815,mp4a.40.2"
pl_0.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=1788600,RESOLUTION=842x358,CODECS="avc1.4d481e,mp4a.40.2"
pl_1.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=3436400,RESOLUTION=1280x544,CODECS="avc1.4d481f,mp4a.40.2"
pl_2.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=6096200,RESOLUTION=1920x816,CODECS="avc1.4d4828,mp4a.40.2"
pl_3.m3u8



The problem that I have is I need to generate my master.m3u8 file manually as I am also generating subtitles and audio description groups. I am using ffprobe to do this.



But I am not sure how to get the CODECS="avc1.4d4815,mp4a.40.2" value to then insert it into my master.m3u8 file.



My ffprobe output doesn't seem to give any of that information here is the full output.
