MediaSPIP Player : problèmes potentiels
22 février 2011, parLe lecteur ne fonctionne pas sur Internet Explorer
Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...) -

Concatenate audio files using ffmpeg
4 juin 2021, par user13962029I am trying to concatenate ac3 and aac using ffmpeg.


ffprobe of jpn_op.m4a :


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'jpn_op.m4a':
Metadata:
major_brand : M4A 
minor_version : 512
compatible_brands: M4A isomiso2
encoder : Lavf58.76.100
Duration: 00:01:17.28, start: 0.000000, bitrate: 224 kb/s
Stream #0:0(jpn): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, stereo, fltp, 224 kb/s (default)
Metadata:
 handler_name : SoundHandler
 vendor_id : [0][0][0][0]
Side data:
 audio service type: main



ffprobe of eng_nop.m4a


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'eng_nop.m4a':
Metadata:
major_brand : M4A 
minor_version : 512

Metadata:

 vendor_id : [0][0][0][0]



I tried this :


ffmpeg -f concat -i concat_files.txt -c copy final.m4a -y



concat_files.txt contains :


file 'jpn_op.m4a'
file 'eng_nop.m4a'



ffprobe of final.m4a


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'final.m4a':
Metadata:
major_brand : M4A 
minor_version : 512

But, there is silent in place of 2nd file in final.m4a

Queuing up videos for live stream
5 avril 2014, par Abdul AliWould first like to tell that am new to streaming and ffmpeg.
Would try to explain scenario as much as possible.
A web service is intended to receive chunks of video from a user. those chunks need to be simultaneously sent to the web for live streaming for a seamless viewing.
So the videos need to be queued up for streaming to the web so that it looks like a long single video. and the strict requirement is not to make any temp file on disk.
Did read something about pipes but am completely alien to that concept as well.
Kindly tell how / whether this can be achieved from FFMPEG or any other free tool .
Language used is PHP . The received videos also need to be saved to disk in parallel for new users to see from start.
