Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...) -
De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
Upload et récupération d’informations de la vidéo source
Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

popen returns output after delay ?
7 février 2013, par ScarfaceI am executing FFMPEG with
popen()to get the result of the process. The main reason I am doing this is so I can stream constant output and build a progress bar.The issue is that the process starts and I receive some initial information. The rest of the information does not appear until after the process is done however. So essentially, the rest of the output (output on the progress) which comes on intervals when the process is going is delayed right before the process and all comes at once after the process is done which is useless.
I need the output to constantly come so I can update a progress bar. If I change 2>&1 to 2> stderr.txt that text file receives output consistently but I would like to receive in php since many processes may be running. Anyone have any ideas on solving this ? It seems noone can figure this out...and it is driving me crazy ! IF anyone helps me figure this out (and actually solve it), I will start a bounty and then accept their answer.

mp4 created by ffmpeg will not play with IPython.display.Video
19 novembre 2020, par AustinI'm creating a mp4 video from jpegs with ffmpeg, using the following command :


ffmpeg -y -threads 0 -f image2 -i jpegs/%05d.jpg -framerate 10 video.mp4

The resulting video will play fine with VLC, but will not play in a Jupyter notebook via :


from IPython.display import Video
Video('video.mp4')


This notebook video functionality has worked for me in the past, so I assume there's something about the codec/mime type that the Video function can't resolve ?



Requested update


New command I've tried :


ffmpeg -y -framerate 10 -i jpegs/%05d.jpg -vf format=yuv420p -movflags +faststart video.mp4

Video still plays fine in VLC and still does not play in Jupyter. I've looked at the duplicates this is marked as and it does not actually seem to be the same issue..


Here's the output (I've removed the framerate and threads flags to simplify) :
