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 (...)

Getting error "DLL load failed while importing rect : %1 is not a valid Win32 application" while importing package
17 août 2020, par Sagar DonadkarI am using cython package to call Cpp API and in my cpp code i am using ffmpeg library and able to build my code successfully using bellow command

Trying to convert an RTSP stream to a HSL file, but get a "Failed to Open Segment" error
1er juin 2021, par Alvydas JuodikisThese are the linux commands I ran on ubuntu 20.04 to convert an rtsp stream to a HLS file. I was trying to then display it onto my html webserver to run a live video but I'm stuck at an error.

 Home/Desktop/fmpegsolution/%3d.ts
</my>

I'm using an example from this link :
https://girishjoshi.io/post/ffmpeg-rtsp-to-hls/


I try to generate my file into a directory located in my desktop called fmpegsolution (hence the output path Home/Desktop/fmpegsolution)


The error :


When running this on terminal, the error comes out to :

[segment @ 0x558c82e11ec0] Opening 'Home/Desktop/fmpegsolution/000.ts' for writing [segment @ 0x558c82e11ec0] Failed to open segment 'Home/Desktop/fmpegsolution/000.ts' Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

My issue is related to the folder or directory but it definitely exists. I even tried creating a "%3d.ts" blank file (000.ts) but that had no effect. Could use some help. Thanks for your time.
