16 mars 2017, par Parsa SametFFMPEG will fail to stream from .m3u8 over HTTP. It is pointing to getting an empty playlist whilst it’s not empty. It also points to the following error sometimes :

FFmpeg - Concatenate videos with not know format
22 mars 2017, par JavierI am developing an application.
People upload videos from their mobile, from other places.Using a CMS in PHP (it is the language with which the application is developed) I need to generate a unique video with these partial uploads.
Through FFmpeg I am doing tests, from the command line :
ffmpeg -i concat:IMG_1916.mp4\|IMG_1917.mp4 -c copy videoLoop.mp4
This code when I run it says :

Why not join the 2 ?
The videos to upload, will be of very different formats so I can not define codec.
