• Terminal command to upgrade FFMPEG

  14 avril 2023, par Savvy Turtle

  Everything is still installed but once I upgraded my server from CentOS 7.6 to Cloud Linux FFMPEG does not seem to work anymore.

  


  When I go and debug it in the admin section where you upload a test video and hit debug it shows a toast to upload a video. and on the front end of https://turtle.tube/ users upload a video and it gets stuck at 100% upload and processed.

  


  So I'm wondering whether I need to ugrade FFMPEG to work with Cloud Linux update or If I need to restart it.

  


  Any help would be great thanks.

  Checked Version, looked for terminal command to upgrade FFMPEG to latest stable release of : FFmpeg 5.1.3 "Riemann" or FFmpeg 6.0 "Von Neumann" but have not figured out the command to upgrade yet.

  


  nor the command to restart FFMPEG if that even exist.

  


  Current version of FFMPEG shows :

  


  ffmpeg -version

• How to generate HLS stream multiple qualities (Representations) while capturing webcam

  27 janvier 2023, par LUKA TADIĆ

  I want to generate multiple qualities (Representations) for HLS stream while capturing from webcam. I am using ffmpeg_streaming python package. I can generate one quality (Representation) at a time, but when i try to generate more than one, I get this error :

  This is the code :

  


  import ffmpeg_streaming
from ffmpeg_streaming import Formats,Bitrate, Representation, Size 

video = ffmpeg_streaming.input('Fantech Luminous C30', capture = True)

_360p  = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p  = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p  = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))

hls = video.hls(Formats.h264(),hls_list_size=10, hls_time=5)
hls.flags('delete_segments')
hls.representations(_360p, _480p, _720p)
hls.output('C:\\Users\\ltadic\\Desktop\\camera_stream\\hls1.m3u8')


  


  I was expecting to get _360p, _480p and _720p qualities, but my program crashes. If I try same thing for DASH stream, I generate these qualities without any problem.
