Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Concat with short inpoint and outpoint differences leads to long still image in the final video
11 mai 2017, par P. DeeI create a
list.txt
withinpoint
andoutpoint
markers, that are sometimes close - down to 0.5s in difference with GoPro MP4-files.Then I use
-y -f concat -safe 0 -i list.txt -c:v libx264 -c:a aac -af aresample=async=1 -pix_fmt yuv420p "filename.mp4"
.What happens is that the smaller the differences between
inpoint
andoutpoint
are, the longer a still image of the first video image is shown. Recently I had a 60 seconds long video and 30 seconds of it at the beginning were just the same image.How do I need to change my command ?

FFmpeg Not Creating or Appending Final HLS Segment When RTMP Stream Ends [closed]
14 août 2024, par ArjitI am transcoding an RTMP stream to HLS using FFmpeg, and I have a problem : when the RTMP stream finishes, the last segment, which does not reach the target duration, is not created as a
.ts
file. Consequently, this last segment is not appended to the playlist file.

command :


fmpeg -i rtmp://localhost:1935/live/xyz -c:v libx264 -preset veryfast -b:v 400k -c:a aac -b:a 64k -s 426x240 -hls_playlist_type event -hls_time 10 -hls_list_size 0 -hls_segment_filename jack/240p_%03d.ts jack/240p.m3u8



I expected that when the RTMP stream ends or when i terminate that FFmpeg process, FFmpeg would create a .ts file for the last segment, even if it is shorter than the target duration (10 seconds), and that this segment would be appended to the playlist (output.m3u8).
