movenc : add movie_timescale option instead of hardcoding 1000
27 avril 2021, par Justin Rugglesmovenc : add movie_timescale option instead of hardcoding 1000
There are cases where using 1000 as the MP4 timescale is not
accurate enough, for example when one needs sample-accurate audio
handling.This adds a new AVOption to the MOV/MP4 muxer to override the
movie timescale, but it still defaults to 1000 to maintain current
default behavior.Signed-off-by : Vittorio Giovara <vittorio.giovara@gmail.com>

ffmpeg error : Unable to find a suitable output format for 'scale=1500:1000'
13 février 2021, par Tomáš Zato - Reinstate MonicaI am trying to convert a bunch of images into a video. The original image resolution is 6000x4000, but if I use ffmpeg to create a video with that resolution, no player can even play it because it's way to huge.


I tried to set the output resolution as such, dividing the input resolution by 4 :


ffmpeg -r 60 -s 1500x1000 -start_number 3790 -i DSC_%04d.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p ../video_lowres.mp4



This had no effect and still produced 6000x4000 video. So instead, I tried this parameter :
scale=1500:1000
The full command I ran :

ffmpeg -r 60 scale=1500:1000 -start_number 3790 -i DSC_%04d.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p ../video_lowres.mp4



But I got this error :


[NULL @ 000002ad897bd9c0] Unable to find a suitable output format for 'scale=1500:1000'
scale=1500:1000: Invalid argument



How can I create a downscaled video from photos using ffmpeg ?

Anomalie #4342 : Erreur 1071 de mysql : Specified key was too long ; max key length is 1000 bytes
7 avril 2020Une autre piste donnée par b_b sur IRC :
- 767 octets est la limite de préfixe déclaré pour les tables InnoDB dans les versions antérieures à la 5.7 de MySQL et dans les versions antérieurs à la 10.2 de MariaDB.
- A partir de la version 5.7 de MySQL et la 10.2 de MariaDB, cette limite a été augmentée à 3072 octets.=> bingo on est en 10.1.41-MariaDB-1 stretch
- L’encodage (latin1, UTF8, UTF8mb4, etc.) peut jouer sur cette taille. Puisqu’en UTF8 un caractère prend 3 octets, il faut diviser la taille disponible par 3 pour trouver la longueur maximale de préfixe d’index. Et par 4 si on utilise UTF8mb4.
=> re bingo on est en utf8
