ffmpeg says "No such file or directory" [closed]
10 octobre 2020, par srvnk

ffmpeg says no such file or directory but the file exists. I want to extract a frame/thumbnail from that video (pre1.mp4). I have installed ffmpeg by
sudo snap install ffmpeg
. My ubuntu version is 18.04.4 LTS. I also triedffmpeg -ss 00:00:01 -i pre1.mp4 -vframes 1 -q:v 2 output.jpg
but same error.

I am using php to generate the thumbnail. I tried functions -
exec
,shell_exec
andsystem
to run the command but same error. After getting error I tried to run the command in terminal but the error is same.

Why am I receiving an error about unterminated %{} near '{localtime' when using ffmpeg
28 juin 2019, par Randy BaileyI am using a line of code to try to record a camera and overlay some timestamp data while im at it.
I have attempted placing a / and an ’ in various locations around the complaint but cant seem to fix the code. The video records fine but there is no timestamp data overlayed.
ffmpeg -i https://CAMERAURL -vf drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf:text='%{localtime:%T}':fontcolor=white@0.8:x=7:y=700 -vcodec libx264 -bsf:a aac_adtstoasc /home/test/StreamDriveway_$now.mp4
Ideally the code should record with no issues. This is a screenshot of whats going in in terminal https://i.imgur.com/mnFmNtd.png
