28 décembre 2020, par Sripathi RajaI have a .net core application which generates video thumbnails for uploaded videos. I am using xabe.ffmpeg for this . The code runs fine in the local system and Iam able to generate the thumbnails . I have containerized this application and pushed it to azure app service . But when the code is deployed on azure app service its throws an error . I have placed the ffmpeg.exe ,ffprobe.exe , ffplay.exe inside a folder ffmpeg in wwwroot folder .
the app service logs give this error


the first line is the path : /app/wwwroot/ffmpeg

 using (Stream fileStream = new FileStream(filePath, FileMode.Create)) {

ffmpeg extract frame and get timestamp based on creation time for each extracted frame in exif or txt
4 août 2021, par ScalingI try to extract frames from a underwater survey video using ffmpeg. the extracted frames should be merged with a gps position based on a timestamp later in the process. the code i use to extract the frames is :



ffmpeg -i GOPR0173.MP4 -qscale:v 2 -r 1 frames/%4d.jpg.


I need a solution to get the real timestamp of the frame based on the survey datetime, so that the timestamp of the frame equals the real time when the video was created. Ideally the timestamp is saved in the images exif or if this is not possible in a seperate textfile and the timestamp is used as name of the files like 2020_01_01_HH_MM_SS.jpg.



My idea is to use the creation_time of the video add the timestamp of the frame to this and store the result in the exif of the extracted frame or if this is not possible in a txt file.



Im new to ffmpeg and really lost and would appreciate any help to solve this task !
If anyone could provide me the necessary code, that would be awesome !
