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 .

 var thumbnailImagePath = Path.Combine(_rootPath, "thumbnails", thumbnailImageName);
 
 using (Stream fileStream = new FileStream(filePath, FileMode.Create)) {
 
 await file.CopyToAsync(fileStream);

ffmpeg - problem in copying the stream with timed metadata during a split command
15 novembre 2020, par Swarna AnanthanI am facing a problem while copying mp4 along with the data stream in a split command.

Concat mp4 videos and merge their audios to the final output
24 août 2020, par Yevhenii MolodtsovI have several videos and photos and need to merge them with the cross-dissolve effect. The algorithm is next :


- 

- Create videos from images and add silent audio to them (so they will also have a sound stream) :




ffmpeg -y -f lavfi -i anullsrc -loop 1 -i /tmp/media/import-2020-Aug-19-Wednesday-05-40-34/ea5c93fd-d946-4742-b8f7-ea9ae4d43441.jpg -c:v libx264 -t 10 -pix_fmt yuv420p -vf scale=750:1280 /tmp/media/import-2020-Aug-19-Wednesday-05-40-34/ea5c93fd-d946-4742-b8f7-ea9ae4d43441.mp4


- 

- Combine all the videos and audios into one using this command :




ffmpeg 
-i /tmp/media/import-2020-Aug-19-Wednesday-05-40-34/temp_68d437c0-f5e2-4651-b07e-91533480b6ef.mp4

And all works pretty well, but if I have, for example :


- 

- picture
- video
- video
- picture










Then the sound from the second video is mapping to the first picture and sound from the third video to second video. And the third video actually goes without sound.


It seems like it's happening because the silent sound of the first picture is pretty short. An I right ?
If so, how can I increase its duration ?


I would much appreciate any help with this !
