FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim
23 août 2018, par MayankI am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.
I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.
Can someone please let me know the issue in this command ? Many thanks in advance.

FFMPEG for aws s3 bucket signed url not working in node js
21 août 2018, par ahmed shariefI am trying to create thumbnails from an amazon s3 bucket signed url. I am able to generate thumbnails when i run the command in terminal
ffmpeg -ss 00:00:02 -i "https://test-s3-bucket.s3.ap-south-1.amazonaws.com/user_gallery_assets/5b6936069ac2bf0602085367/gallery/images/5b7be08527641dee8c1f8134.mp4?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=xxxxxxxxx%2F20180821%2Fap-south-1%2Fs3%2Faws4_request&X-Amz-Date=20180821T095101Z&X-Amz-Expires=900&X-Amz-Signature=d7f81f4eed3d6c87c04dc1b0ad06beeb946afa33d417585f57fad72aeadb3ac0&X-Amz-SignedHeaders=host" -vframes 1 -q:v 2 -f image2 output.jpgI am running the above command in terminal and its working fine but when i try to implement the same in node js its showing "no such file or directory error".
