Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

FFMPEG drops supposedly corrupt frames from original video while transcoding using h264 encoder
19 février 2019, par t6nandI am using h264 for optimising MP4 for web. I have a video which has some supposedly corrupt frame(s) within it’s initial 1-2 seconds. (Frame provided below)
On transcoding using :
ffmpeg -i orig.mp4 -c:v libx264 -crf 25 -vf scale="-2:min(ih\,720)" -b:v 600K -g 90 -c:a libfdk_aac output.mp4The output MP4 has these frames dropped out and I have my output with it’s start about 1 to 2 seconds delayed from original video, thus resulting in overall less time duration in output video.
Moreover, most media players also skip these frames in playback (like quicktime player, etc). But VLC media player was able to play this video without skipping these frames.
Is there a way to not drop frames using ffmpeg ? And if possible is it possible to identify and fix these frames in a video ?
Note : I tried encoding same video using AWS Elastic transcoder which actually fixed these frames (Frame provided below) :
