FFmpeg concat creating corrupted video part (Media Info provided)
6 mai 2022, par krvI am using concat to join a list of video files with the following command


ffmpeg -f concat -safe 0 -i filesList.txt -c copy output.mp4 



The issue here is that there are a few files that were recorded in slow motion on my phone. The slow-motion files have the same frame rate as the other files.


But when concatenated the part where the slow-motion files are concatenated appears to be frozen / glitch (it does not play a single frame).


I am able to seek forward and backward the part that does not play. So the portion of the video that contained normal files plays and as soon as the slow-motion video comes, nothing plays, and when a normal file comes it starts playing again.


I am attaching the media Info of both files

FFMPEG - How to pipe RMS_level and pts_time metadata without generating unwanted metadata
6 février 2020, par Tovi NewmanI am trying to find the loudest (highest rms_level) moment in an audio file, but I need to pipe the metadata rather than write to a file.
I converted the answer found here : [https://superuser.com/questions/1183663/determining-audio-level-peaks-with-ffmpeg][1]
By removing the write to file command and adding a pipe.
Here’s what I’ve got.ffmpeg -i loudSoft.mp3 -af astats=metadata=1:reset=1,ametadata=print:key=lavfi.astats.Overall.RMS_level -f null - 2> result.txt
The only problem is, now I’ve got a lot of unwanted metadata before and after the RMS_level and pts_time data as well as
[Parsed_ametadata_1 @ 0x7f9d42c37500]
being printed on each line. None of that was being written when I was writing to a file instead of piping. (all I need is the time and the rms.)Here is an abridged version of what I get when I write to file :
frame:0 pts:0 pts_time:0
