[FFmpeg-user] remove error without reencoding

[Richard Bartczak]

Hello,

the following error will be indicated by ffmpeg , libx264 of a video :

Input #0, mpegts, from './Lion of the Desert - Löwe der Wüste.ts':

VLC or a DLNA Device (e.g.: TV)  play this video without visible 
errors.  Perhaps I did cut the video on a NIDR position.

But after compression of this video :

#!/bin/sh
for f in *.ts; do ffmpeg -y -i "$f" -vcodec libx265 -crf 20 -preset slow 
-vf yadif,nlmeans="1.6:7:5:3:3" -c:a copy "$(basename "$f" .ts).mkv";done

Neither VLC nor the TV via DLNA does play the video without visible errors.

Is it possible to remove errors like that, without reencoding the video 
with ffmpeg.

Best regards

Richard
