ffmpeg -f segment fails after 30 minutes
8 mars 2018, par Musashi SakamotoWhen I used command below to convert video stream received from named pipe into .ts file which is HLS formatted,
sudo ffmpeg -i named_pipe.mkv \
-c:v libx264 -r 10 -g 30 -map 0 \
-qmin 18 -qmax 30 \
-f segment -segment_format mpegts -segment_time 3 \
-segment_list list.m3u8 \
-segment_list_type hls\
-segment_list_size 20 -strftime 1 \
%Y-%m-%d_%Hh%Mm%Ss.tsIt stops working with the speed gradually going down after about 30 minutes.
Here is the log right before it stopped working.*** dropping frame 2461 from stream 0 at ts -11787

FFMpeg Split MP4 Clip Without Re-Encode | Out of Sync
28 février 2018, par sword1stI want to split mp4 clip for certain seconds but i don’t want to re-encode cuz my cpu isn’t so good it’s take so much time. When i try this code with encode :
ffmpeg -i clip.mp4 -ss 00:00:25 -to 00:01:20 cutted.mp4
it’s working perfectly but i don’t want to re-encode. So i try this code :
ffmpeg -i clip.mp4 -ss 00:00:25 -to 00:01:20 -c copy cutted.mp4
it’s playing perfectly in media player with a couple blank seconds at first it’s no problem i can cut these blank seconds when i editing it. But real problem is i can’t edit that clip in premiere pro cuz it’s out of sync. What can i do for fix it ? Any ffmpeg feature for that ? Thanks for all help !
Here ffmpeg output :
C:\Users\winuser>ffmpeg -i "D:\clips\clip_4579\clip.mp4" -ss 00:03
:00 -to 00:03:30 -c copy "D:\clips\clip_4579\renderless1.mp4"
