FFmpeg stuck on frame 0 during time-lapse conversion with `-ss` start time
2 janvier 2021, par rgovI have a long video that I'd like to speed up into a time-lapse. Following the FFmpeg wiki, I came up with this incantation :



ffmpeg -i IMG_0238.MOV -r 60 -ss 00:04:41 -filter:v "setpts=PTS/60.0" -an output.mp4




It should clip off the first few minutes, then create a new 60fps video file at 60x the speed.



Although it spins all my CPU cores up to 100%, the status bar simply shows
frame= 0 fps=0.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x
and never progresses.


The problem seems related to the
-ss 00:04:41
flag, which specifies the start time ; I want to drop the first 4 minutes 41 seconds of source video. When I omit this option, the video conversion succeeds.


Full log follows.

FFMPEG split video to segments with audio
28 septembre 2020, par Kiril MytsykovI'm tying to split mov file to .ts segments with m3u8 playlist.
All is ok except of audio. Audio doesn't work and it seems that ffmpeg ignores audio stream.


This is my command :


ffmpeg -i stepteen2.mov 
 -c:a aac 
 -c:v libx264 
 -an 
 -map 0 
 -muxdelay 0 
 -muxpreload 0 
 -output_ts_offset 0 
 -segment_time 2 
 -segment_wrap 1000 
 -segment_list_size 0 
 -segment_list temp.m3u8 
 -segment_list_flags +cache 
 -segment_list_type m3u8 
 -f segment 
 temp-%03d.ts



After this command I receive 5 ts segments and m3u8 playlist with segment paths list.
If I open properties of segment files there are no any information in Audio and Video tabs (although video works)


This is output :
