hi all i'm downloading some long videos from a rtmps url, it works
perfectly but when network hiccups , download stopped before it finishes,
basically i want to check the already downloaded unfinished .mp4 video
length via ffprobe, then pass -ss to the ffmpeg command line as the
save another file, at last concatenate these files.
the problem is the fast and accurate seeking seems not working . i used the
latest windows static 64bit build from
fast seeking seems working : ( download starts immediately , seeking is
ffmpeg -ss 00:30:00 -i "rtmps://xxx option=xxx" out.mp4
accurate seeking seems working too: ( download only start after 30min ,
it's slow )
ffmpeg -i "rtmps://xxx option=xxx" -ss 00:30:00 out.mp4
but the hybrid fast and accurate seeking is not working
ffmpeg -ss 00:29:00 -i "rtmps://xxx option=xxx" -ss 00:01:00 out.mp4
This is suggested by the wiki page, but it seems has no effect
(download still starts after 29min or 30min)
am i missing something ?
