Description
You can't seek in this file with ffplay: https://educast.fccn.pt/vod/clips/1aw3ugmjz0/quicktime.mov
The file plays fine, but attempts to seek print "error while seeking" and cause audio and video to freeze. Observed with ffmpeg git 20899c54f03c4.
mplayer -demuxer mov can seek in this file. (It fails to seek to key frames correctly, but recovers as more video is decoded.) VLC can seek in it as well.

Immediately after start, I pressed on the curesor right key, which resulted in the "error while seeking" message. You can repeat this multiple times, and it will always print the message. The file is from the URL mentioned above.
Edit: right key, not left

Does seeking work for you with ffmpeg? It fails horribly here, but perhaps you tested differently?
comment:6 Changed 4 months ago by gjdfgh
This seems to work fine, but maybe it's because it somehow selects different streams:
ffmpeg -i quicktime.mov -ss 30 out.mov

- Status changed from reopened to open
- Reproduced by developer set
The following command lines produce output files that are horribly out-of-sync (video starts correctly at ~0:60, audio starts from 0:00)
$ ffmpeg -ss 60 -i quicktime.mov -map 0:1 -map 0:2 -qscale 2 -t 30 out.avi
