I'm trying to use ffmpeg to play with a lot of different video files and
formats, so I'm using videos from this page:
http://download.wavetlan.com/SVV/Media/HTTP/http-3gp.htm
There's one specific with a curious problem.
http://download.wavetlan.com/SVV/Media/HTTP/3GP/QuickTime/Quicktime_test3_3GPv5_H263_xbit_176x144_AR1
.22_30fps_KF1in30_32kbps_AMR-NB_Mono_8000Hz_6.7kbps.3gp
If I try to get a PNG from this video, it works just if seconds is less
than 43.
{{{
% ffmpeg -y -ss 00:40 -i Quicktime_test3_3GPv5_H263_xbit_176x144_AR1
.22_30fps_KF1in30_32kbps_AMR-NB_Mono_8000Hz_6.7kbps.3gp -vframes 1
output.png
works for me
% ffmpeg -y -ss 00:43 -i Quicktime_test3_3GPv5_H263_xbit_176x144_AR1
.22_30fps_KF1in30_32kbps_AMR-NB_Mono_8000Hz_6.7kbps.3gp -vframes 1
output.png
works for me
% ffmpeg -y -ss 00:44 -i Quicktime_test3_3GPv5_H263_xbit_176x144_AR1
.22_30fps_KF1in30_32kbps_AMR-NB_Mono_8000Hz_6.7kbps.3gp -vframes 1
output.png
does not works for me
It says: Output file is empty, nothing was encoded (check -ss / -t /
-frames parameters if used)
