Is the problem you see not reproducible with ffmpeg (the application)?

Hi, using ffmpeg -i input -ss xx:xx:xx -t tt:tt:tt out.mp4 can generated a video staring at xx:xx:xx. That means ffmpeg works ok.

I initially found this issue in our own program which calls ffmpeg API. In our program, the first complete frame read out after seek is 6-7 seconds after the position we seek to, although AVSEEK_FLAG_BACKWARD is specified in av_seek_frame

Hi, using ffmpeg -i input -ss xx:xx:xx -t tt:tt:tt out.mp4 can generated a video staring at xx:xx:xx. That means ffmpeg works ok.

Using ffmpeg -i input -ss x out.mp4 does not seek (so it does not test the issue you see).

Please test ffmpeg -ss x -i input out.mp4: If you see the same issue as with ffplay, please provide the ffmpeg command line that shows unexpected output together with the complete, uncut console output, consider using the "Code block".

comment:4 by hxuanyu, 10 years ago

Hi, below command was run to generate a mp4 video starting from 10th second of original video.

But the first frame of generated b.mp4 appears at 20th second in original video. So ffmpeg also has the problem.

The following command produces a frame approximately 13 seconds from the start:

$ ffmpeg -ss 1 -i AVRO\ Close-up_Ned\ 1_07_08_2010_13_50_05.dvr-ms -vframes 1 out.jpg

The following command produces a frame approximately 72 seconds from the start:

$ ffmpeg -ss 60 -i AVRO\ Close-up_Ned\ 1_07_08_2010_13_50_05.dvr-ms -vframes 1 out.jpg

Seeking backwards by ten seconds with ffplay actually seeks forward a little, seeking by 60 seconds forward seeks >70 seconds, seeking by 60 seconds backwards seeks around 48 seconds backward.
May be related to the starttime.

Attached patch is not correct, it (for example) breaks seeking for the sample from ticket #2572.
