1526,"Got ""Truncating packet of size 4096 to 1"" at files with long durations when ""-ss"" at the near the end of file",vladget,,"Summary of the bug:
I'm trying to encode video encoded from dv in avi container to x264 in mp4 container but got error... (please see output below)

If I decreasing start time of input stream from 00:52:37.640 to 00:42:37.640 or lower it start converting.. I have tried to move ""-ss"" to the end(before output argument) it will shown no errors but it taked to much time for transcoding...


How to reproduce:
{{{

-ss 00:52:37.640 -t 367 \
