Comment (by ronag):

 I supposed that mpegts files should be seekable in FFmpeg? In this
 specific case for whatever reason an otherwise working file is not
 possible to seek using FFmpeg.

 It can seek to certain places but not others, e.g. the same command above
 will succeed without errors when instead using "-ss 2".

 It looks like ffmpeg doesn't seek to a keyframe and then decode + skip
 until the correct frame like it does with other container formats. Just
 guessing... or maybe there is a technical reason specific to mpegts which
 makes this not possible?
