Comment (by jbvsmo):

 Hi, I'm working on a project with multiple ffmpeg processes converting
 parts of a video at the same time and the speedups I'm achieving are
 amazing.

 But, for this to work, I rely on fast seek, otherwise the slow seek makes
 the method useless. The problem is that

 {{{
 ffmpeg -ss time -i input -ss 0 output
 }}}

 doesn't always give me the right frame!

 I found in the mail list ([http://ffmpeg.org/pipermail/ffmpeg-
 user/2012-August/008767.html here] and [http://ffmpeg.org/pipermail
 /ffmpeg-user/2012-August/008769.html here]) that ffmpeg may reach a frame
 after the specified time and never go back.

 Are there any chances of a really accurate and fast seek in a single
 option? BTW, seek by frame number is possible?

 The ffmpeg version I'm using is from git on September 12 (2 weeks before
 ffmpeg 1.0).
