 Yes, that's why I said that at the bistream level it was probably not valid.
 But inside vlc, on the block_t that hold the PES, we may set them to non 0
value (but without the pts/dts set inside the pes header). But I do not know
if it will have side effects. (on vlc code)
 Using unlimited PES might be better.
