What the difference between bsf filters? (ffmpeg)

What the difference between 

bsf:v h264_toannexb

and 

bsf:v dump_extra

And what filter should I use, when encode to HLS streaming (mpegts) ?

It depends on the format of the input. If your input is mp4 you should add both (bsf:v dump_extra is probably implied when you used HLS output). If yout input is already ts, you dont need bsf:v h264_toannexb

But really, to answer the question, you need to understand what extradata is, and what annebx b is: http://szatmary.org/blog/25
