Thanks for checking.
I also check the AVFMT_FLAG_FAST_SEEK flag with parsing headers,
to fill the seektable into index entries only if AVFMT_FLAG_FAST_SEEK flag
is on.
If the AVFMT_FLAG_FAST_SEEK flag is not enabled, it will seek in original
way.

You could use the AVFMT_FLAG_FAST_SEEK flag. (It's a flag set on
Is it acceptable to provide an option for different methods
between accuracy seek and fast but inaccurate.
For example, mp3dec having "usetoc" option to seek by toc.

I inspected what filter produces with constant 0.5 mono input and
found it is repeating after each sample_rate number of samples.

Just wondering. Is there a reason that the size of s->table is
(inlink->sample_rate) and not (1.0 / inlink->sample_rate) ?
Thanks!

I found the generic seek will invoke the flac_read_timestamp function.
It read exta packet will slow down the seek time

Hi Hendrik,
I move the index data into AVStream, but seeking is slow. (it try to
download many data).
Is there something wrong ?

You should store the index in the AVStream index_entries field, that
way you don't need to
flacdec is not supported fast-seek yet.
changes:
1. parse the seekpoint from metadata block
2. add seek callback to look up seek position
