You should store the index in the AVStream index_entries field, that
way you don't need to

It would be great if we could run our new fate seek tests on this.

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

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

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

Sorry, I meant to type (1.0 / s->freq). This is one wavelength.

I inspected what filter produces with constant 0.5 mono input and
found it is repeating after each sample_rate number of samples.
Please do not top post.

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.

You could use the AVFMT_FLAG_FAST_SEEK flag. (It's a flag set on

Hello!
Attached patch makes the ICO demuxer return EOF instead of EIO when the end
of the file is reached. Currently, if you try to parse an ICO file, it will
always result in ffmpeg outputting an error because of this.

I do it with AVFMT_FLAG_FAST_SEEK flag.

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.
