Yes - definitely.
Dithering is only necessary, when converting the data somewhere in between
(e.g. changing the sample rate while it's in 32bit format), as the code in

Hi all!
I am trying to encode at fractional fps. Currently, I can encode video at
29 fps, or 30 fps, but cannot encode at fractional, like 29.97.
I have a video mp4 file with me, probing it gives me the following:

Never tested it, but you should try with those values:
c-time_base.den = 2997;
c-time_base.num = 100;

This should work.
Note however that the 100% correct value for 29.97 is 3/1001,
Yes. I think you can use avformat_open_input_file() on png image to obtain
a properly initialized AVCodecContext. It could simplify the decoding
process.

okay.
1. decode the png using ac_codec_id_png
2. give this
okay. thanks a lot. I will give it a try and revert back if I have any
troubles.

You may need to use avformat_find_stream_info() too.

Hello,
I'm searching for a way to convert an array of values (44100 samples coded
on 16bits each every second) into a series of plot (graph) images (24 per
seconds), and then make a video out of it so that I could have a converter
would it be something like this?

Hi guys!
Thanks for you guidance, adopting your methods seems to have worked just
fine!
@Hendrik Leppkes
Thanks for the insight; I will try to put it to effect as well (might have
to think of a formula first).
