also unrelated to this ticket: when you open iff ilbm or iff pbm file and seek
with the mouse then displayed output will change - probably regression since added
seeking support for iff maud

[Carl Eugen Hoyos]

Regression since da8242e.

[Elon Musk]

Really? da8242e changes decoder stuff, and that cant touch lavf at all.

About unrelated issue - please once for all do not mention unrelated issue in unrelated ticket open new ticket for it. Also maud seeking could not affect it at any way, maud seeking only affect maud. So please do not point where issue probably is if you never tested you claims. From now on I will ignore unrelated issue in this ticket.

[Carl Eugen Hoyos]

I suspect da8242e broke an assumption that is approximately buf_size < AVCODEC_MAX_AUDIO_FRAME_SIZE * channels

[Elon Musk]

That is deprecated and not used by this code in any way. Except in ffplay.

[Marton Balint]

Fixed in git master.
