Comment (by MasterQuestionable):
͏ The log probably wouldn't be of much use.
͏ I guess it's mostly the cause mentioned by Balling:
͏ Dependent frames unavailable for the current frame's decoding.
͏ (that utilizes Inter-frame compression: a frame may refer arbitrary
other frames)
͏ .
͏ Thus it may only continue display at that doesn't depend on previous
missing frames.
͏ (or presenting half-decoded garbage meanwhile)
͏ The problem could probably be mitigated by setting "-noaccurate_seek"
(input)?
͏ Or certain fix on the server-side that delivers the stream.
͏ ----
͏ Off-Topic:
͏ Interesting fact:
͏ The [ https://i.imgur.com/H7X30ua.png ] here can receive 90%+ size
reduction via WebP Lossless:
͏ `ffmpeg -y -v debug -hide_banner -nostdin -nostats -i "H7X30ua.png"
-lossless 1 -q 100 -compression_level 6 "H7X30ua.webp"`
͏ (188,343 B vs. 13,240 B)
