console spamming when decoding a h264 / mp4 stream

Description

Consider:

ffplay http://video.ted.com/talk/podcast/2013/None/AndrewMcAfee_2013-480p.mp4

This video plays fine at first, but about 130 seconds in it starts spamming these messages:

AVC: nal size 0 nan fd=   2 aq=   46KB vq=    0KB sq=    0B f=0/0

This is with latest git (fa125c5e82fce4). A user reported that a 2 week old Libav actually caused failed with an assertion on this.

No, I won't follow the cehoyos ritual, don't even ask. It's easily reproducible.

Same problem reproducible with 1.2, dunno if regression.

Which application plays the file?

comment:3 by gjdfgh, 13 years ago

Unknown, could as well be a broken file.

the link is from ​http://www.ted.com/talks/andrew_mcafee_what_will_future_jobs_look_like.html

comment:4 by Carl Eugen Hoyos, 13 years ago

The question actually meant Clément who set the ticket to reproduced, but if you assume a broken file then what problem exactly are you reporting?

More generally, the console output is of course only the necessary part of a bug report, it is very often not sufficient, but (unfortunately) it is typically difficult to define how a sufficient report looks like. How do you expect that you report all facts that are needed for a sufficiently detailed report if you already fail at the necessary parts?

Replying to cehoyos:

The flash player on ted doesn't seem to have a trouble with it, but I can't tell if that's because another quality is picked. Also, it's likely streamed differently than "file-based" (likely HLS or similar since it deals with bitrate changes).

Summary: can't decode some mp4/h264 streams → console spamming when decoding a h264 / mp4 stream

Well broken playback is the issue... not the console spamming (and that doesn't sound like a minor issue)

Please elaborate!
(I was unable to reproduce / decoding works - perfectly - fine here, of course it is very possible that I am wrong but without any explanation this is extremely difficult to guess / understand.)

And please note that I doubt your command line allows to reproduce a decoding problem...

The video is not supposed to be stalled like it is currently (frame decoding doesn't work so last pic is kept); see ​http://www.ted.com/talks/andrew_mcafee_what_will_future_jobs_look_like.html (you can download the low res to compare, IIRC this version works)

And please note that I doubt your command line allows to reproduce a decoding problem...

Fixed.

That brings me back to my original question:
Which application does not stall?
(Before you answer: Note that afaict most frames in the sample only consist of "0" and "1" making decoding extra difficult imo if we do not assume 1bit ppm or bmp.)

Or in other words: To the best of my knowledge the sample is broken and FFmpeg decodes it *extremely* well (spamming the console).

(It is still not unlikely that I am completely wrong, that the sample can be decoded much better / not stalled but that would imo need at least some indication.)

Replying to ubitux:

% ☭ ./ffplay -ss 130 /tmp/AndrewMcAfee_2013-480p.mp4

So this is only reproducible with ffplay?
ffplay works fine here for the sample (there may be minor desync but it catches up quickly and I wonder if it is always reproducible, sorry that I find it a bit extreme to also test this thoroughly for such a bad report.)

It seems totem/gstreamer is able to, according to the user.

(Before you answer: Note that afaict most frames in the sample only consist of "0" and "1" making decoding extra difficult imo if we do not assume 1bit ppm or bmp.)

Are you sure you're not confused with some data in the (large) MP4 header?

Also, the frames around this timestamp have very low differences, so it's not surprising to have small data frames.

totem plays the sample here exactly like ffplay and ffmpeg.
(Rereading the original post: Is it possible that this was just "wrong bug tracker"?)

(Before you answer: Note that afaict most frames in the sample only consist of "0" and "1" making decoding extra difficult imo if we do not assume 1bit ppm or bmp.)

I just realize that this can be misunderstood: I meant h264 video packets that consist only of 0x00 and 0x01 are most likely invalid;-)

Are you sure you're not confused with some data in the (large) MP4 header?

Certainly possible, but is the large header really supposed to be in the middle of the file?

Also, the frames around this timestamp have very low differences, so it's not surprising to have small data frames.

This is of course also possible but I would have expected those small data frames to be >0 in size (many packets in the broken part of the file have size 0) and not containing only 0x00 and 0x01.

Well you certainly seem to have trouble to reproduce this problem. Even worse, you're not even telling us with what ffmpeg git version it appears to work, and you're not pasting full uncut console output.

Either way, I hope you understand that this is not my problem, but yours. If you don't want users to report bugs, maybe disallow public registration and posting?

Cannot reproduce
i seem to have had the file on my disk already so i assume i could reproduce this previously
now i cant neither with the file i have nor the URL
can someone confirm that this is fixed ?
(not reproduce == no spam no artifacts)

comment:20 by gjdfgh, 12 years ago

Can't reproduce anymore either.

I suggest closing with WORKSFORME.
