-itsoffset with overlay filter buffer queue overflow

[Tim Willison]

Summary of the bug:
When attempting to overlay a video on another video, use of -itsoffset to delay the start of the overlay results in buffer queue overflow errors and dropped frames. Video is unusable.

I have tried with libx264 encoded mp4 files, as well as mpg and mov files and the problem is recreated every time.

Use of -itsoffset without the overlay filter seems to work as expected.

How to reproduce:

ffmpeg -i greenscreen2.mp4 -itsoffset 2 -i hero.mp4 -filter_complex '[1:0]scale=iw/2:ih/2[out];[0:0][out]overlay' -report -y mytest.mp4

Is this only reproducible using external libraries (libx264, libfaac) or also with native encoders?

Commit b0012de is not the source of the bug, it only un-hide it.

That was fast;-)

Commit b0012de is not the source of the bug, it only un-hide it.

Is it possible to reproduce the problem with a released version?
(Will I have to cherry-pick the commit?)

Replying to cehoyos:

I was already on it yesterday evening.

Is it possible to reproduce the problem with a released version?
(Will I have to cherry-pick the commit?)

I do not think so. The line necessary to fix the problem was lost when the "evil plan" was merged, probably during commit a05a44e. IIRC, no release was made after that.

[Carl Eugen Hoyos]

Fixed by Nicolas.

[Amit Agarwal]

This doesn't work for me at Mac with version 2.2.1

[Carl Eugen Hoyos]

Works fine here.

[Amit Agarwal]

But it didn't work for me. It would be great if the underlying problem can be fixed in this case. Posting logs in case it helps.

Here is the command I executed:
ffmpeg -i .Files/1szqpq/hjmuqD/creation/overlaid-video.mp4 -itsoffset 22.952 -i .Files/1szqpq/hjmuqD/creation/07eda82db409f6c212ffa829287d9c0d_clip.webm -filter_complex "overlay=x='if(gte(t,34.28),NAN,0)':y=0" -y .Files/1szqpq/hjmuqD/creation/overlaid-video-2.mp4

Replying to lifeamit:

But it didn't work for me.

You failed to provide any relevant information.

Please do not edit keywords, if your issue is not a regression, open a new ticket instead of reopening this one (that was a regression).

Is it reproducible with -an? If yes, please use it to simplify the command.
Is it reproducible with an internal encoder like -vcodec mpeg4? If yes, please use it, it makes reproducing issues significantly easier.
Is the problem only reproducible if a formula is used with the overlay filter? If not, please remove it.
Is your problem reproducible with b0012de4?

[Amit Agarwal]

It is not reproducible with -an but then the final video looses audio which I don't want.
It is reproducible with -vcodec mpeg4
It is reproducible only when I use overlay filter (that too with -itoffset
What is b0012de4 and how to use it ?

[Carl Eugen Hoyos]

Please open a new ticket for your apparently unrelated problem (this regression was reproducible with -an).

Hello

I have similar problem using overlay and trim together:

I have a video that have a logo that should be delogoed and also the video have some boxes popping up in just 15 seconds of the file and I want to remove that too.

As examples of overlay filter in online ffmpeg docs, I've used this command that throws me some Buffer queue overflow, dropping. messages and the video freezes after 3rd second to when the trim has been occured: (to have informations I appended -report)

$ ./ffmpeg -i ~/Videos/SJ9VRF.mp4 -vf '[in]split[mainlogo][boxlogo];[mainlogo]delogo=x=95:y=35:w=80:h=20[maindelogo];[boxlogo]trim=start=60:end=75,delogo=300:30:100:20:show=1[boxdelogo];[maindelogo][boxdelogo]overlay=eof_action=pass[out]' -report -y ~/Videos/SJ9VRF-edited.avi

The output is:
