Description

  • Summary of the bug:

Creating static images from a video works on Centos6-32bit, but not on Centos6-64bit. This issue does not exist in libav-9pre.
The created jpegs look completly destroyed.

  • How to reproduce:
$ wget http://doppelbauer.name/regression.flv
$ ffmpeg -i regression.flv -f image2 -r 1 -vcodec mjpeg -vframes 1000 -qscale 1 %d.jpg

Is this problem also reproducible with current git head?

comment:2 Changed 4 years ago by doublemax

Yes, tested with CentOS6 64bit, ffmpeg-N47885.
Not all images are corrupted, only many.

comment:3 Changed 4 years ago by cehoyos

Please provide the input sample and please provide command line and complete, uncut console output for current git head.

comment:4 Changed 4 years ago by doublemax

Input sample, command line and console output are in the initial bug report.
Here once more:

wget http://doppelbauer.name/regression.flv
ffmpeg -i regression.flv -f image2 -r 1 -vcodec mjpeg -vframes 1000 -qscale 1 %d.jpg

comment:5 Changed 4 years ago by cehoyos

I cannot reproduce the problem but I did not check all 1000 frames;-(

Please provide a failing command line with "-vframes 1" or at least significantly less than 1000, and please provide the console output: It will probably not help, but since I cannot reproduce the problem, it could be useful.

comment:6 Changed 4 years ago by doublemax

Sorry. The first five images are fine, the last 15 images are damaged. This happens only on Centos6 64bit (Centos6 32bit is fine):

ffmpeg -i regression.flv -f image2 -r 1 -vcodec mjpeg -vframes 20 -qscale 1 %d.jpg

Does it work with an output codec different from jpg? (png)
Or even better, could you confirm that the following looks different for you for frames 5 - 19?
Do you still see the "Operation not permitted" error?

To narrow down the reason for the problem, you could either test "./configure && make", "./configure --disable-yasm && make", "./configure --disable-asm && make" and "./configure --disable-optimizations && make" or try with an older version of ffmpeg (assuming there is one that works) and use git bisect to find the change introducing the problem.

I tested with gcc-4.4.6 (vanilla) on x86_64, decoding works fine, jpgs also look fine. Please also post the output of the following command to clarify if this is a decoding (or a jpeg-encoding) issue.

Sorry - I have installed CentOS6 32bit - I can't provide you any tests.
Maybe you want to close this ticket.
Thanks a lot

I am not sure I understand: You cannot run the command line I used and post the output here so we know if this is a decoding or an encoding problem?

Sorry, I misread your post - how do you know it fails on CentOS6 64bit if you only have a 32bit installation?

comment:12 Changed 4 years ago by doublemax

I had both - 32bit and 64bit.
Because of this bug I removed the CentOS 64bit machines.

comment:13 Changed 4 years ago by cehoyos

  • Keywords h264 added
