Description

Summary of the bug:

At a seemingly random interval ffmpeg will freeze (become non-responsive and stop writing output to the console) at 12% CPU and constant RAM when -vf "scale... is specified. Process must be killed to continue.

How to reproduce:

% ffmpeg -c:v h264_qsv -i h264file.mkv -vf "scale=min(iw\,1280):trunc(ow/dar/2)*2:flags=fast_bilinear" -codec:v:0 h264_qsv -codec:a:0 aac -strict experimental -ac 6 -ab 128000 -af "aresample=48000:async=1" -y "qsvout.mp4"

Priority: normal → important

Please provide a simplified command line that allows to reproduce the issue together with the complete, uncut console output to make this a valid ticket and please provide a backtrace from the hanging process.

Added two attachments. One which shows initial progress (transcoding is working), then when it locks (ffmpeg spins at 13% progress stops changing).

I don't know what a backtrace is or how I might obtain one.

Hi babgvant!
Is it possible to get source stream by some way?
What the system (CPU model, Linux version full kernel version) uses? Was the Linux kernel patched as original Intel documentation does require?

Hello,

The source stream doesn't seem to matter. Every source I've tried has reproduced this issue. I can try to find/create a smaller file (the ones I have been using are very large) if you want.

I have tested on two PCs, both running Windows (10/8.1) with the latest drivers from Intel for each (i7-4770k/i7-3770s). Native QS decode/encode/VPP works in both systems using another MSDK enabled application.

Thanks

I have reproduced the issue, thanks.

Hi, I have the same problem without the need of any rescaling. It freeze the same way, in the first 10 minutes on each source.

Please test current FFmpeg git head, provide a simplified command line that allows to reproduce the issue together with the complete, uncut console output and add a backtrace.

Reproduced using db44b599805fdd96940cf2e5a336f872648bbda1 and the unsharp filter.

Version 1.17 of the MFX library was used, and the latest display drivers.

Command was

ffmpeg -i in.mp4 -c:v h264_qsv -vf unsharp=lx=7:ly=7:la=0.56:cx=7:cy=7:ca=0.28 -b:v 2M -preset:v veryfast -y out.mp4

Uncut console output

I just reproduced this on Linux.

Replying to cehoyos:

I'm reasonably sure that I'm hitting this same issue described here. I ​posted a writeup including the details of the environment as well as the CLI output from when it hangs/freezes, if anyone is interested in looking at this in more detail I'm happy to provide more output and or testing (to a reasonable extent)...
