#4076 new defect

Poor performance when using unsharp filter on multiple outputs

Description

Summary of the bug: When using FFmpeg to encode two seperate video outputs from a single video source, performance drops significantly when using the "unsharp" video filter on BOTH outputs. If only used on one of the two outputs, performance appears normal.

This is a problem particularly when using a DirectShow source, since the real-time buffer will almost immediately fill and cause dropped frames/out of sync audio making it impossible to stream from a live video source.

First sample, showing the issue, notice the poor fps (input framerate is 59.94 fps) and real-time buffer errors causing frame drops, CPU usage is 40% or lower.

When using the "unsharp" filter on only one of the single outputs, performance is as expected, encoding in real-time at the input framerate without any real-time buffer errors:

I tested the issue using file input (instead of a DirectShow source) and the same issue seems to be present. As expected, there are no "real-time buffer errors" - but performance is still drastically reduced.

comment:1 Changed 3 years ago by cehoyos

  • Keywords unsharp added
  • Version changed from unspecified to git-master

Can you reproduce the issue with file input, without audio and using -vcodec mpeg4?
If yes, please provide such a command line so I can try to reproduce.

comment:2 Changed 3 years ago by speaker219

Yep, same issue when using a file as input with -vcodec mpeg4, notice the poor performance on the first run (using unsharp filter on both outputs):

~60 fps when using unsharp filter on both outputs, ~94 fps when only using on one. CPU usage is well below 50% on both runs.

Using unsharp on both:

cmd>ffmpeg -t 60 -i "testfile.mkv" -vcodec mpeg4 -vf "unsharp=5:5:0.2:5:5:0.0" -maxrate 1600k -bufsize 2000k -s 960x540 -pix_fmt yuv420p -an sd.mp4 -vcodec mpeg4 -vf "unsharp=5:5:0.2:5:5:0.0,fps=fps=30" -maxrate 900k -bufsize 2000k -s 854x480 -pix_fmt yuv420p -an sd.mp4

comment:3 Changed 3 years ago by rogerdpack

as a side note, high cpu shouldn't cause things to get out of sync since it's dropping frames but then passing laster frames through with the appropriate (later) timestamps...should it? Does it get more and more out of sync over time?

Note: See TracTickets for help on using tickets.
