Revision e7a28149
Added by Andreas Smas about 5 years ago

Rework how Movian chooses strategy when opening files

Generally, it works as follows:

If it knows it will be an audio file it will probe with very small max buffer

If it doesn't not really know the file type yet or if it knows is a video file
it will check if the file is seekable, if so it will use a full probe, otherwise
a somewhat smaller buffer.

Recently this was changed so we always did a small probe for video files which
just broke a lot of things

Change included in version 5.0.26

History

#1 Updated by Andreas Smas about 5 years ago

I need a logfile, see logging and preferably a sample to test with, see Guideline_for_creating_issues for how to slice files into usable samples

#2 Updated by Andreas Smas about 5 years ago

  • Status changed from New to Need feedback

#4 Updated by Andreas Smas about 5 years ago

  • Priority changed from Normal to High
  • Target version set to 5.2

#5 Updated by Rob Koni about 5 years ago

I tested this file too, as I'm curious where this leads to. I have had the "cpu too slow errors" as well in the past on other files.
Your error is confirmed, I see the message as well, video is very stuttery.

Maybe it's because of the 5.1 to stereo conversion?

#6 Updated by Rob Koni about 5 years ago

I played the same file in 4.9.430 and it works fine there, see log.

Strange thing is that 4.9 seems a little bit faster to me than 5.0+ but I don't know why...
