PS3 Movian - Slow with a lot of video file in same folder

[RKJ]

Hi everyone. I have been using movian for a few years now, with different cfw and different versions of movian and this bug is always present.

I have an ntfs external hard drive with a collection of video files in different formats and encodings.

Sorry if I won't be very "technical" in describing the problem.

Some video files with "easy" encodings never slow down. They seem easy to handle for the ps3. They play well even if there are many placed in the same folder.

Some "difficult" encoded video files seem to slow down under certain conditions.
I'm not talking about formats that are impossible to reproduce like h265, but about certain .avi files with high mpg4 compression. These are videos that you notice are at the limit of the system's capabilities but are playable.

If these "heavy / difficult" files are placed in many in the same folder, their playback slows down and jerks. Maybe the first 10 minutes of playback are ok, then more and more slowdowns accumulate.

If, on the other hand, these files in "heavy / difficult" format are each placed in its own "ad hoc" folder, they are played correctly by movian.

Another event that creates slowdowns is "browsing" a folder with many "difficult" video files, the more folders with "difficult" files I navigate inside movian, the more likely it is that movian will become slow even with easy files. In this case, closing movian, reopening it and navigating directly to the video file I want, solves the problem (if the video file is "easy" or "difficult but in a folder by itself").

Even an "easy" file played from the same folder where I have other "difficult" files tends to slow down.

The last person that I know that was working on MOVIAN is @deank.
He haven't been active on PS3 scene since the last MOVIAN update on June of last year.

It's been a few years since I was last using Movian to watch video files but a couple of tips that I can give are this.

1. If a video file is compatible but over-sized (2GB+) it may tend to have a lot of lag in terms of processing/rendering

2. I'm not sure if it has to do with all of the files being together or maybe it has to do with my 1st tip involving each individual file

3. I found myself using mkv2vob quite often when converting Matroska videos to a compatible format.

I can't remember what video format I converted to (it was either MP4, AVI, F4V or DIVX) but there are quite a few

As for sound, I think it was the OGG format that I used to keep consistent with quality while massively reducing the audio file size

Altogether as one container, I seem to recall it reducing 4GB-8GB files into 2GB (with quality intact + better buffers)

Then again, I only used these methods to watch AOT S1 from my PS3 when I didn't have a BR player to watch from USB.

I have to make a clarification, I was not very precise in the use of the word "heavy file".
I was not referring in particular to the space they occupy, but to a sort of "heaviness / difficulty" in being reproduced.

Generally to give me more problems are .avi with mpeg 4 encoding with a size between 600MB and 1 Giga approximately.

Unfortunately I am not very expert in coding, I am bringing you some unscientific descriptions of the bug. For example, I noticed the mpg4 encoding from the movian popup on the details of the file being played.

Most even large .mkv files almost always work fine. When they have slowdowns I resolve by moving them to other folder locations (which is the same method I make small files with difficult encodings work well).

In a completely empirical way, without understanding why it happens, I noticed that by placing the files that slow down in certain folders they are reproduced correctly in my external USB Ntfs hard drive:

-A folder with n video files "with easy-to-play codecs" --> ALL OK

-A folder with n video files "with easy-to-play codecs" and at least one hard-to-play encoded file --> all files inside the folder tend to slow down

-A folder with only one file inside --> Always ALL OK

-If I browse for too long between files on the hard disk before choosing the video to play, movian slows down

I looked at the info movian popup for some files:

Some critical files:

1)Source: AVI (Audio Video Interleaved)
Video Codec: MPEG4 Simple Profile, 544x224
Audio Codec: MP3, 44100 Hz,stereo

2)Source: AVI (Audio Video Interleaved)
Video Codec: MPEG4, 640x368
Audio Codec: AC3, 48000 Hz, stereo

3)Source: AVI (Audio Video Interleaved)
Video Codec: MPEG4, 512x384
Audio Codec: MP3, 48000 Hz, stereo

An example of a file that works well for many in the same folder:

1)Source: AVI (Audio Video Interleaved)
Video Codec: MPEG4 Advances Simple Profile, 512x384
Audio Codec: MP3, 48000 Hz, stereo


Another thing I noticed is that the "critical" files slow down even more evidently when there are "intense" music when the audio has acute phases ..
