Everything is wrong for MPC-BE. Subtitle position and size based on what kind of video is being asked to display.

MPC-HC for 1.85:1

Upload sample video with subs and show MPC-HC settings for subs ?

I think I fixed this, I repeated the same MPC-HC settngs for subtitles. But I noticed another issue: MPC-BE isn't using LAV. How can I force it to always rely on it? Would this be wise?

If you want to use Lav with MPC-BE then go to external filters, search and add the lav filters and configure it like you see in the image and in that order. Do not forget to set it to "prefer" then MPC-BE should use Lav filters.

The Mega version is not recommended for general use. This is written from the link you gave.
Quote:
Mega
...
Important note: The extra filters mentioned above are not installed by default. We also do not recommend using these outdated filters. They are only included for a tiny group of people who have a reason for using them. We strongly recommend to use the default decoders from the pack. Those are better.

Important note: All the extra functionality included in Mega is only useful for a small group of people. It does not provide playback capability for any additional audio or video formats. If you are only interested in playback, then Full version is already enough for you.
I suggest you uninstall K-Lite Mega completely.

PS: First of all, we are looking at problems with the built-in filters and the built-in subtitle renderer. Secondly, we consider the problems with LAV, madVR and system EVR. Everything else is of low priority. We will not waste our time on rare and irrelevant filters.

Yes, but both are based on FFMPEG though so differences are minor at the end of the day. The developers here prefer you use internal decoders which are fully supported in this forum.
Aleksoid looked after the internal decoders inside MPC-HC for a long time before moving to MPC-BE. The internal filters in MPC-BE will cover everything you need and more.

I thought LAV was required because with the default settings the seek bar from MPC-BE was not as smooth as that one from MPC-HC (it seemed any video was heavier), but that was solved after a few changes, such as using or not "Fast seek (on "keyframe") and assigning some keys to fast-forward (one of the 3 possible jumps) and also defining how many seconds to jump (for all 3 speeds), which MPC-HC lacks, BTW.

I used ffdshow audio processor because I don't have an amp at this point and was increasing volume beyond 100%. I own a Sennheiser 598 SR. Most videos are OK, but some are too low. Even so, MPC-BE also has an option to do that, so no ffdshow is required, I discovered this now. I'll get an amp in the future to avoid going beyond 100% and adding +5 or 10 dB, which is not what we should do, not ideal.

A question: if we don't need this codec pack, then besides installing MPC-BE (didn't come with it) or MPC-HC, what other codecs we need to have, say, in a Windows 10 that is recently formatted? Assuming a clean install is not going to play every single audio/video that is out there.

I think all the files I have play out of the box without any codecs/codec packs.

Using exotic codecs for encodes is never a good idea though.

I think I spotted a bug in MPC-BE.

Sometimes when using the seek bar during a playback the video is fuzzy/flickering as you can see from this recording I made from my monitor:

https://www.youtube.com/watch?v=SKyB8qVWKBw

Oddly the whole thing is fixed if we fast-forward or rewind the video again.

Could this be some issue related with my video card? AMD Radeon R7 265 using the latest drivers, Windows 10-64 bit.

And no, this has nothing to do with the video/codec in question, I noticed the same bug yesterday with another file totally unrelated.

If this happens with any video then it's not video-related. Wouldn't I have to upload MPC-BE current settings? A REG file?

I can also take a screenshot from current settings, if necessary.

Please upload the file, I want to analyse it. What happens if you disable Hardware acceleration in options of video decoder for the codec of this video? Still, please upload the file.

This is the affected file:

-

Which I didn't change anything after saw this happening.

The moment from the Youtube video is after 20 minutes. This MKV is a recording from Replay Video Capture, from my browser.

First RVC recorded as MPG, then converted to MP4. Then I added the MP4 to MKVToolnix, removing unwanted parts (split after X minutes).

Where is this option for disabling Hardware acceleration? The video is played with these filters:



What is odd is that I can't reproduce the same bug again. It must be something random that only happens if we use the seek bar, perhaps under specific circumstances?

It can't be specific to this file because I saw the same issue with this other one:

https://pastebin.com/q1uMCcZu

If you compare both MEDIAINFOs you'll see they are totally different.

******
When I tried to open this other file I saw another bug, also from MPC-BE. It's not similar to the 1st Youtube video, but it showed another strange flickering to the sides. When I sent the video to fullscreen this flickering stopped for good.

I was able to do a 2nd recording, and uploaded to Youtube as well:

https://www.youtube.com/watch?v=f6pZ7ulf3mo

LOL. What is going on here? This looks like the graphics from an Atari videogame.

*****
Aaaaaaand the bug has returned. Looks like I spoke too soon:

https://www.youtube.com/watch?v=Xqh-w4JDUFE

Same flickering that goes away if we use the seek bar.

@Perenista: This looks like hardware damage. Maybe you can try another graphics card.

Options -> page: Internal Filters -> tab: Video Decoders -> button: Video Decoder configuration -> uncheck H.264
On toolbar (play pause, ...) there is the "GPU" icon if Hardware decoder is used.

No, same videocodec - H.264

Looks like possible GPU hardware defect -> bad VRAM or perhaps driver bug. Please update to latest driver of your video card. Have you another GPU laying around? It doesn't have to be a "big one", just for testing simple video playback.

All drivers are updated. For the video card and even for Windows, I checked Radeon Software and the Driver Booster app. Also checked Wndows Update.





This is how it was configured. I disabled h264, the GPU icon is now missing from that 1st picture.

If this was due to a bug in my current video card driver then I might have to wait for the next update, and if it's MPC-BE then it could be some incompatibility with this driver and GPU, because this hardware is from 2014. I don't have another GPU at this moment.

I'll keep monitoring and if the bug reappears I'll let you know. I'll also check later with the old options back again. It may have been temporary.

P.S. I just found this link mentioning a similar problem:

https://github.com/clsid2/mpc-hc/issues/835

P.S.2: disabling h264 there made using the seek bar much more faster/responsive. I can now fast-forward or rewind any video way better.

Just upgraded to 1.5.8.6183 and all problematic YT videos are broken again. However the file mpc-be.20210416 which Aleksoid posted works flawlessly so far.
