These are just examples of cropping using MKV format tools. I don’t understand why you wrote so much.

Because I thought that you might have unintentionally created anamorphic files.

If so I ask you same questions as LigH
That file plays just fine with my AC-4 decoder.
I'm little bored by exactly same music in all AC-4 samples I have.
Seems like no real content is encoded in AC-4 at all, or I'm out of luck.

I'm glad your fork seems works - you're right - need more AC-4 test files (streams) to be sure.

Hello.
I do not know where to find the configuration file of lav filters. Do you know where it is stored ?
(.ini or .bin or other)

I have the same question for ffdfshow...

LAV Filter settings are stored in the Windows registry:
HKEY_CURRENT_USER\Software\LAV
(or MPC-HC's internal LAV: HKEY_CURRENT_USER\Software\MPC-HC\MPC-HC\Internal Filters )

Could this alternative be implemented as a setting/option in the LAV filter so that the user himself can choose what is best for him? In my opinion, uninterrupted video is more comfortable. Although a several seconds is really a lot.

No, this would be a terrible experience. "I changed the stream but audio was still the wrong language for several seconds", yeah, not wasting my time on that, sorry.

Hi.

Check out the IPinFlowControl interface and the CDynamicOutputPin class.

“The pin can disconnect and reconnect while the filter is still active (paused or running).”

“The pin can negotiate a new media type while the filter is still active, without reconnecting.”

Changing the type is not the problem. The problem is that reading the file is already several seconds ahead for buffering reasons, and to manage to properly go back there needs to be a seek, which isn't going to be perfectly gapless (as seen now).

I try wast your time once more because I have new idea about implementing not all frame decoding (present in FFMpeg) in LAV Video Decoder: if you don't want add that in LAV Video Decoder's configuration window (it's a pity of course) may be you just add one registry key (in MainConcept's and Elecard's Video Decoders such key named Quality) at i.e. HKEY_CURRENT_USER\Software\LAV\Video to MaximumQuality(DWORD=0) as now is, SkipPB(DWORD=1) and SkipP(DWORD=2) frames decoding for power users only? I'm tired to switch between LAV Video Decoder and MPC Video Decoder from MPC-BE for that one aim only i.e. for h265 8K my videocard can't accelerate to watch slideshow with normal audio.

PS. Anybody know why LAV Video Decoder isn't seen in 4T2 Content Analyser (several other Direct Show decoders I tried incl. LAV Audio Decoder are seen well there)?

I've said it before, and I'll say it once again: I will not implement features with the sole purpose of reducing quality from the original video.

If you want to play 8K, you need hardware that is capable of doing so.

I hope you know not all people of the world can let buy videocard can hardware acceleration of 8K h265 4:2:0. I hope freeware LAV Video Decoder not for rich people only.
Moreover only few people can let buy processor (I even don't know what minimum processor is needed - may be AMD Ryzen 9 3900 or Intel Core i9-9980XE i.e. tried Core i7-4770 not enough - stuttering present and with LAV Video Decoder impossible to know what commentator said) can decode all 50fps of only 4K but 4:2:2 h265 20180428-175510_4K ENC 3 RMAD VS LEG.ts (563 MB) https://yadi.sk/d/m0s5ztpj3XnUyw
I'm sure your computer can't do that too.
I don't know why exactly but MainConcept and Elecard many years ago add feature for decoding not all frames of file - same possibility present in FFMpeg so Aleksoid1978 add it in MPC-BE's MPC Video Decoder very quickly - why LAV Video Decoder worse?
I don't know people that think bad about NVIDIA CUVID acceleration of 10bit implemented and CUVID acceleration without "high quality DXVA processing" leading to massive artifacts on nVIDIA videocards on "broken" streams as I asked here.
So I'm sure there will not be any that think bad about one more key in registry
PS. Feature of decoding not all frames can be useful when appear many (at now just few) high resolution streams compressed with i.e. AV1.

What can I say - it's a pity again.

I can't imagine why anybody would want to watch video with only I frames being shown, even the highest ultra-high definition isn't worth that, it's like playing video games at 4 fps.
I'm already pissed when I see sport streams converted from 50p to 25p for the Web...
Regarding 8K, is there even real content (i.e. other than demos made to sell TVs) broadcast only in 8K, that is not simulcast in lower definition on other channels?
