AV1: invalid stream/video codec not found

[ThreeDeeJay]

I downloaded this video but I'm getting these errors when opening it I tried updating ffmpeg and ffprobe with the latest version, which work when launched directly. So is there another file I have to overwrite to update ffmpeg or does sview have to be recompiled with it? 🤔

sView is dynamically linked to FFmpeg libraries, so that you may replace DLLs within installation folder - like avcodec-58.dll and others.

However, FFmpeg libraries are evolved rapidly and change their ABI (and API) from time to time. You will need putting DLLs of compatible versions (see version prefixes in DLL names).

But then, you end up with using the same FFmpeg release that sView has been built for, and issues could be solved only if they have been backported to an older FFmpeg release (by FFmpeg developers or by you).

Hense, rebuilding sView with newer FFmpeg version might be the most reliable approach to go.

I tried updating [ffmpeg and ffprobe with the latest version, which work when launched directly.

Could you reupload screenshot here or share console input as text? Screenshot within the link is displayed blurry to me, with unreadable text.

I see. Indeed, replacing it with a avcodec-59.dll doesn't work so I guess I'm stuck unless there's an updated avcodec-58.dll, which I don't know where to find since it's usually not included in ffmpeg binary packages😅 As for the ffprobe log, here's the command line from the one built into sView:

Screenshot too cuz why not. EDIT: here's the video file I used.

[gkv311]

I have upgraded sView to FFmpeg 5.1, but this didn't helped much:

[av1 @ 000002a6b2f2ee40] Your platform doesn't suppport hardware accelerated AV1 decoding.
[av1 @ 000002a6b2f2ee40] Failed to get pixel format.
[av1 @ 000002a6b2f2ee40] Missing Sequence Header.
[av1 @ 000002a6b2f2ee40] Missing Sequence Header.
[av1 @ 000002a6b2f2ee40] Missing Sequence Header.

Apparently, one would need building FFmpeg with external library libdav1d (--enable-libdav1d) to have better support of this codec... Though you may now try replacing FFmpeg libraries coming with sView with some alternative build.

I replaced avcodec-59.dll with the one from the latest OBS and now playback works, though I'm getting really poor performance, even though my CPU is maxed out: https://i.imgur.com/7SeO1gg.mp4

PotPlayer playback is pretty smooth even with software decoding https://i.imgur.com/60cy7Vh.mp4 (the recording gets choppy but it actually looks smooth like at the beginning)
