BeebEm video capture problem with playback

Post by fwibbler » Sat Apr 07, 2018 6:21 pm

Hi,

I've been having this same problem with Beebem for some time now.

Whenever I try to playback videos captured with Beebem, only the sound plays, i get no video.
My player of choice is Media Player Classic Home cinema (latest version), but even if I try to load the video into TMPEG Video encoder 6 it still doesnt show video.

I'm guessing I'm missing the right video decoder, but what decoder is it?
Anyone have any thoughts?
Many thanks.

I presume you have a Win10 computer. This is a current incompatibility with BeebEm. There are numerous branches and backlogged fixes from various people that have not yet been centralised into an "official" new release of that emulator.

As far as I recall, someone here has a working fix for this (maybe in their own code repository) but I don't recall if a binary was compiled and distributed for this.

Hi,
Thanks for that.
I am using windows 10 (forgot to mention that!)
If i try it with windows 7 then i can at least load it into TMPEG and recode it.
Cheers!

I'm currently maintaining BeebEm. The latest version is v4.15 beta 1, available here, which may fix the video capture issue. Please give it a try and let us know if it works for you.

Have you tried VirtualDub (it's an editor really, but also playes back), I use it to rescale my videos before posting on youtube as they need to be at least 720p to playback at 50Hz?

The problem with VDub (good though it is) is that it uses only the encoders/decoders installed on the system. Same as MPC does for playback.
TMPEG uses the stsyem codecs and has some of its own.

Anyway, ive got it to work as far as I need it to with Windows 7.

I'll have a look at the new Beta version with Windows 10 when i get some spare time (heavens knows when that will be :( )

Thnks for the help

What I did for b2 to help with this was add a separate option for outputting YouTube-friendly hidef videos. It's nothing clever: it just outputs a video that's twice the width and height, so instead of 720x576x50Hz (which YouTube scales to nastly 25Hz 480p or something) you get 1440x1152x50Hz (which YouTube scales to 50Hz 1080p).

You can see an example here: https://www.youtube.com/watch?v=TYb7XjnMsaA
