No valid source found for MPEG-1 video

Post by questiontime »

Description of problem or question:
I'm trying to convert an old .mpg video to a modern format. It plays fine in VLC and Quicktime Player.

VLC identifies the video as "MPEG-1/2 Video (mpgv)" and the audio as "MPEG Audio layer 1/2 (mpga)".
Quicktime identifies the video as "MPEG-1 Video" and the audio as "MPEG Layer 2"



Steps to reproduce the problem (If Applicable):
Open Handbrake.
Select video in file chooser.
Result: "No Valid Source Found".

If a batch of files is selected, it loads all the others and ignores (apparently) any MPEG-1.



HandBrake version (e.g., 1.0.0):
1.2.0


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
MacOS Mojave 10.14.3

That did it! Thanks.

I was running "Check for Updates..." from the Handbrake menu, but it just showed a "Checking for Updates..." progress bar, finished, and disappeared, leading me to believe it was current. Manually downloading 1.2.2 did the trick.

Yes, unfortunately the built-in upgrader is broken in 1.2.0 and 1.2.1.
