#12140 closed Patch - Bug Fix (Fixed)

Random segfaults when using VAAPI playback

Reported by: Cédric Schieli <cschieli@…> Owned by: JYA
Priority: blocker Milestone: 0.27.1
Component: MythTV - Video Playback Version: 0.27-fixes
Severity: high Keywords: vaapi crash
Cc: Ticket locked: no


The VAAPI playback is crippled with random segfaults occurring either after some time of playing or at the very first frame. This is due to VideoOutput::CropToDisplay? being applied on the fake frame buffers (VAAPI doesn't give direct access to the decoded frame buffer), ending up in heap space corruption. It was introduced in commit 0a4e3e423d6604252aeb31f849085a00f9f4b2e9 to fix #11358.

The simple attached patch fixes this.
