#10863 closed Patch - Bug Fix (fixed)

[PATCH] transcode: Tolerate mpeg errors when re-encoding to I-frames around cut points

Reported by: Lawrence Rust <lvr@…> Owned by: beirdo
Priority: minor Milestone: 0.26
Component: MythTV - Mythtranscode Version: Master Head
Severity: medium Keywords: cutlist transcode
Cc: Ticket locked: no

Description

If a recording has a cutlist and is transcoded using that cutlist then if there are MPEG decoding errors around the cut point the process of re-coding to I frames can fail and the whole transcoding fails.

This patch makes the function MPEG2fixup::ConvertToI tolerant to decoding errors and just skips the offending frames.

The bug and patch also apply to fixes/0.2[45]
