#868: [8350] breaks mpeg2 decoding during frame advance
--------------------------------+-------------------------------------------
Reporter: bjm <bjm at lvcm.com> | Owner: danielk
Type: defect | Status: new
Priority: minor | Milestone: 0.19
Component: mythtv | Version: head
Severity: medium |
--------------------------------+-------------------------------------------
To reproduce:
- Install SVN [8350] or later
- Record a file, or view a live buffer, with an ivtv hardward encoder
card.
- Begin playback and find a scene with some continous motion.
- Press Pause.
- Press ">" to advance one frame at a time.
The first advance appears to jump back several frames. Keypresses after
that
apply fragments of images and decode errors to the initial image. The
frontend prints messages like this:
{{{

}}}
Mpeg4 software encoded files advance one frame at a time properly as do
mpeg2 files played back with mythfrontend version [8349] or earlier.
