By looking at the media info

"Format settings, ReFrames: 10 frames"

The 10 frames is too high for Showtime.

#3 Updated by Andreas Smas almost 9 years ago

  • Target version changed from 3.3 to 3.4

#4 Updated by Andreas Smas over 8 years ago

  • Status changed from New to Accepted

#5 Updated by Andreas Smas over 8 years ago

  • Status changed from Accepted to Rejected

Reframes too high yes

#6 Updated by Philipp Grosswiler over 8 years ago

I am sorry, but I don't get it. What does it mean, reframes too high? How does that solve my problem? I can play the sample video fine in MPlayer, VLC and every other video player just not with Showtime. So clearly there is a problem within Showtime?

#7 Updated by Andreas Smas over 8 years ago

No, it's a problem with the h264 decoder available on the ps3. It just does not support this video file.

Showtime will play the content just fine on Linux or OSX.

#8 Updated by Philipp Grosswiler over 8 years ago

Thank you for clarifying this issue.

Would it be possible to play the movie if Showtime would use software decoding of H.264 using ffmpeg like it does on Linux?

#9 Updated by Andreas Smas over 8 years ago

It woudl be possible but is almost 100% certain to be too slow. the PowerPC CPU in the PS3 implement some instructions that's crucial for h264 in a very slow fashion.
