Description
When playing Indeo 3 videos on the DS, the frame rate is extremely low and falls behind the audio track.
When I last investigated, there were two main culprits:
- The YUV411 conversion performs bilinear interpolation, which is slower than it is without filtering
- The playback code in the BBVS engine performs unnecessary extra copies
- Many engines will always delay for 10 milliseconds without taking the time taken to decode the last frame into account. PR #5740 has a proof of concept solution for this.
This was observed with the Beavis and Butthead in Virtual Stupidity demo.
