Large corrupted mp3 causes high CPU usage   ________________________________________________________________________ Applicable Environment ________________________________________________________________________ Topic: Large corrupted mp3 causes high CPU usage SDP: 6.4.1 Target: Any supported target ________________________________________________________________________ Recommendation ________________________________________________________________________ There is a scenario where a large mp3 file (over 100MBs) that contained 50% corrupted data caused io-media-generic to take up a majority of the CPU. The cause of this high CPU was the initial average bitrate scan algorithm where the parser is scanning for mp3 headers. The fix is to cap the amount of data for this scan based on a multiple of the maximum mp3 frame size. If you require a patch, please contact QNX for a patch and reference PR77208. ________________________________________________________________________ NOTE: This entry has been validated against the SDP version listed above.
