- bug 916399 - Intermittent test_timeupdate_small_files.html | Test timed out / JW
- cause 1: it looks like there can only be one omx decoder running concurrently. requesting a 2nd one will be halted until the 1st one is released.
- fix: set src attribute to empty string to force release of underlying codec
- cause 2: have to set preload to auto, otherwise loadedmetadata won't be received sometimes
- cause 3: unknow reason for OMXCodec output buffer timeout, playback can't progress
- debugging cause 3, tracing code of OMXCodec
- cause 1: it looks like there can only be one omx decoder running concurrently. requesting a 2nd one will be halted until the 1st one is released.
