Ok, so I think I have this pinned down to the MPEG4 sniffer. There's a lot of OMAPness within. They have preprocessor removed the default MPEG4 sniffer, and there is an error being thrown within. I still need to check what the output of that method is.
There is a vector list object within the DataSource class which contains one entry for every filetype "sniffer". The first one in the list is the MPEG4 sniffer, followed by the WAV, MP3, OGG, etc. Interesting. I'm going to try gutting the OMAPness from the sniffers related to audio files only and move the video format sniffers to the back of the list. Looking at the code, when a sniffer returns false, it moves onto the next one. I'll need to add some logcat debugging info to the other sniffers to be sure of what's exactly getting called/going on... ...what a mess... -kieran On Wed, Jan 4, 2012 at 1:40 AM, 袁啸宇 <[email protected]> wrote: > Maybe the ALSA implementation was filling in here somehow? > i think it"s impossible.Maybe you delete more files than actually needed. > > I don't really have to include a file parser for every type of file do > I?!?! > no need to do so .
