Dave Chapman	4ae85e6886	Revert the addition of the steal_codec_stack function. Replace by accessing the threads structure to grab the codec stack. Maybe a better solution exists. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13349 a1c6a512-1295-4272-9138-f99709370657	2007-05-07 23:54:10 +00:00
Dave Chapman	f4a9dab4d1	Use a separate thread in test_codec, with the same (IRAM) stack as the main codec thread. Add a function to the plugin API to steal the codec thread, which test_codec copies and then restores. Now libmad can be benchmarked. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13347 a1c6a512-1295-4272-9138-f99709370657	2007-05-07 22:30:23 +00:00
Dave Chapman	7cdd0fe6ea	Initial version of a test_codec plugin (viewer). This loads the audio file into the audio buffer and decodes it as fast as it can via a locally implemented version of the codec API. Intended for use when optimising codecs - so isn't built by default. Remember to add it to both plugins/SOURCES and viewers.config to enable it. Currently the codec is run in the main thread which means mpa.codec doesn't work - it requires more stack than is available on the main thread. The solution will be to create a new thread in the plugin which steals the main codec thread's IRAM stack, but that's not done yet. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13345 a1c6a512-1295-4272-9138-f99709370657	2007-05-07 17:23:31 +00:00
