I noticed that in get_buffer, the just-populated buffer wasn't being returned, but the other one was. But still after fixing this, I heard wrong audio at the beginning of a track, so I took the heavy duty approach and zeroed the buffers out. That means there's a remaining bug to chase, which is merely hidden by the memset()s. 2019-12-23T15:36:50+00:00 Jeff Epler jepler@gmail.com 2019-12-23T15:36:50+00:00 urn:sha1:00628a7dddad07ead8b085e81de90c2dabe71fcc 2019-12-23T15:36:46+00:00 Jeff Epler jepler@gmail.com 2019-12-23T15:36:46+00:00 urn:sha1:02154caf24a73ac706505661d487261e70342116 This enables jeplayer to allocate just one MP3File at startup, rather than have to make repeated large allocations while the application is running. The buffers have to be allocated their theoretical maximum, but that doesn't matter much as all the real-life MP3 files I checked needed that much allocation anyway. 2019-12-16T21:23:41+00:00 Jeff Epler jepler@gmail.com 2019-12-16T21:23:41+00:00 urn:sha1:a63da7a6c0e0537cbefaafb724d722f9587b82a2 2019-12-14T00:31:12+00:00 Jeff Epler jepler@gmail.com 2019-12-13T21:20:48+00:00 urn:sha1:91a1706160aa653cb00c7910b0930df679bcdd21 Apparently sometimes, a proper "frame info" block is not found after a "sync word". Keep looking for one as needed, instead of giving up after one try. This was one reason that the "bartlebeats" mp3s would not play.
