(There is a report about Samsung Galaxy Tab.)

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1340 * cases where a loop happens because the read at the end of the

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1343 * This fix addresses this issue, however it may break in
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1344 * other conditions. Always decode in buffer sizes of powers of 2.

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1347 * If the buffer is short, try filling it up with 0's
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1348 * to meet the user requested buffer_size which

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1350 * hopes to avoid a possible Loki bug with
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1351 * short buffers. If looping (which is the main
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1352 * reason for this), the negative side effect is
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1353 * that it may take longer for the loop to start
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1354 * because it must play dead silence. Or if the decoder
