This output is from  2f56a97f which merged the bad commit. 32-bit Ubuntu Natty. Current git master (g3b5ddf0) has the same behavior.

which buffer size works for you ?

[llogan]

65536 seems to work with mic input. Anything less results in:

[matroska @ 0x2c40a80] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 128 >= 128
av_interleaved_write_frame(): Invalid argument
