Ticket #1849 (new defect)
AMR NB NODATA header changes following data
|Reported by:||krisha||Owned by:|

Summary of the bug:
If you put 0x7C as header (MODE = NO_DATA) the following frames behaves weird (only header, no data bytes). In Audacity with FFmpeg v0.6.2 you hear a 'knock' and the following signal wave behaves different on zooming levels and (this might be also GUI audacity bug). In VLC 2.0.3 this 'knock' is also heard.
I attached a sample file with silence and a NO_DATA frame at file offset 0x166.
I'm not sure which versions of FFmpeg are affected, but I assume all that use the codec from libavcodec/amrnbdec.c
