Title: Bug in decoding IMA ADPCM
Post by: Pushman on February 04, 2013, 01:17:58 PM
Hi everybody
When I open *.mov files from camera, everything is OK. But decoded audio (IMA ADPCM) is destroyed. In older version everything is OK. Please for help.
Sorry for my English.

The described problem (http://www.avidemux.org/smf/index.php/topic,11634.0.html) shouldn't occur in the nightly build (http://avidemux.org/nightly).

Confirmed (using ADM 2.6 r8447):

MOV (H.264/IMA-ADPCM) --> MP4v2 (Copy/AAC-faac):  audio is stuttering (sounds like a machine gun).
MOV (H.264/IMA-ADPCM) --> MP4v2 (x.264/AAC-faac):  audio is stuttering (sounds like a machine gun).

The developer might have a look at it.

Thanks a lot. Seems to work, tested with r8469:

MOV (H.264/IMA-ADPCM) --> MP4v2 (Copy/AAC-faac): okay
