VLC reports mp4a with AAC extension SBR+PS
Very odd, seems mixed audio (channels or streams) with different properties.
Don't know what the developers make of this?
Mediainfo on vlc different on avidemux
On vlc frame rate is 25 f/s and on avidemux is 50f/s
Audio is 48000 and on avidemux is shown 24000
hi
this is another test file in .TS

Audio in both samples plays fine for me in Avidemux. I wonder if the audio track is mislabled in the container, Avidemux seems to get it right.
i checked with some version of avidemux but audio was not correct
different information on vlc and avidemux !!!
What do you mean by "some version"? It should be the latest git master.
The info differs, but it is likely that Avidemux gets it right (at least it plays the audio in the provided samples fine according to my testing).
i have used latest version but same result .
i have tested by 3 pcs separately.
avidemux version is 2.7.0 and 2.7.0_r171114_win64
