[FFmpeg-user] MPEG TS from DVB-T to ProRes 422 - Trouble with sound.

[Stan Defawes]

in fact the problem seems to have difficulty to synchronize audio and video

this alert is coming a lot of time when encoding : 

error, audio timestamps difference is too big, cannot compensate a/v sync

and the result is no audio in the file output.

Is the some parameters to force synchro when encoding ? like -async or something like that ?
