Title: codec frame rate differs from container frame rate
Post by: Jan Gruuthuse on October 07, 2012, 11:45:46 AM

Doing some testing related to copying video/audio content to another container (mts to mp4) related to this thread: Avidemux 2.6 doesnt detect certain interlaced video (http://www.avidemux.org/smf/index.php?topic=11429.0)
ffmpeg produce this warning:

QuoteSeems stream 0 codec frame rate differs from container frame rate: 59.94 (60000/1001) -> 29.97 (60000/2002)

while trying to extract actual frames from video clip

Code Select

ffmpeg -vframes 30 -ss 2.001 -i test.mp4 m4p%d.jpg
test.mp4 is obtained by copying video/audio from .mts container to .mp4 container using mp4v2 muxer (CanonHFM41_1080i_NTSC (http://www.avidemux.org/smf/index.php?topic=11429.msg59898#msg59898))
avidemux seems not to set container frame rate to the current/used/found codec frame rate
