ffmpeg crashing on some .mkv or other input file
Posted: Tue Jun 05, 2012 6:55 amSo I tried searching and did not find anything that appeared to be related to this
I was experiencing a crash of ffmpeg on my windows xp 32bit box using the FFmpeg git-9c27f29 32-bit Static (2012-05-27) build from http://ffmpeg.zeranoe.com/builds/
The crash was occurring when I tried to change the start time in the flash player from anything other than 0:00
When I looked up the -ss command in the ffmpeg documentation it states that it could be used before -i (input) or after, so I moved it to after the -i (see below)
This does make it take a little bit longer to seek as it decodes the input till it finds the time instead of just trying to use the files time table, however it tends to be more reliable and accurate according to the documentation and my experience so far
I also noticed that they changed the way -b is used, now it should be -b:v for video bitrate and -b:a for audio bitrate
i have updated my transcoding command like so
