Problems with frame rate on video conversion using ffmpeg with libx264
29 mai 2013, par Lars SchroeterI have problems with transcoding some videos. I ran the most simple ffmpeg command and it takes very long time and the output file is about 10 times bigger. If I provide the frame rate parameter -r it works well (small file, fast transcoding). What is the problem and how can I solve it ? I don't want to set a fixed frame rate because I guess it's better to leave it the same as source, isn't it ?.
Maybe the problem is something else, because I found many examples in web where the -r option isn't used. Also transcoding to a different format or with a different source works well without -r option (I tried with ffmpeg 0.7.15 and also 1.2.1). The videos are provided by the users of my website and automatically converted to be suitable for the web. So I need the most general command for automatic conversion.
In the following ffmpeg output you will find this two suspicious messages :
- Frame rate very high for a muxer not effciciently supporting it. Please consider specifiying a lower framerate, a different muxer or -vsync 2
- MB rate (36000000) > level limit (983040)
The ffmpeg command and output (without -r option) :
ffmpeg -i '/tmp/standort_aquarium.mp4' -vcodec libx264 output.mp4
