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

Avoir une fonction webtv-like avec la programmation de plusieurs vidéos
3 juin 2013une fonction webtv-like avec la programmation de plusieurs vidéos qu’on pourrait faire lire automatiquement les unes à la suite des autres en boucle (en gros : on constitue une playlist qui se joue toute seule en boucle). le tout avec un code exportable.
Issu du pad de la communauté, proposé en amont de la réunion du 16 mai 2013
