  • How to find the presentation time stamp of a given frame number for FFMPEG decoding ?

    21 août 2017, par Deepankar Arya

    I am using the C APIs of ffmpeg for some video processing. My aim is to extract the screen shot of a given frame number.

I assume that I will have to goto to the most recent I frame for the given frame(using the AVSEEK_FLAG_BACKWARD flag) and read onwards untill I meet the required frame. For that I need to give a seek time stamp to the av_seek_frame function. My main issue is that given a frame number, how do I find an associated presentation time stamp to seek to ?

    I've seen this answer :

    But before I try to find out what changing the FastCGI protocol is and how to do it : is there a way in the code to avoid this ?
