jump to a specific frame

[andreahmed]

Is it possible to jump to a specific frame ?

it is not easy especially when the frame is not a key frame. you should jump forward and decode.
unfortunately vlc do not provide such functions so you should write by yourself.

Thanks for your reply.

Is it possible to use libvlc_media_player_get_length and libvlc_media_player_get_fps to get the number of frames and then use set_pos to jump to a specific frame?

it's absolutely possible,but difficult. it depends on video format a lot.
ffmpeg provides a function seek by frame ( av_seek_frame),but i have not tried;
in vlc,you can calculate the specific frame's time stamp and set_time to the nearest key frame,then get next frame until the time stamp is the nearest to your expectation
