I found dump_format() function (not av_dump_format() ) among ffmpeg source codes : dump_format(ic, 0, is->filename, 0); but i would be pleased if you let me know how can i find a tutorial which shows how can i use the function ? and which header should be included?
BTW i need to extract raw pictures from any video as input which i can achieve this by the below command : *ffmpeg -i input.avi -r 1 –f image2 –vcodec rawvideo* *-pix_fmt yuvj420pImg-%03d.yuv * can you advice how can i achieve this in my c program? (I know that i can run the command by popen() or sytem(), but i think there are some functions that can do this for me too) On Tue, Jul 5, 2011 at 3:25 PM, Clément Bœsch <[email protected]> wrote: > On Tue, Jul 05, 2011 at 02:13:14PM +1000, Amir Rouhi-Rmit wrote: > > Hellow everybody > > How can i get the basic info of any video file which i need by ffmpeg? > the > > information i need i just frame size and length of video. using below > > command seems not standard: > > ffmpeg -i "path of input video" > > Yes, ffprobe is more appropriate. > > > BTW is there any function in ffmpeg to call it in my c program to get my > > information? if yes whats the name and the method of calling the > function? > > > > av_dump_format() > > -- > Clément B. > _______________________________________________ > Libav-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/libav-user > -- Amir H.
