Getting file info with ffmpeg, object file recognized as Audio ?
27 octobre 2011, par cplI'm testing a C++ program that should iterate in a directory and find all multimedia files. I used an iteration routine, and for every file I tried using the libav functions to open the file, such as av_find_stream_info in order to find stream info. It works fine for multimedia files, such as video and images, but the problem is that it recognizes some files as audio or video, for example it sees an audio stream inside a .o file! I also tried to use av_read_frame and it worked fine, without errors! I would like to avoid filtering by extension, is there any other solution to find "playable" files?
Thanks

how can I get/compute the correct timestamp of the audio?

how to create or extract a silent mp3 from a video file using ffmpeg or mencoder ? [migrated]
25 octobre 2011, par mirswithI am looking to create an mp3 of silence that is the same duration as the input video file using either ffmpeg or mencoder.
Using ffmpeg I have tried this:
ffmpeg -y -i in.avi -ab 8k -ac 1 -vol 0 -acodec libmp3lame out.mp3Which works great if the video has an audio track but fails miserably if it does not.
Any ideas?
Thanks!
