  • FFMPEG Audio, video out of sync

    5 mars 2012, par geeknizer

    I'm creating Video using FFMPEG from pngs. The problem is on creating the video, and combining with video, its never in sync.

    Create video :

    ffmpeg -i /home/ubuntu/pngs/* -vcodec libvpx -r 25 -b 1024k -y video.avi

    generate audio

    ffmpeg -y -f s16le -ar 44100 -ac 2 -i wav_file.wav -acodec libvorbis video.avi

    these snapshots were taken at 25fps from a video. Audio is also extracted from same source.

  • How to quantify and compare video quality

    24 mars 2015, par user940154

    I have a set of uncompressed videos in YUV format.

    I have obtained several derived copies in various formats and resolutions from these yuv files using FFmpeg transcoding. (YUVs ----> X Derived Copies)

    What I have also done is, transcode the yuv’s into same resolution AVIs, and now obtained the same set of derived (transcoded) videos treating the AVIs as master. (AVIs ----> X Derived Copies)

    Now I wish to compare the quality of transcoded videos, when derived from AVIs to those derived from YUVs.

    Is there any way for me to do this using FFmpeg. How ? If not, can you please suggest some good open source software to do this.

    Thanks
