  • FFMPEG options differences between two videos

    9 mars 2016, par Ryan Poolos

    So I’m working with a video build out of pngs. Making a video hasn’t been too hard thanks to ffmpeg however most of the videos I’ve made work great playing forward and are extremely choppy playing backwards.

    Using a program named MPEG Streamclip plus Handbrake I managed to convert my video to one that plays great forward and backward. But now I can’t figure out how to pass in the right options to ffmpeg to replicate this video.

    Using ffprobe I have some outputs of the good and bad video. What options am I missing ?

    Bad Video :

  • Bad video quality and only 3 fps

    25 juillet 2019, par ApplowPi

    There are a few things wrong with the quality of the output file when I run this command.

    arecord -d 0 -r 48000 -c 2 -f S16_LE -t wav -D sysdefault:CARD=tc358743 | avconv -t 0 -i pipe:0 -f v4l2 -i /dev/video0 -c:v libx264 -r 30 -acodec aac -ar 48000 -vcodec flv -strict experimental -y -f flv test.flv

    The audio seems okay at the moment but, if I’m reading it correctly (at the very bottom of the output below), the fps is about 3 and the quality is at 31, which I understand is the worse. This is the output during the process.

    I’m looking to get 30 fps (ideally 60 if possible).

    I’m pretty new to this, any help would be great. Thanks in advance.
