  • ffmpeg converts .flv video to .gif with awful quality [migrated]

    22 février 2013, par Kamil Hismatullin

    I'm converting .flv movie to .gif file with ffmpeg.

    ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000  output.gif

    It works great, but output gif file has a very law quality.

    Any ideas how can I improve quality of converted gif ?

    Output of command :

    $ ffmpeg -i input.flv -ss 00:00:00.000 -pix_fmt rgb24 -r 10 -s 320x240 -t 00:00:10.000  output.gif

  • FFmpeg audio capturing from mic is not working properly

    5 mars 2013, par Thirumalai murugan

    I am using the ffmpeg-20130205-git-c2dd5a1-win64-static version, I am trying to capture the audio and video and send it to the FMS server, I have tried with the following code initially

    ffmpeg -r 25 -f dshow -i video="Logitech HD Pro Webcam C920":audio="Rear Input (SoundMAX Integrated Digital High Definition Audio)" -vcodec libx264 -b:v 600k -b:a 128k -f flv rtmp://127.0.0.1/live/mystream

    it through the following error

    [dshow @ 00000000023f8920] Could not find audio device.
    
video=Logitech HD Pro Webcam C920:audio=SoundMAX Integrated Digital High Definit
    
ion Audio): Input/output error

    Then I modified the code as follows its working fine

    ffmpeg -f dshow -i video="Logitech HD Pro Webcam C920":audio="Rear Input (SoundMAX Integrated" -b:v 600k -acodec libmp3lame -b:a 128k -f flv rtmp://127.0.0.1/live/mystream

    I am unable to understand why its not accepting the full name of the audio driver and if I use the libx264 with the Logitech HD Pro Webcam C920 its not giving the video, video is blank (note : while using the iball c2.0 camera I am able to get the video)

    what is the wrong in my code ? how to publish in the libx264 format ?

  • Overlaying jpg onto Mp4 using -VF

    16 février 2013, par brux

    I am using the following command to overlay a jpg :

    ffmpeg -i in.mp4 -vf "movie=bb.png [movie] ; [in] [movie] overlay=0:0 [out]" -vcodec libx264 -acodec copy out.mp4

    This works as expected with the first file (listed below) but it doesnt work with the second file. There is no error when I try with the second file, rather is creates an unusually large file that would not open :

    In case it is important I am capturing these videos with Android devices. The first mp4 file is created by a Nexus 7, the second (the file which wont overlay the image) is created using a HTC Desire.
