  • ffmpeg conversion skips audio

    10 mars 2012, par user504879

    While converting a video to mp4 format using ffmpeg the audio gets skipped because of which the audio goes out of sync with the Video.

    One can have a look at the following Video :
    https://vialogues.com/vialogues/play/486

    I am using the following options for conversion

    /usr/local/bin/ffmpeg -y -i $inputfile -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -level 41 -bufsize 20000k -maxrate 25000k -g 250 -r 20 -s 480x270 -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +dct8x8+bpyramid -me_method umh -subq 7 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq 'blurCplx^(1-qComp)' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6 -crf 25 -deblockalpha 0 -vpre medium -deblockbeta 0 $outputfile

  • ffmpeg doesn't generate video from images

    6 juillet 2017, par mans

    I am trying to create a video from jpeg images using ffmpeg. The generated video should be in x264 or x265 format.

    I have a directory with 36 images . Each image size is around 60Mpixel. They are names as follow :

    • frame00000.jpg
    • frame00001.jps
    • frame00002.jpg
    • ....
    • frame00035.jpg

    I read documentation and several posts in SO and I came to write a batch file to call ffmpeg as follow :

     ffmpeg.exe -r 1/5 -start_number 0 -i %1\frame%%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4

    when I run this command, I am getting this output from the ffmpeg, which is strange :

    C:\Users\m\Desktop\ffmpeg-20170702-c885356-win64-static\bin>ffmpeg.exe -r 1/5 -start_number 0 -i "C:\Resized"\frame%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4

    As can be seen :

    • it reported :

    deprecated pixel format used, make sure you did set range correctly

    what that means ?

    • It is trying to process more than 36 frames, when we only have 36 frames.
    • Until frame 25, size is zero and bitrate is N/A and after frame 25, size became none zero.
    • It runs for several hundred images and then stops, but I can not play video.
    • After frame 47, FPS became zero.
    • I can not play back the output video.

    How can I fix these problems and create a video from these frames ?

    Edit1

    After getting some reply, I noted that h264 can not support the final resolution so I converted to use VP9 and I am using this command :

    ffmpeg -i %1\frame%%05d.jpg -c:v libvpx-vp9 -b:v 2M -c:a libvorbis output.webm

    I am getting the right number of frames, but I can not play the output using VLC.

    • Is there any player that can play this resolution ?
    • Is there any way that I can check that the data in video is correct other than playing it ? For example by extracting them into several images and view the images.

  • ffmpeg got stuck while trying to crossfade merge two videos

    30 juin 2017, par Jeflopo

    I’m trying to do a crossfade merge (1s) between two videos. An intro (39secs duration) video with the main video. When I executed the command it started working without throwing errors but at some frame ffmpeg gets stuck.

    I read a lot of q/a here in stackoverflow, and the official docs but I can’t solve this so :

    This is the command :

    ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex \
    
    "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; \
    
    [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; \
    
    [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; \
    
    [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; \
    
    [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; \
    
    [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; \
    
    [fadein]fifo[fadeinfifo]; \
    
    [fadeout]fifo[fadeoutfifo]; \
    
    [fadeoutfifo][fadeinfifo]overlay[crossfade]; \
    
    [firstclip][crossfade][secondclip]concat=n=3[output]; \
    
    [0:a][1:a] acrossfade=d=1 [audio]" -vcodec libx264 -map "[output]" -map "[audio]" "outputs/240p.mp4"

    Here’s the raw command (the exact command I used) :

    ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; [fadein]fifo[fadeinfifo]; [fadeout]fifo[fadeoutfifo]; [fadeoutfifo][fadeinfifo]overlay[crossfade]; [firstclip][crossfade][secondclip]concat=n=3[output]; [0:a][1:a] acrossfade=d=1 [audio]" -vcodec libx264 -map "[output]" -map "[audio]" "outputs/240p.mp4"

    The "error" is reproducible with and without the -an and the acrossfade filters.

    This is the output :

    PS C:\scripts\ffmpeg> ffmpeg -i "inputs/intro.mp4" -i "inputs/240p.mp4" -an -filter_complex "[0:v]trim=start=0:end=38,setpts=PTS-STARTPTS[firstclip]; [0:v]trim=start=38:end=39,setpts=PTS-STARTPTS[fadeoutsrc]; [1:v]trim=start=1,setpts=PTS-STARTPTS[secondclip]; [1:v]trim=start=0:end=1,setpts=PTS-STARTPTS[fadeinsrc]; [fadeinsrc]format=pix_fmts=yuva420p, fade=t=in:st=0:d=1:alpha=1[fadein]; [fadeoutsrc]format=pix_fmts=yuva420p, fade=t=out:st=0:d=1:alpha=1[fadeout]; [fadein]fifo[fadeinfifo]; [fadeout]fifo[fadeoutfifo]; [fadeoutfifo][fadeinfifo]overlay[crossfade]; [firstclip][crossfade][secondclip]concat=n=3[output]; [0:a][1:a] acrossfade=d=1 [audio]" -map "[output]" -map "[audio]" "outputs/240p.mp4"
