• Low processing for conversation of .MOV file to .mp4 using ffmpeg [closed]

  4 janvier 2021, par zain rauf

  I am using the below CMD for converting .mov file to .mp4 with following resolution options

  


  ffmpeg -y -i 'Aws s3 video link of .mov file' -vcodec h264 -acodec acc -vf scale=1080:1920,setsar=1:1 -q:a 10 -q:v 3 -preset ultrafast -r 25 -f mp4 -c:a copy tmp/filename-resize.mp4

  


  Issue is that it works very slow when i am using input file as a AWS s3 video link

  


• ffmpeg export without color loss

  27 décembre 2020, par ser

  I'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?

  


  Currently, I use this code :

  


  ./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "


  


  I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)

  


  I also get this error when I run ffpmeg :

  


  [swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly


  


  See Image comparison here — the blacks on the export were not as "black" as original

• ffmpeg capture video and audio produced corrupt output

  18 décembre 2020, par wheelie tips

  I have two separate FFmpeg commands that each works well on its own, one for capturing video and the other for capturing audio from the same device ; the captured audio is :

  


  ffmpeg -f alsa -thread_queue_size 16384 -i hw:CARD=C4K,DEV=0 -acodec aac /home/pi/Videos/temp.wav


  


  and the captured video is :

  


  ffmpeg -y -nostdin -f v4l2 -threads auto -input_format yuyv422 -fflags +genpts -flags +global_header -thread_queue_size 16384 -i /dev/video0 -s 1280x720 -r 25 -vcodec h264_v4l2m2m -num_output_buffers 32 -num_capture_buffers 16 -keyint_min 25 -force_key_frames "expr:gte(t,n_forced*1)" -g 50 -b:v 6M -pix_fmt nv12 -f mpegts -muxdelay 0 -muxpreload 0 -movflags +faststart /home/pi/Videos/output.mp4


  


  I’ve tried to combine the two into one call to produce one video file with the audio channel, but whatever I’ve been attempting, the results output were messed up ; obviously, I’m missing something, for example, my latest attempt prodused a frozen image video with the audio channel :

  


  ffmpeg -y -nostdin -f v4l2 -threads auto -input_format yuyv422 -fflags +genpts -flags +global_header -thread_queue_size 16384 -i /dev/video0 -f alsa -thread_queue_size 16384 -i hw:CARD=C4K,DEV=0 -acodec aac -s 1280x720 -r 25 -vcodec h264_v4l2m2m -num_output_buffers 32 -num_capture_buffers 16 -keyint_min 25 -force_key_frames "expr:gte(t,n_forced*1)" -g 50 -b:v 6M -b:a 128K -pix_fmt nv12 -f mpegts -muxdelay 0 -muxpreload 0 -movflags +faststart /home/pi/Videos/output.mp4 -loglevel debug
