• 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


  


  the full output of the above command :

• ffmpeg exported .mp4 files won't open in premiere pro or vegas

  16 décembre 2020, par Bernhard Alber

  i recently used ffmpeg to add together roughly 350+ .mp4 files into one big file and then deleted the audio from that file.

  


  However when importing the .mp4 file into Premiere Pro it keeps on telling me that the file is an unsupported file format or damaged file. It opens perfectly fine in VLC tho.

  


  -i in ffmpeg gave me the following :

• How can I capture simple video input with audio from a capture device

  17 décembre 2020, par Geoff Sweet

  I'm using ffmpeg on Arch linux and trying to convert some old video to digital. The setup is pretty straightforward and if I connect to the capture device with VLC I get the video and audio just fine. So now I want to capture that with ffmpeg and write it to a file so I can edit it and clean it up. I'm only so-so familiar with ffmpeg and I've been digging through the man pages and here is where I am at.

  


  This command captures perfect audio, but no video :

  


  ffmpeg -f alsa -ac 2 -i front:CARD=Capture,DEV=0 out.mpeg


  


  This command captures perfect video ;

  


  ffmpeg -f video4linux2 -i /dev/video0 out.mpeg


  


  captures the video signal great, but with no audio. So combining them together should give me :

  


  ffmpeg -y -f alsa -ac 2 -i front:CARD=Capture,DEV=0 -f video4linux2 -i /dev/video0 out.mpeg


  


  But that command kinda falls on it's face. I get the audio, but no video :

  


  ffmpeg -y -f alsa -ac 2 -i front:CARD=Capture,DEV=0 -f video4linux2 -i /dev/video0 out.mpeg

  what I would ideally like is just a fairly raw 2ch stereo "dump" of what comes through the capture card.

  


  As always, I super appreciate any advice
