• 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 :

• omxplayer freezes with videos generated with FFMPEG

  31 décembre 2020, par Chocksmith

  Omxplayer won't play any videos generated with FFmpeg on a Raspberry Pi

  


  I found this thread showing that it is necessary to include '-profile baseline -level 3.0' parameters : https://github.com/popcornmix/omxplayer/issues/577

  


  The full command is :

  


  ffmpeg -framerate 1/10 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p -profile baseline -level 3.0 images.mp4


  


  I did that and now I am experiencing intermittent behavior.

  


  Sometimes it works and sometimes it does not work. I cannot explain why/when it plays or not.

  


  I also found a thread showing that it is necessary to upgrade the firmware and player. I did that and still having the same issue.

  


  Here is an example. First time it plays ok. Second time it freezes.

  


  First time : creating mp4

• Create HLS streamable audio file from mp3

  15 août 2023, par isADon

  I am using following command to create a hls aac audio file for web streaming

  



  ffmpeg -y -i song.mp3 -c:a aac -b:a 128k -f hls -hls_time 7 -hls_list_size 0 -hls_segment_filename file%d.m4a playlist.m3u8


  



  This command works only with some audio files. With many mp3 files I receive following output :

  



  C:\ffmpeg>ffmpeg -y -i song.mp3 -c:a aac -b:a 128k -f hls -hls_time 7 -hls_list_size 0 -hls_segment_filename file%d.m4a playlist.m3u8
