• How do you use FFMPEG to transcode h264_qsv from Apple PRORES Quicktime ?

  4 décembre 2022, par RCJetPilot

  I am trying to transcode an Apple Prores 444 to H.264 using qsv without success.

  


  If I use this command line :

  


  ffmpeg -i 10minute_Pipeline_Test.mov -c:v h264_qsv -c:a aac -pix_fmt qsv  chris.mp4

  


  I get :

  I cannot get ANYTHING to work. I can transcode other h264 files without issue. I cannot seem to transcode this prores file.

  


  Here is a link to the source file if anyone can help I would REALLY appreciate it...

• xabe.ffmpeg not working in azure app service

  28 décembre 2020, par Sripathi Raja

  I have a .net core application which generates video thumbnails for uploaded videos. I am using xabe.ffmpeg for this . The code runs fine in the local system and Iam able to generate the thumbnails . I have containerized this application and pushed it to azure app service . But when the code is deployed on azure app service its throws an error . I have placed the ffmpeg.exe ,ffprobe.exe , ffplay.exe inside a folder ffmpeg in wwwroot folder .
the app service logs give this error

  


  the first line is the path : /app/wwwroot/ffmpeg

• 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 :

  &#xA;

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


  &#xA;

  and the captured video is :

  &#xA;

  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


  &#xA;

  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 :

  &#xA;

  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


  &#xA;

  the full output of the above command :
