  I just need to enable gd support for ffmpeg. I’ve tried using ./configure --enable-skip-gd-check and nothing has worked. I’ve scoured google for the last 12 hours and tried every "solution" so any advice is appreciated. Thanks.

  Terminal output after ./configure --enable-skip-gd-check :

• Setting video stream metadata using Ffmpeg

  26 mai 2015, par Edson Menegatti

  I’m using the JavaCV FFmpegFrameRecorder class to encode Android’s camera preview frames into a video.

  The goal would be to replicate the result of the following command line :

  ffmpeg -i input.mp4 -metadata:s:v:0 rotate="90" output.mp4

  I modified the startUnsafe() method as follows, but it failed to generate the desired output :

  if ((video_st = avformat_new_stream(oc, video_codec)) != null) {
  
          video_c = video_st.codec();
  
          video_c.codec_id(oformat.video_codec());
  
          video_c.codec_type(AVMEDIA_TYPE_VIDEO);
  
          ...
  
          AVDictionary avDictionary = new AVDictionary(null);
  
          av_dict_set(avDictionary, "rotate", "90", 0);
  
          video_st.metadata(avDictionaty);
  
          ...
  
  }
  
  ...
  
  avformat_write_header(oc, (PointerPointer) null);

  This still encodes the video correctly, but the added metadata never appears on ffprobe. If it helps, the video encoding is h264.

  By the way, here’s the ffprobe output :

• Merging video and audio stream, where audio drifts

  22 avril 2015, par TL_IPD

  I want to record audio and video with my raspberry pi b+ 2.
  I tried to accomplish this with one ffmpeg command but this is to slow. and i could not get it working correctly

  I have a raspberry pi camera module and a Cirrus audio card. On the raspberry i have compiled a new kernel with support for the audio card. I also compiled ffmpeg on the raspberr with alsa support

  ~$ ffmpeg

  usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

  Now i try to record an audio stream and a video stream ’at the same time’
  I do this my running a shell script

  raspivid -t 60000 -vs -w 1280 -h 720 -b 5000000 -fps 25 -o video.h264 &
  
  arecord -Dhw:sndrpiwsp -r 44100 -c 2 -d 60 -f S32_LE audio.aac

  i also tried with -r 22050 and -f S16_LE

  when running this it sometimes gives an (i think)

  overrun!!! (at least 1038.725 ms long)

  at the end of the script i have two files. a video and a audio file.

  now i want to merge those two together by using ffmpeg

  ffmpeg -i video.h264 -i audio.aac -c:v copy -c:a aac -strict experimental output.mp4

  this gives the output :

  so finally i have a file output.mp4 that is a movie with audio that is in sync at the beginning but drifts away to a difference of about 4 seconds. where the audio is ahead of the video.

  I hope you can help me trying to solve this issue so the audio does not drift away anymore.

  Thanks in advance

  ( i tried to be as clear as possible )
