• Errors while ffmpeg compiling

  10 mai 2012, par iSun

  I trying to compile ffmpeg through the following script, but I got errors while compiling : (Using windows 7 - android ndk 7rb and cygwin)

  s@s-PC /cygdrive/f/export/ffmpeg-0.8.10
  
  $ ./setup.sh
  
  F:/Compiler/android-ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/wind                                                                                                    ows/bin/arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

• FFmpeg Video Overlay Function Not Working (Flutter)

  30 août 2022, par Dennis Ashford

  I am simply trying to get a watermarked video from the Flutter FFmpeg package and cannot seem to get it to work. For right now, I am downloading the video from Firebase, storing it in cache, overlaying a watermark image using the Flutter FFmpeg Kit package. The original video file, image file, and output file are being created properly. However, the overlay function is not working properly. Can someone help me with the FFmpegKit.execute function string ? I am not seeing any obvious errors in the function, but it isn't working properly. I tried writing as a new File and asBytes but neither worked.

  


  Edit : I want to take the originalVideo and overlay it with the watermark image with the expected outcome being a new file that contains the new overlayed video. Not concerned with where the overlay is yet.

  


  Pubspec.yaml

  


  ffmpeg_kit_flutter: ^4.5.1


  


  The function is :

  


  import &#x27;package:ffmpeg_kit_flutter/ffmpeg_kit.dart&#x27;;&#xA;&#xA;Future<file> waterMarkVideo(String videoPath, String watermarkPath) async {&#xA;    //these calls are to load the video into temporary directory&#xA;    final response = await http.get(Uri.parse(videoPath));&#xA;    final originalVideo = File (&#x27;${(await getTemporaryDirectory()).path}/video.mp4&#x27;);&#xA;    await originalVideo.create(recursive: true);&#xA;    await originalVideo.writeAsBytes(response.bodyBytes);&#xA;    print(&#x27;video path&#x27; &#x2B; originalVideo.path);&#xA;&#xA;    //this grabs the watermark image from assets and decodes it&#xA;    final byteData = await rootBundle.load(watermarkPath);&#xA;    final watermark = File(&#x27;${(await getTemporaryDirectory()).path}/image.png&#x27;);&#xA;    await watermark.create(recursive: true);&#xA;    await watermark.writeAsBytes(byteData.buffer.asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));&#xA;    print(&#x27;watermark path&#x27; &#x2B; watermark.path);&#xA;&#xA;    //this creates temporary directory for new watermarked video&#xA;    var tempDir = await getTemporaryDirectory();&#xA;    final newVideoPath = &#x27;${tempDir.path}/${DateTime.now().microsecondsSinceEpoch}result.mp4&#x27;;&#xA;    final videoFile = await File(newVideoPath).create();&#xA;&#xA;//overlaying video using FFmpegkit where I need some help&#xA;    await FFmpegKit.executeAsync("-i $originalVideo -i $watermark -filter_complex &#x27;overlay=(W-w)/2:(H-h)/2&#x27; $videoFile")&#xA;    .then((session) async {&#xA;      final state = FFmpegKitConfig.sessionStateToString(await session.getState());&#xA;      final returnCode = await session.getReturnCode();&#xA;      final failStackTrace = await session.getFailStackTrace();&#xA;      final output = await session.getOutput();&#xA;      print(&#x27;FFmpeg process exited with state ${state} and rs ${returnCode}.If failed ${failStackTrace}&#x27;);&#xA;      print(&#x27;Last output $output&#x27;);&#xA;    } );&#xA;    print(&#x27;new video path&#x27; &#x2B; newVideoPath);&#xA;    Uint8List videoByteData = await videoFile.readAsBytes();&#xA;    return videoFile.writeAsBytes(videoByteData);&#xA;}&#xA;</file>

  


  The output for the function above is

• FFmpeg video overlay function not working

  5 novembre 2022, par Dennis Ashford

  I am simply trying to get a watermarked video from the Flutter FFmpeg package and cannot seem to get it to work. Right now, I am downloading the video from Firebase, storing it in cache, overlaying a watermark image using the Flutter FFmpeg Kit package. The original video file, image file, and output file are being created properly.

  


  However, the overlay function is not working properly. How can I use the FFmpegKit.execute function string ? I am not seeing any obvious errors in the function, but it isn't working properly. I tried writing as a new File and asBytes but neither worked.

  


  Edit : I want to take the originalVideo and overlay it with the watermark image with the expected outcome being a new file that contains the new overlayed video. Not concerned with where the overlay is yet.

  


  Pubspec.yaml

  


  ffmpeg_kit_flutter: ^4.5.1


  


  The function is :

  


  import &#x27;package:ffmpeg_kit_flutter/ffmpeg_kit.dart&#x27;;&#xA;&#xA;Future<file> waterMarkVideo(String videoPath, String watermarkPath) async {&#xA;    //these calls are to load the video into temporary directory&#xA;    final response = await http.get(Uri.parse(videoPath));&#xA;    final originalVideo = File (&#x27;${(await getTemporaryDirectory()).path}/video.mp4&#x27;);&#xA;    await originalVideo.create(recursive: true);&#xA;    await originalVideo.writeAsBytes(response.bodyBytes);&#xA;    print(&#x27;video path&#x27; &#x2B; originalVideo.path);&#xA;&#xA;    //this grabs the watermark image from assets and decodes it&#xA;    final byteData = await rootBundle.load(watermarkPath);&#xA;    final watermark = File(&#x27;${(await getTemporaryDirectory()).path}/image.png&#x27;);&#xA;    await watermark.create(recursive: true);&#xA;    await watermark.writeAsBytes(byteData.buffer.asUint8List(byteData.offsetInBytes, byteData.lengthInBytes));&#xA;    print(&#x27;watermark path&#x27; &#x2B; watermark.path);&#xA;&#xA;    //this creates temporary directory for new watermarked video&#xA;    var tempDir = await getTemporaryDirectory();&#xA;    final newVideoPath = &#x27;${tempDir.path}/${DateTime.now().microsecondsSinceEpoch}result.mp4&#x27;;&#xA;    final videoFile = await File(newVideoPath).create();&#xA;&#xA;//overlaying video using FFmpegkit where I need some help&#xA;    await FFmpegKit.executeAsync("-i $originalVideo -i $watermark -filter_complex &#x27;overlay=(W-w)/2:(H-h)/2&#x27; $videoFile")&#xA;    .then((session) async {&#xA;      final state = FFmpegKitConfig.sessionStateToString(await session.getState());&#xA;      final returnCode = await session.getReturnCode();&#xA;      final failStackTrace = await session.getFailStackTrace();&#xA;      final output = await session.getOutput();&#xA;      print(&#x27;FFmpeg process exited with state ${state} and rs ${returnCode}.If failed ${failStackTrace}&#x27;);&#xA;      print(&#x27;Last output $output&#x27;);&#xA;    } );&#xA;    print(&#x27;new video path&#x27; &#x2B; newVideoPath);&#xA;    Uint8List videoByteData = await videoFile.readAsBytes();&#xA;    return videoFile.writeAsBytes(videoByteData);&#xA;}&#xA;</file>

  


  The output for the function above is
