  • undefined reference error while building FFMPEG with NDK

    22 mars 2015, par dev123

    I get this error while running build-ndk for my ffmpeg android project

    make: *** [obj/local/armeabi-v7a/libffmpeg-test-jni.so]
undefined reference to 'av_close_input_file'
undefined reference to 'av_find_stream_info'
undefined reference to 'av_open_input_file' 
undefined reference to 'avcodec_open'

    Any solutions to get rid of this error ? I am very new to ffmpeg and Android NDK

    This is my Android MK file

    LOCAL_PATH := $(call my-dir)

  • Using AForge.Net for commercial closed-source applications

    22 mars 2015, par ilay zeidman

    I have application that our company want to make a product from. The application uses AForge.Net and in the AForge.Video.FFMPEG.dll which is under GPL v3 license. You can see AForge.net license

    My question: can I use this dll in my product? Do my product have to be under gpl3 and the source should be available?

      for each frame start with 21 xxxx ff-ff ,for example

      21-4E-FE-FF-FF.....
21-4D-FE-FF-FE....

      so do you know what this header mean ?

      few of samples is have the size 9 byte and take one of these values (21-00-49-90-02-19-00-23-80) or (20-00-49-90-02-19-00-23-80) so do you know what these samples mean ?

      always the first sample reserved 26 byte and have the values (DE-04-00-00-6C-69-62-66-61-61-63-20-31-2E-32-38-00-00-42-00-93-20-04-32-00-47) so do you know what these sample mean ?

    • Converted Avi to Mp4 using FFMPEG, Converted video not working in html 5 Tag

      21 mars 2015, par Suprabhat

      I have a section in my web page where user can upload any types of videos of any format , currently only restricted to .mp4 and .avi. After successfull upload i have displayed the same video to the user. I have bind the path in HTML5 video so that the user can view the content he/she has uploded. Video with extension .mp4 no doubt are working properly as HTML5 support them. Tricky part is it don't support Avi files. Now here what the problem has arised. In order to display avi videos i have used FFMPEG to convert videos with extension .avi to .mp4. With lots of googling and reading forum, i have succesfully converted avi videos to mp4 . Here's what i have used :-

      1. ffmpeg -i input.avi -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

      2. ffmpeg -i input.avi -c:v libx264 -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

      Above two are working perfectly, they have succesfully converted the video. But when i run them on browser in HTML5 and in new tab (Flash Player Plugin Installed), HTML5 doesn't play it and flash player return an error message "Video can't be played because the file is corrupt". But when i played them on KMplayer and in Window media player they are running perfectly.

      I have been to various threads in stackoverflow related to convert avi to mp4 and here i found following in one of the forum. where one of user has accepted this a correct answer but it ain't worked out for me.

      1. ffmpeg -y -i sample.avi -b:v 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 sample.mp4

      Above argument returned me following error "File for preset 'slow' not found".

      Following my futher searches i came across this thread ffmpeg convert mov file to mp4 for HTML5 video tag IE9. Here following argument worked perfectly and it able to convert video in such way that it is playble on browser.

      1. ffmpeg -y -i input.avi -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k -pix_fmt yuv420p output.mp4.

      Problem i faced here was video is converted to 420p reso which quality is noty upto mark. Smaller resolution videos are been enlarged and seems pixelated

      Thus, i had to finally put up a question. I will be very obliged if someone can give a solution for above problem. I need to convert an avi video to mp4 supported by HTML5 video tag. It should able to play it on browser and during conversion of video it should maintain original audio and video quality plus resolution.

      Thanks

      My C# Code:

              public void Create(string input, string output, string parametri, string ThumbnailPhysicalPath, int ConvertType)

            else if (ConvertType == Convert.ToInt32(ConversionType.AviToMp4))
                ffmpeg.StartInfo.Arguments = " -i \"" + input + "\" -c:v libx264 -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 \"" + output + "\"";

                string error = ffmpeg.StandardError.ReadToEnd();
            }

                Common.WriteLog("Exception occurred during conversion. Error Message :- " + Ex.Message + "\n Input Parameter :- " + input+ "\n Output Paramenter :- "+ output);
            }
            finally
            {
                ffmpeg.Close();
                if (ConvertType == Convert.ToInt32(ConversionType.AviToMp4))
