• How can i create a portrait video using Android's MediaRecorder

  23 mars 2015, par urudroid

  I have an Android application which is able to record and play a videos in portrait mode, those features are working fine on Android phones.

  The issue comes up because this video is needed to be played also on iOS devices (after being shared through a server).

  iOS is not correctly showing the video as it looks "cropped", but videos recorded on iOS are played without issues.

  So, the main difference between videos created on Android and iOS’ is the size and the rotation.

  Im using CWAC-Camera library for preview and recording and ffmpeg to scale the video down to 320x568px (as this is the standard size for both Android and iOS apps).

  Here is the metadata from an video created from Android :

  The values width and height are inverted on Android, also the Rotation parameter is set to 270º (this is the rotation parameter for portrait videos).

  This is a sketch of how iOS’ videos look on iOS app :

  

  And this is how Android’s videos look on iOS app :

  

  So, in order to get the videos correctly displayed both on iOS and Android i need to be able to set the width to 320 and height to 568 on Android. I tried it from several places (outside and inside CWAC-Camera library) but i always get a Camera.Parameters error.

  It is possible to do this on Android ?

  EDIT :

  This is the result i get when i set the rotation to 0 with ffmpeg :

  

• 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.

  3. 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.

  4. 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)

                  ffmpeg.StartInfo.Arguments = " -i \"" + input + "\" -vframes 1 \"" + output + "\"";
  
              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 + "\"";
