• Ffmpeg command to create mp4 video sharable to Instagram, etc

  5 février 2019, par Ken Rothman

  I’m creating an mp4 video in my Android application by combining a static 1080x1080 .png image with 24/48 .wav audio, trying to generate a file that is compatible with and can be shared to social media platforms, such as Facebook and Instagram (feed).

  When I attempt to share the videos I’ve created, they load and preview in the Instagram app (tested on both Android and iOS), but after hitting the "Share" button on the final step, the UI returns to my feed and the upload progress immediately switches to "Not Posted Yet. Try Again". If I then tap the retry button, I immediately get a dialog stating "Couldn't Post Video" "There was a problem rendering your video. If this keeps happening, you may have to use another video."

  I’m using ffmpeg (via tanersener’s mobile-ffmpeg library) to do this.

  All of the documentation I’ve found this far does not show highly specific details for upload requirements for Instagram.
  I’m using AAC for audio, and h.264 (libx264) for video.
  The sample I’m using has a duration of 30 seconds. The PNG, as mentioned above, is 1080x1080.

  I’ve taken Android out of the picture by using cmd-line ffmpeg on my Mac with the same input files and testing many variations of parameters, none of which create an uploadable video.

  I have a similar .mp4 file created by our iOS app (not using ffmpeg), which I brought over to my Android device and it uploads successfully.
  I’ve also sent my .mp4 file to the iOS device and it will not upload, so it seems likely it’s an encoding issue of some sort.

  I have yet to find a combination of ffmpeg parameters that generate a video that can be successfully shared to Instagram.

  Is there a way to get verbose logs from Instagram to have some sort of idea why it’s rejecting the files ?

  This is the ffmpeg command I’ve been concentrating on :

  ffmpeg -i test.wav -i test.png -c:a aac -b:a 256k -ar 44100 -c:v libx264 -b:v 5M -r 30 -pix_fmt yuv420p -preset faster -tune stillimage test.mp4

  I’ve tried all sorts of variations of video and audio bitrates, framerates, scaling, presets, tunes, profiles, etc. But no luck as of yet.

  Does anyone have a working ffmpeg command for generating videos for Instagram ?

• Annual Release of External-Videos plugin – we’ve hit v1.0

  13 janvier 2017, par silvia

  This is the annual release of my external-videos wordpress plugin and with the help of Andrew Nimmolo I’m proud to annouce we’ve reached version 1.0 !

  So yes, my external-videos wordpress plugin is now roughly 7 years old, who would have thought ! During the year, I don’t get the luxury of spending time on maintaining this open source love child of mine, but at Christmas, my bad conscience catches up with me – every year ! I then spend some time going through bug reports, upgrading the plugin to the latest wordpress version, upgrading to the latest video site APIs, testing functionality and of course making a new release.

  This year has been quite special. The power of open source has kicked in and a new developer took an interest in external-videos. Andrew Nimmolo submitted patches over all of 2016. He decided to bring the external-videos plugin into the new decade with a huge update to the layout of the settings pages, general improvements, and an all-round update of all the video site APIs which included removing their overly complex SDKs and going straight for the REST APIs.

  Therefore, I’m very proud to be able to release version 1.0 today. Thanks, Andrew !

  Enjoy – and I look forward to many more contributions – have a Happy 2017 !

  NOTE : If you’re upgrading from an older version, you might need to remove and re-add your social video sites because the API details have changed a bit. Also, we noticed that there were layout issues on WordPress 4.3.7, so try and make sure your WordPress version is up to date.

• FFMPEG library Integration unsuccess

  1er septembre 2017, par Alok Kumar Verma

  I’m stuck with the integration of the FFMPEG file. I’m using Android Studio 2.3.3

  I’ve followed this link and hence got to know how to do this but all I’m getting is a failure.

  Links

  1. How to integrate the FFMPEG in your android
  2. Integrating android FFMPEG

  Now I"ve my ndk installed in this path : /Users/alok/Library/Android/sdk/ndk-bundle

  And I’ve downloaded the newest version of the FFMPEG i.e., 3.3.3 unzipped it in the sources folder of ndk-bundle

  Now I’ve followed this and implemented everything as said.

  • Editing the Configure File using TEXTVIEW in my mac

  • Creating a file name build_android.sh and copy pasting the given code. However I’ve changed the NDK path in my case in the code the code is here

    NDK=/Users/alok/Library/Android/sdk/ndk-bundle
SYSROOT=$NDK/platforms/android-23/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64

  • Now opening the folder through terminal and then typing this command sudo chmod +x build_android.sh followed by this sudo ./build_android.sh

  The result is : No android name folder created inside under the folder FFMPEG 3.3.3 in this root i.e., /ndk-bundle/sources/ffmpeg 3.3.3/

  and the terminal shows this output :

  ./configure: line 3341: syntax error near unexpected token `2'

  ./configure: line 3341:

  DEPCMD='$(DEP$(1)) $(DEP$(1)FLAGS) $($(1)DEP_FLAGS) $< 2>/dev/null | sed -e "/^\#.*/d" -e "s,^[[:space:]]*$(@F),$(@D)/$(@F)," > $(@:.o=.d)''
Makefile:2: config.mak: No such file or directory
Makefile:67: /common.mak: No such file or directory
Makefile:114: /libavutil/Makefile: No such file or directory
Makefile:114: /library.mak: No such file or directory
Makefile:116: /doc/Makefile: No such file or directory
Makefile:206: /tests/Makefile: No such file or directory
make: *** No rule to make target /tests/Makefile'. Stop.

  Hence I’m not been able to move next due to this which creating a JNI folder and stuff. I’m a beginner with FFMPEG and want to integrate it.

  NOTE : I’ve already used this library in my gradle

  compile ‘com.writingminds:FFmpegAndroid:0.3.2’

  For easy approach and things are working fine too but due to the older version I’m getting wrong outputs, so need to update it and there is one way and this is the way to do it.
