How can i create a portrait video using Android's MediaRecorder
23 mars 2015, par urudroidI 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 :

Tagged date : UTC 2015-03-17 19:16:37The 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 :

How to remove long silent and unchanged video sections with ffmpeg ?
18 mars 2015, par samuiraiI want to identify areas in a
.mp4(H264 + AAC) video that are silent and unchanged frames and cut them out.
Of course there would be some fine-tuning regarding thresholds and algorithms to measure unchanged frames.- My problem is more general, regarding how I would go about automating this ?
- Is it possible to solve this with
ffmpeg? (preferably with C or python) - How can I programatically analyse the audio ?
- How can I programatically analyse video frames ?

The file has a good size but comes up as length 0.04 tells me that my time stamping must be broken between the frames / pkts, but I am unsure on how to fix this issue.
I tried inspecting the file with ffmpeg.exe using ffmpeg -i and outputting to a regular TS. It seems my code works more then I originally intended however, I am simply trying to output a bunch of all white frames.
