  • ffmpeg does not copy custom metadata

    20 juin 2015, par e110c0

    I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

    I tried a couple of versions, all with the same result, e.g. :

    ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

    This should work, it already gives the correct preview of metadata :

    I also tried to add the one tag I’m interested in by hand with

    -metadata:g location=+48.2683+007.7205+172.710/

    with no change in the result.

    Output as .mov doesn’t change anything, neither.

    Is there any trick to add non-standard metadata ? How do I get the location back in there ?

    Thanks in advance to anyone who can give some insight on this.

  • Android FFmpeg sometimes works and sometimes crashes

    20 novembre 2013, par Pawel Cala

    I compiled FFmpeg for Android ( https://gitorious.org/android-ffmpeg ) but when I'm trying to do some operations ( f.e filters cropping, transpose, trim etc ) it crashes in 5 on 10 cases.
    Error logs are not the same so I assume that it might be caused by memory issues.
    I'm using OSX, NDK android-ndk-r9b : darwing x86_64.
    Native ffmpeg method is passing args to ffmpeg.c main method. It's executed in AsyncTask in Activity.
    Thanks in advance

    EDIT :
    I forgot to mention that programs algorithm runs like that :
    Press Button - > Open Camera Intent - > Start recording - > After recording copy file to project folder ( on SD card ) - > Open edit activity + Start asynctask

    EDIT2 :
    Tested on HTC ONE with different video resolutions

  • Retrieving RTP time from an IP camera programatically using FFMPEG

    22 novembre 2013, par Dídac Pérez

    I am using the ffmpeg C/C++ library to get the video stream from an IP camera using methods such as avformat_open_input(), av_read_frame(), etc... I would like to get the RTP time from the camera. pts and dts values give me the relative timestamp to the first frame, but I need the absolute date (i.e. 2013/11/22 12:40:30.123) and time since as I read, at the RTP layer the time is sent by the camera, and I have also configured the camera to use the dime from an NTP server.

    Please, I am really confused and I have tried everything without success, I am not able to find this date and time. Any help will be really appreciated, thank you so much.
