  • FFMPEG/avconv option -c:a copy

    1er juin 2013, par b747fp

    I am converting a bunch of videos from FLV to MP4 (for iphone compatibility) and using AAC codec it kept throwing out "invalid audio bitrate" or similar errors. I tried "-c:a copy" option and it works, but I am wondering if that tells ffmpeg to use the original MP3 codec or just the original audio bitrates/frequencies ?

  • Image to MPEG on Linux works, same code on Android = green video

    27 novembre 2014, par JScoobyCed

    EDIT
    I have check the execution and found that the error is not (yet) at the swscale point. My current issue is that the JPG image is not found :
    No such file or directory
    when doing the avformat_open_input(&pFormatCtx, imageFileName, NULL, NULL);
    Before you tell me I need to register anything, I can tell I already did (I updated the code below).
    I also added the Android permission to access the external storage (I don’t think it is related to Android since I can already write to the /mnt/sdcard/ where the image is also located)
    END EDIT

    I have been through several tutorials (including the few posted from SO, i.e. http://dranger.com/ffmpeg/, how to compile ffmpeg for Android...,been through dolphin-player source code). Here is what I have :
    . Compiled ffmpeg for android
    . Ran basic tutorials using NDK to create a dummy video on my android device
    . been able to generate a MPEG2 video from images on Ubuntu using a modified version of dummy video code above and a lot of Googling
    . running the new code on Android device gives a green screen video (duration 1 sec whatever the number of frames I encode)

    I saw another post about iPhone in a similar situation that mentioned the ARM processor optimization could be the culprit. I tried a few ldextra-flags (-arch armv7-a and similar) to no success.

    I include at the end the code that loads the image. Is there something different to do on Android than on linux ? Is my ffmpeg build not correct for Android video encoding ?
