  • keepalive type and frequency in ffmpeg [on hold]

    19 novembre 2013, par Jack Simth

    My company has a bunch of IP cameras that we distribute - specifically Grandstream - and the manufacturer has changed their firmware. The normal keepalive that ffmpeg uses for the rtsp streams ( either ff_rtsp_send_cmd_async(s, "GET_PARAMETER", rt->control_uri, NULL) ; or ff_rtsp_send_cmd_async(s, "OPTIONS", "*", NULL) ; both in in libavformat/rtspdec.c) is no longer working, for two reasons :

    1) The new Grandstream firmware is now checking for a receiver report to determine whether or not the program reading the stream is live, not just anything.

    2) The new Grandstream firmware requires that the receiver report to keep the connection alive happen at least once every 25 seconds, and on the audio stream it is currently only happening about every 30 seconds or so (video is getting it every 7 seconds or so).

    So after about a minute with ffmpeg connected, the camera stops sending the audio stream, the audio stream on ffmpeg reads end-of-file, and then ffmpeg shuts everything down.

    As I can't change the firmware, I'm trying to dig through the ffmpeg code to make it send the appropriate receiver report for the keep alive... but I am getting nowhere. I've added a little snippet of code into the receiver reports so I know when they're running when I call ffmpeg on debug, but... well, it's not going well.

    Test command :
    ffmpeg -loglevel debug -i rtsp ://admin:admin@192.168.4.3:554/0 -acodec libmp3lame -ar 22050 -vcodec copy -y -f flv /dev/null &> test.txt

    Test output :

  • 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
