  • ffmpeg watermark to mp4

    20 octobre 2013, par user2899426

    Trying to add a png graphic as watermark to an existing mp4 video with audio. But each time I produce an ouputfile there is no audio included / encoded ? For testing pupose i only want a small 30 second clip

     ffmpeg -t 0:0:30.0 -i 'input.mp4' -i 'logo.png' -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' -b:v 5842k -c:a copy out.mp4

    have managed to extract audio to seperate mp3 file to check codec works

    FYI built ffmpeg from gitclone Thanks this is driving me nuts.

  • ffmpeg - over 1000 files into a mp4

    20 octobre 2013, par Fabrizio

    I am using FreeBSD and ffmpeg and I am trying to convert over 1000 files into an mp4. Keep in mind that I am completely NEW to ffmpeg and that in the future I might have up to 3600 images.

    I was thinking that simply executing:

    ffmpeg -i /usr/local/www/tmp/phpFa5LT3/*.jpg -r 2 output.mp4

    would work, but I keep getting

    When I try:

    ffmpeg -y -f image2 -r 4 -i /usr/local/www/tmp/phpFa5LT3/%14d.jpg output.mp4

    I get:

    [same output but last line reads]

    If I reduce the number of files to just a 100 or so, I can do it without any problems... Do you know what the problem might be ?

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg does.

    I was wondering if this was either: A) An issue with the way my server is encoding NAL units, or B) An issue with my Android client, specifically the way it is receiving and decoding NAL units.

    My encoding configuration with x264 is:

    x264_param_default_preset(&param,"ultrafast", "zerolatency:fastdecode");
param.i_threads = 1;
param.i_bframe = 1;
param.i_width = image_width;
param.i_height = image_height;
param.i_fps_num = 60;
param.i_fps_den = 1;
param.i_keyint_max = 10;

param.rc.i_rc_method = X264_RC_ABR;
param.rc.i.bitrate = 6000;
param.i_sps_id = 7;
param.b_repeat_headers = 1;
param.b_annexb = 0;

    My Android MediaCodec client is set up as follows:

    I receive each individual NAL unit on a separate Live 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs from this queue, and if there are none available, waits until there are.

    Some notes:

    What I generally see happen is the queue starts filling up with NALs, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates-- also again, it DID work when I was using ffmpeg to encode. If I omit certain NAL units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.

    Edit:

    Here is a log of the Android client, as well as a log highlighting the garbage collector specifically--

  • ffmpeg apply filters without rencoding ?

    19 octobre 2013, par nbubis

    I want to rotate a video using ffmpeg, but I don't want to lose quality by re-encoding.

    If I try

    ffmpeg -i in.mp4 -vf 'vflip,hflip' -ss 120 -t 200 -c:v copy -c:a copy out.mp4

    No rotation gets preformed. If I instead specify the encoding by using, say -c:v h264, I'm afraid I'll lose some quality. Is there a "losssless" (relative to the original encoding) way of applying a filter?

  • FFMPEG : Change Video during encoding (using mapping)

    18 octobre 2013, par Tchoupi

    I'm currently trying to concat several videos using a complex filter:

    ffmpeg.exe -threads 8 -i "D:\Temporary0.mp4"  -i "D:\Temporary1.mp4"  -i "D:\Temporary2.mp4"  -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a]  concat=n=3:v=1:a=1 [v] [a] " -map "[v]" -map "[a]"  -vcodec libx264 -b 2500000 -s 1920:1080 -y D:\EditedVideo.mp4

    This command work fine. Edit: Here the output of the command:

    I would like to update this command to change volume during concat and encode time:

    ffmpeg.exe -threads 8 -i "D:\Temporary0.mp4"  -i "D:\Temporary1.mp4"  -i "D:\Temporary2.mp4"  -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a]  concat=n=3:v=1:a=1 [v] [a] " -map "[v]" -map "[a]"  -vcodec libx264 -b 2500000 -s 1920:1080 -af volume="volume=20dB:precision=double" -y D:\EditedVideo.mp4

    This command is executed but the audio stream is not altered with the +20db

    PS: If I do a simple encoding command like

    ffmpeg.exe -i source -vcodec libx264 -af volume="volume=20dB:precision=double" -y output

    Command work fine and audio stream is modified.

    So How can I Do to concat my videos and change audio volume at the same time ?

    Thanks
