  • ffmpeg command failed

    25 octobre 2015, par Asad kamran

    I am experimenting FFMPEG command to convert any video format to mp4.

    Server admin execute the below command created by me and show me the errors :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    This is error :

    [aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
    codecs are not enabled, add ’-strict -2’ if you want to use it.

    how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.

    my ffmpeg and server are as follow :

    ffmpeg version N-75903-g14573b9 Copyright (c) 2000-2015 the FFmpeg
    developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)

    EDIT 1 :
    I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :

    New command :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    After executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
    Its Log is as follow :

  • How to parse ffmpeg -list_options output to get complete list of formats ?

    9 octobre 2024, par gaamaa

    On my Windows 10, application I use VB6 and ffmpeg.exe to capture video from USB capture device.
I need to show complete list of supported formats by this capture card.

    


    When I use below command I get some list.
But its looks incomplete for me.

    


    
    ffmpeg -f dshow -list_options true -i video="USB3. 0 capture"



    


    Result :

    My question is :

    


    How to get the proper list in-between min and max ?

    


    Eg :
Please see the below 4 lines.

    


     vcodec=mjpeg  min s=1920x1080 fps=10 max s=1920x1080 fps=60.0002
 vcodec=mjpeg  min s=1920x1080 fps=10 max s=1920x1080 fps=60.0002
 vcodec=mjpeg  min s=1600x1200 fps=10 max s=1600x1200 fps=60.0002
 vcodec=mjpeg  min s=1600x1200 fps=10 max s=1600x1200 fps=60.0002


    


    It says
min fps=10
max fps=60.0002

    


    Actually it supports below fps :

    


    fps=10.00,
fps=20.00,
fps=25.00,
fps=30.00,
fps=50.00,
fps=60.00


    


    How to guess and get the hidden list like : 20, 25, 30 and 50 ?
If I blindly make a list from guessed values,
Some format doesn't have fps=25 on the list and ffmpeg throw error !

    


    Note :
I can not use C++ or .NET to dig further.
Please suggest me some trick to get the proper list from ffmpeg commands only.
Or any universal guess !

  • How can ffmpeg be made as efficient as Android's built-in video viewer ?

    6 janvier 2016, par Nicholas

    I have a project based off of https://ikaruga2.wordpress.com/2011/06/15/video-live-wallpaper-part-1/, which uses an older copy of the ffmpeg libraries from http://bambuser.com/opensource. Within the C++ code in this project we have the following lines of code :

            unsigned long long current = GetCurrentTimeInNanoseconds();
    
        avcodec_decode_video(pCodecCtx, pFrame, &frameFinished, packet.data, packet.size);
    
        __android_log_print(ANDROID_LOG_DEBUG, "getFrame>>>>", "decode video time: %llu", (GetCurrentTimeInNanoseconds() - current)/1000000);

    This code continually reports between 60 and 90 ms to decode each frame on an Xperia Ion, using a 1280x720 h264 source video file. Other processing to get the frame out to the screen takes an average of 30ms more with very little variation. This leads to frame rates of 10-11fps.

    Ignoring that other processing, a decode that takes an average of 75ms would result in 13fps. However, when I browse my SD card and click on that mp4 file to open it in the native viewer, it shows at a full 30fps. Further, when I open a 1920x1080 version of the same mp4 in the native viewer it also runs at a full 30fps without stutter or lag. This implies (to my novice eye) that something is very very wrong, as the hardware is obviously capable of decoding many times faster.

    What flags or options can be passed to avcode_decode_video to optimize decode speed to match that of the native viewer ? Can optimizations be made elsewhere to optimize speed further ? Is there a reason that the native viewer can decode almost an order of magnitude faster (taking into account the 1920x1080 source results) ?

    EDIT

    The answer below is very helpful, but is not practical for me at this time. In the mean time I have managed to decrease decoding time by 70% with some optimal encoding flags found through many many hours of trial and error. Here are the ffmpeg arguments I’m using for encoding in case it helps anyone else who stumbles across this post :

            ffmpeg.exe -i "#inputFilePath#" -c:v libx264 -preset veryslow -g 2 -y -s 910x512 -b 5000k -minrate 2000k -maxrate 8000k -pix_fmt yuv420p -tune fastdecode -coder 0 -flags -loop -profile:v main -x264-params subme=5:ref=4 "#ouputFilePath#"

    With these settings ffmpeg is decoding frames in 20-25 seconds, though with the sws_scale and then writing out to the texture I’m still hovering at 22 FPS on an Xperia Ion at a lower resolution than I’d like.
