    I have skipped few lines of output as there are many frames. So if you see at the end of output on both A and B sides and look at the number of I, P and B frames,the number of P and B frames on receiver B is more than that at sender A. Can anyone please tell me why there is a change in the number of frames ?

  • How to fix ffmpeg complex filters "Invalid stream specifier" [duplicate]

    15 mai 2019, par Chase

    This question already has an answer here :

    I’m attempting to scale and blur (sections of) a video with ffmpeg complex filters. This has actually been working in production for years.

    I’m now running a newer build of ffmpeg on Ubuntu 18.04 and getting an error relating to the filters where the same command works fine on Ubuntu 16.04’s ffmpeg against the same video.


    Specifically, I’m seeing the following error :

    mov,mp4,m4a,3gp,3g2,mj2 @ 0x56055a5902c0] Invalid stream specifier: vs0.
    
    Last message repeated 1 times
    
Stream specifier 'vs0' in filtergraph description ... matches no streams.

    Has something about the complex filter API changed that would make this same input invalid in a newer version of ffmpeg ?

    The command in question is just running the following in a Bash terminal.

    ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

    If we break up the complex filter statement, it looks like :

    [0:v]scale=-2:'min(320,ih)'[vs0];
    
[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];
    
[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];
    
[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];
    
[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];
    
[ovr1][b2]overlay=main_w/9:0[vs1]

    On ffmpeg version N-86980-g62b7553 (Ubuntu 16.04), everything works great as it has done for years.

    $ ffmpeg -ss 60 -i ~/test.mp4 -y -filter_complex "[0:v]scale=-2:'min(320,ih)'[vs0];[vs0]crop=in_w/9:in_h/2:0:0,boxblur=5:1:cr=3:ar=3[b0];[vs0]crop=in_w/9:in_h/2:in_w-out_w:0,boxblur=5:1:cr=3:ar=3[b1];[vs0]crop=(in_w-2*in_w/9):in_h/20:in_w/9:0,boxblur=5:1:cr=3:ar=3[b2];[vs0][b0]overlay=0:0[ovr0];[ovr0][b1]overlay=main_w-overlay_w:0[ovr1];[ovr1][b2]overlay=main_w/9:0[vs1]" -map [vs1] -an -ac 2 -b:a 128k -acodec aac -b:v 1024k -r 30 -vcodec libx264 -t 300 -y -preset slow -movflags faststart -pix_fmt yuv420p -f mp4 ~/out.mp4

  • FFmpeg remux rtp to mpegts [on hold]

    16 décembre 2013, par Ardoramor

    I am trying to remux rtp stream into mptegts format. I have an SDP file with the following contents :

    v=0
    
o=- 0 0 IN IP4 127.0.0.1

a=control:trackID=1

    I execute the following ffmpeg command :

    ffmpeg -i "test.sdp" -f mpegts -vcodec copy "/tmp/test.ts"

    And I get the following information :

Stream mapping:
    
  Stream #0.0 -> #0.0

    I receive the following error :

    So I add the suggested bitstream filter :

    ffmpeg -i "test.sdp" -f mpegts -vbsf h264_mp4toannexb "/tmp/test.ts"

    But the h264 encoding now becomes h262 (mpeg2video) :

    ~$ffprobe /tmp/test.ts
    
Input #0, mpegts, from '/tmp/test.ts':

    Is there any way to keep the h264 codec without re-encoding it ? Doing so becomes very CPU intensive.

    Update

    Hopefully this will clear up the issue and remove the off-topic stamp.

    I'm writing an Android app that is based off of SpyDroids streaming architecture. The app communicates with the server, providing it the SDP. The server spawns an ffmpeg process to remux the incoming video stream into mpegts and broadcasts it on multicast (right now just file).

    SpyDroid performs streaming by sending recorded mp4 file through localsocket, received h264 packets, supposedly (according to code removed mp4 h264 prefix [annexb]), wraps it with rtp headrs and sends it on its way. Thus, the RPT stream I get is clearly not originally generated as such.

    As @Wagner Patriota has mentioned, I should add '-vcodec copy'. I had run the remuxing with it before as well but the error is still present (full output) :

    ~$ffmpeg -i "test.sdp" -f mpegts -vcodec copy -vbsf h264_mp4toannexb "/tmp/test.ts"

av_interleaved_write_frame(): Operation not permitted

    The error reports that the invalid argument has been supplied. Increased loglevel does not give any more information. I know that ffmpeg is sometimes finicky with argument order. However, they seen to be in order of documentation as well as suggested order by @Wagner Patriota.
