  • Discard data stream from container using ffmpeg

    10 décembre 2020, par A.Be

    I am trying to get rid of a data (subtitle) stream within a Mp4 container, using ffmpeg.

    



    Here's the screenshot from ffprobe :

    I tried :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4


    



    Data track still there, just moved from stream 0 to stream 2

    



    I tried also :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4


    



    Same result, track still there, just jumped to stream 0:2 no luck.

    



    Any hint ?
Thanks in advance

    


  • How to get rid of errors "jitter buffer full" in ffmpeg ?

    31 janvier 2021, par jidckii

    How to get rid of errors jitter buffer full ?
    
I use ffmpeg from one of the latest snapshots.
    
ffmpeg version N-90078-gf611fef Copyright (c) 2000-2018 the FFmpeg developers

    



    The problem is that from the camera on rtsp there is such a stream :
    
http://ibb.co/fmckCc
    
It is not possible to fix this from the camera side.

    



    I accept it like this :

    



    ffmpeg \
-strict experimental \
-fflags + genpts \
-fflags + latm \
-seek2any 1 \
-avoid_negative_ts + make_zero \
-max_delay 5000000 \
-rtsp_transport udp \
-i rtsp: // admin: @ 192.168.87.21: 554/0? .sdp \
-map 0 \
-r 15 \
-c: v copy \
-an \
-f mpegts udp: //239.0.0.1: 1234? ttl = 1? pkt_size = 1316


    



    I later start to get errors from time to time

    



    [rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 2 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 4 packets


    



    because of this the picture crumbles.

    



    I increased the udp buffer in the linux kernel settings :

    



    net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.udp_mem = 8388608 12582912 16777216
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 65536 8388608


    



    It did not solve my problem.
    
Tell me, how can you deal with such errors ?

    


  • Adding cover art to video wtih chapters and chapters getting deleted

    31 mai 2021, par throwaway513

    I am trying to add a cover art to a video with chapters.

    


    I added 2 chapters to a video using :

    


    ffmpeg -i 1.mp4 -i Chapters.txt -map_metadata 1 -c copy 2.mp4

    


    but when I try to add cover art it deletes the first chapter and only keeps the second ?

    


    ffmpeg -i 2.mp4 -i image.jpg -map 1 -map 0 -c copy -disposition:0 attached_pic 3.mp4

    


    I also tried mp3tag but the picture doesn't show on the file after adding chapters through ffmpeg. Chapters work fine on 2.mp4 but on 3.mp4 it deletes the first chapter. It also deletes the chapter when I do ffmpeg -i 2.mp4 -c copy any.mp4
