  • What is a decode_slice_header error ? Can this error output be solved ?

    21 septembre 2017, par Santiago Nicolas Martin

    While trying to decode or even get any useful information about .mts file, using in this case this command :

    ffmpeg -i URL

    I am always getting these errors :

    [h264 @ 0xb4c080] non-existing SPS 0 referenced in buffering period
    
[h264 @ 0xb4c080] non-existing PPS 0 referenced
    
[h264 @ 0xb4c080] non-existing SPS 0 referenced in buffering period
    
[h264 @ 0xb4c080] non-existing PPS 0 referenced
    
[h264 @ 0xb4c080] decode_slice_header error
    
[h264 @ 0xb4c080] no frame!

    Is there a way to fix it ? The program after all these errors continues processing but the output doesn’t work. Is there a problem with the file itself ?

  • Dash timestamp : 41390056 is out of range for mov/mp4 format

    26 octobre 2017, par mike

    I’m trying to convert a aac stream to dash. The issue is that I get a lot of errors as below(though it seems to segment it into multiple files but I get errors on the player too). The question is why do I get these errors and how can I fix it ? If I simply convert "copy" it into to a single mp4 file it works without error.

        ffmpeg -i  "a.mkv" -y -map  0:1 -c:0 copy -min_seg_duration 1000000 
    
-use_timeline 1 -use_template 1 -init_seg_name init.mp4s 
    
-media_seg_name  "\$Number\$.mp4s" -adaptation_sets "id=1,streams=0"
    
-remove_at_exit 0  -f dash -dash 1 
    
"out/stream.mpd" -loglevel error

    Output

    [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40475608 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40764376 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40860664 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41149432 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41390056 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41823208 is out of range for mov/mp4 format

    Copy to a single MP4 works just fine
    ffmpeg -i "a.mkv" -y -map 0:1 -c:0 copy -f mp4 -dash 1 "out/out.mp4" -loglevel error
