• ffmpeg crashes with "Internal bug", "Failed to inject frame into filter network" while trying to convert PNG files into an animated gif using filters

  12 août 2022, par EigentlichOracler

  ffmpeg version : ffmpeg version 4.2.7-0ubuntu0.1

  


  Kernel : 5.4.0-122-lowlatency #138-Ubuntu SMP PREEMPT x86_64 x86_64 x86_64 GNU/Linux

  


  PNG-Images : 996 pieces, all equal in size : 1000x50

  


  Then trying to build palette using palettegen :

  


  export filters="scale=1000:-1:flags=lanczos"
export palette=./stripes_palette.png
ffmpeg -v warning -i ./palette_source_stripes.png -vf "$filters,palettegen=stats_mode=diff" -y $palette
[Parsed_palettegen_1 @ 0x55f0eea30e00] Dupped color: FF63000D


  


  Palette file has been created, looks good so far. Then I tried to convert all 996 PNG files into one single (space optimized) animated GIF file using paletteuse :

  


  ffmpeg -v warning -framerate 5 -thread_queue_size 2048 -i ./tmp/temp.%04d.png -i $palette -lavfi "$filters,paletteuse=dither=bayer:bayer_scale=5:diff_mode=rectangle" -r 5 -loop -1 -y testanim.gif
Error while filtering: Internal bug, should not have happened
Failed to inject frame into filter network: Internal bug, should not have happened
Error while processing the decoded data for stream #0:0


  


  The reason for "-framerate 5" for the input and "-r 5" for the output is : I wanted the animated GIF to use a determined time for running through animation. It already had worked out without using complex filtering, but the results were huge GIF files which are hard to handle.
But even when I avoid both framerate parameters, still the same error message occurs.

  


  Should I look deeper into the "Dupped color" which has been mentioned ? Did anybody encounter a similar issue using ffmpeg ?
I'm not used to deal with filters (nor "complex filters") in ffmpeg, I'm very new at this, but I've found no tips regarding an ffmpeg crash like I've right here.

  Same error occurs with current stable version

• How to decode two Dolby E audio streams simultaneously with ffmpeg ?

  11 août 2022, par David

  I'm trying to decode 2 Dolby-E audio streams simultaneously.

  


  ffmpeg -non_pcm_mode copy -i C:\vlc-record.ts -map 0:3 -map 0:4 -c:a pcm_s24le -f s24le - | ffplay -

  


  Using -map 0:3 it works for one at a time but when I add the second one -map 0:4 it only process the first one and there is just one stream on my dolby_e output pipe.

  


  Is there a way to create a two streams multicanal non-pcm output from 2 Dolbys PCM streams ?

  


  I tried to find a solution with named pipe but it seems like windows command line doesn't accept this. I also tried to merge the PCM streams but then it says Invalid data found when processing input.

  


  I can't make it with 2 pass because I'll be using it with udp live video streams.
