Incomplete video when using ffmpeg to weave WAV and PNG
18 avril 2023, par Howard BaekI am trying to "weave" PNG image files with a WAV file. Here is the
ffmpeg
command that I used :

'/opt/homebrew/Cellar/ffmpeg/5.1.2_6/bin/ffmpeg' -y -f concat -safe 0 -i '/private/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T/Rtmp8gnKo7/ari_input_NQIg95oycVnb.txt' -i '/private/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T/Rtmp8gnKo7/ari_audio_ngNm5vr2vFta.wav' -c:v libx264 -c:a aac -ac 2 -shortest -fps_mode auto -pix_fmt yuv420p -vf fps=5,\"scale=trunc(iw/2)*2:trunc(ih/2)*2\" -strict experimental -max_muxing_queue_size 9999 -threads 2 '/var/folders/bb/m2b0ry595ys7bfs1r397lnf40000gp/T//Rtmp8gnKo7/file46521ffd4ef8.mp4'



While
ffmpeg
is doing its thing, I get this long message :

The output, a mp4 video file, isn't what I expected. I expected 6 PNG images embedded with my combined WAV file, but the video only shows 5 PNG images and a shortened WAV file.

I wanted to attach my WAV file and PNG files to make this question more reproducible, but couldn't so I'll redirect you to my GitHub issue, which contains 6 separate WAV files and 6 PNG files.

FFmpeg - Copy a (not A/V) data stream from input MP4 file [closed]
31 mars 2023, par darkshineI've got an
MP4
video file captured by DJI drone. The file contains the video stream (H.264) and also two data streams of unknown format. I would like to convert the video fromh.264
toh.265
and also save both of the included data streams. Unfortunately, I cannot force FFmpeg to copy the data streams across from the input file into the output file.

Here is the mp4 file :


ffprobe DJI_0019.MP4

Unsupported codec with id 0 for input stream 1
Unsupported codec with id 0 for input stream 2



I tried the command below :


ffmpeg -i DJI_0019.MP4 -map 0 -c:v libx265 -crf 25 -c:d copy -copy_unknown DJI_0019.v2.MP4


The command fails with the following error. The output file is empty.


[mp4 @ 0x556d0180ced0] Could not find tag for codec none in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --



Note that for "-c:d" option I tried different suggested values, none of them succeeded :


copy
none
bin
bin_data
data
null
file



In the meantime an attempt to save the data streams to separate files succeeds for the both of them with the commands :


ffmpeg -i DJI_0019.MP4 -map 0:d:0 -c copy -copy_unknown -f data DJI_0019.data0.bin


ffmpeg -i DJI_0019.MP4 -map 0:d:1 -c copy -copy_unknown -f data DJI_0019.data1.bin


Question :


How to force FFmpeg to copy the data streams from input to output ?
