• FFmpeg - Copy a (not A/V) data stream from input MP4 file [closed]

  31 mars 2023, par darkshine

  I'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 from h.264 to h.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

  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

  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 ?

• FFmpeg c api create encoder for AV_CODEC_ID_H264 crash on Windows

  30 avril 2023, par Guanyuming He

  I'm using ffmpeg (version 5.1.2) to clip a mp4 video per frame so I need to decode and encode it. However, when I'm creating the encoder for its video stream, the program always crashes at the call to avio_open2(), after H264 gives this error message :

  


  [h264_mf @ 0000025C1EBC1900] could not set output type (80004005)


  


  

  


  The configuration (time_base, pix_fmt, width, height) of the codec context of the encoder is copied from the decoder, and I checked if the pixel format is supported by finding if it's in codec->pix_fmts.

  


  I find that the problem does not involve all my other pieces of code, because this minimal program can duplicate the same problem :

  


  extern "C"&#xA;{&#xA;#include <libavcodec></libavcodec>avcodec.h>&#xA;}&#xA;&#xA;int main()&#xA;{&#xA;    auto codec = avcodec_find_encoder(AV_CODEC_ID_H264);&#xA;    auto codec_ctx = avcodec_alloc_context3(codec);&#xA;&#xA;    codec_ctx->pix_fmt = AV_PIX_FMT_YUV420P;&#xA;    codec_ctx->width = 2560;&#xA;    codec_ctx->height = 1440;&#xA;    codec_ctx->time_base.num = 1; codec_ctx->time_base.den = 180000;&#xA;&#xA;    avcodec_open2(codec_ctx, codec, NULL);&#xA;&#xA;    return 0;&#xA;}&#xA;

  


  Then I suspect if it's a bug of ffmpeg. My environment is Windows 11 64-bit, Visual Studio 2022. The ffmpeg library is obtained from vcpkg, as shown in the following image :
