  • FFmpeg : High pitched audio when converting AVI video to MP4 [closed]

    15 août 2023, par Karen S

    I'm pretty new to FFmpeg and I'm having trouble converting a video from AVI format to MP4. I'm trying to convert pcm_s16le to aac but the resulting audio is very high pitched and choppy.

    


    The AVI video has two audio streams :

    


    Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s
Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s


    


    In VLC Media Player the video plays fine and it uses the second audio stream.

    


    When I run ffmpeg -i input.avi -vcodec libx264 -crf 27 output.mp4 in my terminal, the output audio in the MP4 file sounds extremely choppy and the voices are chipmunk-like.
This is the codec information for the audio stream in VLC after the conversion :

    


    Codec: MPEG AAC Audio (mp4a)
Type: Audio
Channels: Stereo
Sample rate: 48000 Hz
Bits per sample: 32


    


    This is the terminal output :

    FFmpeg automatically selects the first audio stream to encode but then this error comes up :

    


    [pcm_s16le @ 000001d1b0696680] This decoder does not support parameter changes, but PARAM_CHANGE side data was sent to it.


    


    To bypass this error, I've edited the FFmpeg command so that the second stream is selected instead for aac encoding, but then the resulting MP4 video is silent.

    


    Does anyone know why FFmpeg is unable to convert the original AVI audio to aac without it sounding higher-pitched ? I think that the sample rate of the first stream might be set incorrectly but I'm not too sure how to fix it so that the encoder reads it properly.

    


  • ffmpeg autorotate results in broken output when moving from cpu to gpu

    16 août 2023, par user2290269

    Given an input file with a Display Matrix :

    


    ffprobe -show_format -show_streams -print_format json -i rotated.mov

    


    Using CPU-transcoding is resulting in a correctly rotated output file and exitcode 0 :

    


    ffmpeg -autorotate 1 -y -i rotated.mov -f mp4 -vf scale=-2:360 -c:v libx264 -b:v 800K cpu.mp4

    


    Using GPU-transcoding is resulting in a incorretly rotated output file and exitcode 0 :

    


    ffmpeg -hwaccel cuda -hwaccel_output_format cuda -autorotate 1 -y -i rotated.mov -f mp4 -vf scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu.mp4

    


    See the Display Matrix rotation information.
The GPU-File plays upside down, the CPU-File plays correctly.

    


    Looks like (the default -autoroatate 1) is silently ignored for GPU-based transcoding. automatic insertion of filters fails silently. exitcode is 0 for gpu, too. but the output is actually broken, because it is upside down in playback.

    


    Same is true for input having other rotations than -180°.

    


    One (bad) way to solve, use complex filters :
When using complex filter with hwupload_cuda, the autorotate-filters get added correctly automatically.

    


    ffmpeg -y -i rotated.mov -f mp4 -vf hwupload_cuda=device=0,scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu-complexfilter.mp4

    


    When going into scale_cuda directly there is an error message and exitcode !=0.

    


    ffmpeg -y -loglevel debug -i rotated.mov -f mp4 -vf scale_cuda=-2:360 -c:v h264_nvenc -b:v 800K gpu-error.mp4

    


    Impossible to convert between the formats supported by the filter 'hflip' and the filter 'auto_scale_0'
[vf#0:0 @ 0000026723318540] Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while filtering: Function not implemented


    


    Using complex filters is not a good solution, because it disables automatic filter graph filter-adding and -mapping, which is very useful for e.g. -f HLS.

    


    So is there a way to keep complex filters away and get correct output or exitcode !=0 indicating a broken output for any given input-file coming as a file-upload from the internet ?

  • FFMPEG Pipeline Crash [closed]

    17 août 2023, par Badgio10177

    I instantiate an ffmpeg pipeline within C++. No frames get streamed to the RTSP server and the pipeline crashes unexpectedly.

    


    I have the following code :

    


    #include <iostream>&#xA;#include <typeinfo>&#xA;#include "opencvmex.hpp"&#xA;#include &#xA;#include &#xA;#include "mex.h"&#xA;#include &#xA;#include &#xA;#include  // Windows API for process enumeration&#xA;#include <opencv2></opencv2>core.hpp>&#xA;&#xA;// Global variables&#xA;FILE* openPipeLine = NULL;&#xA;&#xA;//////////////////////////////////////////////////////////////////////////////&#xA;// Exit function to execute when the mex function is cleared.&#xA;//////////////////////////////////////////////////////////////////////////////&#xA;void exitFcn()&#xA;{&#xA;    fflush(openPipeLine); // Clear out the pipeline.&#xA;    _pclose(openPipeLine);   //Close the pipeline.&#xA;}&#xA;&#xA;///////////////////////////////////////////////////////////////////////////&#xA;// Main entry point to a MEX function&#xA;///////////////////////////////////////////////////////////////////////////&#xA;void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[], int frameWidth, int frameHeight)&#xA;{&#xA;    // Use the appropriate namespace for OpenCV functions&#xA;    using namespace cv;&#xA;&#xA;    Ptr<mat> inputFrame = ocvMxArrayToImage_uint8(prhs[0], true);&#xA;    Mat processedFrame = *inputFrame;&#xA;&#xA;    // Check if FFMPEG process has been started&#xA;    if (!openPipeLine)&#xA;    {&#xA;        openPipeLine = _popen("ffmpeg -f rawvideo -r 10 -video_size 1280x720 -pixel_format bgr24 -i pipe: -vcodec libx264 -crf 25 -pix_fmt yuv420p -f rtsp rtsp://192.168.0.2:8554/mystream 2> log.txt", "wb");&#xA;    }&#xA;&#xA;    // Write the frame data to the pipeline&#xA;    fwrite(processedFrame.data, 1, frameWidth * frameHeight * 3, openPipeLine);&#xA;    mexAtExit(exitFcn);&#xA;}&#xA;&#xA;&#xA;&#xA;</mat></typeinfo></iostream>

    &#xA;

    The function is a Matlab Mex function. What is interesting is that there are certain times when the stream works and some times it just crashes. The log file for the ffmpeg process is the following :

    Are there any parameters in my pipeline that are causing the process to crash ?
