  • Mp4 render result from ffmpeg not playable on android

    11 juillet 2019, par albert

    I’m using PHP to run ffmpeg(4.0.2) render out MP4 file.
    MP4 file playable on all of iOS device, and most laptop, but not playable on android device.

    Here is the ffmpeg code I use to render the video

    /usr/local/bin/ffmpeg -filter_complex "[0]reverse[r];[0][r]concat, loop=1:65, setpts=N/15/TB" -r 15 -f image2 -i /Source/0001_CAM%02d.jpg -c:v libx264 -preset fast -crf 19 -profile:v baseline -movflags +faststart -pix_fmt yuv420p /Result/output.mp4

    Here is the log

  • Inputing a List of Files for Concatenation with Node.js Module fluent-ffmpeg

    26 juin 2018, par carpiediem

    Version information

    • fluent-ffmpeg version : 2.1.2
    • ffmpeg version : 3.4.2
    • OS : Windows 10

    Code to reproduce

    ffmpeg('C:/path/to/list.txt').mergeToFile('C:/path/to/out.mp4', 'C:/path/to/temp');

    list.txt :

    file 'C:/path/to/chunk01.ts'
    
file 'C:/path/to/chunk02.ts'
    
file 'C:/path/to/chunk03.ts'
    
file 'C:/path/to/chunk04.ts'

    Note : I’ve tried both absolute and relative paths, with the same result.

    Expected results

    A video file at C:/path/to/out.mp4 that matches the 4 files in list.txt, concatenated end-to-end.

    Observed results

    An empty file at C:/path/to/out.mp4 with 0 duration and only 15kB in size. No errors were thrown.

    This is the command that I’m trying to duplicate (it works as expected, with relative paths in list.txt) :

    C:/path/to> ffmpeg -f concat -i list.txt -c copy out.ts

    stdout & stderr

    stdout was empty. stderr is copied below (with file names modified to match the ones above) :

  • FFmpeg pipe input, error while transcoding from WebM to MP4

    7 mai 2022, par saurav

    I am trying to record a video from pipe input using FFMPEG. The pipe input is in WebM format i.e. the video codec is VP8 and the audio codec is OPUS. I am able to save the output video in the WebM format using FFMPEG without any issue. But when I am trying to save it in MP4 format, I am not getting the desired output. Though there are no errors while saving, the output file shows an error with description " This file contains no playable streams !."

    


    These are the options for successfully recording in the WebM format.

    


        '-loglevel', 'debug', '-protocol_whitelist', 'pipe,udp,rtp', 
'-fflags', '+genpts', '-i', 'pipe:0', '-map', '0:v:0', '-c:v', 
'copy', '-map', '0:a:0', '-strict', '-2', '-c:a', 'copy', '-flags',
 '+global_header', '-f', 'webm', 'output.webm'


    


    Here are my ffmpeg options for recording in the MP4 format.

    


        '-thread_queue_size', '4096', '-r', '25', '-i', 'pipe:0', 
    '-c:v', 'libx264', '-preset', 'veryFast', '-pix_fmt', 'yuvj420p', 
    '-acodec', 'aac', "output.mp4"

    I have a doubt on this output as it may have been causing the issue.

    


    ffmpeg::process::data [data:'[swscaler @ 0x55a63050ddc0] deprecated
 pixel format used, make sure you did set range correctly\n'] +23ms


    


    I hope I have provided enough information about the issue I am facing. Please ask for any other information needed to understand the issue correctly.

    


    I am sure that I am missing some ffmpeg options which is causing this issue. But I am not able to identify them ! Any help in correcting this issue would be greatly appreciated.

    


    Thank you.
