• Why my ffmpeg video encode codes does not work on other computer ?

  10 avril 2022, par Object Unknown

  I'm writing code to encode some cv::Mat images to a MP4 video. The program can run successfully in my computer which I developed it, but when I copied it (and all dlls it needs) to an other computer, it stopped work.

  


  The function which reporting error : (I got it from StackOverflow, and added some changes)

  Notes :

  


  


  callback is a function which prints error messsage and error code.

  
The error I recived is [uns::VideoWriter/Remux] Failed to write header to output file, error code: -22

• FFmpeg joined audio & video out of sync in some parts of the video

  20 septembre 2022, par ankur625

  I've developed a video joining service. Here is how it works in brief.

  


  Step 1 : Users upload their video (different video file types) from desktop/mobile. These videos are processed on the server, a logo is added, and converted to .mp4 format.

  


  Step 2 : All received mp4 files are then joined, a background music is added and saved.

  


  Everything is working as expected. The only problem is, when video files are joined. The final output video has audio out of sync in some parts. In step 2, I get "Non-monotonous DTS in output stream 0:1 ;" error message.

  


  Following are step 1 and step 2 codes.

  


  Step 1 :

  


  ffmpeg -y -i inputVideo -i inputImage -r 30000/1001 -video_track_timescale 30k -filter_complex "[0]scale=854:480:force_original_aspect_ratio=decrease,pad=854:480:(ow-iw)/2:(oh-ih)/2:black,setsar=1/1,setdar=16/9[v0];[1:v]format=argb,colorchannelmixer=aa=1.0,scale=71:72[overl1],[v0][overl1]overlay=297:285[v1]" -map "[v1]" -map 0:a -b:v 250k -maxrate 250k -bufsize 500k -crf 5 -preset slower -vbr 4 -movflags +faststart -b:a 96k -async 1 outputVideo.mp4


  


  Step 2 :

  


  ffmpeg -safe 0 -f concat -segment_time_metadata 1 -i videoList.txt -stream_loop -1 -i backgroundMusic.wav -filter_complex '[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.5[a0];[1:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=0.03[a1];[a0][a1]amerge=inputs=2[a]' -map 0:v -map '[a]' -c:v copy -ac 2 finalVideo.mp4


  


  I'm not expert with ffmpeg, and not sure, what's missing. can anyone help me fix this issue ?

  


  Step 2 (using amix suggested by kesh)

  


  ffmpeg -safe 0 -f concat -segment_time_metadata 1 -i list.txt -stream_loop -1 -i track1.mp3 -filter_complex "[0:a]volume=1.5[a0];[1:a]volume=0.03[a1];[a0][a1]amix=inputs=2:duration=first[a]" -map 0:v -map "[a]" -c:v copy -ac 2 out.mp4


  


  And, following is the full log of step 2,

• Transcode WEBM to RTMP

  7 avril 2024, par Justin White

  Summary

  


  My goal is to take a webcam stream from the browser and feed it into a program called Restreamer that takes in an RTMP stream.

  


  I've deduced that the browser Recording API produces Blobs that can be saved as WEBM.

  


  In order to stream the WEBM content to Restreamer I am attempting to use FFmpeg. I've read that forcing FLV format is required but otherwise all of the arguments are Greek to me. I've been unable to find a comparable topic where someone has tried to go from WEBM to RTMP. I have found examples of going the other direction, but reversing the FFmpeg command proved unfruitful.

  


  Saving to FLV works fine. Using the following command, I am able to transcode a WEBM file to FLV and play it on VLC :
  
ffmpeg -i ~/big-buck-bunny_trailer.webm -f flv out.flv

  


  However, if instead of outputting to a file I pass it to RTMP I get the following output :
  
ffmpeg -i ~/Downloads/big-buck-bunny_trailer.webm -f flv "rtmp://example.com/live"

  There are several interesting rabbit holes to follow here, but after following all of them I've come up with nothing.

  


  • HandShake: client signature does not match! :
  
More of a warning than an error, I assumed because I was going from "WEBM -> FLV" instead of the more traditional "MP4 -> FLV".

  


  • av_interleaved_write_frame(): Operation not permitted :
  
I found several issues on this. One of them calling it a storage issue, the other calling it a file permissions issue. I have plenty of disk space and have tried setting the input file to 777 permissions. However, the examples I've found on it being a file permissions issue all deal with outputting to a file rather than to an an RTMP IP.

  


  • Failed to update header with correct duration :
  
Advice I found was to add -flvflags no_duration_filesize to the command, which does suppress both "Failed to update..." errors, but does not fix the over-arching issue.

  


  What I've Tried

  


  • Multi-format transcoding

  


  MP4 to RTMP does work correctly :
  
ffmpeg -i ~/Downloads/big-buck-bunny_trailer.mp4 -f flv "rtmp://example.com/live"
  
Theoretically, I could stream the WEBM to a file, transcode that to an MP4 file, and then transcode that to FLV/RTMP. Sounds awful.

  


  • Pay for a service (Wowza, Flashphoner, api.video, etc)

  


  Unfortunately precisely what I am trying to avoid.

  


  • WebRTC to RTMP ?

  


  WebRTC seems to be a peer-to-peer connection and doesn't play nicely with a server/client scenario.

  


  • WebRTC to other ingest formats

  


  Restreamer also supports incoming streams of HLS, DASH, RTP, RTSP, RTMP, and SRT. However, these all seem to be examples of network sources that would be exposed via an IP URL. I am not sure that FFmpeg can do that.

  


  • Utilizing ffmpeg-wasm instead of CLI

  


  Available here, I thought that maybe by using a browser implementation I may get different results. But no. Not even an error to the console.

  


  • Streaming from OBS

  


  For the record, yes, I have tried streaming from OBS instead of going through FFmpeg and the Restreamer platform itself does work for normal use. I use it often.

  


  Post Script

  


  I've not been able to find any relevant solutions online. I am shocked that streaming from a browser webcam has not been solved 1000 times prior. This is related to a question made 7 years ago but it was not resolved and Flash is no longer an option.

  


  Recommendations

  


  • Adding -c:v libx264 -flags:v +global_header -c:a aac -ac 2 :
