• How to combine multiple videos in android using ffmpeg ?

  23 mai 2023, par Haeiny

  I added dependency to use ffmpeg on Android.

  


  implementation "com.arthenica:mobile-ffmpeg-full:4.4"


  


  And I wanted to combine the videos from the gallery, so I temporarily saved the imported video in the cache directory in the app.

  


  After that, I wrote the following function to take the saved images and merge them using ffmpeg :

  


  
fun mergeVideos(videoPaths: List\): Int {
        val cacheDirectory = this.externalCacheDir
        mergedVideoFile = File(cacheDirectory, "merged_video.mp4").absolutePath

        val command = StringBuilder()
        command.append("ffmpeg")
        for (videoPath in videoPaths) {
            command.append(" -i ").append(videoPath)
        }

        command.append(" -filter_complex ").append("\"")
        for (i in videoPaths.indices) {
            command.append("[$i:v] ").append("[$i:a] ")
        }

        command.append("concat=n=").append(videoPaths.size).append(":v=1:a=1 [v] [a]").append("\"")
        command.append(" -map \"[v]\" -map \"[a]\" ").append(mergedVideoFile)
    
        return FFmpeg.execute(command.toString())
    }


  


  I wanted to temporarily save the merged video in the "mergedVideoFile" so that I could save them in the cache directory, and videoPaths would get the Urls of the videos I wanted to merge into the list.

  


  The command verified through Log.d :

  


  
ffmpeg -i /storage/emulated/0/Android/data/"project name"/files/Movies/VIDEO1.mp4 -i /storage/emulated/0/Android/data/"project name"/files/Movies/VIDEO2.mp4 -filter_complex "\[0:v\] \[0:a\] \[1:v\] \[1:a\] concat=n=2:v=1:a=1 \[v\] \[a\]" -map "\[v\]" -map "\[a\]" /storage/emulated/0/Android/data/"project name"/cache/merged_video.mp4

• Discord Music Bot interrupts music playback on Heroku

  29 mars 2023, par denisnumb

  I have a music discord bot written in Python. Bot plays music from YouTube using the yt-dlp library and ffmpeg.

  


  Everything worked fine, but a couple of days ago the bot began to interrupt the playback of any tracks for ~80% duration, crashing with an error :

  


  [tls @ 0x6e3b440] Error in the pull function.
[tls @ 0x6e3b440] IO error: Connection reset by peer
[https @ 0x6e37900] Will reconnect at 720896 in 0 second(s), error=Connection reset by peer.


  


  I have the latest version of py-cord=2.4.1 and yt-dlp==2023.3.4 installed. When the bot is launched on my computer, the bot plays all the tracks to the end, so the problem is clearly not in the code and not in the libraries.

  


  I suspect something is wrong with ffmpeg, so I tried installing different buildpacks, but that didn't solve the problem.

  


  At the moment I have the following installed :

  


  https://github.com/xrisk/heroku-opus.git
https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git


  


  What could be the problem and how to solve it ? Why did this problem appear only on hosting ? Why didn't this happen before ?
