• Trying to convert an RTSP stream to a HSL file, but get a "Failed to Open Segment" error

  1er juin 2021, par Alvydas Juodikis

  These are the linux commands I ran on ubuntu 20.04 to convert an rtsp stream to a HLS file. I was trying to then display it onto my html webserver to run a live video but I'm stuck at an error.

  


  ffmpeg -fflags nobuffer \&#xA; -rtsp_transport tcp \&#xA; -i <my rtsp="rtsp" url="url"> \&#xA; -vsync 0 \&#xA; -copyts \&#xA; -vcodec copy \&#xA; -movflags frag_keyframe&#x2B;empty_moov \&#xA; -an \&#xA; -hls_flags delete_segments&#x2B;append_list \&#xA; -f segment \&#xA; -segment_list_flags live \&#xA; -segment_time 0.5 \&#xA; -segment_list_size 1 \&#xA; -segment_format mpegts \&#xA; -segment_list Home/Desktop/fmpegsolution/index.m3u8 \&#xA; -segment_list_type m3u8 \&#xA; -segment_list_entry_prefix Home/Desktop/fmpegsolution/ \&#xA; Home/Desktop/fmpegsolution/%3d.ts&#xA;</my>

  


  I'm using an example from this link :
https://girishjoshi.io/post/ffmpeg-rtsp-to-hls/

  


  I try to generate my file into a directory located in my desktop called fmpegsolution (hence the output path Home/Desktop/fmpegsolution)

  


  The error :

  


  When running this on terminal, the error comes out to :
[segment @ 0x558c82e11ec0] Opening 'Home/Desktop/fmpegsolution/000.ts' for writing [segment @ 0x558c82e11ec0] Failed to open segment 'Home/Desktop/fmpegsolution/000.ts' Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

  


  My issue is related to the folder or directory but it definitely exists. I even tried creating a "%3d.ts" blank file (000.ts) but that had no effect. Could use some help. Thanks for your time.

  Tried the solutions from these links but they didn't work :

  If anyone has any idea how to fix it, or needs any more information, please let me know.

  


• Getting this error using ffmpeg concat in ReactNative "concat imposible to open"

  2 février 2021, par Josip Bogdan

  Hy, I am trying to concat multyple video using ffmpeg concat, testing on samsung j76, android version 8.1.0

  


  const textFile = await (await writeTextFileWithAllVideoFiles(filePaths))  
const outputPath = Platform.OS === 'ios' ? `${RNFS.DocumentDirectoryPath}/video-1.mp4` : `${RNFS.DocumentDirectoryPath}/video-1.mp4`
console.log(`-f concat -safe 0 -i ${textFile} -c copy ${outputPath}`)
const result = await RNFFmpeg.execute(`-f concat -safe 0 -i ${textFile} -c copy ${outputPath}`)


  


  And here is how I create the txt file

  


  const writeTextFileWithAllVideoFiles = async (filePaths) => {
var RNFS = require('react-native-fs');
var path = RNFS.DocumentDirectoryPath + '/videoList.txt';

var fileContent = ''
console.log("fileplay1");
filePaths.forEach(path => {
   fileContent += 'file ' + '\'' + path.substring(8) + '\'' + '\r\n'
});
console.log(fileContent);
return RNFS.writeFile(path, fileContent, 'utf8')
.then((success) => {
   console.log(path)
   if (RNFS.exists(path))
      console.log('FILE WRITTEN!')
   return path
})
.catch((err) => {
    console.log(err.message)
    return err.message
});  
}


  


  This is my console log output

  And the txt file is not on my android device
My manifest is like this
