• FFMPEG to command not working as i intend [closed]

  11 mai 2023, par KillerHaseTV

  I want to cut my video by using timestamps. I have a txt file with my timestamps and I put them in the correct variables. For example, $startzeit = 00:00:01 and $endzeit = 00:00:10. So, I want :01 -> :10 and not :01 and run for 10 seconds until :11.

  


  The problem has something to do with "-to" because the timestamps are correct.

  


  Here is my code

  


  $segment = 0
$pathtxt = "D:\Streamshit\Stream\Videos schneiden\timestamps.txt"
$pathvideo = "D:\Streamshit\Stream\Videos schneiden\2023-05-04_18-59-45.mkv"
$zeile = (Get-Content -LiteralPath $pathtxt).Length
$segment_list = @(Get-Content -LiteralPath $Pathtxt)

while($segment -lt $zeile){

    $timestamp = $segment_list[$segment].split(",")
    $startzeit = $timestamp[0]
    $endzeit = $timestamp[1]
    $TEST = "D:\Streamshit\Stream\Videos schneiden\Clips\video$segment.mp4"
    $segment++    
    ffmpeg -ss $startzeit -i $pathvideo -to $endzeit -c copy $TEST 
}


  


  and here are my timestamps :

  


  00:00:01,00:00:10
00:00:24,00:00:41
00:01:29,00:01:42
00:02:19,00:02:46
00:04:11,00:04:58
00:08:38,00:08:42
00:10:05,00:10:14
00:12:07,00:14:47
00:16:59,00:17:20
00:26:31,00:27:00
00:34:36,00:36:56
00:39:01,00:39:21
00:46:32,00:46:53
00:48:00,00:48:58
00:51:11,00:52:01
00:56:15,00:57:52
00:59:20,01:01:20
01:03:21,01:03:40
01:12:02,01:12:17
01:14:48,01:14:59
01:15:13,01:19:03
01:19:14,01:19:23
01:23:49,01:24:06
01:24:23,01:24:50
01:25:13,01:26:10
01:26:45,01:26:56
01:29:08,01:29:29
01:31:54,01:32:10
01:36:32,01:37:41
01:39:37,01:39:53
01:55:30,01:56:02
02:13:07,02:13:44
03:12:19,03:12:50


  


  I already tried it with just -t which is normally doing what my code is doing and -to should do what I want, but it doesn't.

  


• App crashes on Google TV when playing MP4 videos

  14 avril 2023, par fab

  I am having problems with an Android app that was developed for me. The issue occurs when playing MP4 videos ; the app plays them correctly, but at some point, the app crashes and exits. I have been reviewing errors using Android Studio, and the only error that appears is the following :

  One clarification is that the app is built with IONIC and Angular.

  


  The FFMPEG code that converts the video in golang is as follows :

  


  func ConvertVideoFile(inputFileName, outputFileName string) error { err := ffmpeg_go.Input(inputFileName). Filter("scale", ffmpeg_go.Args{"800:600"}). Output(outputFileName, ffmpeg_go.KwArgs{ "c:v": "libx264", "profile:v": "high", "level": "3.1", "pix_fmt": "yuv420p", "preset": "medium", "crf": "23", "b:v": "782k", "r": "25", "c:a": "aac", "b:a": "2k", "ar": "48000", "movflags": "+faststart", "max_muxing_queue_size": "1024", }, ). OverWriteOutput().ErrorToStdOut().Run() return err }

  


  Remove this error 2023-04-14 00:45:45.848 7221-7654 ACodec com.app.X E [OMX.amlogic.avc.decoder.awesome2

  


• Trying to stream a video loop using FFMPEG. However, I keep getting the error "Cannot Write the Headers Server returned 400 Bad Request" [closed]

  8 mai 2023, par lokit khemka

  I am using mediamtx for starting RTSP server. The command that I am using for ffmpeg is as follows :

  


  ffmpeg -re -stream_loop -1 -i ./clouds.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554

  


  The tried various different options but not luck. I am not getting the ffmpeg to stream the video.

  


  The file details are as follows :
