• How to use FFmpeg to live HLS stream with subtitle ?

  17 août 2023, par iHad 169

  I want to use FFmpeg to live HLS stream with subtitle.
I have a Media. The Media have one video track, two audio track, four subtitle.
But, I tryed this command :

  



  ffmpeg -i input0.mkv \
-map 0:v:0 -c:v libx264 -strict -2 -s 426x240   -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename video/videoTrack240p_%d.ts      video/videoTrack240p.m3u8 \
-map 0:v:0 -c:v libx264 -strict -2 -s 1280x720  -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename video/videoTrack720p_%d.ts      video/videoTrack720p.m3u8 \
-map 0:v:0 -c:v libx264 -strict -2 -s 1920x1080 -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename video/videoTrack1080p_%d.ts     video/videoTrack1080p.m3u8 \
-map 0:a:0 -c:a aac                             -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename audio/audioTrack1_%d.aac        audio/audioTrack0.m3u8 \
-map 0:a:1 -c:a aac                             -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename audio/audioTrack0_%d.aac        audio/audioTrack1.m3u8 \

-map 0:s:1 -c:s webvtt                          -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename subtitle/subtitleTrack1_%d.vtt  subtitle/subtitleTrack1.m3u8 \
-map 0:s:2 -c:s webvtt                          -f hls -hls_time 10 -hls_list_size 6 -hls_wrap 10 -hls_segment_filename subtitle/subtitleTrack2_%d.vtt  subtitle/subtitleTrack2.m3u8 \

  It show this Error :

  The first part of my script that asks whether to check for cinavia doesn’t work. That is, if I type in ’y’ or ’Y’ it doesn’t proceed to the CNVIACHk function but goes instead to the MVIEPARAMs function.

• RUN FFMPEG IN PYTHON

  7 janvier 2023, par SMART

  I have 1 video & 1 audio.

  


  video's duration : 4s

  


  audio's duration : 7.48 s

  


  i wrote python function to combine these files

  


  MY CODE :

  


   import subprocess as sp

    def runffmpeg(cmd):
        try:
            pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
                            universal_newlines=True)
    
            ffmpeg_output, _ = pipe.communicate()
    
            print(ffmpeg_output)
            return (ffmpeg_output)
    
        except sp.CalledProcessError as err:
            print("FFmpeg stdout output on error:\n" + err.output)
    
    def get_duration(fn):
        cmd = (
            f"ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 {fn}")
    
        cmd1 = (
            f"ffprobe -v error -of flat=s_ -select_streams 1 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1 {fn}")
        try:
            pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
                            universal_newlines=True)
    
            viddur, _ = pipe.communicate()
    
            print(viddur)
    
            pipe = sp.Popen(cmd1, stdout=sp.PIPE, stderr=sp.STDOUT,
                            universal_newlines=True)
    
            auddur, _ = pipe.communicate()
    
            try:
                auddur = float(auddur.strip())
            except:
                auddur = 0
    
            print(auddur)
    
            # if (len(auddur) == 0):
            #     auddur = 0
    
            return float(viddur.strip()), (auddur)
    
        except sp.CalledProcessError as err:
            print("FFmpeg stdout output on error:\n" + err.output)
    

def set_audio_to_video(vn, an, output):

    vdur, adur = get_duration(fn=vn)
    print(f" video duration is  {vdur}")

    auddur, adur = get_duration(fn=an)
    print(f" audio duration is  {auddur}")

   #cmd = (f" ffmpeg -i {vn} -i {an} -filter_complex \"[0:v]setpts=PTS*{auddur}/{vdur}     [v];atempo={auddur}/{vdur} [a]\" -map \"[v]\" -map 1:a -shortest -y {output}")

cmd = (
    f" ffmpeg -i {vn} -i {an} -filter_complex \"[0:v]setpts=PTS*{auddur}/{vdur} [v]\" -map \"[v]\" -map 1:a -shortest -pix_fmt yuv420p -y {output}")
print(cmd)

x = runffmpeg(cmd=cmd)


  


  to call the function :
set_audio_to_video(vn="cremovie.mp4", an="a1.wav", output="output.mp4")

  


  i'm getting error :

  


      Traceback (most recent call last):&#xA;      File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 439, in <module>&#xA;    set_audio_to_video(vn="cremovie.mp4", an="a1.wav", output="output.mp4")&#xA;      File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 424, in set_audio_to_video&#xA;    x = runffmpeg(cmd=cmd)&#xA;  File "e:\MOVIEPY\FFMPEG-PYTHON.py", line 399, in runffmpeg&#xA;    pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,&#xA;      File "C:\Python39\lib\subprocess.py", line 947, in __init__&#xA;    self._execute_child(args, executable, preexec_fn, close_fds,&#xA;      File "C:\Python39\lib\subprocess.py", line 1416, in _execute_child&#xA;    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,&#xA;    OSError: [WinError 87] The parameter is incorrect&#xA;</module>

  


  final command generated by function will look like :

  


  ffmpeg -i cremovie.mp4 -i a1.wav -filter_complex "[0:v]setpts=PTS*7.489116/4.0 [v]" -map "[v]" -map 1:a -shortest -pix_fmt yuv420p -y output.mp4


  


  i want to extend the video's duration to audio's duration ( video's duration increased to from 4s to 7.48 s)

  


  while running this ffmpeg command in command prompt (CMD) , its working , got no errors but in python , i'm getting errors.
