Não é possível reproduzir o m3u8 ao vivo, mas é capaz de reproduzir o mjpeg usando o ffserver

Question

Oi eu estou tentando configurar o ffserver para transmitir vídeo ao vivo. Para fins de teste, usei aqui o arquivo estático 'temp.mp4'. Quando eu tento transmitir mjpeg, então funciona bem para mim playlist.m3u8 nunca funcionou para mim. Por favor, olhe a configuração e deixe-me saber se alguma alteração é necessária.

1. configuração do servidor

cat /etc/ffserver.conf HTTPPort 8080 HTTPBindAddress 0.0.0.0 MaxHTTPConnections 20 MaxClients 10 MaxBandwidth 5000
#NoDaemon

<Feed webcam.ffm>
      file /tmp/webcam.ffm
      FileMaxSize 200K
      ACL allow 127.0.0.1
      ACL allow localhost
      ACL allow 192.168.1.0 192.168.1.255 </Feed>

<Stream webcam.mjpeg>   Feed webcam.ffm     Format mjpeg    VideoSize 640x360   VideoFrameRate 15   VideoBitRate 2000   VideoQMin 1     VideoQMax 10 </Stream>

<Feed feed1.ffm>    File /tmp/feed1.ffm     FileMaxSize 1G      ACL allow localhost
        ACL allow 127.0.0.1
        ACL allow 192.168.1.0 192.168.1.255 </Feed>

<Stream playlist.m3u8>      Feed feed1.ffm      Format HLS      VideoCodec libx264      VideoFrameRate 30   VideoBitRate 128    VideoSize 704*480   #AVOptionVideo hls_time 10      #AVOptionVideo hls_list_size 0      AVOptionVideo flags +global_header      AudioCodec ac3      AudioBitRate 128    AudioChannels 2     AudioSampleRate 48000  </Stream>

<Stream stat.html>
        Format status
        # Only allow local people to get the status
        ACL allow localhost </Stream>  <Redirect index.html>    # Redirect index.html to the appropriate site    URL http://www.ffmpeg.org/ </Redirect

step2: start ffserver
ffserver -d -loglevel debug -f /etc/ffserver.conf

step3: feed input to ffserver
    ffmpeg -i temp.mp4 -vcodec libx264 -acodec copy -f ssegment -segment_list_flags +live -segment_list playlist.m3u8 -segment_time 10 out%03d.ts  http://127.0.0.1:8080/feed1.ffm

6. Eu tentei jogar localmente, o que funciona sempre para mim. ffplay playlist.m3u8

7. notas extras: abaixo de uma sempre funciona para mim feed: ffmpeg -r 15 -i temp.mp4 link play: ffplay link

Por favor, deixe-me saber como proceder e depurar este ambiente.

Obrigado Vijay
