Oi Estou tentando transmitir um arquivo de vídeo (localizado no disco rígido da máquina local) para a rede doméstica / LAN.
Estou tentando fazer isso a partir de uma semana. Eu tentei todo o recurso que encontrei então como último recurso, fazendo esta pergunta aqui.
1. O arquivo de vídeo está presente no disco rígido da máquina local.
2. precisa transmitir através do protocolo HTTP.
3. Qualquer servidor GPL funcionaria, no entanto preferiria ffmpeg ou vlc.
Obrigado. Eu aprecio qualquer ajuda sobre isso.
Aqui estão algumas coisas que eu já tentei.
VLC:
Isso funciona intermitentemente. Mas nenhum áudio está chegando, apenas o vídeo é recebido.
No final do servidor:
ffmpeg -i sample.mp4 -vcodec libx264 -acodec aac -ar 48000 -strict experimental -f flv "rtmp://127.0.0.1:1935/live/myStream"
vlc rtp://@10.1.10.102:9001
ffmpeg:
etapa 1:
executando o servidor ffmpeg
ffserver -d -f /etc/ffserver.conf
ffserver version N-80026-g936751b Copyright (c) 2000-2016 the FFmpeg developers
etapa 2: fluxo
ffmpeg -i SampleVideo_1280x720_2mb.mp4 -vcodec libx264 -acodec aac -ar 48000 -strict experimental -f flv "rtmp://localhost/live/myStream"

Nota:
O comando a seguir não apresenta nenhum erro. mas o cliente não está mostrando nenhum vídeo ou áudio,
ffmpeg -re -i "SampleVideo_1280x720_2mb.mp4" -f mpegts "udp://10.1.10.102:2000"
Este diz tubo quebrado:
