Eu estou usando o ffmpeg para converter um fluxo RTSP público disponível gratuitamente para um arquivo mp4. Eu posso reproduzir o arquivo muito bem no Chrome usando um cliente de vídeo HTML5 padrão em uma máquina com Windows 7, mas não no IE11. Alguma idéia porque o mp4 não vai jogar no IE11?
ffmpeg -i rtsp://dmzosx001.dpa.act.gov.au/medium -acodec copy
-vcodec copy -f mp4 -movflags frag_keyframe+empty_moov
-reset_timestamps 1 -vsync 1 -flags global_header -bsf:v dump_extra -y output.mp4
Eu forneci o arquivo mp4 online. A URL do arquivo mp4 é http://184.173.147.99:3000/stream Aqui está o cliente HTML5 padrão que abro no IE11
