FFMPEG: Как выбрать поток из всех потока

Question

Я пытаюсь преобразовать UDP поток (который genrated от сигнала DVB) в HLS m3u8 файл с этим кодом:

ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8 

UDP поток содержит 1 канала (в данном случае IRIB-TV1).

Когда я запускаю этот код FFmpeg обнаружить все службы и канала, который струился из DVB карты с этим сообщением:

Input #0, mpegts, from 'udp://239.1.2.1:60001': 
Duration: N/A, start: 77906.812644, bitrate: N/A 
Program 101

Stream #0:1[0x3f3](per): Audio: aac_latm ([17][0][0][0]/0x0011), 48000 Hz, stereo, fltp 
Program 102 
Metadata:

    service_provider: IRIB 
Program 104 
Metadata: 
    service_name : IRIB-TV4 
    service_provider: IRIB 

Как вы видите FFmpeg finf 4 канала в потоке UDP, но VLC играть только канал 1 (IRIB-TV1).

Теперь у меня есть есть 2 вопроса:

1-Могу ли я получить все каналы и услуги через этот FFmpeg код?

2-Могу ли я выбрать Spesial поток из этого FFmpeg кода? (Я знаю, что FFmpeg может выбрать поток с -map otion, но я хочу, чтобы выбрать другой service_name, что в выходной журнал)
