VLC - трансляция ТВ в сеть -проблема со звуком

[nord_tramper]

Ubuntu 11.04
Локально VLC воспроизводит ТВ с тюнера нормально, но после выхода из VLC остается звук. При трансляции по HTTP, на удаленном компе - есть видео, нет звука. Видео идет как бы рывками. Как это поправить?

З.Ы. в поиске был - не помогло...

[avi9526]

1) Каким образом запускаешь трансляцию?
2) Приведи, плиз, параметры запуска VLC.
3) Если попробовать транслировать просто видео файл, как тогда дела обстоят?

1 и 2
cvlc v4l2:///dev/video0  :input-slave=alsa://pulse :v4l2-tuner-frequency=111250 :v4l2-fps=25 :v4l2-caching=10000 \
--sout "#transcode{vcodec=mp4v,width=320,height=240,vb=3000,acodec=mp3,ab=128,channels=44100,deinterlace,audio-sync}:http{mux=asf,dst=:8080/}" \
--no-sout-rtp-sap --no-sout-standard-sap --no-sout-keep --ttl=10 --sout-all

3. Вроде адекватно, сейчас попробовал. Файл раздавал Theora+Vorbis. ТВ - рываками на всех кодеках.

1) Пока что «PulseAudio» само решает откуда звук взять. Не уверен, поможет ли, но стоит попробовать поиграться со звуковыми входами.

(Нажмите, чтобы показать/скрыть)

1.1) Явно указать в параметрах запуска «VLC» вход аудио. Сперва следует узнать список доступных устройств «PulseAudio», можно так

Код: [Выделить]

pacmd list-sources | grep "name:"Выдаст что-то типа

Код: [Выделить]

name: <alsa_output.pci-0000_01_00.1.hdmi-stereo.monitor>
name: <alsa_output.usb-FORTEMEDIA_FM1083-00-FM1083.analog-mono.monitor>
name: <alsa_input.usb-FORTEMEDIA_FM1083-00-FM1083.analog-mono>
name: <alsa_output.pci-0000_00_14.2.analog-stereo.monitor>
name: <alsa_input.pci-0000_00_14.2.analog-stereo>Выбираешь нужное (если такое есть) и дальше вместо «alsa://pulse» пишешь, например, «pulse://alsa_input.usb-FORTEMEDIA_FM1083-00-FM1083.analog-mono».
Всё, что имеет суффикс «.monitor» — это запись с выхода, т.е. то что ОС выводит на аудио выход можно считать как входной сигнал — тебе не надо.
1.2) А можно поставить программу «PulseAudio Volume Control»

Код: [Выделить]

sudo apt-get install pavucontrolи там в GUI посмотреть/поменять откуда звук считывается (сначала запустить «VLC», конечно).

2) Добавить параметр запуска «--verbose=2» — все что выведет в консоли — сюда в комментарий под спойрером.

3) Добавить параметр запуска «--live-caching=1000». У тебя включено какое-то кеширование, попробуй еще и так.

4) Такой кодек пробовал?

Код: [Выделить]

transcode{vcodec=h264,vb=8000,scale=0.5,acodec=mpga,ab=128,channels=2,samplerate=44100}

I think you need more input caching here…

Usually just too slow cpu/pc compared to encoding settings

Короче говоря:
1) Увеличить входной кэш VLC-сервера, где-то в 2…10 раза — попытка не пытка.
2) Проверить достаточно ли производительности. Посмотри на загрузку ЦП, причем не сумарную циферку, а для каждого ЦП (ядра). У некоторых кодеров проблема с многопоточностью. Если увидишь что один ЦП загружен на 100%, а остальные простаивают — скорее всего это и есть узкое место.
3) Напиши конфигурацию железа.
4) Попробуй для начала без звука (убери «:input-slave=*»)
5) VLC староват, пора бы попробовать новую версию — собрать из исходников, не знаю возможно ли.

[nord_tramper]

Итог:
pulseaudio ~ 70%
vlc ~ 23%
общая загрузка пройа под 100%

Выключаем захват звука и получаем видео без тормозов и загрузку процессора порядка 20%

Как лечить звук?

[avi9526]

1. Напиши ещё раз всю команду запуска VLC, что бы знать, что там было дописано.
2. Попробуй передавать только звук. «PulseAudio» загружает ЦП?
3. Если VLC воспроизводит, а не транслирует ТВ поток, «PulseAudio» загружает ЦП?
4. Ты пробовал явно указывать откуда звук брать заместо «alsa://pulse»? Приведи вывод команды

Код: [Выделить]

pacmd list-sources | grep "name:"5. Попробуй другие кодеки для аудио
6. Возможно стоит обойти «PulseAudio» и принимать звук из «ALSA». Приведи вывод команды

Код: [Выделить]

aplay -l

(Нажмите, чтобы показать/скрыть)

Она выводит что-то типа

card X: SB [HDA ATI SB], device Y: ALC889 Analog [ALC889 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

только вместо X и Y цифры, выбираешь нужное, скармливаешь «VLC»

Код: [Выделить]

alsa://hw:X,Y(опять же, вместо X и Y цифры которые были выше)
Или можно сложнее на основе вывода команды
