ffmpeg stuck at startup; Input/Output error #1052

Hello,
I have stream server using nginx 1.12.0, nginx-rtmp-module 1.1.11 and ffmpeg 3.2.5-1

bpo8+1. When I connect to nginx using OBS everything goes fine, but ffmpeg often stuck at startup, but hardly ever doesn’t goes stuck and everything works fine.

My command for ffmpeg:

FFmpeg output before it goes stuck

Nginx receive play command, because I can find it in access log.

Situation is same with this very simple command that should ends with error there is needed atleast one output.

When I kill ffmepg with CTRL+C I get Input/Output error.

There shouldn’t be any problem with RTMP stream, because it plays normally in VLC.

In my PC everything worked fine, but in server of my company I get this error.

The text was updated successfully, but these errors were encountered:

Solved. Problem was with nginx 1.12.0, 1.10.3 is ok.

@PapiCZ
If you still monitor this thread, I have the same issues you had, but unfortunately going to nginx 1.10.3 did not fix it.
Would you care to give your ffmpeg build version ? I am wondering if this has to do with ffmpeg or nginx or rtmp module.
an exec to ffmpeg is simply unusable as a result, extremely frustrating .

Here is output of ffmpeg -version

I use it with nginx rtmp module 1.1.11.

Thanks a lot. Figured out the reason of the errors: multi workers was on auto instead of 1.

@pkviet Thanks! I had the same problem. ffmpeg would sometimes start and process the stream correctly but often it would just fail. Setting worker_processes to 1 fixed it.

This issue disappeared when I compiled the module statically in nginx.

I am getting input/output error when I am using FFmpeg. Ngnix is working fine status come ok for NGINX and snapped code is below please help me out

Openwrt Input/output error #739

I have successfully cross-compiled nginx-1.9.6 with PCRE-libs and nginx-rtmp-module.
and ffmpeg-2.6.2 with rtmp muxer/demuxer option.

Under Openwrt ffmpeg can successfully feed remote i386 nginx server with nginx-rtmp-module:

Решено. Проблема была с nginx 1.12.0, 1.10.3 в порядке.

@PapiCZ
Если вы по-прежнему отслеживаете этот поток, у меня те же проблемы, что и у вас, но, к сожалению, переход на nginx 1.10.3 не помог их.
Не хотели бы вы дать свою версию сборки ffmpeg? Мне интересно, связано ли это с модулем ffmpeg, nginx или rtmp.
exec для ffmpeg в результате просто непригоден для использования, что очень расстраивает …

Вот вывод ffmpeg -version

Я использую его с модулем nginx rtmp 1.1.11.

Большое спасибо. Выяснили причину ошибок: multi worker был на auto вместо 1.

@pkviet Спасибо! У меня такая же проблема. ffmpeg иногда запускал и обрабатывал поток правильно, но часто просто выходил из строя. Установка worker_processes в 1 исправила это.

Эта проблема исчезла, когда я статически скомпилировал модуль в nginx.

Я получаю ошибку ввода / вывода, когда использую FFmpeg. Ngnix работает нормально, статус подходит для NGINX, и код привязки ниже, пожалуйста, помогите мне

Some context: I have an Nginx server (with rtmp-module) on a Ubuntu-16.04 VM. I’m using it to receive an input rtmp stream from my PC. FFmpeg is then used in the VM to take this input and relay to multiple destinations after transcoding, overlaying a lower third, and changing the volume.

FFmpeg version: ffmpeg version N-92147-gf85fa10 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10) 20160609 configuration: —pkg-config-flags=—static —extra-cflags=-I/home/btech11/ffmpeg_build/include —extra-ldflags=-L/home/btech11/ffmpeg_build/lib —extra-libs=’-lpthread -lm’ —enable-gpl —enable-libass —enable-libfdk-aac —enable-libfreetype —enable-libmp3lame —enable-libopus —enable-libvorbis —enable-libvpx —enable-libx264 —enable-libx265 —enable-libzmq —enable-librtmp —enable-network —enable-nonfree libavutil 56. 19.101 / 56. 19.101 libavcodec 58. 32.100 / 58. 32.100 libavformat 58. 18.104 / 58. 18.104 libavdevice 58. 4.105 / 58. 4.105 libavfilter 7. 33.100 / 7. 33.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 libpostproc 55. 2.100 / 55. 2.100

I’ve also tried it with a codec copy command to try and eliminate the problem: /usr/local/bin/ffmpeg -nostdin -thread_queue_size 512 -i rtmp://127.0.0.1:1935/stream1/input -c copy -f flv rtmp://a.rtmp.youtube.com/live2/[my key] -y

The stream seems to work for longer but errors out after an hour with below error. The second time I ran this command however, the stream worked for 2 hrs 40 minutes, before I had to quit to get some other work done.

Strangely enough, doing a vcodec copy did not throw any error even after 2 hours, 20 minutes of streaming. I’m doing a longer duration stream to further validate this. Will update this post with any info. The command I used was: /usr/local/bin/ffmpeg -nostdin -thread_queue_size 512 -i rtmp://127.0.0.1:1935/stream1/input -af azmq,volume=2 -c:a libfdk_aac -vcodec copy -f flv rtmp://a.rtmp.youtube.com/live2/[my key] -y UPDATE ON THE ABOVE VCODEC COPY: Just did another test and it errored out after 19 mins. So no go. :(

Possibilities I’ve eliminated: My bandwidth from the PC to the VM is between 40-80mbps upload and download. I’m able to stream fine from my PC using OBS to youtube for 7-8 hrs. Also when I either stop OBS on my PC or disconnect the internet on my PC, ffmpeg behaves very differently from the above errors. It freezes for a few seconds, and if the input comes back inthat time, picks up where it left off, So the above error. So I dont believe it’s a network issue from my system.

The error occurs with various destinations: youtube, facebook, even another endpoint on the same nginx server, so it’s not an issue with network from VM to youtube etc.

Another interesting thing I found, if I run two ffmpeg instances from the same input to two different youtube livestreams, they seem to error out independently. So doesnt seem to be an input issue at all.

Error DOES NOT occur while streaming out of a local mp4 file using codec copy, so it seems to be an error with an input rtmp stream. Or at least no error for a couple of hours of streaming. Not sure if that was just my good luck.

RTMP with FFMPEG + NGINX Doesn’t play in VLC

I’ve got a RTMP stream setup with FFMPEG -> NGINX which I can play just fine with FFPLAY. However, it does not work with VLC.

Yes, I can see that. But it works fine with ffplay.

So I’m wondering what the difference is?

Аудио и видео, серия 3: использование nginx для создания локальной потоковой службы

  • Предисловие
  • Фактическая операция
    • Установка модуля nginx + nginx-rtmp
    • Настроить приложение nginx rtmp
    • Начать потоковую передачу ffmpeg push
    • Испытание на растяжение

Предисловие

Аудио и видео серии:
Аудио и видео серия 1: потоковая передача ffmpeg + rtmp
Аудио и видео серия 2: ffmpeg декодирует H.264 в RGB

Друзья, которым интересно, могут посмотреть.

В предыдущем разделе мы использовали ffmpeg, чтобы вытащить видео Mango Channel и преобразовать его в rgb. Однако Mango Channel не работал должным образом, и карта была извлечена, поэтому я не знаю, проблема ли это в моем коде или сервере Mango Channel. Чтобы устранить это Когда возникает проблема, мы создадим локальный сервер nginx в этом разделе, будем использовать ffmpeg для локального push, а затем использовать наш собственный код и проигрыватель VLC для тестирования PK.

Почему вы хотите это сделать, потому что локальная потоковая передача и локальный прием могут гарантировать, что запущенный поток определенно будет плавным, так что если есть проблема с вашим кодом (например, он застрял), вы можете узнать об этом впервые, что эквивалентно устранению проблемы с сервером .

Фактическая операция

Установка модуля nginx + nginx-rtmp

Адрес загрузки nginx: http://nginx.org/en/download.html

Я сам скачал версию Mainline. Скачав и распаковав ее, я найдунастроить исполняемый файл, Подождите, мы будем использовать его для создания файлов Makefile.

Тогда вот описание параметра для компиляции nginx: http://nginx.org/en/docs/configure.html

Загрузка модуля nginx-rtmp: используйте команду git clone напрямую
git clone https://github.com/arut/nginx-rtmp-module.git

Поскольку нам нужно только реализовать потоковую передачу и никаких других модулей и сред не требуется, при компиляции нам нужно только установить nginx-rtmp-module и сертификат openssl.

Сначала посмотрим на openssl, где он находится.

Просмотрите команду openssl location:

which openssl

дисплей:/usr/local/openssl/bin/openssl

Удалите bin / openssl, в каталоге nginx используйте команду configure:

./configure --with-openssl=/usr/local/openssl/ --add-module=nginx-rtmp-module

нота,--with-openssl=Заполните только что полученный путь openssl и удалите егоbin/openssl。
--add-module=заполнитьnginx-rtmp-moduleмаршрут.

Проблемы, обнаруженные при эксплуатации:

'/usr/local/openssl/.openssl/include/openssl/ssl.h' failed

Говорят, что каталог .openssl / не найден. Измените файл auto / lib / openssl / conf в каталоге nginx на правильный путь.

  CORE_INCS="$CORE_INCS $OPENSSL/include"
  CORE_DEPS="$CORE_DEPS $OPENSSL/include/openssl/ssl.h"
  CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libssl.a"
  CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libcrypto.a"

Запускаем еще раз:

./configure --with-openssl=/usr/local/openssl/ --add-module=nginx-rtmp-module
make -j2
sudo make install

Установка завершена.

Настроить приложение nginx rtmp

sudo vim /usr/local/nginx/conf/nginx.conf

Измените nginx.conf и добавьте приложение rtmp

rtmp {
	server {
		listen 1935;
		chunk_size 4096;
		application rtmplive {
			live on;
			max_connections 1024;
			allow publish all; # control access privilege
			allow play all; # control access privilege
			}
		}
}

среди них:
Имя приложения — rtmplive;
Максимальное количество подключений — 1024;
размер отдельных данных chunk_size — 4096;
Порт прослушивания — 1935.

Откройте службу nginx (обратите внимание, что вам нужно использовать sudu, иначе разрешений будет недостаточно)

sudo /usr/local/nginx/sbin/nginx

Ошибка,bind() to 0.0.0.0:80 failed (98: Address already in use)

Причина в том, что nginx был включен, используйтеps -e | grep nginxПроверьте, запущена ли служба nginx, если да, вы можете сначалаsudo kill -9 номер PID

Затем запустите nginx:

sudo /usr/local/nginx/sbin/nginx

Или вы можете перезагрузить программу nginx:

 /usr/local/nginx/sbin/nginx -s reload

Здесь настроен nginx.

Начать потоковую передачу ffmpeg push

ffmpeg -re -i sss.mp4 -c copy -f flv  rtmp://localhost:1935/live/rtmplive

Произошла ошибка:

rtmp://localhost:1935/live/mytv: Input/output error

На самом деле адрес неверный.
Приходите снова:

ffmpeg -re -i sss.mp4 -c copy -f flv  rtmp://localhost:1935/rtmplive

Локальный толчок завершен.

Испытание на растяжение

Наконец-то пришло время для ПК,VLC плеерс участиемМой код (подробности см. В предыдущем разделе) ПК,Кто одержит победу?

Думаю, мой код победит.

VLC открывает сетевой поток, введитеrtmp://localhost:1935/live/mytv: Input/output error
Мой код также изменил адрес rtmp и включил его.

После получасового тестирования VLC сильно отставал, поэтому я перезапустил потоковую передачу VLC и обнаружил, что она все еще работает медленно.

Два часа спустя код все еще работает, сбоев нет, а скорость все еще выше, чем у VLC, я думаю, это примерно на несколько секунд быстрее.

Результаты теста следующие: левая сторона — мой код, а правая — проигрыватель VLC. Используя дисплей OPENCV, вы можете видеть, что следующая строка была написана слева, а правая часть еще не написана, очевидно, медленнее, чем левая.

Итак, окончательная победа принадлежит мне, хе-хе.

Что ж, этот раздел подошел к концу. Выполните эти основные задачи. Затем я могу изменить код в предыдущем разделе, чтобы он соответствовал последнему API без предупреждения, или представить систему ROS.
