You should probably use flvmeta (http://code.google.com/p/fl... instead of flvtool2.

It's a small tool written in C that is much faster than flvtool2, which is written in ruby, and uses way too much memory.

Есть проблема при конвертации mov (QuickTime) файла в flv. Вот такая команда.
mencoder input.mov -o output.flv -of lavf \
-oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc \
-lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 \
i_certify_that_my_video_stream_does_not_use_b_frames

С -nosound работает. То есть как я понял проблема с
аудио кодеком.
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
AUDIO: 44100 Hz, 2 ch, s16le, 64.0 kbit/4.54% (ratio: 8000->176400)
Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio) decoder)

Но итоге получаю ошибку.
Cannot initialize muxer.
Exiting...

Кто-нибудь сталкивался с подобным?

Hi, I have use the same mencoder command above listed and it works fine. But my video player is a bit big, and when I play the converted flv video, its pixelated,i.e the quality is not good.

What are the things I need to change to make it a size of 407x305 and quality will be better.

Здравствуйте! Спасибо за информацию! Есть вопрос - какая конфигурация сервера подойдёт для создания работоспособного сайта с видеоконтентом (на начальной стадии)?
Спасибо.

Спасибо за пост. mplayer forever.
Но flvtool2 в силу свой чистой скриптовости имхо жутко тормозная штука и на больших роликах массовую конвертацию делает тяжким трудом :) Достойной заменой может послужить Yamdi, делающая то же самое в контексте задачи и работающая в на порядки быстрее.

2alex: Мы писали сами... Наш флеш-девелопер за день наколбасил хотя до этого ваще не видел флеш-фидео. Потому я уверен, что не сильно сложно. Хотя, может, есть и готовое.

Да это я понял. Есть уже существующие и работающие реализации - желательно на флэше? Пробовал http://www.flashcomguru.com... . При перемотке не обрывает старые закачки. 10 раз перемотаю - имею 11 потоков для одного файла. Ещё раз 6-7 перемотаю - плеер повиснет.

2alex: да. именно. он должен читать метаинфо в самом начале и потом при переходах по видео (перематывании) делать ?start=XXX на позицию, указанную в метаинфо рядом с номером ближайшего кейфрейма.

Can i apply this solution for live streaming? (input from a webcam for example)

Can this solution be utilized in a shared hosting environment. For example, could I install and run the mplayer and mencoder on a shared hosting site with GoDaddy. The server is Red Hat Linux with Apache.

Any advice would be greatly appreciated.

Thanks!

When I run the mencoder command, I get this error:

CAN'T GET SPECIFIED FORMAT
Cannot initialize muxer.
Exiting...

Any ideas? Mplayer can play fli files fine...

Thanks for the help.

Small detail in comparison, but what's the best way to get frame grabs of the videos, like YouTube has as a single-image preview?

I completely understand how it works because I've used it on our streaming servers before nginx got same feature.

You probably didn't understand how mod_flv_streaming works: It requires a start-parameter in the url and therefore won't work with (most) flv players out there. See the docs at: http://jan.kneschke.de/proj...

Notice: Read my new article about flash streaming “Flash Video (FLV) Streaming with Nginx” to learn, how to implement streaming server with nginx.

"..Ffmpeg sucks.."

Mplayer/Mencoder relies on ffmpeg to do much of the encoding... - it's included with the package.
