# E-scripts on creating screencasts (with high-level tools).
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

Oi Reinaldo! Tudo bem? Voce trabalha com video, ne'? Voce pode me dar uma dica? Acho que se voce me der umas palavras-chave eu devo conseguir me virar procurando nas internets...

E' o seguinte... eu so' sei usar Linux, e ate' dois anos atras eu nao entendia absolutamente nada de gravar videos... agora eu entendo pouquissimo, mas ja' gravei uns screencasts sobre coisas de Software Livre, e agora eu gravo algumas das minhas aulas como screencasts tambem...

Eu costumo usar um programa chamado SimpleScreenRecorder, com esses settings aqui... vou mandar uma foto de uma das janelas dele, mas o que importa e' so' a parte dela que diz que o audio vai ser gravado em "Codec: MP3" e "Bit rate (in kbits/s): 128", e incluido num arquivo .mp4 com Codec H.264

Eu achava que isso seria um formato mais ou menos universal que todos os players tocariam numa boa, mas uns alunos meus que tem iPhones me disseram que quando eles tentam assistir esses MP4s eles nao ouvem som

e ai' eu tive que fazer uma coisa bem idiota, que e' subir cada .mp4 pro youtube tambem... exemplo:

http://angg.twu.net/eev-videos/2021-1-C2-somas-1-dicas.mp4

https://www.youtube.com/watch?v=pCD1p9FZYdI

Onde eu posso aprender mais sobre que formatos de video sao "universais" no sentido de que qualquer browser em qualquer celular?

Ooops

De que qualquer browser em qualquer celular deve conseguir tocar eles direito

Desculpa a falta de jeito de ja' ir perguntando coisas tecnicas direto... eu meio que desaprendi como interagir com humanos, e eu ate' ando dizendo - meio a serio e meio de brincadeira - que eu virei a Rainha da Amargura... =S

Fala Zico, tudo certo. O apocalipse afetou todo mundo.

Tenta 96 bits em vez de 128. Alguns telefones não aceitam 128 e os iPhones são merdas caras. O formato de áudio padrão do iPhione é o AAC mas ele costuma suportar o MP3.

Recomendo dois programas que existem para Linux. O Player VLC que vc deve sugerir aos seus alunos por que toca tudo e existe para iphone, andoird etc

E o OBS que ofcialmente é para trasmições mas grava no PC e é um poderoso fácil de usar. Capturara tela é com ele mesmo.

Opa! Obrigado!!!

Ja' me deu um monte de ideias de coisas pra testar e pra pesquisar! Quando ao VLC: eu uso ele e o mplayer pra quase tudo aqui em casa, mas tou tentando fazer com que o material das minhas aulas fique acessivel sem apps extras... ja' tem um monte de alunos que ficam revoltados que 90% das minhas aulas sao discussoes por Telegram com todo mundo mandando foto do que esta' fazendo...

O VLC funciona como conversor. No Windows seria CTRL+R

Tou testando aqui no Linux... o Ctrl-R parece ser pra abrir arquivos, URLs, or discos...

Pra mim e' mais facil usar o ffmpeg pra fazer as conversoes dos audios
