Second Birthday Wording

Cinelerra and a few bugs.




Oh yes, forced to stay home to finish a job! But there was talk of Cinelerra, for this wonderful tool that some time has become part of my favorite shows has a bug and nice, big, do not let you do if you use the Render "yuv4mpeg Stream" along with "ffmpeg". This combination is used to make plans for low quality video (in this case I was using videos downloaded from YouTube). Error you get: "Data processing failure, int YUVStream: write_frame (uint8_t **): write_frame () failed: system error =
(failed read / write)"

There is also another bug.


first solution Bug

(Window on the render)

problem.
The problem lies in a line of "Use Pipe" and unfortunately, if not delete that part of the Render will not start. Suppose the line sia " ffmpeg -f yuv4mpegpipe -i - -y -target dvd -ilme -ildct -hq -f mpeg2video %" per risolvere la questione dobbiamo eliminare la stringa "ilme -ildct -hq" e così facendo la nostra vecchia riga diventa " ffmpeg -f yuv4mpegpipe -i - -y -target dvd -f mpeg2video %"

Ecco fatto, ora il render dovrebbe partire.

Altro piccolo bug, non relativo a Cinelerra.

Devo dire che Pulseaudio mi è sempre piaciuto, però è sempre stato integrato malamente in Ubuntu, IMHO, Facciamo un esempio? Karmic. Infatti nell'ultima release da ciò che ho capito non è stato introdotto un pacchetto e quindi potremmo avere grossi problemi durante la riproduzione nel compositor di Cinelerra.

Soluzione 1) Remove Pulseaudio. (Not recommended)

Just open a terminal and type "sudo apt-get remove pulseaudio". ---> Consequences? Will not want to hear two sounds at once, such as Skype and a video to VLC. I forgot, the applet disappears even for the volume, turns typing in terminal "alsamixer" and adjust the controls.

Solution 2) Install a package.

Open the terminal: " sudo apt-get install libsdl1.2debian-pulseaudio"

I hope to be helpful and if you are interested in Cinelerra and the world will turn around just read this wonderful guide .
