where is the recorded file?

[ayanoco]

1.Where was the file saved ? There are no mov. in the "bin" folder. 2.I would like to save the movie drawn by my project in the file. Is it possible with your ofxVideoRecorder? Where should I rewrite? Now the FaceTime HD camera has been attached. Sorry for elementary question. Any help would be appreciated. Thank you.

[timscaffidi]

The video should be in bin/data/. I'm not sure i understand your second question, but if you want to save to a specific location it would be possible by using the setupCustomOutput function and providing the command line options directly to ffmpeg, one of them being the output file location. I hope this helps.

Now I could make .mov file in bin/data. Thank you! But I can't open the mov. file.. even in VLC media player. In this case, do you think the way I install the ffmepg was wrong? Sorry for poor English..

[timscaffidi]

If you are unable to open the file, it could be a few things. Are you certain you have ffmpeg installed correctly? do you see any errors from it in the console? It could be that the default combination of audio and video codecs are not supported by your version of ffmpeg. You can try changing them. run ffmpeg -codecs to see what codecs are available, if they have an E in the first column, then they support encoding.

You can also try a different container than .mov, you could use .mp4 if you want, or .avi

It may also be that quicktime cant open the file but maybe VLC can.

I hope this helps

Thank you for replying Now I'm trying with "mpeg4" and "mp3" combination and set fileExt=".mov", for example. When I run "ffmpeg-codecs", I see the lines like DEV.L. mpeg4 MPEG-4 part 2 (encoders: mpeg4 libxvid ) DEA.L. mp3 MP3 (MPEG audio layer 3) (decoders: mp3 mp3float ) (encoders: libmp3lame ) and when I run "ffmpeg-formats", I see the lines like E mov QuickTime / MOV E mp4 MP4 (MPEG-4 Part 14) They all have "E" so I thought it's no problem here..am I right ? I wonder why.. :(

[timscaffidi]

right, that looks like it should work.

How about errors on the command line? is the program properly closing the video file? are any frames being added to it? Post your console output from a short run, and I might be able to get a better insight

[ayanoco]

That was the problem.. I've only seen the last line saying "being terminated!" and thought "ok!" Excuse me. Now I'm trying NOT to attach video device and capture the Fbo seeing this page ( It's Japanese though http://blog.rettuce.com/openframeworks/fbo_capture/

I see that it is skipping tons of frames. Are you actually recording audio as well? In order to keep things in sync, it will skip/repeat video frames as needed depending on the amount of time accumulated in the audio stream. So if you have it set up to record audio, but you dont send it any audio frames, then you also wont get any video.

You can make not record audio at all and then it will always record the video frame you give it.

[ayanoco]

That's really helpful :) Actually I've muted"//" the audio line of somewhere. I'll check and try it and tell you the result before long. I'm sorry I have to go today.. Thank you :)

[ayanoco]

Hello, (( I'm sorry it was long )) As you mentioned, it was the problem of the sounds. I had not been able to understand what you wrote in README but now I can :) , and also I’m able to record and open the file. Thanks! But there’s still the problem of the quality of the image.The color of the recorded file is more dark than the original color. Short-run says like this: … [warning] ofThread: - name: Thread 3 - Calling startThread with verbose is deprecated. [warning] ofThread: - name: Thread 1 - Calling startThread with verbose is deprecated. … Should I do something with ofThread to improve the image quality? Or should I check another point? Any help would be appreciated. Thank you.

[timscaffidi]

Those warnings have nothing to do with the video quality.

Try using a different video codec and/or bitrate to see if it changes the output color.

[ayanoco]

I could do it with "prores", but with "h264", I can't open the recorded file. Short run says "No pixel format specified, yuv444p for H.264 encoding chosen."...Is this the reason why I can't open the file? What's the matter with h264...?

[timscaffidi]

h264 support is highly dependent on your build of ffmpeg, some have support, others dont

[ayanoco]

I see.. I can see "E" in the h264 line but you mean there's many kind of h264 ? Maybe there're more issues that I should study. Anyway, thank you again, it was really helpful :)

[timscaffidi]

If your ffmpeg supports it, then you may just need to find a container to use with it that will work on your platform. On Mac, quicktime usually likes h264 with a .mp4 container. If you are using VLC to play files then it will support h264 within more containers.

[timscaffidi]

Also, h264 may need additional parameters aside from just the bitrate in order to get a working video. For now, you can specify those options using a custom output string with ofxVideoRecorder::setupCustomOutput()
