comment ffmpeg unable to record video with audio how to solve it?
Why did you make a screenshot instead of simply copying and pasting? It is text. What is this audio device you're trying to capture? Why are you using OSS? Does /dev/audio or similar exist?

comment Using avconv to convert any video file to mobile Browser
You need to show your actual ffmpeg command and the complete console output. Only saying, "it's do not works" provides no helpful info, so no answer can be given.

comment FFMPG vs AVCONV: Has the CRF metric change?
From the repository? I thought you compiled avconv. You forgot to include the complete console output from each command.

comment FFMPG vs AVCONV: Has the CRF metric change?
You should show the actual commands and the complete console output from each. What's the reason for using avconv instead of ffmpeg?

comment How to convert .ts file into main stream file losslessly?
@lacton Try muxing into matroska: ffmpeg -i 10MB.ts -c copy output.mkv. You will get error: Error parsing AAC extradata, unable to determine samplerate. That is why my MKV example re-encoded the audio. Also see #4472: AAC copy from stream without encoding fails and lavf/mkv: Fix AAC remuxing. However, none of this may apply to your large, untruncated input file and it may work as expected.

@SuperSluether Lossless makes huge files. By "lossless" I believe lacton meant "remuxing".

I'm not familiar with VLC for converting, but I added an answer using ffmpeg.

You mentioned you wanted to remux, not re-encode if possible. Are you sure VLC is only remuxing?

comment Batch convert H.265 mkv to H.264 with ffmpeg to make files compatible for re-encoding
Consider stream copying the audio with -c:a copy instead of re-encoding. Also, 0:0 may not always refer to video, and 0:1 may not always refer to audio. You can use a stream specifier to avoid potential issues: -map 0:v -map 0:a if you want all video and audio streams from input 0, or -map 0:v:0 -map 0:a:0 if you only want the first video and audio streams from input 0. If you only want the English audio stream: -map 0:m:language:eng (assuming it is labeled).

comment Hauppauge 610 Analog Video Capture Script or Command
@jbrock I don't think I can provide much without more info about your inputs, such as the console output of: ffmpeg -f v4l2 -i /dev/video0 -f alsa -i default

comment Hauppauge 610 Analog Video Capture Script or Command
Why are you going from MPEG-2 video -> MPEG-2 video -> H.264? If the device already outputs MPEG-2 video then you should simply re-mux it, or if you want H.264 encode directly to that and skip handbrake.

comment Is Ubuntu 15.10 safe for an Ubuntu beginner?
Have you considered trying it as a VM first? That way you can get some experience with installation and usage without needing to worry about messing anything up.

I've encountered this as well on a way-too-small /boot partition. Quite annoying.

@jbrock hqdn3d is a video denoiser; sorry, the answer didn't really specify. I'm not sure why the audio sucks. I'll blame ALSA.

comment Hauppauge 610 Analog Video Capture Script or Command
Try plugging the audio output cable from the camcorder into the Hauppauge device (either the red or white input). Then you have to choose the appropriate device in Device Selection > Audio device name. See FFmpeg Wiki: ALSA for info about that. If you get that working, then we can move onto using ffmpeg to capture, or VLC if you prefer, but ffmpeg will be easier to script (for me at least).

comment Multi-Core Encoding with VP9 FFmpeg
@bodhi.zazen Options before -i will be applied to the input (the decoder or demuxer).
