![]() Here, the Huffyuv codec is used, which is fast, but produces huge file sizes. $ ffmpeg -f x11grab -video_size 1920x1080 -framerate 25 -i $DISPLAY -c:v ffvhuff screen.mkv To take a screencast screen.mkv with lossless encoding and without audio: Where -video_size specifies the size of the area to capture. $ ffmpeg -f x11grab -video_size 1920x1080 -i $DISPLAY -vframes 1 screen.png See FFmpeg encoding wiki and ffmpeg(1) § EXAMPLES.įFmpeg includes the x11grab and ALSA virtual devices that enable capturing the entire user display and audio input. However you may want to force the number of threads available by the parameter -threads number. FFmpeg should automatically choose the number of CPU threads available.Failing to do so may cause parameters being skipped or will prevent FFmpeg from executing. It is important that parameters are specified in the correct order (e.g.So in a nutshell: DVD>M4V (or MP4 probably) using Handbrake>WAV Using the Command Prompt. I went ahead and tested another live music DVD as well and I got that same noise. The insanely loud static sound I would hear on each drum beat when attempting to use Audacity to convert from VOB to WAV was not present and the audio was perfect. Credit for finding the command from this site: Open the Command Prompt, then type in ffmpeg - “sourcefile.m4v” “destinationfile.wav” and press Enter.I used this video, there’s a download to MMFPeg in the description. Note that my version of Handbrake, I specifically customized based on this video: But I will be using Audacity to split the file later on. ![]() I only decided to come post here after finding a video on YouTube on how to do this with Audacity but was having problems. I assumed that I needed to use it to do this, apparently not. It may not be the most direct way of going about it but it works. I wanted to come back and inform you all that I actually figured out how to do this. Regarding a installing the full FFMPeg package, I tried that yesterday and I think that’s eventually how I got ahold of the file avformat-55.dll. I did attempt to play the VOB files from both the CD (then I realized that wouldn’t have worked, oops), and then by copying it to the hard drive. It worked just fine for one of my files, but for others, it had a file size limitation. I did see at least one VOB to WAV online file converter. I can handle splitting and combining WAV tracks with Audacity pretty easily. Is there a way to extract WAV audio from a M4V filetype? That would solve my problem. That said, I’m looking to make audio tracks out of the DVD, if that’s even possible. I’m not too familiar with the legalities of all of this, but I’m not looking to make a profit, I just want to get away from physically having to dig out a disc to play something. I was able to rip the DVD with handbrake (I could either choose M4V or MP4, I went with M4V), and while playing the video, the audio sounds just fine. At the same time, the DISCOGS page states that it’s a US release, which would make sense, since I’m in the USA. On the disc itself on the underside, there’s a number printed, and there’s also a website to an Australian website. Regarding region, well, I don’t quite understand this one. ![]() ![]() In fact, here is the DISCOGS site for reference: The first two CDs are audio and the 3rd disc is a DVD, that’s the one in question. The DVD of which I’m trying to RIP is part of a set called AC/DC Backtracks. For all you know, his track was a clear male voice saying, “This movie is protected by the fairplay music system.” I would feel a lot more fuzzy-warm about this had the demo actually played the music. We turned it in to the library administrators. We searched enough branches and eventually found a different issue of the same movie which would play. The Los Angeles Library System got stuck with a DVD movie a while back that was so well protected, a bunch of us couldn’t play it at all. DVD players “know” to correct the trash by searching for “hidden” tracks which is where the movie is. One favorite trick is to produce normal-looking DVD tracks and pathways that are trash. Audacity may need you to install the FFMpeg software to open AC3.ĭo you know which of the copy protection schemes yours has? It can have more than one. When we were making these, we would sometimes run out of room (we could only burn single layer) so we would skip the large PCM sound and only use the smaller AC3 track. ![]() If commercial DVD, was yours region friendly? ![]()
