What's a good free desktop screen recorder?

Well, I don't want to download the whole video. Just parts of the very long and huge live streams. Hi Ant, I usually see you over in the iOS groups. Good to see you on the Windows freeware section of Usenet! Lots of ways to accomplish what you want, but, if you do use the youtube-dl.exe that Mayayana seems to be hinting at, you'll need to know _how_ to install it (which isn't intuitive). To save you the effort (which is what Usenet is all about), and since I'm not about imaginary solutions like so many others are, here are my hard-won reproducible real-world notes on exactly how to install the command line youtube download utility successfully. 01. Install Microsoft Visual C++ 2010 Redistributable Package (x86) https://www.microsoft.com/en-US/down...s.aspx?id=5555 02. Upate Microsoft Visual C++ 2010 Service Pack 1 Redistributable Package MFC Security Update https://www.microsoft.com/en-us/down....aspx?id=26999 03: Get ffmpeg http://ffmpeg.zeranoe.com/builds/ http://ffmpeg.zeranoe.com/builds/win...n64-static.zip Put the three executables in the same directory as the youtube-dl.exe ffmpeg.exe ffplay.exe ffprobe.exe The -x is what needs ffmpeg although you can set it to -x, --extract-audio = Convert video files to audio-only files (requires ffmpeg or avconv and ffprobe or avprobe) You can also just point to the FFMPEG directory: --ffmpeg-location PATH = Location of the ffmpeg/avconv binary; 04. Then get the right youtube-dl.exe that uses Visusal C & not python! https://youtube-dl.org/ http://rg3.github.io/youtube-dl/download.html https://yt-dl.org/downloads/2018.08.28/youtube-dl.exe 05. Check the hash! --------------------------- Checksum information --------------------------- Name: youtube-dl.exe Size: 7955964 bytes (7 MB) SHA256: 935D5FD32932BF0A6D842F28E168D84F7FC674CD995A5A4646 D9A70145B6B255 --------------------------- OK --------------------------- 06. Then download a video as an OPUS file: youtube-dl.exe http://whatevervideourl.com 07. Download a video as an MP4 file: youtube-dl.exe -f 18 http://whatevervideourl.com 08. Download and extract just the audio as an M4A: youtube-dl.exe -f 140 http://whatevervideourl.com 09. Download and extract just the audio as an MP3: youtube-dl.exe -x --audio-format mp3 --audio-quality 0 http://whatevervideourl.com 10. Download the videos in a playlist text file: youtube-dl.exe -ciwo "%(title)s.%(ext)s" -a myPlayList.txt Where the myPlayList.txt simply contains a list of URLs, one per line As Mayayana noted, you have other options, e.g., to download the offline installer for camstudio. To always add value to every thread, here's my list, so far, of the free tools you _can_ use, in order of best to worst but this order is super preliminary until more data is known about the shenanigans they pull. o camstudio o vlc o apowerrec o debut o dvdvideosoft o ezvid o flashback o goplay o obs o gamedvr o sharex o smartpixel o tinytake o icecream o screenomatic |

"Paul" wrote | Read the article first. | | https://en.wikipedia.org/wiki/CamStudio | Second post: I do wonder about the diagonal image. The program is small, simple and easy to use. VLC plays the resulting AVI files fine. But if I use VLC to convert to mp4 or if I load it into Avidemux, in both cases it shows up as a diagonal image. The video seems to work. It just displays skewed at about a 45 degree angle. I've never seen anything like that before. If you don't set the video codec, recording is in BI_RGB, which isn't particularly standardized. FFMPEG has a number of RGB formats, where no compression is done, and pixels are arranged in particular ways/orders. Since FFMPEG likely produced the output, you'd expect (but wouldn't always be right) the FFMPEG tool to consume that material too. You can run your video through FFMPEG and use another CODEC like MJPEG for a quick and dirty conversion. I didn't waste time on this. There's no audio, so why would I care ? CamStudio is a dumpster fire. I tried it on Windows 10 and I can't do a damn thing with audio. Not a thing. I'm getting some video recording, so that's not a problem. Even if I can't get a decent capture rate from "CamStudio_Setup_2-7_r316". (I screwed up the caption a bit - the Microsoft Video 1 CODEC captured the video pane on the bottom of the picture.) https://i.postimg.cc/8zdKK40c/camstu...o-no-audio.jpg The source material is my standard video for test recording, in case you were worried about my "sense of taste" :-/ If you can fix the lip sync on that, you can fix it on anything.

It would probably have been good if you'd said in the first place that you wanted to capture a streaming video. Using a screen capture utility isn't the best place to start if that's what you're after. The stream capture utilities others have mentioned are much better ways of doing that. Probably the command-line ones are best (they're nearly always more versatile), but for a relatively simple GUI, I find DownloadHelper captures a fair number. However, I use it in a pre-revolution version of Firefox - I think it's still available with the current version, but I don't know how well it works. Of course, as you might expect, although it _is_ available for Chrome, it doesn't work for YouTube, since Chrome and YouTube are both Google products and (if I read it right) they made it a condition of listing it in the Chrome add-on store that it didn't.

Also, it has to work well on a decade old updated 64-bit W7 HPE SP1 PC with 6 GB of RAM and ATI Radeon 4870 video card (512 MB of RAM). At this point, Youtube-DL is looking better and better. Even if it means downloading the whole thing. 1) Doesn't use a lot of CPU during download. 2) Downloads faster than RT. A 12 hour conference might download in 4 hours. The video is broken into pieces and downloaded in parallel. 3) Doesn't ruin lipsync like screen capture does. Youtube-DL works with a ton of websites. Even my local news channel is in the list of tested sources for capture. The tool does a lot more than just Youtube. While there is a feature request filed with Youtube-DL to support "interval capture", it's too hard to work out the details, which is why the developer hasn't implemented it. The developer works with "byte offsets", and there is no guaranteed mapping between a particular point in time, and how many bytes have already been played at that point. Lots of video is VBR and unpredictable that way. ******* You can always boot Linux and do it there. Windows has GDIgrab, Linux has X11grab, so both platforms support ideas like this.

It seems to have a means to timestamp the video and audio stream, and it did a better job of maintaining lipsync. On the minus side, there were a couple non-monotonic audio timestamps, which causes the capture to hiccup a bit. But on the plus side, it otherwise seemed to keep things aligned. You might look at your audio chip, and if the "native" clock rate is 48KHz, select 48KHz for capture/playback choices, so no re-clocking is going on at the hardware level. I didn't thoroughly test means to correct the hiccup, but perhaps with a bit of work you can bring it under control. It's also possible it had something to do with Pulseaudio, so who knows... Paul |

I looked that up and found they came from a company that gives away various things. The have a screen capture program using their own DLLs. It's only about 2 MB.

No, this won't work since I need it in 64-bit Windows 7. That's true, but if you do decide to test it, you can use that as a "standard" to compare to the Windows-side offerings. I can't even do that good using FFMPEG here. Any tool derived from FFMPEG, is likely to "wander" just as much as FFMPEG does. For example, I can do this in Windows, but the lipsync isn't as good as SimpleScreenRecorder. I think this was the syntax for Windows 10. Some Windows OSes, the name of the audio is truncated to fewer characters. C:\FFMPEG\bin\ffmpeg -framerate 30 -f gdigrab -i desktop -f dshow -sample_rate 44100 -i audio="Stereo Mix (Realtek High Definition Audio)" -vcodec mjpeg -acodec pcm_s16le F:\out.mov FFMPEG allows querying sources. Using the names the first command returns, you can adjust the second and third commands to get details for the source in question. The details are then used when selecting parameters for commands like the previous line. ffmpeg -list_devices true -f dshow -i dummy ffmpeg -f dshow -list_options true -i video="some video source" ffmpeg -f dshow -list_options true -i audio="some audio source" And that FFMPEG command in Linux, would likely do just as bad a job at lipsync. In Linux, you'd replace gdigrab with x11grab, and you'd need to adjust the name of the audio and so on. FFMPEG has "equivalent" capabilities in Linux. But any sync issues it might have, are buried in the engine details. I can't tell you what SimpleScreenRecorder is doing, but whatever it is, they're pretty proud of it, because they put up an actual "sync graphic" on the screen while the capture is running. Paul |

But in contrast, those appear to be _alternatives_, so I wouldn't have continued the number sequence. You are 100% correct. Those are actually a cut and paste from my log file. (I keep a log file on all installations.) So _next_ time I post those instructions, I'll break up the number scheme. To remember, I already made the changes in my log file. Also: When you say "download ... command http://whatevervideourl.com", does whatevervideourl.com have to be the URL of the actual video itself, or can it be the URL of the containing webpage (such as a YouTube page)? Hi J. P. Gilliver, I'm not the best person to ask that question but I'll answer from what I know which is only from experience. Both methods work depending on what you're downloading. For example, if you're downloading a Youtube video, you can use the page that got you to that youtube video, or you can use the video itself. Remember this youtube-dl works on, oh, I don't know, a hundred different web sites or so, so it's not just for youtube. For those web sites, like news sites or whatever, most of the time the main URL that got you to the web page works the same as the url to the actual video inside the web page, but not always. I'm sure you're mileage will vary depending on the web page. If you have a specific video you're interested in, I can test it for you. Also others will know a LOT more than I do as I only use it to download documentaries for the most part, and now Android tutorials. SO I'm not a heavy user. The manpage is extensive though... If it has to be the actual video component, does anything you've done in steps 01 to 05 help you actually find what URL to use? Again, it's pretty flexible. If the URL ends up playing a video, even if there is other crap on the page, generally _that_ url works (but not always). I can't really describe it better as I only rarely download a video that isn't on Youtube where, on Youtube, both the main (long) URL works as does the short one. For example, this week I was writing Android apps from Windows using freeware, where I'm a complete noob (these are my first five apps ever) Your first Android app takes about a hour from start to finish https://groups.google.com/forum/#!topic/comp.mobile.android/aW64zYeBtF0 As always, so that others could follow in my footsteps, I posted these URLs into that thread, where I used the youtube downloader so that I could start and stop them at will without having to be in a browser online (they were actually loaded to the iPad using Linux dual boot to do so). Android Studio For Beginners Part 1, 2, 3, 4 by Bill Butterfield, Published on Jun 13, 2017 (mp4) https://youtu.be/dFlPARW5IX8 (part 1) https://youtu.be/6ow3L39Wxmg (part 2) https://youtu.be/rdGpT1pIJlw (part 3) https://youtu.be/bu5Y3uZ6LLM (part 4) But, in reality, these are the URLs I originally used: https://www.youtube.com/watch?v=dFlP...ature=youtu.be (part 1) https://www.youtube.com/watch?v=6ow3...ature=youtu.be (part 2) https://www.youtube.com/watch?v=rdGp...ature=youtu.be (part 3) https://www.youtube.com/watch?v=bu5Y...ature=youtu.be (part 4) Both styles of URLs work o The top of the page o The video embedded inside the page If I understand your question correctly (and I might not), then both URLs work fine, one of which is the page and the other the video in the page. Playlists also work, but I don't use them, but you can point to a playlist that you have on Youtube and it will download everything in the playlist. Again, the manpage has more than you could ever ask for, and, again, I just use it for simple stuff where it does more than what I know. |
