For Windows: Have you tried Input Director? After you install it on the two computers and set it up, you can control both machines and there is an option to Mirror input. There is also the Microsoft Microsoft Garage Mouse without Borders Where you hit Ctrl 3 times to run the commands across all machines. As a note, anything that you create software wise ...

There's a good chance it's a combination of your internet connection and the fact that your not using a graphics card that is causing the playback buffering and stuttering. Something else to keep in mind is that internet connection speeds are typically measured in Mb (Megabits) as opposed to MB (Megabytes) so if your connection speed is actually 50 Mb/s ...

I fixed this issue. Since trying to install the Radeon drivers and having the installation crash I have installed an Nvidia card and after installing those drivers successfully and rebooting the PC everything is working fine now. I am going to keep the ATI card for a later project.

It really depends on your upload speed. bufsize will determine how religious ffmpeg is about keeping your bitrate constant. If you set a bufsize of 64k, as per FFmpeg Wiki: Limiting the output bitrate, it will calculate its current bitrate every 64 kilobytes and adjust accordingly. Smaller sizes for bufsize can be harmful to quality in that they don't allow ...

Not opening is a function of being an executable that hasn't been blessed. In a terminal chmod ugo-x <media_file_name(s)> and then assuming the files are recognized and claimed by an app, they should open.

This post seems to have the answer: "FFMpeg versions after Jan 15 2015 often display this warning. It has been added to warn about possible rate control distortion, otherwise it does not cause any harm." It appears to be triggered when "the presentation time (pts) in the input stream differs from the one in the output stream by more than a fixed limit set ...

You can scale it first and then crop it for better output ;) ffmpeg -ss 10 -i "Ali_Video.mp4" -vframes 1 -filter "scale=-1:300,crop=400:300" "output.jpg" ffmpeg -ss 10 -i "Ali_Video.mp4" -vframes 1 -filter "scale=-1:150,crop=200:150" "output.jpg"

Currently I use another alternative, because I find its specific limitations less annoying: NoScript, set to "Allow scripts globally" and Embeddings -> "Apply these restrictions to whitelisted sites too". Otherwise you may also need to disable the XSS protection if it keeps popping up when you don't want it. It's reliable at blocking <video>. ...

Open the mkv in mkvmerge, check if it has attachments and if it does, remove them, mux and try converting again. Attachments is the only thing I have encountered that cause an mkv to display as "motion jpeg" in Xmedia recode.

Standard vga means that it is not using the driver. Performance will definitely take a hit without the proper driver. You could try to manually install the driver by going to the standard vga properties then clicking update driver and just browse to the files instead of running the installer. Or possibly try to right click the driver installer and run as ...

If you're watching them in Firefox, you can zoom in.  Use Ctrl++ (which, strictly speaking, is Ctrl+Shift+= on most keyboards) to zoom in (i.e., enlarge), Ctrl+- to zoom out (i.e., shrink), and Ctrl+0 (zero) to reset.  Or you can use the "View" → "Zoom" menu to achieve the same results.  You can do the same thing in Internet Explorer (it lets you zoom ...

There can be hardware issues, video and audio renderers failing due to the hardware or driver's inability to support a particular colorspace or audio format. Some players allow you to switch renderers to get around these issues, Zoom Player for example.

I just ran into this same error message "Impossible to open..." with a doubled path. I eventually figured it out. The issue is that the paths listed within your text file are interpreted by ffmpeg as being relative to the location of your text file. (In particular, the paths listed are not relative to the current working directory.) Thus, for example, if ...

I just ran into similar error messages. I eventually figured it out. There were two issues. Issue 1: When doing ffmpeg -f concat -i <path_to_text_file> ... the path_to_text_file must use forward slashes, not backslashes, even in Windows. This rule doesn't seem to apply for the video file paths on the command line though -- only for the text file ...

You can also open all of the files in VLC. It will play the videos automatically, but press stop in the lower left (the square symbol) and it will show you the playlist. At the top of the playlist it will have the total duration. If you enable the correct columns (right click on a column header and check the appropriate boxes), it will give the name, file ...

No you cannot download parts to reassemble, of a normal video download that is only encoded in one res, or a stream that has only one res available. The files are compressed/encoded/animated and pulling down parts and pieces of the whole would just be a jumbled up mess. It would have to be decoded first, (in most cases) then parts of the whole could be ...

Your best bet would be a professional video editor such as Adobe Premiere, but you specified freeware, so I direct you to a favourite of mine: ffmpeg or avconv. (It's the same program, basically. The kind people in the comments might be able to help clarify which one is available for Windows 7. I use avconv because that's the one in my Debian repository, but ...

Yes. What you will need to do is "dynamic range compression", followed by an overall boost of volume level do bring the peaks back up to 0dBFS. Any of a large number of sound editing programs can do this. Audacity (free) simply calls the tool "Compressor" and it does have the gain compensation feature. Here's their help page: ...

This is a bit hacky, but you can use any scripting language (e.g., Ruby) to generate a random list of split times. Just change the total duration (150 here) and then assign the output of that script to the option -segment_times $ times=$(ruby -e 's=[]; d=0; while d < 150 do t=rand(15..50); s << (d+t); d=d+t end; puts s.join(",")') $ echo $times ...

The YouTube Flash Player extension for Firefox or Chrome will allow that. A very lightweight add-on that forces YouTube to play videos using Flash Player because it consumes less material resources (CPU, RAM) and offers more resolution choices than the HTML5 Player.

I would use blender to accomplish this. A quick search for "blender picture-in-picture" came up with this tutorial that outlines the necessary steps.

Unless you have a WiDi capable TV and a WiDi capable WiFi adapter, streaming a desktop to a TV is never going to be possible. This is because Display over WiFi, or WiDi uses a special protocol (and special hardware) to stream or broadcast your PCs desktop, much like a RTMP stream requires software to be able to grab that stream

Although I have been unable to find a direct solution to the problem when streaming, I have found a workaround that fixes the issue on streamed videos that have the problem. To resolve the issue, use VLC Media Player to stream the video to an MP4 file. When starting the stream, make sure that on the Transcoding Options page, you click the wrench and check ...

The latest Intel drivers have a registry key to simulate memory.

I've used the trial version of Camtasia by Techsmith in the past. Depending on how long this project is going on, or how long you will need the software, this could be a viable option. If you're just producting the one video, the trial period is free and it's a very good program for editing videos like that.

Well, I have a few pieces of advice.

Your idea for making video playback smoother by means of what you call linear interpolation is simply a blend method of frame rate conversion (or Blend FRC). MediaPlayer.NET (MPDN) employs this technique and calls it "Fluid Motion". madVR calls it "Smooth Motion". This method of FRC is the most basic of what SVP uses. However, both MPDN and madVR have the ...

FFmpeg does not have a direct way to get this done. What you can do is split the video into slices, apply the slow motion to each slice and concatenate all together again. filter_complex can be used with filter chaining for this. ffmpeg -i input_video -filter_complex " [0:v]trim=0:10[v1]; [0:v]trim=10:30[v2]; [0:v]trim=start=30[v3]; ...

Yo must match slide aspect ratio with screen ratio. Thus, if your screen is 16:9 so does the slide should be. The problem with this is that graphics and images will get stretched. In order to prevent it you must manually Lock aspect ratio (right click, Size and Position, check the box). You can do this after stretching too, but it requires tweaking the Scale ...

Here's what I'd suggest: If you're able to test the output sync of your camera by using a raspvid preview window and you find the camera to be lagging behind, then I'd say the camera's h264 encoder is to blame. If it's in sync, however, then FFmpeg is doing a number on the piped input. If the camera's h264 encoder is the problem and the video lag behind the ...

Your two inputs seem to be the same file (2.mp4); so you can do a bitstream copy as mentioned on the documentation page on Concatenating videos as the codec parameters will match: file concat.txt: file '/full/path/to/2.mp4' file '/full/path/to/2.mp4' and then use the command: $ ffmpeg -f concat -i concat.txt -c copy out.mp4 However, you will have to ...

Your friend is right- ffmpeg only cuts at keyframes when doing a stream copy. If you transcode, you can do a frame-exact copy; for example: $ ffmpeg -i source.mkv -ss 01:02:37.754 -map_chapters -1 -c:v libx264-c:a copy -crf 18 -t 00:04:52.292 output.mkv Change the value for crf to suit your quality. Do note that since this is a transcode it will take much ...

ffmpeg -i in.mp4 -c copy -metadata:s:v:0 rotate=90 out.mp4 That's worked for me but not work all video player. But it is so fast than other commands. It just change the rotate flag. (Note special angle can't work with this).


1

The reason it's slow is not because of the rotation, it's because you reencode the video. When you don't specify an output video codec, the default for mp4 is H.264 (libx264) preset medium, which depending on the resolution and your hardware, can be slow. I see you try to go around that by specifying "-c copy", but you can't : rotating the video means ...

I'm suggesting rotate instead of transcode. ffmpeg -i input_video -vf "rotate=PI/2" output_video Also see here and here for more information. Hope this helps!

The -itsoffset option should do what you want: -itsoffset offset (input) Set the input time offset. offset must be a time duration specification, see (ffmpeg-utils) the Time duration section in the ffmpeg-utils(1) manual. The offset is added to the timestamps of the input files. Specifying a positive offset means that the corresponding ...

My approach would be two separate commands, one to calculate the dimensions and another to overlay. You can simply use FFprobe which comes alongside with FFmpeg. To calculate the dimensions you can use the following command. ffprobe -v error -show_entries stream=width,height -of default=noprint_wrappers=1 input_video This will result like following. ...
