concat

I use ffmpeg.exe -f concat -i file_path_list_txt -c copy out_out.mp4 to concat for file in 1265_*; do ffmpeg -i $file -crf 30 -b:a 23k -b:v 96k -threads 3 -y 'out_'$file; done compressed video. When I play the generated video, the player shows the video length is much longer than the sum of compressed video pieces. And at the linkage between slices,the frame can play a very long time,time on the player is going on,but the frame is still. I use ffprobe to show the original video pieces and compressed video pieces. And found the original videos with same tbr,tbn,tbc , while the compressed not.

This is how my XML looks like <?xml version="1.0"?> <Nodes> <NodeA NodeAattr="123"> <NodeB NodeBattr="456"></NodeB> <NodeC> <NodeD NodeDAttr="ValueD"> <NodeE Name="ValueABC"> "555" </NodeE > <NodeE Name="ValueABC"> "666" </NodeE> </NodeD> </NodeC> </NodeA> </Nodes> If the values of the Name attribute of NodeE are same, concatenate the values of NodeE. And my final output xml has to look like <NodeA NodeAattr="123"> <NodeB NodeBattr="456"></NodeB> <NodeC> <NodeD="ValueD"> <NodeE Name="ValueABC"> "555" , "666" </NodeE > </NodeD> </NodeC> </NodeA> Please provide me with the xsl.. I am using XSLT1

So basically I wrote my little Add extension method for array types. using System; using System.Linq; public static class Extensions { public static void Add<T>(this T[] _self, T item) { _self = _self.Concat(new T[] { item }).ToArray(); } } public class Program { public static void Main() { string[] test = { "Hello" }; test = test.Concat(new string[] { "cruel" }).ToArray(); test.Add("but funny"); Console.WriteLine(String.Join(" ", test) + " world"); } } The output should be Hello cruel but funny world , but the but funny will never be concatenated within the extension method. Editing the same

i am having issue, to concat video, it looses the audio sync and audio started from previous video. i have tried below two link/so answer by Mulvya, but none of them work :( here is the code i am trying: 1: re-encode file a (1): ffmpeg.exe -i "f:\1.avi" -af apad -vf scale=1280:720 -crf 15.0 -vcodec libx264 -acodec aac -ar 48000 -b:a 192k -coder 1 -rc_lookahead 60 -threads 0 -shortest -avoid_negative_ts make_zero -fflags +genpts 01.mp4 2: re-encode file b (2): ffmpeg.exe -i "f:\2.mp4" -af apad -vf scale=1280:720 -crf 15.0 -vcodec libx264 -acodec aac -ar 48000 -b:a 192k -coder 1 -rc_lookahead 60

How to Concat two column in a select statement sql server 2005? Here is my statement Select FirstName,secondName from Table ...

My select statement returns NULL instead of FirstName .. I want to have FirstName if secondName is NULL .. SELECT FirstName + ISNULL(' ' + SecondName, '') from Table Douglas Loyo If one of your fields is numeric then you can cast it to a string as follows: SELECT FirstName + ISNULL(' ' + SecondName,

I don't care about the order of the elements. http://msdn.microsoft.com/en-us/library/system.linq.enumerable.union.aspx http://msdn.microsoft.com/en-us/library/bb302894.aspx Union removes duplicates. Concat does not. So, they produce different results if the sources either contain any items in common, or have any internal duplicates. If you can guarantee there are no duplicates, or if there are few and you don't care about having them in your output, Concat will be faster since there's no need to test each value against what has already been yielded. However, if there are many duplicates and

I tried to concatenate 2 MP3 files using the code below. I got a new file which I can play the first half of (complete first file), but the second half is silent. The length of the new file was correct. What do I do wrong? List<Byte[]> files = new List<byte[]>(); var tempfile = File.ReadAllBytes(Path.Combine(path, "1.mp3")); files.Add(tempfile); tempfile = File.ReadAllBytes(Path.Combine(path, "2.mp3")); files.Add(tempfile); Byte[] a=new Byte[files[0].Length+files[1].Length]; Array.Copy(files[0], a, files[0].Length); Array.Copy(files[1], a, files[1].Length); File.WriteAllBytes(Path.Combine(path

I have a function that produces lazy-sequences called a-function. If I run the code: (map a-function a-sequence-of-values) it returns a lazy sequence as expected. But when I run the code: (mapcat a-function a-sequence-of-values) it breaks the lazyness of my function. In fact it turns that code into (apply concat (map a-function a-sequence-of-values)) So it needs to realize all the values from the map before concatenating those values. What I need is a function that concatenates the result of a map function on demand without realizing all the map beforehand. I can hack a function for this:
