I think maybe it is because the recording time is too short. When vlc is playing, it does not have enough time to show the whole picture...Not sure what I think is right or not

Like what?

Almost like this, http://www.youtube.com/watch?v=_xPPin6qalU, but mine is like the screen is going down.

Hi,

When I open VLC, I try "Ctrl + N" and type in "Screen://" in the network dialog. Why the output is like that? Is it a bug?

THX.

Hi,

I notice that VLC uses net_Write() to write data to a file descriptor in "io.c"(src/network/), and then, read file descriptor line by line. Why not just read data from a buffer directly? What is the meaning of file descriptor here?

THX.

Dear all,

I find Youtube video can not be played by vlc-1.1.5 version on Win and Linux. But I work on this version`s source code all the time, so I can not update it. Then, how could I make it play Youtube?

THX.

Dear all,

Could you tell me whether VLC connects TCP socket by blocking or non-blocking method when it plays video by http connection?

Thanks.

Hi, I think VLC supports http streaming instead of progressive download. If the file is too large, progressive download is a good choice indeed. QucikTime is not open source, so I do not use it. I have a different question related to progressive download. I have a website that is used primarily in s...

Dear all, I want to play a video file which contains packet timestamp. In order that VLC can play it, I plan to add some codes to extract the timestamp values and delete them. Then the video format with timestamp is changed to the original and VLC can play it. I decide to modify "/modules/acces...

Dear all,

I use VLC to play a video by progressive download on Linux server. I record the frame arrival time of the video and want VLC to play the video frame by frame according to that time. So does anybody know which parts of source code I should work on?

Thanks.

Dear all, I find this material, http://wiki.videolan.org/Documentation:Play_HowTo/Format_String. I try the time code of the video in my filename prefix like this, "scene-$T-". But the scene filter does not output time code in the file name. Do those format string variables only support 0.9...

Hi, I use VLC to play an 85 seconds video. The frame rate is 12 frames/sec. Normally, with scene filter, it should output 1020 frames as the recording ratio is 1. If the video has some packet lost, I find the output only has 876 frames, but the duration is still 85 seconds. How does it happen? Does ...

You can change the scene filter frame ratio. But it is likely that your hard drive cannot cope with such a high data rate. Thanks, do you mean the "Recording ratio" item in the setting of Scene filter? Could I say that if I set Recording ratio = 1, it outputs 12 images (12 frames) and thi...

Dear all,

I use scene filter to capture the images. But I want to take the pictures as the same as video frame rate. For example, the video frame rate is 12 frames/second. When I use scene filter, it will also output 12 frames per second. How could I do it?

Thanks

remove the Vdummy part

thanks, it works

dear all, i am trying to capture the video and output data frame by frame into a local file when it is playing. does vlc have this function? i mean for example, i set the frame rate = 5 pictures/second. then, i will get 50 PNG pictures after play a 10 seconds` video and screen capture. could anybody...

Hi, I am a new hand for developing VLC. I am reading the source code of VLC and it confused me. Could anyone give me a help? The first question is where the main function is? Is /bin/vlc.c the main function? The second question is where the functions in video_output.c and display.c are called? The t...

Hi,

I find there are some files such as files.c, input.c, display.c and etc, in the directory of /src/ and /modules/. Do the functions with the same name in these two directories have any differences?

Thx.

Dear all, I want to record the video data which comes out from VLC decoder frame by frame into a data file. That means when we use VLC to play a video, it not only displays video but also generates a file which includes the video data frame by frame. Because there are too many files and functions in...

New format means the transmission time of that packet is 134 seconds. But how can VLC play this new format file. Is the data in container level? If so, the demux modules are the ones you are looking for http://git.videolan.org/?p=vlc.git;a=tree;f=modules/demux If the data is in codec level, then lo...

dear all,

i want to do some modification and improvement for VLC on Mac OS. so usually what kind of development environment should i use? Xcode or some others?

thx...

What format is it? For example, I add a time stamp for every packet. The original file of video content we download from server is like this, "...AADBCE..."; now it is like this "...AAD134BCE...". It is encoded and I need to send them to video decoder of VLC, right? New format m...
