video-conversion

I'm trying to make a video from a sequence of .jpg files using Nreco.videoconverter ffmpeg wrapper. I search for answer on this forum and topic that almost help me is http://stackoverflow.com/questions/15280199/how-to-make-a-video-file-from-images If you already have image files the best way is using special "image2" format (FFMpeg demuxer) and FFMPeg will read files directly for producing video Video can be produced in real-time with live stream conversion supported by VideoConverter. In this case "rawvideo" should be specified as input format and C# application should pass RAW bitmap bytes

I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I'm able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like: [avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000 It may have something to do with the funky format of these Real Media files: Duration: 01:28:23.42, start: 0.000000, bitrate: 448 kb/s Stream #0:0: Data: none, 32 kb/s Stream #0:1: Data: none, 192 kb/s Stream #0:2: Audio: sipr (sipr / 0x72706973),

I have started learning ffmpeg few weaks ago. At the moment I am able to transcode any video to mp4 using h264/AVC codec. The main scheme is something like that: -open input -demux -decode -encode -mux The actual code is below: #include <iostream> #include <math.h> extern "C" { # ifndef __STDC_CONSTANT_MACROS# undef main /* Prevents SDL from overriding main() */ # define __STDC_CONSTANT_MACROS# endif # pragma comment(lib, "avcodec.lib")# pragma comment(lib, "avformat.lib")# pragma comment(lib, "swscale.lib")# pragma comment(lib, "avutil.lib") #include <libavcodec\avcodec.h> #include

Need to create a video from a series of images. The video needs to have a low frame rate. This is the command I use to create the video. ffmpeg.exe -r 2 -i images/%3d.jpg -vcodec libx264 -pix_fmt yuvj420p output.mp4 The problem is that, while the video works just fine when played through a HTML5 video, it doesn't really work when the file is downloaded locally and played through either the Windows 10 default video player or even VLC (weirdly, the default video player works better). Can anyone explain why this is happening and possibly how to fix the issue? Some players, like VLC, don't like
