I understand that you can use ffmpeg to serve a sequence of images as video, while the images are being generated. Is this correct? Is there exists a way, where the ffserver can be used to serve a rtsp stream, using a list of mp4 files, which are getting generated sequentially (one at a time) ...

When recording my video, I recorded at a rate of 1000fps and the video turned out to be 2m...

I have been trying to figure out how to rotate videos with FFmpeg for some time now. I am working with iPhone videos taken in portrait mode. I know how to determine the current degrees of rotation using MediaInfo (excellent library, btw) but I'm stuck on FFmpeg now. From what I've read, what you need to use is a vfilter option. Accordin...

There are many different colour conversions to YUV but they all have different results! Which one is officially correct? This is the output from my test program. I have input R=128 G=50 B=50 (max value is 255). The table shows the converted YUV values, and the re-converted RGB values (which don't match the original). ./ColourConversion...
My C++ application receives a H.264 RTP video stream. Right now it decodes the stream, saves it into a YUV file and later I use ffmpeg to re-ecode the file into something suitable to watch on a Windows PC (eg. Mpeg4 AVI). Shouldn't it be possible to save the H.264 stream into a AVI (or similar) container without having to decode and re...

I want to use Python to convert a wav file to ogg vorbis format, so it can be streamed to a browser for playback. I've been able to use PyMedia 1.3.7.3 to encode to mp3 format, but when I set the output stream type to 'ogg', I get the error: oggvorbis_encode_init: init_encoder failed and the script dies. Perhaps I don't have the right ...

I've checked numerous solutions from stackoverflow, nothing seemed to work. Can someone, please post ...
Hello, I'm trying to determine the real type of a file programmatically. It seems I have to use for example FFMPeg for that. I want to determine if an uploaded file is in fact a MP4 or FLV (for flash videos) [or WebM (for HTML5)]. I know the -i operator in FFMPeg but I don't know what to check for. For example: Input #0, flv, from ...
