[Libav-user] statically linking x264 and x265 into ffmpeg

Hi to all, for a project, I'd like to bundle ffmpeg statically. The project itself is cross-platform, which is proving to be a challenge. For this, I'd like to build ffmpeg statically and link in libx264 and libx265 so that I only have to link my library in turn to ffmpeg and be done with

Alright, so this ``` ./configure --prefix=/tmp/ffmpeg --disable-programs --enable-pic --enable-static --enable-libx264 --enable-libx265 --enable-gpl --extra-ldflags="/home/steinbac/software/x264/master-static/lib/libx264.a /home/steinbac/software/x265/master-static/lib/libx265.a" ```

Re: [Libav-user] Getting a Frame question

Yes I need to call av_write_trailer, but I am getting an error with avformat_write_header which is: "Invalid data found when processing input" What causes that? 06.09.2016, 01:19, "Leandro Raffo" : > Dont you need to call av_write_trailer at the end? > > 2016-09-05 18:42

[Libav-user] Adjust fps

I'm trying to remux a video changing its frame rate, but I'm a bit lost in how to do it. This is what I have in mind: Suppose I have a 20 fps video and I want to take it for example to 10 fps, should I drop every second frame (paket) and JUST multiply the dts and pts by 2. What if I want to go 3

[Libav-user] Sampling parts of a video on packet level

Hi, I am working on a remote application that is using OpenCV to detect a ball in a video stream. I have a need to monitor how its doing from home, and therefore need access to source video and the detections found. The system is unfortunately behind limited bandwith connection so I am forced to

[Libav-user] failing decoding with certain wma files

I'm trying to build a small universal audio decoding library that decodes the file a frame at a time (on Android platform). I've built a command line static ffmpeg that I can exec that works on every file format I have tested. Now I am trying to build a shared library version, so I can directly

[Libav-user] How to achieve 30 FPS using APIs?

We have seen that using command line, ffmpeg is capable of extracting frames at 30 fps. Even using Xuggler, we are able to extract frames at 30 fps. But when we use FFMPEG APIs directly in our code, we are getting following results: - 720p video (1280 x 720) - 16 fps (approx. 60 ms/frame)
