FPS too high when saving video in mp4 container

18 janvier 2016, par theateist

When I decode frames from avi file and then decode them in x264 and save to mp4 file, the fps of the output file is always 12,800. Therefore the file is played very fast. But, when I save the encoded in h264 frames in avi format and not mp4, so the fps is as I wanted - 25.

What could be the problem?

Here the code I wrote in VS2010:

#include "stdafx.h"
#include "inttypes.h"

extern "C" {

How to enable X264 with thread for Android on Mac OS X ?

3 janvier 2016, par Jerikc XIONG

I use the following script to compile x264:

#!/bin/bash
# Based on https://github.com/yixia/x264/blob/master/build_android.sh

if [ -z "$ANDROID_NDK" ]; then
    echo "You must define ANDROID_NDK before starting."
    echo "They must point to your NDK directories.\n"
    exit 1
fi

# Detect OS
OS=`uname`
HOST_ARCH=`uname -m`
export CCACHE=; type ccache >/dev/null 2>&1 && export CCACHE=ccache
if [ $OS == 'Linux' ]; then
    export HOST_SYSTEM=linux-$HOST_ARCH
elif [ $OS == 'Darwin' ]; then
    export HOST_SYSTEM=darwin-$HOST_ARCH
fi

libx264 encode error Input picture width (40) is greater than stride (0)

27 décembre 2015, par alijandro
I used libx264 in ffmpeg to encode video, I used the configuration below.
```
enCodecContext->bit_rate = 300000;
enCodecContext->width = 80;
enCodecContext->height = 60;
enCodecContext->time_base = (AVRational) {1, 25};
enCodecContext->gop_size = 10;
enCodecContext->max_b_frames = 1;
enCodecContext->pix_fmt = PIX_FMT_YUV420P;
enCodecContext->qcompress = 0.6;
av_opt_set(enCodecContext->priv_data, "preset", "slow", 0);
```
But when I called avcodec_encode_video2 with enCodecContext, I got the error Input picture width (40) is greater than stride (0).
```
avcodec_encode_video2(enCodecContext, &filteredAVPacket, pFilteredAVFrame, &got_packet_ptr);
```
The pFilteredAVFrame->width and pFilteredAVFrame->height is 80 and 60 respectively.

Did I missed something when configured libx264, How can I get a workable configuration for libx264 to encode my video?

Android ffmpeg with libx264 - undefined references

5 décembre 2015, par Krzysztof Kansy

I'm building ffmpeg for Android with libx264 using appunite's project under Ubuntu 15.10. I've build it without libx264 properly, but adding the library keep giving me undefined reference to 'x264_picture_init' and multiple other similar errors. I tried variety of possible solutions from mailing lists/other SO questions, but still nothing helps me solving the problem.

I have removed ffmpeg/libx264/libx264-dev packages to avoid possible duplicate libraries in the system. I've got the libx264.a library in ffmpeg-build/ARCH/lib, where the other built libraries lives. Also I don't think this is caused by header file not matching the library, because the only x264.h header in the system is the one used for the library building.

Here is my build_android.sh.

echo "BUILD SUCCESS"

I've disabled the non-arm architectures for the time being. If there is any other information I can provide to help finding the problem, I will be happy to do so.

I'm wondering if the issue may be caused by something missing in the script, namely in build_one part, tho I tried to indicate the libx264.a directly in --extra-ldflags, without success.

webm to mp4 conversion using ffmpeg

2 décembre 2015, par Pavan K

When I try to convert a webm file to mp4 the output is very very choppy and it appears as if many frames have been dropped by ffmpeg

I used the following commands to convert

ffmpeg -i movie.webm movie.mp4
ffmpeg -i movie.webm -vcodec libx264 movie.mp4
ffmpeg -i movie.webm -vcodec libx264 -qscale 0 movie.mp4

All of them have the same problem. When I use ffprobe it seems to show the frames more or less properly.
