La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

Cannot merge VisualSampleEntry error while appending videos in MP4parser
13 août 2021, par Abhishek IppakayalI am creating four videos with ffmpeg and then i am appending them with MP4parser.
Details of four videos that i am creating with ffmpeg.


- 

- 1,2 video : created using one image




[-loop, 1, -i, Count_1627453922.jpg, -s, 720x1280, -vf, format=yuv420p,fps=25,fade=type=in:duration=1,fade=type=out:duration=1:start_time=1, -t, 2, -preset, ultrafast, CountImageVideo_1627453922.mp4]


- 

- 3,4 video : trimming 3 second video from an existing mp4 video




[-i, footages_5_1624263519549.mp4, -ss, 00:00:00, -to, 00:00:02, -s, 720x1280, -r, 25, -preset, ultrafast, One_1627453926.mp4]


Now i am trying to append all these videos with MP4Parser and getting below error :


java.io.IOException: Cannot merge VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@f3f76444] and VisualSampleEntry[com.googlecode.mp4parser.boxes.mp4.ESDescriptorBox@e20a2ed0]
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.mergeStsds(AppendTrack.java:116)
 at com.googlecode.mp4parser.authoring.tracks.AppendTrack.<init>(AppendTrack.java:59)
</init>

I have done some debugging and found something that can help understand error better.
Sample Description boxes of two videos


Two video tracks have different formats (MP4v & AVC1). I am new to ffmpeg and MP4parser so did not getting what i am doing wrong. Thanks ! in advance.

After ffmpeg encode, AVPacket pts and dts is AV_NOPTS_VALUE
29 novembre 2017, par Li ZehanI would like to ask a question about ffmpeg when i use encoder (x264).
this is my code :
int
FFVideoEncoder::init(AVCodecID codecId, int bitrate, int fps, int gopSize,
int width, int height, AVPixelFormat format) {
release();
const AVCodec *codec = avcodec_find_encoder(codecId);
m_pCodecCtx = avcodec_alloc_context3(codec);
m_pCodecCtx->width = width;
m_pCodecCtx->height = height;
m_pCodecCtx->pix_fmt = format;
m_pCodecCtx->bit_rate = bitrate;
m_pCodecCtx->thread_count = 5;
m_pCodecCtx->max_b_frames = 0;
m_pCodecCtx->gop_size = gopSize;
m_pCodecCtx->time_base.num = 1;
m_pCodecCtx->time_base.den = fps;
//H.264
if (m_pCodecCtx->codec_id == AV_CODEC_ID_H264) {
// av_dict_set(&opts, "preset", "slow", 0);
av_dict_set(&m_pEncoderOpts, "preset", "superfast", 0);
av_dict_set(&m_pEncoderOpts, "tune", "zerolatency", 0);
m_pCodecCtx->flags |= CODEC_FLAG_GLOBAL_HEADER;
m_pCodecCtx->flags |= AV_CODEC_FLAG_GLOBAL_HEADER;
}
int ret = avcodec_open2(m_pCodecCtx, m_pCodecCtx->codec, &m_pEncoderOpts);
if (ret == 0) {
LOGI("open avcodec success!");
} else {
LOGE("open avcodec error!");
return -1;
}
return ret;
}
int FFVideoEncoder::encode(const Frame &inFrame, AVPacket *outPacket) {
AVFrame *frame = av_frame_alloc();
// avpicture_fill((AVPicture *) frame, inFrame.getData(), AV_PIX_FMT_YUV420P, inFrame.getWidth(),
// inFrame.getHeight());
av_image_fill_arrays(frame->data, frame->linesize, inFrame.getData(), m_pCodecCtx->pix_fmt,
inFrame.getWidth(), inFrame.getHeight(), 1);
int ret = 0;
ret = avcodec_send_frame(m_pCodecCtx, frame);
if (ret != 0) {
LOGE("send frame error! %s", av_err2str(ret));
} else {
ret = avcodec_receive_packet(m_pCodecCtx, outPacket);
LOGI("extract data size = %d", m_pCodecCtx->extradata_size);
if (ret != 0) {
LOGE("receive packet error! %s", av_err2str(ret));
}
};
av_frame_free(&frame);
return ret;
}I expect that the AVPacket will carry the pts and dts about this frame.
but in fact, i only can get encoded frame data and size.
//====================================
except this question, i have another quesiont :
x264 docs say that "tune" opts can be set like film、animation and others. but i only can get a normal video when i set "zerolatency" params. When i set others opts, video’s bitrate is very low.
Thanks your answer.

FFMPEG disabled automatic compression file
2 novembre 2017, par HenrykVIIIHow to disable FFMPEG in its own compressed file compression, which does not come from the program code. This is when the file is merged (as the first task) or file stabilization (as the first task). I lose on file quality by reducing itself from 16k to 7k birate files (in parts) input.
So, without loss, I have to merge files or stabilize them so that they do not change ?
I will add that the effect does not affect every film - only the majority. None of which come out of a duel completely and eg for 16.2k input birate have output 16k birate .. What is no visible loss.
But the loss from 16k to 7k is already visible on the details and especially the movies shot at night and in the wrong light.
I enclose the wrapper code c # :
The same situation occurs when the first task is to combine files :Can anyone help ?? : (((
