avconv much longer than ffmpeg
18 mars 2014, par fsulserI was using ffmpeg to generate some images from a video. Now I read that I shouldn't use ffmpeg longer and use avconv from libav instead.
So I tried to do the same thing with avconv.The ffmpeg is looking like this :
ffmpeg -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp
Same with avconv :
avconv -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp
ffmpeg needs less than one second to finish. Avconv about 90 seconds for the same task.
Is this usual or do I need to change some things to work with avconv ? -
Encoding video only FLV
25 mars 2012, par NadavRubI am trying to generate a video only FLV file, I am using :
- libx264 + ffmpeg
- 30 fps ( fixed )
- playback is done using VLC 2.0.1 and flowplayer
When playing the FLV the frame-rate seems 1 frame per sec, following is the way I cfg ffmpeg :
AVOutputFormat* fmtOutput = av_oformat_next(0);
while((0 != fmtOutput) && (0 != strcmp(fmtOutput->name, "flv")))
fmtOutput = av_oformat_next(fmtOutput);
m_pFmtCtxOutput = avformat_alloc_context();
m_pFmtCtxOutput->oformat = fmtOutput;
AVStream* pOutVideoStream= av_new_stream(m_pFmtCtxOutput, pInVideoStream->id);
AVCodec* videoEncoder = avcodec_find_encoder(CODEC_ID_H264);
pOutVideoStream->codec->width = 640;
pOutVideoStream->codec->height = 480;
pOutVideoStream->codec->level = 30;
pOutVideoStream->codec->pix_fmt = PIX_FMT_YUV420P;
pOutVideoStream->codec->bit_rate = 3000000;
pOutVideoStream->cur_dts = 0;
pOutVideoStream->first_dts = 0;
pOutVideoStream->index = 0;
pOutVideoStream->avg_frame_rate = (AVRational){ 30, 1 };
pOutVideoStream->time_base =
pOutVideoStream->codec->time_base= (AVRational){ 1, 30000 };
pOutVideoStream->codec->gop_size = 30;
%% Some specific libx264 settings %%
m_dVideoStep = 1000;// packet dts/pts is incremented by this amount each frame
pOutVideoStream->codec->flags |= CODEC_FLAG_GLOBAL_HEADER;
avcodec_open(pOutVideoStream->codec, videoEncoder);The resulting file seems OK, with the exception of the playback frame-rate.
having in mind that :- pOutVideoStream->avg_frame_rate = (AVRational) 30, 1 ;
- pOutVideoStream->time_base = (AVRational) 1, 30000 ;
- pOutVideoStream->codec->time_base= (AVRational) 1, 30000 ;
- For each frame I increment the dts/pts by 1000
What am I doing wrong here ? why the file is playing choppy ( 1 fps ) ?
Any help will be appreciated.
