I'd like to encode a HD camera(720p) to local file with x264(bitrate = 3000kb,keyint=25,mux=ts), and play it seconds later while still encoding. but i found that the file always 0 kb long until I stopped recording. it seems that the x264 encoder buffered all the encoded frame in memory and wrote to ...

thank you so much!

i streams a camera to local file with code below: m = libvlc_media_new_location (inst, "dshow://"); CStringA opt_out_str; opt_out_str.Format(":sout=#transcode{width=640,height=480,vcodec=h264,vb=800,scale=1,fps=25.1f,acodec=aac,ab=128,channels=2,samplerate=44100} :duplicate{dst=std{ac...

can anyone help me?

even in VLC

when i transcoding or recording or streaming a video to internet, it can't display locally .
i tried "duplicate{dst=display,dst=...}",it doesn't work,the display is freezen ,but still can recording or streaming.
is it a bug ? or i didn'e do the right?

set gop to a small value like 12 would make it better; gop=12 provides a 12/fps second Accuracy。

it's absolutely possible,but difficult. it depends on video format a lot. ffmpeg provides a function seek by frame ( av_seek_frame),but i have not tried; in vlc,you can calculate the specific frame's time stamp and set_time to the nearest key frame,then get next frame until the time stamp is the nea...

try
:duplicate{dst=std{access=file,mux=ts,dst=C:\test.mpg}}

it is not easy especially when the frame is not a key frame. you should jump forward and decode.
unfortunately vlc do not provide such functions so you should write by yourself.

the length of the video can be read from time-changed-event of the libvlc_media_player_t object which recording ;the current playing time can also be read if you open the file few seconds later;
now i open the increasing file by ffmpeg and can easily get the timestamp.

the VLC can play increasing (still recording) ts file,and can get the current length of the video,and also know how long time the player played. but when i play a increasing ts file with libvlc, it works ,but can not provide current time in time-change event,it returns 0 both in libvlc_media_player_...
