save row ffmepg data packets as a video
7 août 2019, par MattéoLuciI have modified the muxing.c ffmpeg example program to be able to save a video from the PC or on an RTSP stream, and it works quite good.
I would like to make the video saving as fast and efficient as possible by saving directly the packets without changing them into AVFrames (I don’t need to print them).I tried to save the AVPacket coming from av_read_frame(InFmtCtx, &packet) with av_write_frame(OutFmtCtx, &packet).
AVPacket packet;
static int count = 0;
while (av_read_frame(InFmtCtx, &packet)>=0) {
if(packet.stream_index == videoStream) {
packet.dts = count;
packet.pts = count++;
av_packet_rescale_ts(&packet, ost->enc->time_base,
ost->st->time_base);
packet.stream_index = ost->st->index;
if (av_write_frame(OutFmtCtx, &packet) < 0) {
fprintf(stderr, "Error writing video frame: \n");
exit(1);
}
ost->enc->frame_number++;
}
}The program runs correctly and the video file has the right size and the right duration.
When I run it with VLC or ffmpeg it shows no error message, the time runs correctly, but no image is printed -
using ffmpeg to process webcam data and save it in multiple files
21 septembre 2017, par Deepak NellurvalappilI am trying to process streaming video data from a usb webcam using ffmpeg. the process involves encoding the raw data into hevc format. Upto this point I am able to do.
But now, I want to slice the processed data in chunks of 10 seconds and save it in a separate file. This should repeat until I kill/interrupt the process manually.ffmpeg -i /dev/video1 -f segment -segment_times 10 -c:v hevc cam_1_%02d.mp4
the above code does create multiple files but only the first file is readable using vlc ; other files look corrupt.
And while I was running the command, I could see the following messages :-
Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264)) Press [q] to stop, [?] for help Past duration 0.601555 too largeN/A time=00:00:14.63 bitrate=N/A dup=11 drop=0 Past duration
