FFmpeg not decreasing
19 avril 2018, par DavidI need
ffmpegto transform a video stream into images and reduce their size only if they don’t fit in a 1000x1000 box.My issue is that if the image is smaller, ffmpeg increases the size of the image to 1000 in width or height, whereas I don’t want small images to be upscaled. The
force_original_aspect_ratio=decreasedoes not seem to work here. Any ideas why ?Here is my shell command :
ffmpeg -i 'rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov' -r 5 -vf scale=w=1000:h=1000:force_original_aspect_ratio=decrease -f image2 -qscale:v 1 ./output_%01d.jpg -
how do I set speed rate (ex:double speed) in FFmpeg library ?
19 avril 2018, par geeeekI’m working on rtsp live video from ffmpeg and rendering it on the screen.
However, the image is displayed after 1 to 2 seconds.
to reduce video delay, So I want to increase the playback speed in my program.
int64_t duration = m_formatCtx-> duration;
duration = duration * 1000;
av_seek_frame (m_formatCtx, m_videoStream, duration, AVSEEK_FLAG_ANY);
av_seek_frame (m_formatCtx, m_audioStream, duration, AVSEEK_FLAG_ANY);
while (av_read_frame (m_formatCtx, & m_packet)> = 0)I can not get the result I want in this way.
