[Cin] mpeg2hd422p.m2ts - groundwork for a high-end preset
While the newer h.264 and hevc are known for best compression, mpeg2 may have better quality at video bitrate > 30Mbps This example capture a raw video stream (optional tape playback) from the camera sensor over HDMI out and transcode audio to PCM into a high-end mpeg2hd422p.m2ts -input_format yuyv422 -video_size hd1080 possibly may be commented out, as the encoder default uses the maximum capability it get from the capture card ms2130 and driver v4l2 mpeg2video is difficult to get quit perfect with ffmpeg; muxing overhead: 6.206455% is the minimum I have achieved as in this case. At this high bitrate, 39Mbps here, a combination with segmented recording is suggested and preferred to control the file sizes (segments) and eventually corrupted parts better. ffmpeg -hide_banner -f v4l2 -framerate 50 -i /dev/video0 -f alsa -ac 2 -i hw:CARD=UHD,DEV=0 -c:v mpeg2video -refs 1 -bf 2 -b:v 35M -maxrate 35M -minrate 35M -bufsize 38M -muxrate 38M -dc 10 -c:a pcm_bluray -mpegts_m2ts_mode 1 -t 30 -f mpegts mpeg2hd422p_35M.m2ts Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 79.422429, bitrate: 1658880 kb/s Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1920x1080, 1658880 kb/s, 50 fps, 50 tbr, 1000k tbn [aist#1:0/pcm_s16le @ 0x55e2664e95c0] Guessed Channel Layout: stereo Input #1, alsa, from 'hw:CARD=UHD,DEV=0': Duration: N/A, start: 1749208971.359170, bitrate: 1536 kb/s Stream #1:0: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> mpeg2video (native)) Stream #1:0 -> #0:1 (pcm_s16le (native) -> pcm_bluray (native)) Press [q] to stop, [?] for help [mpeg2video @ 0x55e2664d0500] Warning vbv_delay will be set to 0x (=VBR) as the specified vbv buffer is too large for the given bitrate!
