Hi, When I record from v4l2 in debug mode, I get no error message, only green lines. ./ffmpeg -debug 1 -f pulse -ar 44100 -ac 2 -channel_layout stereo -thread_queue_size 1024 -i alsa_input.pci-0000_00_14.2.analog-stereo -f v4l2 -use_wallclock_as_timestamps 1 -itsoffset 1.69 -channel 1 -video_size 720x576 -pix_fmt yuyv422 -thread_queue_size 1024 -i /dev/video0 -c:a pcm_s16le -channel_layout stereo -c:v ffv1 -level 3 -g 1 -aspect 4:3 -pix_fmt yuv422p -top 0 -vsync passthrough /Store3/Test/t_`date +%Y%m%d_%H%M`.mkv
Then when I run the following command on the file I get a lot of same errors in red. Are these errors recorded in the file or are they generated when reading? ./ffmpeg -i /Store3/Test/t_20151129_1015.mkv -f null /dev/nullffmpeg version N-76674-g7ad698e Copyright (c) 2000-2015 the FFmpeg developers built with gcc 5.1.1 (GCC) 20150618 (Red Hat 5.1.1-4) configuration: --enable-libpulse --enable-gpl --enable-libx264 libavutil 55. 6.100 / 55. 6.100 libavcodec 57. 15.100 / 57. 15.100 libavformat 57. 14.100 / 57. 14.100 libavdevice 57. 0.100 / 57. 0.100 libavfilter 6. 15.100 / 6. 15.100 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.101 / 2. 0.101 libpostproc 54. 0.100 / 54. 0.100 Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, matroska,webm, from '/Store3/Test/t_20151129_1015.mkv': Metadata: ENCODER : Lavf57.14.100 Duration: 00:03:01.33, start: 0.000000, bitrate: 37498 kb/s Stream #0:0: Video: ffv1 (FFV1 / 0x31564646), yuv422p, 720x576, SAR 16:15 DAR 4:3, 25 fps, 25 tbr, 1k tbn, 1k tbc (default) Metadata: ENCODER : Lavc57.15.100 ffv1 DURATION : 00:03:01.200000000 Stream #0:1: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/s (default) Metadata: ENCODER : Lavc57.15.100 pcm_s16le DURATION : 00:03:01.325000000 Output #0, null, to '/dev/null': Metadata: encoder : Lavf57.14.100 Stream #0:0: Video: wrapped_avframe, yuv422p, 720x576 [SAR 16:15 DAR 4:3], q=2-31, 200 kb/s, 25 fps, 25 tbn, 25 tbc (default) Metadata: DURATION : 00:03:01.200000000 encoder : Lavc57.15.100 wrapped_avframe Stream #0:1: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s (default) Metadata: DURATION : 00:03:01.325000000 encoder : Lavc57.15.100 pcm_s16le Stream mapping: Stream #0:0 -> #0:0 (ffv1 (native) -> wrapped_avframe (native)) Stream #0:1 -> #0:1 (pcm_s16le (native) -> pcm_s16le (native)) Press [q] to stop, [?] for help [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 131 >= 131 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 173 >= 173 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 210 >= 210 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 817 >= 817 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 836 >= 836 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 849 >= 849 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 868 >= 868 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 881 >= 881 [null @ 0x3101c20] Application provided invalid, non monotonically increasing dts to muxer in stream 0 ... and more _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
