Audio out of sync after many Non-monotonous DTS in output stream warning
by Yang Zhang 02 Feb '21

02 Feb '21

when I transcoding some live stream that comes from DVB, I got many warnings bellow and after a few hours, the audio out of sync. [tee @ 0x2998780] Non-monotonous DTS in output stream 0:0; previous: 27931, current: 27929; changing to 27932. This may result in incorrect timestamps in the output file. [tee @ 0x2998780] Non-monotonous DTS in output stream 0:0; previous: 27935, current: 27933; changing to 27936. This may result in incorrect timestamps in the output file. And here is the ffmpeg command we used. Any suggestions for how to solve the audio out of sync issue? ffmpeg -vsync passthrough -copytb 1 -hwaccel cuvid -hwaccel_device 3 -probesize 10000000 -analyzeduration 10000000 -c:v h264_cuvid -gpu 3 -deint adaptive -drop_second_field 1 -fifo_size 713924 -overrun_nonfatal 1 -buffer_size 67108864 -i udp://127.0.0.1:48210 -filter_complex [0:i:0xab]split=outputs=1[map:v:0] -map [map:v:0] -c:v:0 h264_nvenc -g 250 -flags:v +global_header+cgop -preset:v medium -profile:v:0 high -gpu 3 -b:v:0 3500k -maxrate:v:0 5000k -bufsize:v:0 10000k -map 0:i:0x92 -c:a:0 aac -ac 2 -ar 44100 -b:a:0 128k -metadata service_name="LA 1 HD" -metadata service_provider="Movisrta+" -max_muxing_queue_size 512 -f tee [select=\'v:0,a:0\':bsfs/v=dump_extra=freq=keyframe:f=hls:hls_time=5:hls_list_size=10:hls_flags=delete_segments:var_stream_map=\'v:0,a:0\':hls_segment_filename=cache/hls /2/playlist_%v_%d.ts]cache/hls/2/index.m3u8

Calculating output dimensions to avoid conflicting stream par values in Adaptation Set
by Richard Hristov 02 Feb '21

02 Feb '21

Hello, I'm working on a service which handles transcoding user generated videos in order to host them as VODs on the web. The service uses ffmpeg to transcode the videos and I have recently been working on adding dash/hls support to enable the videos to start up faster and handle multiple bandwidth situations. ffmpeg's dash output format with hls enabled seems to work well enough for this purpose, however I have ran into an issue for which I can't figure out a fix. The input videos have a wide range of formats and dimensions, which causes trouble when using multiple inputs at different dimensions. I currently prepare my input streams by fixing their smaller dimension to a certain size and letting the other one be auto generated to preserve aspect ratio using the scale filter, like so: -filter:v "scale=-2:720"; This is done for multiple "targets" such as 1080p, 480p etc. If the video is using an aspect ratio of 16/9, this works fine. However, certain aspect ratios will cause the dash command to fail with the error "Conflicting stream par values in Adaptation Set". For example, I've had a user upload a video with the dimensions 1920x1012, this aspect ratio is the fraction 227/253 and in this case ffmpeg's scale filter calculated the following outputs: 684x360, 888x468, 1366x720. Since all of these are a different fraction than the source, ffmpeg compensates by setting the sar and dar to avoid distortion, however it will then fail at the dash/hls stream generation step. How would I go about fixing this issue for all input dimensions? Is it possible to force ffmpeg to transcode to outputs which conform to the same aspect ratio so that the dash/hls step doesn't fail? Here are the ffmpeg commands which cause the issue: ffmpeg -i "" -c:v libx264 -crf 23 -fs 1073741824 -preset faster -maxrate:v 350k -bufsize:v 700k -filter:v "scale=-2:360" -map 0:v:0 -c:a aac -b:a 128k -map 0:a:0 -dn -sn -y 1.mpd_360.mp4 ffmpeg -i "" -c:v libx264 -crf 23 -fs 1073741824 -preset faster -maxrate:v 650k -bufsize:v 1300k -filter:v "scale=-2:468" -map 0:v:0 -c:a aac -b:a 128k -map 0:a:0 -dn -sn -y 1.mpd_468.mp4 ffmpeg -i "" -c:v libx264 -crf 23 -fs 1073741824 -preset faster -maxrate:v 1300k -bufsize:v 2600k -filter:v "scale=-2:720" -map 0:v:0 -c:a aac -b:a 128k -map 0:a:0 -dn -sn -y 1.mpd_720.mp4 ffmpeg -sn -dn -i 1.mpd_360.mp4 -sn -dn -i 1.mpd_468.mp4 -sn -dn -i 1.mpd_720.mp4 -map 0 -map 1 -map 2 -c:a copy -c:v copy -use_timeline 1 -use_template 1 -adaptation_sets "id=0,streams=v id=1,streams=a" -hls_playlist true -f dash -y 1.mpd The input's dimensions are 1920x1012. The ffmpeg website has an example command to generate a dash stream which does this all in a single command but it will then be unable to handle variable bitrate and it will write completely bogus bitrates to the dash and hls manifests, so I used multiple commands instead and I generated the manifests after the individual streams have finished transcoding. Thanks for the help in advance Richard Hristov

Subtitle Error - Suggestion
by Jim 01 Feb '21

01 Feb '21

I recently made a video that I wrote subtitles for - my first time writing them myself. When I tried to burn them into the video using ffmpeg, it gave me the following: [Parsed_subtitles_0 @ 0x554ed40] Shaper: FriBidi 1.0.1 (SIMPLE) [Parsed_subtitles_0 @ 0x554ed40] Unable to open comments.srt [AVFilterGraph @ 0x5528140] Error initializing filter 'subtitles' with args 'comments.srt:force_style=Fontsize=26' Error reinitializing filters! Failed to inject frame into filter network: Invalid data found when processing input Error while processing the decoded data for stream #0:0 After pulling my hair out trying to figure out why it couldn't find comments.srt when it was plainly right there, I gave up & tried a different tool. It told me that there was an error in the SRT file structure. Sure enough, I'd forgotten to include the milliseconds: 1 00:00:31 --> 00:00:35 My text was here. was supposed to be 1 00:00:31,000 --> 00:00:35,000 My text was here. After I added ,000 to every timestamp in the SRT file, ffmpeg worked perfectly. My suggestion is simple - instead of having ffmpeg report that it is unable to open the file, make it say something like 'invalid subtitle structure' or 'fix your subtitle file stupid'. ;) Really, just change the wording to be something relevant to what is wrong in order to make it easier to figure out what's wrong.

co64 atom in QT / Mp4, and compatibility with Premiere
by Bouke 01 Feb '21

01 Feb '21

This is not an FFmpeg question perse, but I hope someone knows more about atoms than I do. Similar to the previous thread, I am modifiying clips ‘in place / destructive’. (For .Mp4 / .mov files) For that I re-write or re-order the moov atom to needs. That all seems to work fine, if files are < 4 gig. On larger files, when I want to change TC, I add an mdat atom with the TC converted to frame number. In the TC track (That I rip from a dummy FFmpeg short transcode), I change the pointer in the TC tracks stco atom to the newly added mdat location. So far so good. Now, when the new mdat pos goes over 4 gig, I add an co64 atom so I have 8 bytes to set it, and I change the whole shebang to reflect the new length of all atoms in the structure. This also ‘sorta kinda’ works, as QT player displays the correct TC. BUT, Adobe Premiere does NOT like this, it gives me another TC that I can’t place for the life of me… If I omit the co64 atom and find ‘some’ spot (either inside an mdat atom or not), it works, but it seems Premiere totally ignores the co64 info. Can anyone shed a light on this? Thx, Bouke

minterpolate ...for Paul
by Mark Filipak (ffmpeg) 01 Feb '21

01 Feb '21

I'm seeing problems with minterpolate that manifest as occasional visual errors in particular areas. Visually, the issue looks like a math error diddling macroblocks. But there's some strangeness. The scene is a camera pan to the right and up. The strangeness appears at the top of the frame (as expected) and involves the top row of macroblocks (as expected). The strangeness is, 1, the affected area is 14x1 macroblocks (not a very explainable number), and 2, the affected area is in error by only about a half-dozen pixels (not a whole number of macroblocks). Let me know if you're interested in pursuing this. If so, I'll post the transcode video and the source video on dropbox. The videos are 20 seconds. By the way, minterpolate is amazing! Regards, Mark. -- Someone's sneaking in and turning up the range so that my food burns. I'm sure of it. And the older I get, the more sure of it I become.

No multicast request from client

I'm using this SDP-file: v=0 m=video 49550 RTP/AVP 96 c=IN IP4 239.255.50.5/127 a=rtpmap:96 H264/90000 And this command: ffmpeg.exe -protocol_whitelist rtp,udp,file -i h264.sdp I've used Wireshark to check all network-interfaces for multicast-request, but nothing happens. Since I have multiple NICs, maybe I have to specify which NIC to use, so using this command works: Fmpeg ..... -i udp://239.255.50.5:49550?localaddr=172.17.1.227 But hen, ffmpeg complains about the video-format, as it isn't specified using an SDP-file (type 96) So anyone: How to specify both SDP-file and the localaddr-option at the same time ? OS: Windows 10 /arne
