Description

I'm trying to transcode different video types to TS MPEG2 video and FFMPEG creates stuttering video with some files (some are okay say about 20% are stuttering).

Since the files are too big to attach (each 60MB) I've uploaded them and including the links to the 2 files below:

COMMAND:

ffmpeg -i "test1.wtv" -vcodec mpeg2video -sameq -an test.ts

Could this be related to #1302 maybe?

Replying to neufeind:

Could this be related to #1302 maybe?

Ticket #1302 was a mpeg2video regression that I believe could not be described as "stutter".

If you see a problem with current FFmpeg, please open a new ticket including your ffmpeg command line together with complete, uncut console output and provide a sample.

comment:3 in reply to: ↑ description Changed 5 years ago by cehoyos

Replying to ramitbhalla:

ffmpeg -i "test1.wtv" -vcodec mpeg2video -sameq -an test.ts

This needs -r 25.

ffmpeg -i "test2.ts" -vcodec mpeg2video -sameq -an test1.ts

I would expect there is a performance problem when playing the resulting file, at least that is what I see here on old hardware, it disappears if I reduce the resolution or play with half speed.

In the future, please do not report two unrelated problems in one bug report, it makes tracking bugs impossible.

comment:4 follow-up: Changed 5 years ago by ramitbhalla

I don't think this is a performance issue. I'm using an iCore7 system running Windows 7 and 4GB RAM with nothing running in the background.

I don't understand why -r 25 is required? (can you help me understand the logic behind how you diagnosed it and what signs I should for in future).

Did you test with reduced resolution or with reduced playback speed?

I don't understand why -r 25 is required? (can you help me understand the logic behind how you diagnosed it and what signs I should for in future).

1481 frames duplicated of 2888 frames overall is a good indication that the automatic frame rate choice was bad.

comment:6 follow-up: Changed 5 years ago by ramitbhalla

Is adding the -r 25 to the command parameter supposed to remove the errors? I ask because I'm getting the exact same output.

(Which errors? You did not report any errors in this ticket afaict, you reported playback problems for two samples, one because ffmpeg set the output frame rate too high for the input file - and your test system - the second supposedly because your test system is too slow for the resulting file, you will have to test with reduced resolution to know for sure.)
No, it is supposed to set the (correct) frame rate for test.ts.

comment:8 follow-up: Changed 5 years ago by ramitbhalla

This is in reference to Test1.ts

In your previous note you had explained to me that 1481 frames duplicated of 2888 frames overall is a good indication that the automatic frame rate choice was bad.

So I put -r 25 to the command line, but I'm still getting the same output showing a lot of frames duplicated.
My question is whether this is normal - inspite of correcting the frame rate here should I still get duplicated frames?

No.

Command line and complete, uncut console output missing / You have to put -r 25 in front of the output file name.

comment:10 follow-up: Changed 5 years ago by ramitbhalla

Thanks for looking into this.

  1. How do you know what frame rate to choose? Why 25 and not 30 or 1001/1000 etc?
  2. I'm still getting the duplicated frames error (see below)

Here is the command:

ffmpeg -i "test1.wtv" -vcodec mpeg2video -sameq -r 25 -an test.ts

Here is the output:

Replying to ramitbhalla:

Mostly unrelated: Please note that -sameq does not do what you may expect and it is a bad choice when transcoding from h264 to an earlier mpeg codec (but it is a very good choice for a test).

  1. How do you know what frame rate to choose? Why 25 and not 30 or 1001/1000 etc?

I chose 25fps because the input is 25fps.

  1. I'm still getting the duplicated frames error (see below)

There is no error about duplicated frames, the reason for the information may be that video starts later than audio, do I remember correctly that the number is already appearing at the very beginning of the transcoding, not increasing later?

comment:12 follow-up: Changed 5 years ago by ramitbhalla

2 questions:

  1. What should I use place of -sameq to preserve the original quality when moving from h.264 to mpeg2?
  2. HOW did you know the input was 25 fps?? I didn't see anything in the output that said 25 fps - what am I missing?

Thanks.

I may be wrong but I don't think it is possible.
Allow me to repeat that -sameq never means same quality, it means same quantiser.

  1. HOW did you know the input was 25 fps?

I may have guessed or tried, but looking at the output you posted, I believe BBC always sends 25fps (as do all European TV providers).

comment:14 follow-up: Changed 5 years ago by ramitbhalla

:) - okay lucky guess. I did a little research, I ran the file through MediaInfo?. It returned the frame rate as 25.

The question is why is FFMPEG reporting it as 50? Should I open a separate ticket for this?

Only if you have any indication that this is not the same problem as in ticket #1065.

comment:16 Changed 5 years ago by ramitbhalla

Sounds similar - can I tag the current file and info/output to the same ticket?

comment:17 follow-up: Changed 5 years ago by ramitbhalla

Setting the frame rate doesn't appear to solve the problem. I'm attaching a dvr-ms file (this is one cut sample, others are also facing similar issues).

As you can see from the output it keeps dropping the frames. I've tried different settings with -r 24, -r 25, -r 30, -r 50, -r 60, -r 30*1000/1001, -r 60*1000/1001, -r 25*1000/1001 and none of them seem to work, it still leads to the same issues of dropping frames and the video stutters when played back.

Any idea why this is happening?

COMMAND:

ffmpeg -i "Test3.dvr-ms" -an -vcodec mpeg2video -sameq test.ts

As you can see from the output it keeps dropping the frames. I've tried different settings with -r 24, -r 25

But for some inexplicable reason you preferred not to present command line together with complete, uncut console output, instead you posted a command line that looks very similar to the original command line (and you still didn't tell me if the problem disappears if you significantly reduce the resolution or playback with half speed which would prove my original suspicion).

  1. Yes tried with a lower resolution (1024x768 - the lowest possible) and output video is still stuttering.
  1. I gave the basic commmand line and issue, here is the one with the rate adjustment and the output. This is happening with all the DVR-MS files I have.

COMMAND:

ffmpeg -i "Test3.dvr-ms" -an -vcodec mpeg2video -sameq -r 25 test.ts

Why are you not using test1.wtv?

comment:21 Changed 5 years ago by ramitbhalla

I'm trying to replicate the issues across a variety of files (real world, the users use FFMPEG to convert WTV, DVRMS and TS files) to see if the proposed fix works. The -r works great for the WTV file but it doesn't seem to work fro DVR-MS.
Am trying to figure out a long term fix/solution.

What do you mean with "lowest possible"?
I tried 320x180 and I find the video still very watchable at least for testing and I do not see any stuttering, it also works fine with 640x360. I do see stuttering with higher resolutions because my current setup cannot play 60fps movies with (for example) 960x540 or higher resolutions.

By lowest possible I mean the lowest possible supported on my workstation (iCore 7 + 4GB RAM + Nvidia Quadro 3700M with 1GB VRAM). i didn't realize you were changing the resolution while encoding.
Anyways I'm able to play 1080p video's with 60Hz (Blu Ray) on my workstation very smoothly so I don't think it's a horsepower issue.

Any ideas why the DVRMS files dropping packets and creating stuttering videos (WTV I understood were issues with the frame rate).

You do realize that only the screen counts (my PIII 500 with <1GB does support such high fps in HD because of the screen connected) and you did not describe it?

Anyways I'm able to play 1080p video's with 60Hz (Blu Ray) on my workstation very smoothly so I don't think it's a horsepower issue.

1080@60Hz is not defined for Bluray.

Any ideas why the DVRMS files dropping packets and creating stuttering videos (WTV I understood were issues with the frame rate).

I don't think FFmpeg creates stuttering videos (at least I haven't seen any indication yet).

comment:25 follow-up: Changed 5 years ago by ramitbhalla

The screen is a 1080p 42 inch LED Tv that's hooked up via HDMI. According to TV, it's reporting a playback of 1080p @ 60Hz, that's what I'm reporting here.

The real crux of the issue is why are they packets being dropped. Is it something that I'm doing wrong in the command line (as in the WTV case, actually that was an issue of FFMPEG getting a wrong frame rate for which I'll report the issue in a separate ticket/update the existing ticket) or is there an underlying issue with FFMPEG.

1st step is to curb the drop/dup packet, 2nd step would be to figure out what's really the source of the stutter - correct me if I'm wrong here.

(Frames are being dropped, I am not sure what you mean with packets.)
Because audio starts later than video in your sample file.

Okay, so this is happening with many DVR-MS files. Any how to detect and fix/workaround this?

thanks

Workaround what? The frames are dropped / duplicated initially to get A/V sync, this is intended or do I miss something?

So you're saying that it's normal for FFMPEG to drop packets to get the AV in sync? I'm confused because this is happening with every DVRMS file (received from multiple users).

I did not want to imply that FFmpeg is dropping frames because the input file is corrupted. (Did I really write this?)

With the WTV you isolated the issue to wrong FPS which was corrected manually and it fixed the problem. With DVRMS files, i'm trying to figure out if FFMPEG is able to process the files correctly or not? If every DVRMS file is dropping frames then possibly something is wrong with FFMPEG.
Is my assumption correct?

I don't think so, and please note that setting the frame rate for Test1.wtv did not "fix" the "problem" you had namely initially dropping or duplicating frames.

Okay - help me understand this, is this a bug with FFMPEG?

  1. WTV - not being able to read the frame rate
  2. DVR-MS - dropping frames

if so, do I need open a separate tickets

If not, what's the resolution to this?

Didn't you agree this looks similar to ticket #1065?

  1. DVR-MS - dropping frames

This ticket is about stuttering ts files on slow screens when encoding 60fps material, what does this have to do with dropped frames when encoding asf?

  1. Yes it is, I'll add my comments there
  2. i've opened a separate ticket for DVRMS files dropping frames.

Thanks, please mark this ticket as invalid.

  • Resolution set to worksforme
  • Status changed from new to closed

I tested Test2.ts on faster hardware now (85Hz screen) and it plays fine as does the result of:

$ ffmpeg -i Test2.ts -ab 384k -acodec ac3 -sameq out.ts

Does the original file play fine for you but the re-encoded file not? (In that case this should be analysed further.) Please re-open if this is the case.

Test2.ts is ~60fps but was originally recorded as ~24fps afaict. In the future, there will hopefully be a filter that drops the duplicated frames, as a workaround you can use -r 24, -r 25 or -r 30 but the result will not be perfect.

Yes the original files do not have any problem playing with WMP, only the converted files are facing stuttering problems.

Thanks for teh additional info - again, for my knowledge, was there anything that told you the origianl FPS (24) or was it an educated guess?
