Description

Hi,

In response to https://ffmpeg.org/trac/ffmpeg/ticket/602 (cehoyos), I'll try to provide my experience with mpegts format.

Here is the first issue. I have 2 ffmpeg processes, the first one should send the a/v (aac+h264) to the localhost:port using udp, and the 2nd ffmpeg process should pick it up and just save to the .ts file.

This is the command line of the first ffmpeg:

ffmpeg -y -re \
        -f video4linux2 -r 30 -s qvga -i /dev/v4l/by-id/usb-046d_0809_33A881A3-video-index0 \
        -f alsa -ar 44100 -ac 2 -i default:CARD=Intel \
        -vcodec libx264 -crf 20 -threads 0 \
        -acodec aac -ab 32k -ar 44100 -ac 2 \
        -strict experimental \
        -vbsf h264_mp4toannexb \
        -absf aac_adtstoasc \
        -f mpegts udp://127.0.0.1:10001

And this is the command of the 2nd ffmpeg:

ffmpeg -muxdelay 15 -f mpegts -i udp://localhost:10001 -acodec copy -vcodec copy out.ts

Now, when I try to play the .ts file in VLC, I can watch the video, but in the message log I can see a lot of those:

main warning: late picture skipped (35805 > -268)
main warning: late picture skipped (2472 > -268)
main warning: late picture skipped (7218 > -262)
main warning: late picture skipped (1171 > -334)
main warning: late picture skipped (24818 > -266)
main warning: late picture skipped (19257 > -277)

main warning: late picture skipped (5374 > -265)
main warning: late picture skipped (1929 > -15969)
main warning: late picture skipped (1376 > -264)

I'm sure the network is not an issue here :) and also, I've monitored cpu usage (on a dual core) and it didn't go over 40% at any time.

Also, when I record a live stream this way for a very long time (like 12 hours or more) the audio and video get totally async, meaning audio is progressively advancing before the video and after like 3-4 hours of recording, the drift is around 10 seconds and will get even bigger for the longer period of the recording.

I can send you samples of .ts files, only I'll need to record for that long, so you can see that it really happens.

Other issues are related to remuxing from .ts to .flv (also with h264+aac), but I'll see to create new tickets for that.

  • Component changed from FFmpeg to undetermined

Assuming this is not reproducible with

ffmpeg -re -f video4linux2 -r 30 -s qvga -i /dev/v4l/by-id/usb-046d_0809_33A881A3-video-index0 -vcodec libx264 -crf 20 -vbsf h264_mp4toannexb out.ts

Isn't this more an udp issue?

And why are you using the bsf?

comment:2 Changed 5 years ago by burek

Well, I didn't try just recording to .ts file for that long, more rational way was to stream to an udp port because that way I could duplicate the data and watch it, while it is being saved to a file.

Anyway, for the absf, I don't remember now where exactly did I pick up that option (was it in ffmpeg channel or google), I just know that without it, when I play the udp stream in VLC, then the audio is a lot more quirky, skipping up/down-sampling and stuff... And since there is no official documentation on that filter ( http://ffmpeg.org/ffmpeg.html#aac_005fadtstoasc ), I didn't have chance to read about its real intended usage, so it might be the reason of the async behavior.

Can You give me one working example (default or something) of using mpegts (h264+aac) over udp, just to test it, because I've tried so many different combinations and variations I can't even remember now and none of them gave the smooth and clean playback without async (I'm talking about 100/100 LAN network). What could be the simplest way to start such a stream?

comment:3 Changed 5 years ago by cehoyos

I meant the video bitstream filter that should only make sense when stream copying from mp4.

To clarify:
Does creating the transport stream without using udp (and without audio and without the video bitstream filter) produce a file that does not show the warnings in vlc?

comment:4 Changed 5 years ago by burek

why without audio?

and yes, it does:

ffmpeg:

encoding audio only works just fine:

ffmpeg -y -re \
        -f alsa -ar 44100 -ac 2 -i default:CARD=Intel \
        -acodec aac -ab 32k -ar 44100 -ac 2 \
        -strict experimental \
        out.ts

No warnings, errors, nothin, just clear audio :)

comment:6 Changed 5 years ago by cehoyos

Is this only reproducible with an external library (-vcodec libx264) or also with an internal encoder?

Please post complete, uncut console output (including command line) without -threads 0.

And do you have any idea what the vlc warnings mean? Are there any visible problems with the resulting file? Do other players (ffplay, MPlayer, WMP 12) show any problems?

comment:7 Changed 5 years ago by burek

Same scenario with this example (mpeg2video):

ffmpeg -y -re \
        -f video4linux2 -r 30 -s qvga -i /dev/v4l/by-id/usb-046d_0809_33A881A3-video-index0 \

The problem still exists.
That message tells that the timestamps are somehow wrong, I guess. Sometimes I can see the image freezes for a fraction of a second and the image goes distorted just like a wrong keyframe was used for all the subsequent delta frames, but it gets back to normal after a couple of seconds.

Are the problems only reproducible with -vcodec mpeg2video -f mpegts or also for -vcodec mpeg2video -f avi/mpg/mkv ?

comment:9 Changed 5 years ago by burek

-vcodec mpeg2video -f avi: no warnings at all
-vcodec mpeg2video -f mpeg: warnings are there constantly, just like with mpegts
-vcodec mpeg2video -f matroska: no warnings at all

Is the problem also reproducible with

ffmpeg -f video4linux2 -i /dev/v4l/by-id/usb-046d_0809_33A881A3-video-index0 out.ts

?
Or is -r 30 needed to make the conversion work at all?

-r 30 just tells the driver to correctly sample the video input, so we don't have to resample it afterwards

here is the log:

I apologize, it seems that this error is related to a slow hardware (??) although I'm not sure why, because the cpu usage never gets over 30-40%, but they say its related to a slow decoder/cpu or something like that, so this bug report can be closed without further examination, I guess.
