Description
I tried to resample otr Videofiles to avchd so that the video can be played on my Sony TV.
Therefor the h.264 video in the avi container can be copied and the mp3 audio must be reencoded to ac3 audio. See logfile for details.
But on the TV I have bad audio and with windows mediaplayer or vlc the video is not smooth.

Replying to cehoyos:
Replying to kla960:
Comand line:
ffmpeg -i sample.avi -fflags +genpts -vcodec copy -acodec ac3 -y sample.ts
This command line looks different than the one from comment:2
Please post one minimal command line that allows to reproduce the issue together with the complete, uncut console output.
OK here the original line to the output
ffmpeg.exe -threads 4 -fflags +genpts -i ".\CutOriginale\Navy_CISL_A13.06.23_21-15_sat1_60_TVOON_DE.mpg.HQ.avi" -ss 341.04 -t 1353.8 -vcodec copy -acodec ac3 -ac 2 -ab 192k -y ".\Cut\Navy_CISL_A13.06.23_21-15_sat1_60_TVOON_DE.mpg.HQ.avi.Part1.ts" -ss 2233 -t 712.68 -vcodec copy -acodec ac3 -ac 2 -ab 192k -y ".\Cut\Navy_CISL_A13.06.23_21-15_sat1_60_TVOON_DE.mpg.HQ.avi.Part2.ts" -ss 3578.32 -t 353.4 -vcodec copy -acodec ac3 -ac 2 -ab 192k -y ".\Cut\Navy_CISL_A13.06.23_21-15_sat1_60_TVOON_DE.mpg.HQ.avi.Part3.ts"
But you can reproduce it in different ways. It always happend if you only reencode the audio!!!!

The shorter command line from comment:3 does not allow to reproduce the problem?
comment:9 by , 11 years ago
comment:10 by , 11 years ago
I asked for a failing command line and the complete, uncut console output in comment:1
You posted console output in comment:2 and a very short command line in comment:3
I believe the command and the console output do not match and wrote comment:6 - I was hoping you would use the short command line from comment:3 (assuming it does allow to reproduce the problem) and add the console output.
In comment:7 you added a very long command line with several options that look unrelated to your original problem.
If the simple and short command line allows to reproduce your original problem, please provide complete, uncut console output for it.

OK, here is what you request.

I originally missed your comment about non-smooth video, sorry!
Please provide an input sample that allows to reproduce the problem.

sample_avi_to_mpegts_with_reencoding_mp3_audio_to_ac3.avi is uploaded to the ftp server.

Does the Sony TV also support audio-only transport streams, ie does the following produce working output?
$ ffmpeg -i sample_avi_to_mpegts_with_reencoding_mp3_audio_to_ac3.avi -vn -acodec ac3 out.ts

Yes, it is supported and the sound of the audioonly file is ok. With video the audio is played with short interuptions.

Status: | new → open |
Summary: | avi to mpegts with reencoding mp3 audio to ac3 → remuxing h264 from avi to ts leads to stuttering with WMP |
Luckily this is reproducible without a specific TV, possibly related to ticket #2398 (and other h264-timestamp related tickets).

Sorry for not realizing this earlier:
The file you uploaded was created with FFmpeg. Please upload the original sample, ie the one you used as input for the FFmpeg command that created the avi file.

I uploaded a sample produced with
dd if=sample.avi of=sample_avi_to_mpegts_with_reencoding_mp3_audio_to_ac3.avi bs=1024 count=10000
but don't be suprised, it is also a file what was build with ffmpeg by the internet videoportal http://www.onlinetvrecorder.com/v2/
You can reproduce the problem with every HQ videofile.
To make this a valid ticket, please provide the command line that produces the "bad" audio together with the complete, uncut console output.
