Problem with Audio Stream

Post by mav »

Hi,

I can play and cut my rec/ts-files. But I have problems with my files after coding in mp4 specially with the audio stream. Smart Cutter does not play the audio correctly, it is stumbling.

I have tried different modes: CBR/VBR, 128/192 kbps, normal and joint stereo and also simply copying the original audio stream from rec-file into the mp4-file.
Play and cut in Smart Cutter:
- the auto stream in the rec-file is Ok,
- the same auto stream in the mp4-file is stumbling.
There is one auto stream only.

Here are some codec infos:
General
Format : MPEG-4
Format profile : Base Media
Writing application : Lavf55.43.100
Format/Info : Advanced Video Codec
Writing library : x264 core 142 r2431
Encoding settings : cabac=1 / ref=2 / deblock=1:0:0 / analyse=0x1:0x131 / me=hex / subme=7 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=0 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=3 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=0 / b_adapt=1 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=abr / mbtree=1 / bitrate=2500 / ratetol=1.0 / qcomp=0.60 / qpmin=10 / qpmax=69 / qpstep=4 / vbv_maxrate=24000 / vbv_bufsize=24000 / nal_hrd=none / filler=0 / ip_ratio=1.40 / aq=1:1.00

Audio #1 (--> the same stream in rec-file and after coding in mp4-file!)
Format : MPEG Audio

What can I do?

Many thanks!

Dear mav:
Thanks for your message.

'after coding in mp4 specially with the audio stream. ... MPEG Audio'
May you please code the audio in MP4 into AAC audio format? That could by helpful with this issue.

Please feel free to send us your further advice and suggestion.
Thank you very much.
