Dotaz: Nejde mi vyrobit MPEG-4 s kodekem H264 pomocí Mencoderu.

[x]

Dobrý den. Pokouším se mencoderem vytvořit mpeg-4 s kodekem H264:

mencoder -ovc x264 -x264encopts bitrate=500 -vf hqdn3d=2:1:2 -oac mp3lame -lameopts vbr=3:br=96 /home/mircy/test.avi -of lavf -lavfopts format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -o /home/x/Documents/film.mp4

Mám 2 problémy:

1. Video nemá mnou požadovaný datový tok

2. Shazuje Kaffeine. (Xine drží, pokud jsem použil kontejner avi, šel do kytek i on).

Co mám špatně? Mencoder píše:

Bez té obskurní volby i_certify_that_my_video_stream_does_not_use_b_frames to také havaruje? Viz varování mencoderu:

Proč jí tam vlastně máte?

[x]

Bez ní to zhavaruje při pokusu o vytvoření MP4 - přesné znění si nepamatuji, ale tuto volbu si mencoder přímo vyžádal.

Zkusil jsem to znovu bez té volby:

==========================================================================
** MUXER_LAVF *****************************************************************
If you wish to use libavformat muxing, you must ensure that your video stream
does not contain B frames (out of order decoding) and specify:
    -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames
on the command line.

[David Ježek]

btw mas nejakej konkretni duvod proc to tlacit do mp4 a ne treba do mkv?

[David Ježek]

zvlast kdyz zvuk je trapna mp3 a ne ogg/aac. to uz rovnou muzes delat avi (ale radeji matrosku)

[x]

ACC to bude. MP4 pro to, že to "umí" Mencoder přímo. Ale vypadá to,, že to dám do MKV, když to jinak nepújde. Ale furt zůstává ten problém s datovým tokem.

[David Ježek]

btw, to ze nema pozadovany datovy tok znamena co?

1) hazi si to jak chce

2) je VZDY vetsi nez zadam

3) je VZDY mensi nez zadam

???

[x]

2) (12569.465 kbit/s)

[David Ježek]

UAAAA! pres 12000kbps tak to je narez! ja osobne pro x264 nastavuji pro 768x576 bitrate na 700±50kbps a je to akorat. tady bude imho chyba nekde v kodeku co je v mencoderu, nebo obecne v mencoderu

[David Ježek]

jinaxem se ted blize podival na ten tvuj log:

512x304 16bpp 29.970 fps 35168.4 kbps

zdroj ma tedy relativne nizke rozliseni, ale prekvapuje me ta mizerna barvna hlouba 16bit per pixel a NTSC-like 29,970fps ... z ceho pochazi ten zdroj?

[x]

To je jen videoklip odněkud z Internetu, převedené v rámci experimentů do AVI / HuffYUV. Tak jsem teď skusil jiný (nějaký MPG) - 9264.033 kbit/s.

[GeBu]

Jak se to pomocí mencoderu narve do matrošky?
