[Ratkaistu]12.04 LTS ja mencoder h264-ongelma.

[kamara]

En ole onnistunut tekemään mencoderilla mpg:stä h264-videofilua.

Tämä tekee vain mustaa videota...

x264:n tulosteen perusteella sisältö on kyllä muutakin kuin pelkkää mustaa.

Miten toistat videotiedostoa? Huomaa, että nykyinen MPlayer ei välttämättä toista H.264 annex b:tä (.264, .h264) kunnolla, vaan video pitäisi ensin sijoittaa MP4- tai MKV-säiliöön.

[kamara]

Kuinkahan laitetaan mkv-säilöön, sillä se on lopullinen sijainti joka tapauksessa.

Tai kuinkahan laitetaan MP4:ksi?

Ääni menee ogg:na.

[nm]

Ääni menee ogg:na.

Silloin ainoa vaihtoehto on tosiaan MKV:

Koodia: [Valitse]

mkvmerge video.264 audio.ogg -o elokuva.mkv
Jos ääniraitaa ei vielä ole, jätä se vain lisäämättä tässä vaiheessa. Voit myös käyttää mkvmergen graafista käyttöliittymää (mmg, sijaitsee paketissa mkvtoolnix-gui).

[kamara]

Kiitos ratkaisusta. Itselleni oli yllätys, ettei .264 - päätettä tuntenut vlc eikä mendocer.

Lisäksi omassa scriptissäni oli muutama virhe, jonka takia ei tullut .mkv-tiedostoa.

Syyllinen oli lame, joka toimii hivenen eri tavalla tässä 12.4:ssä kuin 10.4:ssä.

Pienten muutosten jälkeen sainkin scriptini toimimaan.
