Ungashandura sei MKV Vhidhiyo Audio kubva kuDTS kuenda kuAAC3

Kune akawanda mamodheru e Smart TV, saka mupfungwa iyoyo pane chimwe chinhu pane zvese zvavanofarira, asi chokwadi ndechekuti vamwe vane zvirevo zvinoda kuziva maererano nemafomati akatsigirwa ekuberekesa zvemukati, uye zvinotitadzisa kuita zvakawanda. Nyaya yakajairika ndeyeye simba tamba mavhidhiyo eMKV ane odhiyo iri mune AC3 fomati asi isingakwanise kudaro kana iri muDTS fomati, chimwe chinhu icho ikozvino chatinozoona kugadzirisa.

Neraki mukati Linux isu tine dzimwe nzira dzezvese, uye imwe nzira yekutarisana nedambudziko iri kuburikidza nechinyorwa chinotibvumidza chinja odhiyo yeiyo MKV vhidhiyo kubva DTS kuenda AC3 otomatiki. Kuti tiite izvi, isu tinomhanya yedu yakasarudzika mameseji edhita (inogona kunge iri Gedit, senge yangu, Nano, Vi kana chero imwe):

gedit DTSaAC3.sh

Kana iyo faira yavhurwa, tinowedzera zvinotevera:

nice -15 ffmpeg -i $1 -y -vcodec copy -copyts -acodec ac3 -ab 192k \
-vbsf h264_mp4toannexb -sn -f matroska $2

Iye zvino isu tinofanirwa kumisikidza script seinokwanisika, yatinoita iyo inotevera:

sudo chmod +755 ./DTSaAC3.sh

Tichazotsanangura nenzira yekutanga mashandisiro anoita chinyorwa ichi: kune rumwe rutivi, nemutemo weNice pamwe chete neparamende -15 (tinogona zvakare kushandisa -10) tiri kuratidza kuti tinoda mhanyisa iyi script uine yakaderera kukoshaa, kuitira kuti isakanganisa mashandiro ekombuta uye chengetedza CPU kushandiswa kusapfuura 50%. Ipapo, isu tinoita kuraira ffmpeg pachezvayo, inova ndiyo inoita shanduko, uye sezvatinoona, zvinoratidzwa kuti vhidhiyo yasara isina kuchinjika (-vcodec kopi) nepo odhiyo ichichinjirwa kuac3 (-acodec ac3).

Zvino, kana tikanyatsotarisisa tichaona kuti zviripo matauriro maviri akafanana, $ 1 uye $ 2, ayo anoitirwa kuchengetedza yekuisa uye yekubuditsa mazita mazita zvichiteerana. Saka kana yedu yekutanga faira inonzi "PinkFloyd - TheWall.mkv" uye iri mu / kumba / fede / Kurodha pasi, tinofanirwa kuita rairo seinotevera:

./DTSaAC3 /home/fede/Descargas/PinkFloyd-TheWall.mkv PinkFloydTheWallAC3.mkv

Ndizvozvo, iko kutendeuka kuchatanga, uye mukati memaminitsi mashoma mashanu tichava nemuvhi yedu yakashandurwa kuita MKV asi neine odhiyo iri AC5 fomati.
