Dotaz: Mplayer a CT1 MPEG-4 HD na dvb-t

[BigWrigley]

Ahoj vsem. Experimentuji s prijmem CT1 v HD v multiplexu C od O2. Bezne kanaly na ostatnich MUXech funguji mez problemu. Pri pokusu prehrat ten pokusny HD stream od 02 vsak hraje jen zvuk a Mplayer pise "no video". Tak si rikam, jestli to je tim, ze Mplayer ten HD MPEG4 stream: a) nevidi b) vidi, jen ho neumi dekodovat c) tam zrovna neni

Myslim, ze Mplayer by mel schopen dekodovat temer jakekoliv video, resp. minimalne neco prozradit.

Netusi nekdo, v jak to doopravdy je, resp. muze to nekdo vyzkouset i pod win? Podle ruznych diskuzi by to chodit melo (tedy, ze se vysila) i Mplayer by mel HD umet. Kaffeine se mimochodem chova uplne stejne.

S jakymi kodeky mas zkompilovany mplayer ??? Prehraje to vlc ?

[BigWrigley]

Mplayer je z debian-multimedia:

Kodeku ma v sobe asi tunu. Ani se to sem neodvazuji pastnout. Ktery je presne treba? Mpeg4ds,mpeg4 ffh264... VLC se tvari asi takhle: ma tendenci otevrit velike okno s obrazem, ale v zapeti spadne... MPEG2 program c.3 - bezi tam monoskop - prehraje

Aktualni VLC je 0.8.6c!

Mozna jsou tam krome bezpecnostnich vylepseni i nejake opravy/zlepseni ve smeru mpeg4. Zkousel jste tzap adapter0+ulozit, prekontrolovat kodek/prehrat?

[CIJOML]

Kdysi jsem to googloval a nasel jsem, ze ffmpeg zatim nepodporuje ten druh MPEG4 kodovani co O2 pouziva. Ale jestli to je nebo neni kec, netusim.

[svaca]

Hlavne ffmpeg se meni ze dne na den ....

[BigWrigley]

Jaky by to mel byt presne kodek ?

Dik A.

[BigWrigley]

Tak jsem trochu googlil:

Xserveru se jsem natvrdo pridal option Option "VideoRam" "65536"

a uz se ukazalo aspon cosi s obrazem, ale zase pro zmenu

Budu to zkoumat dal, ale ty kodeky asi jeste budou mit nejake musky...

[svaca]

Co mas za grafiku Matrox ?? 16 MB ? Jestli mas neco tekoveho, nebo orsi (vykonove) tek to proste nestiha ani ve 2D, pak musis snizit rozliseni + nastavit grafiku do 15 bitu ...

[Ctirad Feřtr]

Částečně správná připomínka. Ovšem problém mnohých straších karet s HD videem není v tom, že by to nestíhaly, ale v tom, že při použití xv mají omezené rozlišení na nějakých 1024x1024 (můj případ).

Tohle ale není ten problém, protože by výstup z mplayeru vypadal jinak. Tohle vypadá jako problém na straně demuxeru.

[BigWrigley]

Co mi neni uplne jasne, jak se u on-board karet urci velikost pameti. Hadam, ze se vezme to, co je v biosu prednastaveno jako sdilena pamet. A pripadne se to da upravit jeste nastavenim v xorg.conf. U me je to takhle:

Section "Device"
        Identifier      "Intel Corporation 82865G Integrated Graphics Controller"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Option          "UseFBDev"              "false"
        Option "VideoRam" "65536"
        Option "CacheLines" "1980"
        EndSection

Option CacheLines jsem vygooglil a bez ni vlc neotevre ani to okno s videem a hlasi chybu

X Error of failed request:  BadAlloc (insufficient resources for operation)

Jak jsem se dopatral, je tato option pro i810 driver, popis je napr. zde:

http://www.x.org/archive/X11R6.8.0/doc/i810.4.html

Option "CacheLines" "integer"

This allows the user to change the amount of graphics memory used for 2D acceleration and video. Decreasing this amount leaves more for 3D textures. Increasing it can improve 2D performance at the expense of 3D performance. Default: depends on the resolution, depth, and available video memory. The driver attempts to allocate at least enough to hold two DVD-sized YUV buffers by default. The default used for a specific configuration can be found by examining the Xorg log file.

Spis se tedy priklanim k nazoru, ze chyba bude nekde v dekodovani MPEG4 streamu. Ales

[Ash]

Ono to má jistou logiku, když to řvalo BadAlloc (insufficient resources for operation). Chce to neházet vždycky všechno hned na kodeky.

[jaha2x]

Kec to neni, ffmpeg ma problem s prokladanym 1080i, na rozdil od "plnohodnotneho" 1080p ... Druhy problemek je, ze Mplayeru se nelibi H.264 zabaleny v TS streamu, ceka tam MPEG2 a vysledkem je to "no video". VLC si pro zmenu se streamovanym H.264 "poradi", a po tom, kdyz jsem jeho vystup nasmeroval do souboru s "obalkou " MP4, misto puvod. TS, si s timto souborem "poradil" i mplayer. Kupodivu, VLC si neporadilo se zaznamenanym TS v souboru. Mplayer si "poradil" i kdyz jsem ze zaznamenaneho TS streamu vyextrahoval prislusny video ES. To poradil pisu v uvozovkach, protoze tim poradil myslim jen to, ze zdetekoval H264 a zacal neco prehravat - porad zde je problem s tim 1080i, viz:

#dvbstream -o:file.ts 1101 1102 1100 -f 818000000 -gi 8 -cr AUTO -crlp AUTO
#ts2es file.ts 1101 >file.h264
#mplayer -framedrop file.h264
...

[BigWrigley]

Diky za odpoved, konecne neco, ceho se da chytit a minimalne inspirace na dalsi experimentovani. Vyzkousim o vikendu a podelim se o zkusenosti.

[BigWrigley]

Tak jsem si s tim zase chvili hral a:

- zaznamenat ts pomoci dvbstream je ok. - ts2es v debianu neexistuje, binarka byla prejmenovana na ts_filter, nicmene vysledek nelze mplayerem prehrat - pomoci vlc a #es modulu jde vyseknout s ts jeden stream a ten ulozit do nove obalky mp4 - toto mplayer sice pozna, uz otevre i adekvatne velke okno a v zapeti crashne. Vypada to nejak takto:

Ty Xv hlasky jsou zpusobene tim, ze jsem si to vzdalene pustil pres ssh, pc okupuje manzelka...

Nicmene se zda, ze ten interlacing opravdu nefunguje...

[Ondřej Kuda]

Podle této zprávy na VLC fóru si člověk může VLC zkompilovat sám s opatchovaným ffmpeg (pro PAFF interlacing), nebo počkat na night build VLC.

[jaha2x]

Tak to vypada, ze par problemu, o kterych jsem psal, jako detekce h264 v ts streamu vyresila posledni verze MPlayer v1.0rc2 Pokud by to nefungovalo, muze byt problem, ze v ts streamu neni PMT stream ...

[SAM:]

Negativní, v MPlayer 1.0rc2-4.1.2 to dopadne takto:

Přehrávám dvb://Nova HD-test
dvb_tune Freq: 674000000
Detekován formát souboru TS.
NO VIDEO! AUDIO MPA(pid=620) NO SUBS (yet)!  PROGRAM N. 0

Přehrávám dvb://CT 1 (MPEG-4 HD)
dvb_tune Freq: 818000000
Detekován formát souboru TS.
NO VIDEO! AUDIO MPA(pid=1102) NO SUBS (yet)!  PROGRAM N. 0

Takže HD zatím bohužel.

[jaha2x]

to vypada spise na problem nascenovani, je v channels.conf neco jako toto?:

NovaHD-test:674000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_16:HIERARCHY_NONE:610:620:400

pokud tam neni 610 ale 0 tak je to spatne ...

Takhle nejak mi to fungovalo:

dvbstream -o 610 620 630 600 -f 674000000 -gi 8 -cr AUTO -crlp AUTO -rtp -d2 -ttl3 |mplayer -fps 25

610 video, 620 a 630 audio a 600 je pmt pokud mplayer v tom ts streamu nemel i ten pmt tak to stejne nefungovalo - povazoval tu 610 za mpeg2 ...

[SAM:]

to mě nějak nechodí ten dvbstream

dvbstream -o 610 620 630 600 -f 674000000 -gi 8 -cr AUTO -crlp AUTO -rtp -d2 -ttl3

Toto asi neni uplne dobre:

Takze zrejme nejaka nekompatibila ... Ja to testoval s dvbstream v0.6, tam to fungovalo ....

[mika]

Diky za info, ja tam nemel pid 610, a nemohl jsem to prehrat , stalo me to pul dne. takhle to funguje.

[CIJOML]

Zkusil sem dnesni SVN snapshoot MPlayeru (1.0rc2 nefunguje) a uz jde prehravat Nova HD:

Maybe you are playing a non-interleaved stream/file or the codec failed?

Obraz se mi uz zobrazi, ale je asi 2x pomalejsi nez zvuk (ten jde normalne). Je to proto, ze mi to nestiha, nebo, ze kodek neni jeste uplne v poradku? Mam dnesni mplayer.
