Prezados,

Embora ciente das considerações feitas previamente aqui em torno do uso de dispositivos USB, resolvi testar a sintonização de um que tenho aqui com chipset Dibcom já estamos considerando o kernel 2.6.35 com V4L/DVB (linuxtv).

Alterei o arquivo /usr/local/etc/ginga/files/tuner/isdbt.ini inserindo a frequência UHF da emissora desejada na região em que me encontro:

id 01 name EITV_HD     frequency 509143000 segment FULLSEG
id 01 name EITV_1SEG   frequency 509143000 segment 1SEG
id 04 name Globo_HD    frequency 563143000 segment FULLSEG
id 04 name Globo_1SEG  frequency 563143000 segment 1SEG
id 11 name SBT_1SEG    frequency 533143000 segment 1SEG
id 07 name BAND_HD     frequency 599143000 segment FULLSEG
id 07 name BAND_1SEG   frequency 599143000 segment 1SEG
id 13 name Record_1SEG frequency 623143000 segment 1SEG
id 02 name TV_Brasil   frequency 635143000 segment 1SEG
id 12 name GLOBO_HD    frequency 641143000 segment FULLSEG

Ao executar (conforme orientações descritas aqui), obtive um erro conforme log abaixo:

Segmentation fault

Não dediquei muito tempo para investigação do ocorrido mas, de fato, o arquivo mencionado não existe em qualquer parte do filesystem.

./usr/local/lib/ginga/iocontents/libgingaccsysctsimgdfb.so
./usr/local/lib/ginga/iocontents/libgingaccsysctsdfbav.so

./usr/local/lib/ginga/iocontents/libgingaccsysctsxineav.so
./usr/local/lib/ginga/iocontents/libgingaccsysctsfs.so

Como não tenho certeza de tal suporte nesta versão do VSTB, deixo aqui registrado o incidente.

Atenciosamente,
