I basically hacked fileffmpeg.C so it will allow me to choose mov flags for (cin-specific) qt 'format'. Of course one can rename all those qt profiles too... int FFOptionsFormatView::handle_event() { Asset *asset = fmt_config->asset; char *format_name = asset->fformat; char *replace_name = "mov"; if (!strcmp(format_name, "qt")) format_name = replace_name; // fixup avformat_free_context(fmt_ctx); fmt_ctx = 0; int ret = avformat_alloc_output_context2(&fmt_ctx, 0, format_name, 0); if( ret || !fmt_ctx ) { eprintf(_("no format named: %s"), format_name); ret = 1; } if( !ret ) fmt_config->start(fmt_ctx); return 1; } basically just three lines. But I have other changes for this file so diff will be not clean. === iff --git a/cinelerra-5.1/cinelerra/fileffmpeg.C b/cinelerra-5.1/cinelerra/fileffmpeg.C index ff206b10..d0d58290 100644 --- a/cinelerra-5.1/cinelerra/fileffmpeg.C +++ b/cinelerra-5.1/cinelerra/fileffmpeg.C @@ -1938,6 +1943,9 @@ int FFOptionsFormatView::handle_event() { Asset *asset = fmt_config->asset; char *format_name = asset->fformat; + char *replace_name = "mov"; + if (!strcmp(format_name, "qt")) + format_name = replace_name; // fixup avformat_free_context(fmt_ctx); fmt_ctx = 0; int ret = avformat_alloc_output_context2(&fmt_ctx, 0, format_name, 0); if( ret || !fmt_ctx ) { === I killed additional lines, but then linecount can be wrong ...
