[FFmpeg-devel] [PATCH] MMS wrapper

[Geek.Song]

Dear:

I think you over-design the implementation, I just modify the
avio_open2() to probe mmsh or mmst.

int avio_open2(AVIOContext **s, const char *filename, int flags,
               const AVIOInterruptCB *int_cb, AVDictionary **options)
{
    URLContext *h;
    int err;
    int mms = !av_strncasecmp(filename, "mms://", 6);

    if (mms) {
        char mms_replace[1024] = {'\0'};
        const char *mms_surfix[] = {"mmsh://", "mmst://"};
        int i = 0, try_count = sizeof(mms_surfix)/sizeof(mms_surfix[0]);

        av_log(NULL, AV_LOG_WARNING, "Found ambiguous \"%s\"
stream\n", filename);
        while (i < try_count) {
            int size = strlen(mms_surfix[i]) + 1;

            av_strlcpy(mms_replace, mms_surfix[i], size);
            av_strlcat(mms_replace, filename + 6,  1024 - size);
            av_log(NULL, AV_LOG_INFO, "Try to use \"%s\" as
replacement\n", mms_replace);
            err = ffurl_open(&h, mms_replace, flags, int_cb, options);
            if (err < 0)
                av_log(NULL, AV_LOG_INFO, "Failed to open: \"%s\"\n",
mms_replace);
            else {
                err = ffio_fdopen(s, h);
                if (err < 0) {
                    ffurl_close(h);
                    return err;
                } else
                    return 0;
            }
            i++;
        }
        return err;
    }
    err = ffurl_open(&h, filename, flags, int_cb, options);
    if (err < 0)
        return err;
    err = ffio_fdopen(s, h);
    if (err < 0) {
        ffurl_close(h);
        return err;
    }
    return 0;
}
