From: Antonio Ospite Date: Tue, 27 Feb 2018 22:42:32 +0000 (+0100) Subject: am7xxx-play: remove any usage of ENOTSUP X-Git-Tag: v0.1.7~15 X-Git-Url: https://git.ao2.it/libam7xxx.git/commitdiff_plain/18978589ed6ae1ddef52ae892b2c224b545ec29a?ds=inline am7xxx-play: remove any usage of ENOTSUP There's really no need to use ENOTSUP here, the return value is not checked against the specific value, but just for the sign. Replacing it with EINVAL makes the code more aligned with the other error paths and also allows to remove a conditional define. --- diff --git a/examples/am7xxx-play.c b/examples/am7xxx-play.c index 7bad4f7..82954fc 100644 --- a/examples/am7xxx-play.c +++ b/examples/am7xxx-play.c @@ -36,13 +36,6 @@ #include -/* On some systems ENOTSUP is not defined, fallback to its value on - * linux which is equal to EOPNOTSUPP which is 95 - */ -#ifndef ENOTSUP -#define ENOTSUP 95 -#endif - static unsigned int run = 1; struct video_input_ctx { @@ -114,7 +107,7 @@ static int video_input_init(struct video_input_ctx *input_ctx, } if (video_index == -1) { fprintf(stderr, "cannot find any video streams\n"); - ret = -ENOTSUP; + ret = -EINVAL; goto cleanup; } @@ -122,7 +115,7 @@ static int video_input_init(struct video_input_ctx *input_ctx, input_codec_ctx = input_format_ctx->streams[video_index]->codec; if (input_codec_ctx == NULL) { fprintf(stderr, "input codec context is not valid\n"); - ret = -ENOTSUP; + ret = -EINVAL; goto cleanup; } @@ -130,7 +123,7 @@ static int video_input_init(struct video_input_ctx *input_ctx, input_codec = avcodec_find_decoder(input_codec_ctx->codec_id); if (input_codec == NULL) { fprintf(stderr, "input_codec is NULL!\n"); - ret = -ENOTSUP; + ret = -EINVAL; goto cleanup; } @@ -138,7 +131,7 @@ static int video_input_init(struct video_input_ctx *input_ctx, ret = avcodec_open2(input_codec_ctx, input_codec, NULL); if (ret < 0) { fprintf(stderr, "cannot open input codec\n"); - ret = -ENOTSUP; + ret = -EINVAL; goto cleanup; } @@ -245,7 +238,7 @@ static int video_output_init(struct video_output_ctx *output_ctx, output_codec = avcodec_find_encoder(output_codec_ctx->codec_id); if (output_codec == NULL) { fprintf(stderr, "cannot find output codec!\n"); - ret = -ENOTSUP; + ret = -EINVAL; goto cleanup; }
